Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Rachel Carson was bom in 1907 in Springsdale, Pennsylvania. She studied biology in college and zoology at Johns Hopkins University, where she received her master’s degree in 1933. In 1936, she was hired by the US Fish and Wildlife Service, where she worked most of her life.
Carson’s first book, Under the Sea Wind, was published in 1941. It received excellent reviews, but sales were poor until it was reissued in 1952. In that year, she published The Sea Around Us, which provided a fascinating look beneath the ocean’s surface, emphasizing human history as well as geology and marine biology. Her imagery and language had a poetic quality. Carson consulted no less than 1, 000 printed sources. She had voluminous correspondence and frequent discussions with experts in the field. However, she always realized the limitations of her non-technical readers.
In 1962, Carson published Silence Spring, a book that sparked considerable controversy. It proved how much harm was done by the uncontrolled, reckless use of insecticides. She detailed how they poison the food supply of animals, kill birds, and contaminate human food. At that time, spokesmen for the chemical industry mounted personal attacks against Carson and issued propaganda to indicate that her findings were flawed. However, her work was vindicated by a 1963 report of the President’s Science Advisory Committee.
According to the passage, what did Carson primarily study at Johns Hopkins University?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Henry is the undisputed star of Dronfield School near Sheffield. Whatever the achievements of other members of the comprehensive school, it is Henry, with his soulful eyes and glossy hair, who has hogged the limelight, appearing on television in Britain and abroad. Yet despite all the public adulation, Henry stirs up no envy or resentment among the 2000 students – in fact, they all adore him. The dog, who first arrived six months ago, is a super dog, who has improved students’ behaviour and encouraged more students to focus on their academic achievement.
Andrew Wainwright, a student at Dronfield School, says there is something magical and calming about being able to interact with Henry during his time at the school’s catch-up classes, and that if he falls behind, that opportunity will be denied. Even doubting staff have finally been won round. Perhaps that is because Henry, who lies on the floor during staff meetings, has also had a calming effect on them.
It was Andrew’s teacher, Wendy Brown and the school counsellor, Julie Smart, who first proposed buying a school dog. “Julie and I were talking one day about how looking after dogs can positively affect children’s conduct,” says Brown. “We did some research and discovered that the presence of pets has been shown to be therapeutic. A number of studies have shown that animals improve recovery after surgery or illness and have a calming influence on people in a lot of settings. Some of my kids can be a handful and some of the children Julie counsels have terrible problems.”
Could the school dog become a craze? Other schools such as the Mulberry Bush, a primary school for children with behavioural problems, have stepped forward to point out they already have one. Rosie Johnston, a Mulberry staff member has been bringing her golden retriever, Muskoka, into school for three years. Apart from being a calming influence, Muskoka even plays his part in literacy lessons. Children at the school can be too shy to read to adults so they read to Muskoka. “Their anxiety about mispronouncing something or getting the words in the wrong order is reduced when they read to him,” says Johnston.
Psychologist Dr Deborah Wells from Queen's University Belfast specialises in animal-human interaction. She believes that the underlying key to the Henry effect is that dogs offer unconditional love and that cheers up adults and children and helps with self-esteem. But traditionalist Chris Woodhead, the former chief inspector of schools says, “I don’t see why a teacher cannot create a positive learning environment through the subject they teach and their personality. Dogs strike me as a bit of a publicity stunt. It’s the kind of sentimental story journalists love.” Despite this sentiment, Henry remains as popular as ever.Which of the following best serves as the title for the passage?

