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:
Most people need some preparation before they are ready for the workforce, and planning should begin long before it is time to start a career.
Many high school students don't yet know what they want to do. High school is a great time to start thinking about careers. Settling on just one occupation in high school isn't necessary, but they should know how to explore careers and put time into investigating them and learning about their skills and interests.
Understanding what you enjoy what you are good at is the first step in exploring careers. It is important to think about what you like to do because work will eventually be a big part of your life. Once you have thought about the subjects and activities you like best, the next step is to look for careers that put those interests to use. If you love sports, for example, you might consider a career as a gym teacher, or coach.
Another approach to identifying potential career interests is to consider local employers and the types of jobs they have. There are many jobs in manufacturing and healthcare near the high school. Talking directly to workers can help you get information about what they do. If you don't know workers in occupations that interest you, ask people such as your parents, friends, or teacher for their contacts.
If job shadowing give you taste of what an occupation is like, imagine how helpful getting experience could be. Students can begin getting career-related experiences in high school through internships, employment, and other activities. Completing an internship is an excellent way to get experience. Internships are temporary, supervised assignments designed to give student practical job training.The word “them” in paragraph 2 refers 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:
We first learn about loving and caring relationships from our families. Family is defined as a domestic group of people with some degree of kinship - whether through blood, marriage, or adoption. Ideally, each child is nurtured, respected, and grows up to care for others and develop strong and healthy relationships. This does not mean that it is always easy to make and keep friends; it just means that we share the goal of having strong relationships.
"Family" includes your siblings and parents, as well as relatives who you may not interact with every day, such as your cousins, aunts, uncles, grandparents, and stepparents.
These are probably the people you are closest to and with whom you spend the most time. Having healthy relationships with your family members is both important and difficult.
Families in the 21st century come in all shapes and sizes: traditional, single parent, blended (more than one family together in the same house], and gay and lesbian parents -just to name a few. No matter the "type" of family you have, there are going to be highs and lows - good times and bad. Many times, however, families become blocked in their relationships by hurt, anger, mistrust, and confusion. These are natural and normal, and few families do not have at least a few experiences with them. The worst time for most families, is during a divorce. By making a few simple changes in the way we look at the world and deal with other people, it is possible to create happier, more stable relationships. Families need to be units of mutual caring and support; they can be sources of lifelong strength for all individuals.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:
In the United States in the early 1800's, individual state governments had more effect on the economy than did the federal government. States chartered manufacturing, banking, mining, and transportation firms and participated in the construction of various internal improvements such as canals, turnpikes, and railroads. The states encouraged internal improvements in two distinct ways; first, by actually establishing state companies to build such improvement; second, by providing part of the capital for mixed public-private companies setting out to make a profit.
In the early nineteenth century, state governments also engaged in a surprisingly large amount of direct regulatory activity, including extensive licensing and inspection programs. Licensing targets reflected both similarities in and differences between the economy of the nineteenth century and that of today: in the nineteenth century, state regulation through licensing fell especially on peddlers, innkeepers, and retail merchants of various kinds. The perishable commodities of trade generally came under state inspection, and such important frontier staples as lumber and gunpowder were also subject to state control. Finally, state governments experimented with direct labor and business regulation designed to help the individual laborer or consumer, including setting maximum limits on hours of work and restrictions on price-fixing by businesses.
Although the states dominated economic activity during this period, the federal government was not inactive. Its goals were the facilitation of western settlement and the development of native industries. Toward these ends the federal government pursued several courses of action. It established a national bank to stabilize banking activities in the country and, in part, to provide a supply of relatively easy money to the frontier, where it was greatly needed for settlement. It permitted access to public western lands on increasingly easy terms, culminating in the Homestead Act of 1862, by which title to land could be claimed on the basis of residence alone. Finally, it set up a system of tariffs that was basically protectionist in effect, although maneuvering for position by various regional interests produced frequent changes in tariff rates throughout the nineteenth century.The word “ends” in line 20 is closest in meaning to

