Although people drive in all countries, the rules can be quite different between nations and areas. For this reason, you should always learn the laws before you decide to drive in a foreign country. If you are not careful, you can get into trouble since the rules might be very different from what you are used to. For example, you can find some big differences in laws related to the minimum driving age, the appropriate side of the road to drive on, and mobile phone use while driving.
In the U.S., people who live in Alaska may obtain a learner’s permit (legal permission to drive while being supervised) at the age of fourteen. This is quite different from the driving laws of Niger, where a person must be at least twenty-three years old to drive. If you are inquisitive to know the minimum driving age in most countries, the answer is eighteen. It may also surprise you to learn that not every country allows its citizens to drive, although most of them do. For example, women are not allowed to drive in Saudi Arabia no matter how old they are. Instead, they must have a male family member or hired male driver to travel by car.
Driving on the right or left side of the road also varies. For instance, in Great Britain, Cyprus, Australia, India, and Malaysia people drive on the left. However, in the U.S., Mexico, France, and Canada people are required to drive on the right. As a matter of fact, one country can have different driving rules for different areas. People in Hong Kong drive on the left, while drivers in other parts of China use the right side of the road.
Other driving laws that are different between countries include those related to using mobile phones. In Japan, using any kind of mobile phone device is illegal, even if you do not need to hold the phone with your hands. However, in Argentina and Australia, drivers are allowed to talk on their mobile phones as long as they do not use their hands.
You might also find it interesting to learn that some countries have very unusual laws. For example, in the country of Cyprus, it is against the law to eat or drink anything while driving. Even more interesting is that in Germany, there is a famous road called the Autobahn, where certain parts have no speed limit at all!The word “those” in paragraph 4 refers to_______.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.
The past fifty years or so have seen the gradual disappearance of animals from this earth, fishes from the sea, trees and plants from the land.
Many factors result in this unpleasant phenomenon. Among them, hunting is the main factor that endangers wildlife. Some people kill wildlife for sport. They take pleasure in collecting heads and hides. Yet others specialize in commercial hunting like killing whales.Apart from this, the rapidly growing human population threatens wildlife on land, too. Towns expand and roads have to be built, so forests are burnt and trees are chopped down. It seems that man needs every inch of land within his reach, so he moves on to the natural habitat of wildlife. Tigers, lions and leopards slowly die off without the food and shelter that the forests provide.
In addition, rapid urbanization means industrial expansion. Very often, poisonous chemicals, industrial wastes and oil are dumped into the rivers and seas. Fish and birds are threatened.
Many depend greatly on animals for survival. He needs their flesh, hides and furs. Thus, man cannot do without wildlife; or he himself would become extinct. The public should be made aware that it would be better to shoot the animals with a camera than with a gun. In this way, they can preserve and help wildlife to continue living rather than to move all signs of it.
Man must learn to farm the sea as he does the land. He should regulate the amount of frequency of his catch. He should allow fish to breed and multiply before netting them. A man also needs to build forest reserves, and to pass a law prohibiting the killing of animals, especially those that already rare. To retain the present animal kingdom, the least that man can do is to clean the seas and rivers to prevent pollution. The cycle of nature is such that it forms a vicious circle. The insecticides and pesticides that we spray on crops can kill the birds and animals that feed on them. When a man eats these poisoned animals, he himself can die. We must therefore test the chemicals to be used before they are sprayed or it might mean the death of man!According to the passage, what has happened to the wildlife in the past fifty years or so?