The culture of Vietnam is one of the oldest in Southeast Asia, with the ancient Bronze age Đông Sơn culture being widely considered one of its most important progenitors. In spite of geographically Southeast Asian, Vietnamese culture was heavily influenced by Chinese culture in terms of politics, government, social and moral ethics, and art due to 1000 years of Chinese rule. Thus, Vietnam is considered to be part of the East Asian cultural sphere together with China, Japan, Korea and Taiwan.
Following independence from China in the 10th century, Vietnam began a southward expansion that saw the annexation of territories formerly belonging to the Champa Civilization (now Central Vietnam) and parts of the Khmer Empire (now Southern Vietnam). Gradually, there are minor regional variances in Vietnam's culture due to exposure to these different groups.
During the French colonial period, Vietnamese culture absorbed various influences from the Europeans, including the spread of Catholicism and the adoption of the Latin alphabet. Prior to this, Vietnamese had used both Chinese characters and a script called Chữ Nôm which was based on Chinese but included newly invented characters to represent native Vietnamese words.
In the socialist era, the cultural life of Vietnam has been deeply influenced by government-controlled media and the cultural influences of socialist programs. For many decades, foreign cultural influences from the Western World were shunned, and emphasis was placed on sharing the culture of communist nations such as those in the Soviet Union, Cuba, China, and others.
Some elements generally considered to be characteristic of Vietnamese culture include ancestor veneration, respect for community and family values, handicrafts and manual labour, and devotion to study. Important symbols present in Vietnamese culture include dragons, turtles, lotuses, and bamboo.
Which statement is true about the socialist era?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
A letter of application is a sales letter in which you are both salesperson and product, for the purpose of an application is to attract an employer’s attention and persuade him or her to grant you an interview. To do this, the letter presents what you can offer the employer, rather than what you want from the job.
Like a resume, the letter of application is a sample of your work and an opportunity to demonstrate your skills and personality. If it is written with flair and understanding and prepared with prefessional care, it is likely to be very effective. While the resume must be factual, objective, and brief, the letter is your chance to interpret and expand. It should state explicitly how your background relates to the specific job, and it should emphasise your strongest and most relevant characteristics. The letter should demonstrate that you know both yourself and the company.
The letter of application must communicate your ambition and enthusiasm. Yet it must be modest. It should be neither aggressive nor compliant: neither pat yourself on the back nor ask for sympathy. It should never express dissatisfaction with the present or former job or employer. And you should avoid discussing your reasons for leaving your last job.
Finally, it is best that you not broach the subject on salary. Indeed, even if a job advertisement requires that you mention your salary requirements, it is advisable simply to call them “negotiable.” However, when you go on an interview, you should be prepared to mention a salary range. For this reason, you should investigate both your field and, if possible, the particular company. You don’t want to ask for less than you deserve or more than is reasonable.The word “broach” in paragraph 4 is closest in meaning to .

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
The Internet started out as a limited network called the ARPANET (Advanced Research Projects Agency Network). It was a network of computers that allowed communication even if computer became non- functioning. It was the academic and scientific community that adopted Internet, using a protocol called TCP/IP. TCP/IP allows a number of different network computers to be connected together. This is called the Internet. The Internet allows the creation the World Wide Web or the Web for short. The Web consists of Internet sites that allow data to be shared by others. Aside from making the Web possible, the Internet also makes e-mail, chat rom and file-sharing and telephoning possible. It even allows people to watch media and play games.
The Web can be read in a browser. A browser is simply a software program that uses HTTP (Hyper Text Transfer Protocol) data transmission. This will allow you to view Web pages. HTTP let you browser read the text, graphics, animation, video and music that are on the Web page. It also enables you to click on a link on the page using the mouse. The links on a Web page that guide you to go from one Web page to another are called hyperlinks. A Web page usually contains many hyperlinks so that you can “browse” the Internet. It is much like reading a book. You can go from page to page and get new information. One example of a browser is Internet Explorer. In the address box of your browser, you can type in an address called a URL for “uniform resource locator”.
To be able to use the Internet, you must have a computer with an Internet connection and software that lets you view that Web pages. Internet connection is called a dial-up connection. It needs the use of your telephone to connect your computer to an Internet service. A faster type of connection is called broadband. This requires a cable or some other equipment. If you turn on the computer with a broadband connection, it connects you the Internet at a time.What is the main idea of the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Lighthouses are towers with strong lights that help mariners plot their position, inform them that land is near, and warn them of dangerous rocks and reefs. They are placed at prominent points on the coast and on islands, reefs, and sandbars.
Every lighthouse has a distinctive pattern of light known as its characteristic. There are five basic characteristics: fixed, flashing, occulting, group flashing, and group occulting. A fixed signal is a steady beam. A flashing signal has periods of darkness longer than periods of light, while an occulting signal’s periods of light are longer. A group-flashing light gives off two or more flashes at regular intervals, and a group - occulting signal consists of a fixed light with two or more periods of darkness at regular intervals. Some lighthouses use lights of different colors as well, and today, most lighthouses are also equipped with radio beacons. The three types of apparatus used to produce the signals are the catoptric, in which metal is used to reflect the light; the dioptric, in which glass is used; and the catadioptric, in which both glass and metal are used.
In the daytime, lighthouses can usually be identified by their structure alone. The most typical structure is a tower tapering at the top, but some, such as the Bastion Lighthouse on the Saint Lawrence River, are shaped like pyramids, and others, such as the Race Rock light, look like wooden houses sitting on high platforms. Still others, such as The American Shoal lighthouse off the Florida Coast, are skeletal towers of steel. Where lighthouses might be contused in daylight, they can be distinguished by day- marker patterns - designed of checks and stripes painted in vivid colors on lighthouse walls.
In the past, the job of lighthouse keeper was lonely and difficult if somewhat romantic. Lighthouse keepers put in hours of tedious work maintaining the lights. Today, lighthouses are almost entirely automated with humans supplying only occasional maintenance. Because of improvements in navigational technology, the importance of lighthouses has diminished. There are only about 340
functioning lighthouses in existence in the United States today, compared to about 1,500 in 1900, and there are only about 1,400 functioning lighthouses outside the United States. Some decommissioned lighthouses have been preserved as historical monument.According to the passage, what kind of signal has long periods of light that are regularly broken by two or more periods of darkness?