Mark Zuckerberg was born in 1984, in New York, into a prosperous, professional family. He developed an interest in computers at an early age and when he was twelve, he created a messaging program which he named "Zucknet". His dentist father used it in his surgery so that his receptionist could inform him of the arrival of a patient without yelling across the room. Together with his friends, Mark spent much of his spare time as a boy designing and making computer games just for fun.
In 2002, Mark enrolled at Harvard University. By his second year at the institution, he had acquired a reputation on the campus as a developer of software. It was at that time he invented "Facemash" which compared pictures of female students and allowed users to vote on which one was the most attractive. The program became very popular on campus, but was later shut down by the university authorities who deemed it 'inappropriate'.
Based on the buzz of "Facemash", three of Mark's fellow students, Divya Narendra, and twins, Cameron and Tyler Winklevoss, asked him to work with them on an idea for a social networking site called "Harvard Connection". This site was designed to use information from Harvard's student networks to create a dating site for the university's elite. Mark was initially enthusiastic about the complex project but boredom soon set in
and he backed out of it to work on his own social networking site. He created a site that allowed users to produce their own profiles, upload photos, and communicate with other people beyond the confines of the university. He called the site "Facebook" and he operated from one small college room until June 2004 when he finally abandoned his studies to devote himself fully to Facebook and moved the company to California. By the end of 2004, Facebook had one million users and Mark was climbing high.The word "This site" in paragraph 3 refers 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.
Volunteering has been acknowledged as part of the wider health policy, with the NHS five-year plan identifying a need to encourage community volunteering. It also has an important role to play in tackling social exclusion, through projects such as lunch clubs for older people, assisted gardening schemes, or young play leaders.
Volunteering can help to provide people with ways out of poverty, by giving them new skills, confidence and aid social integration. This is of particular value to those who are most excluded from the labour market, such as recent migrants or people with disabilities. But while the benefits of volunteering are clear, there is worrying evidence that the people who could benefit most from giving their time are precisely those least likely to be involved.
There are many reasons for people not to volunteer. For older people, the barriers can include poor health, poverty, lack of skills, poor transport links, or having caring responsibilities, such as looking after grandchildren. Younger people can be deterred by feeling they don’t have the time to volunteer, or not knowing anyone else who volunteers. Many of them also think volunteering is just for older people with time on their hands. Volunteering has an image problem – particularly with men and younger people.
More should be done to promote the value of volunteering to the particular needs of different groups. There is evidence on why people choose to volunteer, and we need to make better use of that information. For instance, a recent survey showed that 95% of young people, aged 13-24, hoped to develop new skills through volunteering, compared to just 32% of volunteers aged over 55. Almost three quarters of young people were keen to gain qualifications through volunteering compared to just 13% of those over 55. Over three quarters of disabled volunteers were keen to develop new skills and nearly two thirds hoped to improve their health and wellbeing through volunteering.What is the main idea of the passage?

Choose the option that best completes each of the following sentences.
Computer programmer David Jones earns £35,000 a year designing new computer games, yet he cannot find a bank prepared to let him have a cheque card. Instead, he has been told to wait another two years, until he is 18.
The 16-year-old works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David's firm releases two new games for the expanding home computer market each month.
But David's biggest headache is what to do with his money.
Despite his salary, earned by inventing new programs within tight schedules, with bonus payments and profit-sharing, he cannot drive a car, take out a mortgage, or obtain credit cards.
He lives with his parents in their council house in Liverpool, where his father is a bus driver. His company has to pay £150 a month in taxi fares to get him the five miles to work and back every day because David cannot drive.
David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. "I got the job because the people who run the firm knew 1 had already written some programs," he said.
"I suppose £35,000 sounds a lot but actually that's being pessimistic. I hope it will come to more than that this year." He spends some of his money on records and clothes, and gives his mother £20 a week. But most his spare time is spent working.
"Unfortunately, computing was not part of our studies at school," he said. "But 1 had been studying it in books and 'magazines for four years in my spare time. 1 knew what 1 wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway."
David added: "I would like to earn a million and 1 suppose early retirement is a possibility. You never know when the market might disappear."
David's greatest problem is ………….