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 Winterthur Museum is a collection and a house. There are many museums devoted to the decorative arts and many house museums, but rarely in the United States is a great collection displayed in a great country house. Passing through successive generations of a single family, Winterthur has been a private estate for more than a century. Even after the extensive renovations made to it between 1929 and 1931, the house remained a family residence. This fact is of importance to the atmosphere and effect of the museum. The impression of a lived-in house is apparent to the visitor: the rooms look as if they were vacated only a short while ago whether by the original owners of the furniture or the most recent residents of the house can be a matter of personal interpretation. Winterthur remains, then, a house in which a collection of furniture and architectural elements has been assembled. Like an English country house, it is an organic structure; the house, as well as the collection and manner of displaying it to the visitor, has changed over the years. The changes have coincided with developing concepts of the American arts, increased knowledge on the part of collectors and students, and a progression toward the achievement of a historical effect in period-room displays. The rooms at Winterthur have followed this current, yet still retained the character of a private house.
The concept of a period room as a display technique has developed gradually over the years in an effort to present works of art in a context that would show them to greater effect and would give them more meaning for the viewer. Comparable to the habitat group in a natural history museum, the period room represents the decorative arts in a lively and interesting manner and provides an opportunity to assemble objects related by style, date, or place of manufacture.The word "developing" in line 11 is closest in meaning to ________ .

Choose the item among A, B, C or D that best answers the question about the passage:
"The United Nations (UN), international organization of countries created to promote world peace and cooperation. The UN was founded after World War II ended in 1945. Its mission is to maintain world peace, develop good relations between countries, promote cooperation in solving the world’s problems, and encourage respect for human rights.
The UN is an organization of countries that agree to cooperate with one another. It brings together countries that are rich and poor, large and small, and have different social and political Systems. Member nations pledge to settle their disputes peacefully, to refrain from using force or the threat of force against other countries, and to refuse help to any country that opposes UN actions.
UN membership is open to any country willing to further the UN mission and abide by its rules. Each country, no matter how large or small, has an equal voice and vote. Each country is also expected to pay dues to support the UN. As of 2004 the UN had 191 members, including nearly every country in the world.
The UN’s influence in world affairs has fluctuated over the years, but the organization gained new prominence beginning in the 1990s. It was awarded the Nobel Peace Prize in 2001. Still, the UN faces constant challenges. It must continually secure the cooperation of its member nations because the organization has little independent power or authority. But getting that support is noi always easy. Many nations are reluctant to defer their own authority and follow the dictates of the UN."4. Why does the UN face constant challenges?

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 biologist’s role in society as well as his moral and ethical responsibility in the discovery and development of new ideas has led to a reassessment of his social and scientific value systems. A scientist can no longer ignore the consequences of his discoveries; he is as concerned with the possible misuses of his findings as he is with the basic research in which he is involved. This emerging social and political role of the biologist and all other scientists requires a weighing of values that cannot be done with the accuracy or the objectivity of a laboratory balance. As a member of society, it is necessary for a biologist now to redefine his social obligations and his functions, particularly in the realm of making judgments about such ethical problems as man's control of his environment or his manipulation of genes to direct further evolutionary development.
As a result of recent discoveries concerning hereditary mechanisms, genetic engineering, by which human traits are made to order, may soon be a reality. As desirable as it may seem to be, such an accomplishment would entail many value judgments. Who would decide, for example, which traits should be selected for change? In cases of genetic deficiencies and disease, the desirability of the change is obvious, but the possibilities for social misuse are so numerous that they may far outweigh the benefits.
Probably the greatest biological problem of the future, as it is of the present, will be to find ways to curb environmental pollution without interfering with man's constant effort to improve the quality of his life.The pronoun "it" in paragraph 2 refers to________.