Read the passage carefully and choose the correct answer.
“Where is the university?” is a question many visitors to Cambridge ask, but no one can give them a clear answer, for there is no wall to be found around the university. The university is the city. You can find the classroom buildings, libraries, museums and offices of the university all over the city. And most of its members are the students and teachers or professors of the thirty-one colleges. Cambridge is already a developing town long before the first students and teachers arrived 800 years ago. It grew up by the river Granta, as the Cam was once called. A bridge was built over the river as early as 875.
In the fourteenth and fifteenth centuries, more and more land was used for college buildings. The town grew faster in the nineteenth century after the opening of the railway in 1845. Cambridge became a city in 1951 and now it has the population of over 100000. Many young students want to study at Cambridge. Thousands of people from all over the world come to visit the university town. It has become a famous place all around the world.
Around what time did the university begin to appear?

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
The blue whale is the largest animal ever known to have existed. During the 20th century, the species was almost exterminated due to commercial whaling. The species has slowly recovered following the global whaling ban but it remains endangered and faces a number of serious threats including ship strikes and the impact of climate change.
Blue whales are simply enormous with most ranging in length from 24-30 m. The largest ever recorded was a gargantuan 33.5 m long. Females are up to 10 m longer than males. And they can weigh up to 200 tonnes. Just to put that in perspective: an adult male African elephant weighs 6 tonnes. The blue whale's heart is the size of a small car and its beat can be detected two miles away. But that's nothing compared to their calls. Blue whales are the loudest animals on earth and their calls are louder than a jet engine: reaching 188 decibels, while a jet's engine hit 'just' 140 decibels. Apart from their gigantic size, blue whales can be identified by their relatively small dorsal fin, a fairly rounded rostrum (anterior part of the skull), and approximately 90 ventral grooves, which reach the navel. They also have row of 300-400 baleen plates on each side of the mouth, which are black in color and range in length from 50 cm in front to 100 cm in back.
Blue whales mostly travel alone or in groups of 2-3. Larger groups of up to 60 whales have been reported and are probably associated with feeding grounds. However, the blue whale has the most powerful voice in the animal kingdom and its low-frequency sounds can travel in deep water over hundreds, or even thousands, of miles. Under these circumstances, animals which may appear to us to be traveling alone may actually be in constant contact with one another.
At birth, a blue whale calf is the largest baby on earth: approximately 8m long and weighing about 4 tonnes. They grow at a rate of 90 kg per day and wean after 7-8 months, once they have reached about 15 m in length, and are able to follow the normal migration pattern alone. They reach sexual maturity at 5-10 years. This growth rate is astonishing and is probably the fastest in the animal kingdom. From conception to weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the blue whale has no teeth so it is hard to tell its age but scientists believe they live until at least 50.
Like other large whales, blue whales are threatened by chemical and sound pollution, habitat loss, overfishing of krill, ship strikes and becoming entangled in fishing gear. Climate change could also have a major impact on its food supply, since global warming and associated ocean acidification may impact krill populations. In addition, frontal zones - critical whale habitats - are projected to move further south due to climate change. Frontal zones are boundaries between different water masses, where water can rise from the depths, bringing with it large amounts of nutrients that stimulate the growth of phytoplankton and support substantial populations of prey species for whales. Blue whales would have to migrate further (perhaps 200-500 km more) to reach and feed at these food-rich areas where they build up reserves to sustain themselves for the rest of the year. These longer migration paths could increase the energy costs of migration and reduce the duration of the main feeding season. As frontal zones move southward, they also move closer together, reducing the overall area of foraging habitat available.What is the purpose of the author in the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
In the explosion of the linguistic life cycle, it is apparent that it is much more difficult to learn a second language in adulthood than a first language in childhood. Most adults never completely master a foreign language, especially in Phonology – hence the ubiquitous foreign accent. Their development often “fossilizes” into permanent error patterns that no teaching or correction can undo. Of course, there are great individual differences, which depend on effort, attitudes, amount of exposure, quality of teaching and plain talent, but there seems to be a cap for the best adults in the best circumstances
Many explanations have been advanced for children’s superiority; they exploit Motherese (the simplified, repetitive conversation between parents and children), make errors unself- consciously, are more motivated to communicate, like to conform, are not set in their ways, and have not first language to interfere. But some of these accounts are unlikely, based on what is known about how language acquisition works. Recent evidence is calling these social and motivation explanations into doubt. Holding every other factor constant, a key factor stands out: sheer age
Systematic evidence comes from the psychologist Elissa Newport and her colleagues. They tested Korean and Chinese – born students at the University of Illinois who had spent a least ten years in the United States. The immigrants were give a list of 276 simple English sentences, half of them containing some grammatical error. The immigrants who came to the United States between the age of 3 and 7 performed identically to American – born students. Those who arrived between ages 8 and 15 did worse the latter they arrived, and those who arrived between 17 and 39 did the worst of all, and showed huge variability unrelated to their age of arrival.The passage mainly discussed

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
We get great pleasure from reading. The more advanced a man is, the greater delight he will find in reading. The ordinary man may think that subjects like philosophy or science are very difficult and that if philosophers and scientists read these subjects, it is not for pleasure. But this is not true. The mathematician finds the same pleasure in his mathematics as the school boy in an adventure story. For both, it is a play of the imagination, a mental recreation and exercise.
The pleasure derived from this activity is common to all kinds of reading. But different types of books give us different types of pleasure. First in order of popularity is novel-reading. Novels contain pictures of imaginary people in imaginary situations, and give us an opportunity of escaping into a new world very much like our world and yet different from it. Here we seem to live a new life, and the experience of this new life gives us a thrill of pleasure.
Next in order of popularity are travel books, biographies and memoirs. These tell us tales of places we have not seen and of great men in whom we are interested. Some of these books are as wonderful as novels, and they have an added value that they are true. Such books give us knowledge, and we also find immense pleasure in knowing details of lands we have not seen and of great men we have only heard of.
Reading is one of the greatest enjoyments of life. To book-lovers, nothing is more fascinating than a favorite book. And, the ordinary educated man who is interested and absorbed in his daily occupation wants to occasionally escape from his drudgery into the wonderland of books for recreation and refreshment.

They call Jamaica the "Island in the sun" and that is my memory of it. Of sunshine, warmth and abundant fruit that was growing everywhere, and of love. There were two sisters ahead of me in the family, and though of course I didn't know it, there was an exciting talk of emigration, possibly to Canada but more usually to England, the land of opportunity. I guess that plans were already being made when I was born, for a year or so later my Dad left for London. Two years after that my mum went as well and my sisters and I were left in the care of my grandmother.
Emigrating to better yourself was a dream for most Jamaicans, a dream many were determined to fulfill. Families were close and grandmothers were an important part of the family. So, when the mass emigrations began, it seemed perfectly right and natural for them to take over the running of families left behind.
Grandmothers are often strict, but usually also spoil you. She ran the family like a military operation: each of us, no matter how young, had our tasks. Every morning, before we went to school, we all had to take a bucket appropriate to our size and run a relay from the communal tap to the barrels until they are full. My sisters had to sweep the yard before they went to school. My grandmother would give orders to the eldest and these were passed down- as I got older I found this particularly annoying! But I can tell you, no one avoided their duties.
My Dad came over from England to see how we were getting on . He talked to us about the new country, about snow, about the huge city, and we all wanted to know more, to see what it was like. I didn't know it at that time., but he had come to prepare us for the move to England. Six months later my grandmother told me that I was going to join my parents and that she, too, was emigrating.
London was strange and disappointing. There was no gold on the pavements, as the stories in Jaimaica had indicated. The roads were busy, the buildings were grey and dull, with many tall, high-rise blocks. It was totally unlike Jamaica, the houses all small and packed close together. In my grandmother's house I had a big bedroom, here I had to share.
Then came the biggest shock: snow. While flakes came out of the sky and Dad smiled, pointed and said: "That's snow!" I rushed outside, looked up and opened my mouth to let the flakes drop in. The snow settled on my tongue and it was so cold that I cried. My toes lost all feeling. As my shoes and socks got wet and frozen, there came an excruciating pain and I cried with the intensity of it. I didn't know what was happening to me.