AN UNWELCOME GUEST
Of the one in seven people in the UK who claim to have seen a ghost, the majority are women. This may be because women have far more association with the spirit world. Women trust their emotions and are generally better able than men to cope with the unexpected.
Housewife Fiona Blair describes herself as very practical and down-to-earth, and never believed in the idea that a house could be haunted. That all changed when she and her family moved into a manor house in the Midlands. Although the surveyor reckoned that the house required a lot of attention and was somewhat damp, they thought it was stunning. They could just afford it and it would be a good investment, so they took the plunge and decided to buy it.
Nonetheless, right from the start, Fiona had a strange sense that they were not alone in the house. One of her teenage daughters had left a towel over the back of a chair in the kitchen. Fiona was in the garden, and when she returned to the house, the towel was over the kitchen table like a tablecloth. On other occasions the family would find that objects such as glasses and vases had been turned upside-down.
This was only the start of the peculiar happenings. A particularly strange incident happened on Fiona's birthday. Fiona's husband, Mark, came home from work and went into the living room. He immediately came rushing out to ask who had bought her the beautiful flowers - but nobody had given Fiona flowers and her daughters had not put the flowers there. It remained a mystery how they had miraculously appeared.
Fiona was curious and decided to find out about the history of the house. What she discovered was rather alarming. Apparently a young girl, servant to a previous generation of owners, had been found dead in peculiar circumstances in the attic. Fiona and her family inevitably began to feel claustrophobic and trapped in the house, and eventually decided that they would have to move.
Unfortunately, things were not as simple as that. Each time they attempted to show the house to potential buyers, Fiona would of course ensure beforehand that everything was neat and tidy in order to make a good impression. But by the time anyone arrived, the entire house would be in a complete mess, and visitors complained of an unpleasant atmosphere. Eventually, after many months, an American couple viewed the house, and decided it had a certain attraction. For some reason, the ghost did not play its usual tricks, and Fiona was able to sell what had been her dream home.
Now living in a spacious modern apartment in London, Fiona wants to forget it all and move on with her life. 'At one point I thought I might be going out of my mind, it was all so frightening. We can almost laugh about it all now, but I hope we never experience anything like that again.What did the ghost do when they decided to sell the house?

The brain of the average human weighs approximately 1.4 kilograms and consists of three main parts: the cerebrum, the cerebellum, and the brain stem. The cerebrum is by far the largest of the three parts, taking up 85% of the brain by weight. The outside layer of the cerebrum, the cerebral cortex, is a grooved and bumpy surface covering the nerve cells beneath. The various sections of the cerebrum are the sensory cortex, which is responsible for receiving and decoding sensory messages from throughout the body: the motor cortex, which sends action instructions to the skeletal muscles: and the association cortex, which receives, monitor and processes information. It is in the association cortex that the processes that allow humans to think take place.

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.
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 web surfers. 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 personal name. What can be inferred from the passage?

Read the passage and choose the correct answer:
For 70 years, UNICEF has been working on the ground in 190 countries and territories to promote children’s survival, protection and development. The world’s largest provider of vaccines for developing countries, UNICEF supports child health and nutrition, good water and sanitation, quality basic education for all boys and girls, and the protection of children from violence, exploitation, and AIDS. UNICEF is the driving force that helps build a world where the rights of every child are realized. As a global authority UNICEF is able to influence decision makers at the global level and turn the most innovative ideas into reality.
In all of its work, UNICEF takes a life-cycle based approach, recognizing the particular importance of early childhood development and adolescence. UNICEF programmes focus on the most disadvantaged children, including those living in fragile contexts, those with disabilities, those who are affected by rapid urbanization and those affected by environmental degradation.
UNICEF was created with a distinct purpose in mind: to work with others to overcome the obstacles that poverty, violence, disease and discrimination place in a child’s path. We advocate for measures to give children the best start in life, because proper care at the youngest age forms the strongest foundation for a person’s future.
We promote girls’ education – ensuring that they complete primary education as a minimum – because it benefits all children, both girls and boys. Girls who are educated grow up to become better thinkers, better citizens, and better parents to their own children. We act so that all children are immunized against common childhood diseases, and are well nourished: no child should suffer or die from a preventable illness. We work to prevent the spread of HIV/AIDS among young people because it is right to keep them from harm and enable them to protect others. We help children and families affected by HIV/AIDS to live their lives with dignity.
Boy’s education is promoted in the program of UNICEF

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 Science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.
After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists’ predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.
Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves arc not science. As the mathematician Jules Henri Poincare said: "Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house."
Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses. In a way, any hypothesis is a leap into the unknown. It extends the scientist's thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories.
According to the second paragraph, a useful theory is one that helps scientists to _______.