Martin Luther King, Jf, is well- known for his work in civil rights and for his many famous speeches, among which is his moving “I have a dream” speech. But fewer people know much about King’s childhooD. M.L., as he was called, was bom in 1929 in Atlanta, Georgia, at the home of his maternal grandfather. M.L.’s grandfather purchased their home on Auburn Avenue in 1909, twenty years before M.L was bom. His grandfather allowed the house to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. M.L. grew up in the atmosphere, with his home being used as a community gathering place, and was no doubt influenced by it.
M.L.’s childhood was not especially eventfully. His father was a minister and his mother was a musician. He was the second of three children, and he attended all black schools in a black neighborhood. The neighborhood was not poor, however. Auburn Avenue was an area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers, and other businesses and services. Even in the face of Atlanta’s segregation, the district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice that was a huge barrier keeping black Atlantans from mingling with whites.Which of the following statements is NOT true?

Transportation accounts for up to one–third of greenhouse gas emissions from the world’s biggest cities and traffic is the largest source of toxic air pollution. To create sustainable, healthy and liveable cities, we need to increase the number of cyclists on our streets, and that means getting more women on their bikes. In San Francisco, only 29% of cyclists are women; in Barcelona, there are three male cyclists for every female cyclist; in London, 37% of cyclists are female.
Surveys reveal that potential cyclists of all genders are deterred by similar concerns, including aggressive and speeding drivers, the threat posed by large vehicles such as lorries and buses, and bike theft. However, women disproportionately view protected cycle lanes as a more urgent priority.
According to research about women and cycling in San Francisco, cities should invest in protected cycle lanes with consistent and clear signage that function as a joined–up network to encourage female riders. Together with more secure cycle parking, these infrastructure investments would make cycling safer, supporting those who already cycle and encouraging those who do not yet ride.
People do what they perceive to be possible. Research in San Francisco found that women, especially women of colour, felt that “people like me” do not cycle. Similarly, 49% of people in London say they do not feel cycling is for “people like them”. More diverse and inclusive imagery of cyclists (in policy documents, in the media and on city streets) could help challenge these perceptions and make more people feel that cycling is for everyone. Social events that enable women to try cycling in a relaxed environment, perhaps as part of a buddy or mentor system that pairs experienced cyclists with those newer to cycling, can help make cycling more accessible and inclusive, along with approaches such as female–led maintenance classes.
The different decisions men and women make about cycling are not only based on issues of convenience or comfort. People’s perceptions of safety influence how, when, where and why they travel. Women and girls learn early on to worry about their personal safety when out and about, and to change their behaviour, dress, speech and travel patterns to avoid sexual harassment or violence. Cities must take women’s and girls’ safety considerations seriously through initiatives such as safety audits.The word “their” in paragraph 4 refers to .

Nowadays, most people realize that it’s risky to use credit card numbers online. However, from time to time, we all use passwords and government ID numbers on the Internet. We think we are safe, but that may not be true! A new kind of attack is being used by dishonest people to steal IDs and credit card numbers from innocent websurfers. This new kind of attack is called “phishing.”
Phishing sounds the same as the word “fishing,” and it implies that a thief is trying to lure people into giving away valuable information. Like real fishermen, phishers use bait in the form of great online deals or services. For example, phishers might use fake emails and false websites to con people into revealing credit card numbers, account usernames, and passwords. They imitate well-known banks, online sellers, and credit card companies. Successful phishers may convince as many as five percent of the people they contact to respond and give away their personal financial information.
Is this really a big problem? Actually, tricking five percent of the online population is huge! Currently, more than 350 million people have access to the Internet, and seventy-five percent of those Internet users live in the wealthiest countries on Earth. It has been estimated that phishers send more than three billion scam messages each year. Even by tricking only five percent of the people, phishers can make a lot of money.
Since there is so much money to make through this kind of scam, it has caught the interest of more than just small-time crooks. Recently, police tracked down members of an organized phishing group in Eastern Europe, who had stolen hundreds of thousands of dollars from people online. The group created official-looking email messages requesting people to update their personal information at an international bank’s website. However, the link to the bank in the message actually sent people to the phishers’ fake website. To make matters worse, further investigation revealed that this group had connections to a major crime gang in Russia.
How can innocent people protect themselves? Above all, they have to learn to recognize email that has been sent by a phisher. Always be wary of any email with urgent requests for personal financial information. Phishers typically write upsetting or exciting, but fake, statements in their emails so that people will reply right away. Also, messages from phishers will not address recipients by name because they really don’t know who the recipients are yet. On the other hand, valid messages from your bank or other companies you normally deal with will typically include your name.Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the question.

Where one stage of child development has been left out, or not sufficiently experienced, the child may have to go back and capture the experience of it. A good home makes this possible
- for example, by providing the opportunity for the child to play with a clockwork car or toy railway train up to any age if he still needs to do so. This principle, in fact, underlies all psychological treatment of children in difficulties with their development, and is the basic of work in child clinics.
The beginnings of discipline are in the nursery. Even the youngest baby is taught by gradual stages to wait for food, to sleep and wake at regular intervals and so on. If the child feels the world around him is a warm and friendly one, he slowly accepts its rhythm and accustoms himself to conforming to its demands. Learning to wait for things, particularly for food, is a very important element in upbringing, and is achieved successfully only if too great demands are not made before the child can understand them. Every parent watches eagerly the child's acquisition of each new skill: the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of anxiety in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural zest for life and his desire to find out new things for himself.
Learning together is a fruitful source of relationship between children and parents. By playing together, parents learn more about their children and children learn more from their parents. Toys and games which both parents and children can share are an important means of achieving this co-operation. Building-block toys, jigsaw puzzles and crosswords are good examples.
Parents vary greatly in their degree of strictness or indulgence towards their children. Some may be especially strict in money matters; others are severe over times of coming home at night, punctuality for meals or personal cleanliness. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness and well-being.
With regard to the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that“Example is better than precept”. If they are hypocritical and do not practice what they preach, their children may grow confused and emotionally insecure when they grow old enough to think for themselves, and realize they have been, to some extent, deceived. A sudden awareness of a marked difference between their parents' ethics and their morals can be a dangerous disillusion.Learning to wait for things is successfully taught .

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Because geologists have long indicated that fossil fuels will not last indefinitely, the U.S government finally acknowledged that sooner or later other energy sources would be needed and, as a result, turned its attention to nuclear power. It was anticipated that nuclear power plants could supply electricity in such large amounts and so inexpensively that they would be integrated into an economy in which electricity would take over virtually all fuel-generating functions at nominal cost. Thus, the government subsidized the promotion of commercial nuclear power plants and authorized their construction by utility companies. In the 1960s and early 1970s, the public accepted the notion of electricity being generated by nuclear power plants in or near residential areas. By 1975, 54 plants were fully operational, supplying 11 percent of the nation’s electricity, and another 167 plants were at various stages of planning and construction. Officials estimated that by 1990 hundreds of plants would be on line, and by the turn of the century as many as 1000 plants would be in working order.
Since 1975, this outlook and this estimation have changed drastically, and many utilizes have cancelled existing orders. In some cases, construction was terminated even after billions of dollars had already been invested. After being completed and licensed at a cost of almost $6 billion, the Shoreham Power Plant on Long Island was turned over to the state of New York to be dismantled without ever having generated electric power. The reason was that residents and state authorities deemed that there was no possibility of evacuating residents from the area should an accident occur.
Just 68 of those plants under way in 1975 have been completed, and another 3 are still under construction. Therefore, it appears that in the mid1990s 124 nuclear power plants in the nation will be in operation, generating about 18 percent of the nation’s electricity, a figure that will undoubtedly decline as relatively outdated plants are shut down.In line 7, the word “notion” is closet in meaning to