Read the passage below and choose one correct answer for each question.
Orbis is an organisation which helps blind people everywhere. It has built an eye hospital inside an aeroplane and flown it all over the world with an international medical team. Samantha Graham, a fourteen-year-old schoolgirl from England, went with the plane to Mongolia. Samantha tells the story of Eukhtuul, a young Mongolian girl. 'Last year, when Eukhtuul was walking home from school, she was attacked by boys with sticks and her eyes were badly damaged. Dr Duffey, an Orbis doctor, said that without an operation she would never see again. I thought about all the everyday things I do that she couldn't, things like reading schoolbooks, watching television, seeing friends, and I realised how lucky I am.' 'The Orbis team agreed to operate on Eukhtuul and I was allowed to watch, together with some Mongolian medical students. I prayed the operation would be successful. The next day I waited nervously with Eukhtuul while Dr Duffey removed her bandages. "In six months your sight ·will be back to normal, he said. Eukhtuul smiled, her mother cried, and I had to wipe away some tears, too!" "Now Eukhtuul wants to study hard to become a doctor. Her whole future has changed; thanks to a simple operation. We should all think more about how much our sight means to us."
After meeting Eukhtuul, Samantha felt __________.

It is difficult to write rules that tell exactly when we should apologize, but it is not difficult to learn how. If we have done something to hurt someone’s feeling or if we have been impolite or rude, we should apologize. An apology indicates that we realize we have made a mistake, and we are sorry for it. It is a way of expressing our regret for something. When we apologize, we admit our wrongdoing, usually offer a reason for it, and express regret.
The simplest way to apologize is to say “I’m sorry”, but often that is not enough. Let’s take a common situation. Mario is late for class and enters the classroom, interrupting the teacher in the middle of the class. What does he do? The most polite action is usually to take a seat as quietly as possible and apologize later. But if the teacher stops and waits for him to say something, he could apologize simply “I’m sorry I’m late”, ask permission to take his seat, and sit down. Naturally, more than this, a reason for the tardiness, is needed, but this is not the time or the place for it because he has already caused one interruption and doesn’t need to make it any longer or worse than it already is.We should apologize _____________

People used to know more or less how their children would live. Now things are changing so quickly that they don’t even know what their own lives will be like in a few years’ time. What follows is not science fiction. It is how experts see the future. You are daydreaming behind the steering wheel; is it too dangerous? No! That’s no problem because you have it on automatic pilot, and with its hi – tech computers and cameras, your car “know” how to get you home safe and sound. What is for lunch? In the old days you used to stop off to buy a hamburger or a pizza. Now you use your diagnostic machine to find out which foods your body needs. If your body needs more vegetables and less fat, your food – preparation machine makes you a salad.
After lunch, you go down the hall to your home office. Here you have everything you need to do your work. Thanks to your information screen and your latest generation computer, you needn’t go to the office anymore. The information screen shows an urgent message from a co-worker in Brazil. You can instantly send back a reply to him and go on to deal with other matters.Which of the following is NOT true about life in the future?

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.
Although speech is the most advanced form of communication, there are many ways of communicating without using speech. Signals, signs, symbols, and gestures may be found in every known culture. The basic function of signal is to impinge upon the environment in such a way that it attracts attention, as, for example, the dots and dashes of a telegraph circuit. Coded to refer to speech, the potential for communication is very great. Less adaptable to the codification of words, signs also contain meaning in and of themselves. A stop sign or a barber pole conveys meaning quickly and conveniently.
Symbols are more difficult to describe than either signals or signs because of their intricate relationship with the receiver’s cultural perceptions. In some cultures, applauding in a theater provides performers with an auditory symbol of approval. Gestures such as waving and handshaking also communicate certain cultural messages.
Although signals, signs, symbols, and gestures are very useful, they do have a major disadvantage in communication. They usually do not allow ideas to be shared without the sender being directly adjacent to the receiver. Without an exchange of ideas, interaction comes to a halt. As a result, means of communication intended to be used for long distances and extended periods must be based upon speech. To radio, television, and the telephone, one must add fax, paging systems, electronic mail, and the Internet, and no one doubts but that there are more means of communication on the horizon.
It may be concluded from this passage that ____________.