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:
Garbage cans are not magical portals. Trash does not disappear when you toss it in a can. Yet, the average American throws away an estimated 1,600 pounds of waste each year. If there are no magic garbage fairies, where does all that trash go? There are four methods to managing waste:
Recycling, landfilling, composting, and incinerating. Each method has its strengths and weaknesses. Let’s take a quick look at each.
Recycling is the process of turning waste into new materials. For example, used paper can be turned into paperboard, which can be used to make book covers. Recycling can reduce pollution, save materials, and lower energy use. Yet, some argue that recycling wastes energy. They believe that collecting, processing, and converti g waste uses more energy than it saves. Still, most people agree that recycling is better for the planet
than landfilling.
Landfilling is the oldest method of managing waste. In its simplest form, landfilling is when people bury garbage in a hole. Over time the practice of landfilling has advanced. Garbage is compacted before it is thrown into the hole. In this way more garbage can fit in each landfill. Large liners are placed in the bottom of landfills so that toxic garbage juice doesn't get into the ground water. Sadly, these liners don't always work. Landfills may pollute the local water supply. Not to mention that all of that garbage stinks. Nobody wants to live next to a landfill. This makes it hard to find new locations for landfills.
Compositing is when people pile up organic matter, such as food waste, and allow it to decompose. The product of this decomposition is compost. Compost can be added to the soil to make the soil richer and better for growing crops. While composting is easy to do onsite somewhere, like home or school, it's hard to do after the garbage gets all mixed up. This is because plastic and other inorganic materials must be removed from the compost pile or they will pollute the soil. There's a lot of plastic in garbage, which makes it hard to compost on a large scale.
One thing that is easier to do is burning garbage. There are two main ways to incinerate waste. The first is to create or harvest a fuel from the waste, such as methane gas, and burn the fuel. The second is to burn the waste directly. The heat from the incineration process can boil water, which can power steam generators. Unfortunately, burning garbage pollutes the air. Also, some critics worry that incinerators destroy valuable resources that could be recycled.
Usually, the community in which you live manages waste. Once you put your garbage in that can, what happens to fit is beyond your control. But you can make choices while it is still in your possession. You can choose to recycle, you can choose to compost, or you can choose to let someone else deal with it. The choice is yours.Which conclusion could be drawn from the passage?

Recreational diving or sport diving is a type of diving that uses scuba equipment for the purpose of leisure and enjoyment. In some diving circles, the term "recreational diving" is used in contradistinction to "technical diving", a more demanding aspect of the sport which requires greater levels of training, experience and equipment.
Recreational scuba diving grew out of related activities such as snorkeling and underwater hunting. For a long time, recreational underwater excursions were limited by the amount of breath that could be held. However, the invention of the aqualung in 1943 by Jacques-Yves Cousteau and its development over subsequent years led to a revolution in recreational diving. However, for much of the 1950s and early1960s, recreational scuba diving was a sport limited to those who were able to afford or make their own kit, and prepared to undergo intensive training to use it. As the sport became more popular, manufacturers became aware of the potential market, and equipment began to appear that was easy to use, affordable and reliable. Continued advances in' SCUBA technology, such as buoyancy compensators, modern diving regulators, wet or dry suits, and dive computers, increased the safety, comfort and convenience of the gear encouraging more people to train and use it.
Until the early 1950s, navies and other organizations performing professional diving were the only providers of diver training, but only for their own personnel and only using their own types of equipment. There were no training courses available to civilians who bought the first scuba equipment. Professional instruction started in 1959 when the non-profit National Association of Underwater Instructors was formed.
Further developments in technology have reduced the cost of training and diving. Scuba- diving has become a popular leisure activity, and many diving locations have some form of dive shop presence that can offer air fills, equipment and training. In tropical and sub-tropical parts of the world, there is a large market in holiday divers, who train and dive while on holiday, but rarely dive close to home. Generally, recreational diving depths are limited to a maximum of between 30 and 40 meters (100 and 130 feet), beyond which a variety of safety issues make it unsafe to dive using recreation diving equipment and practices, and specialized training and equipment for technical diving are needed.Recreational underwater excursions used to be limited _.