There are a number of natural disasters that can strike across the globe. Two that are frequently linked to one another are earthquakes and tsunamis. Both of them can cause a great amount of devastation when they hit. However, tsunamis are the direct result of earthquakes and cannot happen without them.
The Earth has three main parts. They are the crust, the mantle, and the core. The crust is the outer layer of the Earth. It is not a single piece of land. Instead, it is comprised of a number of plates.
There are a few enormous plates and many smaller ones. These plates essentially rest upon the mantle, which is fluid. As a result, the plates are in constant – yet slow – motion. The plates may move away from or toward other plates. In some cases, they collide violently with the plates adjoining them. The movement of the plates causes tension in the rock. Over a long time, this tension may build up. When it is released, an earthquake happens.Tens of thousands of earthquakes happen every year. The vast majority are so small that only scientific instruments can perceive them. Others are powerful enough that people can feel them, yet they cause little harm or damage. More powerful earthquakes, however, can cause buildings, bridges, and other structures to collapse. They may additionally injure and skill thousands of people and might even cause the land to change it appearance.
Since most of the Earth’s surface is water, numerous earthquakes happen beneath the planet’s oceans. Underwater earthquakes cause the seafloor to move. This results in the displacement of water in the ocean. When this occurs, a tsunami may form. This is a wave that forms on the surface and moves in all directions from the place where the earthquake happened. A tsunami moves extremely quickly and can travel thousnads of kilometres. As it approaches land, the water near the coast gets sucked out to sea. This causes the tsunamis to increase in height.
Minutes later, the tsunami arrives. A large tsunami – one more than ten meters in height – can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill large numbers of peopleThe word “adjoining” in bold in paragraph 2 is closest in meaning to ..............

The Singapore Science Centre is located on a six-hectare site in Jurong. At the centre, we can discover the wonders of science and technology in a fun way. Clap your hands and colorful bulbs will light up. Start a wheel spinning and it will set off a fan churning. It is a place to answer our curiosity and capture our imagination.
The centre features over four hundred exhibits covering topics like solar radiation, communication, electronics, mathematics, nuclear energy and evolution. It aims to arouse interest in science and technology among us and the general publiC. The centre is the first science one to be established in South East AsiA. It was opened in 1977 and it now receives an average of one thousand, two hundred visitors a day. The exhibits can be found in four exhibition galleries. They are the Lobby, Physical Sciences, Life Sciences and Aviation. These exhibits are renewed annually so as to encourage visitors to make return visits to the centre.
Instead of the usual “Hands off’ notices found in exhibition halls, visitors are invited to touch and feel the exhibits, push the buttons, turn the cranks or pedals. This is an interesting way to learn science even if you hate the subject. A Discovery Centre was built for children between the ages of three and twelve. This new exhibition gallery was completed in 1985. Lately this year a stone-age exhibit was built. It shows us about the animals and people which were extinct.What does “Hand off” in paragraph 3 means?

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 Trump campaign ran on bringing jobs back to American shores, although mechanization has been the biggest reason for manufacturing jobs’ disappearance. Similar losses have led to populist movements in several other countries. But instead of a pro-job growth future, economists across the board predict further losses as AI, robotics, and other technologies continue to be ushered in. What is up for debate is how quickly this is likely to occur.
Now, an expert at the Wharton School of Business at the University of Pennsylvania is ringing the alarm bells. According to Art Bilger, venture capitalist and board member at the business school, all the developed nations on earth will see job loss rates of up to 47% within the next 25 years, according to a recent Oxford study. “No government is prepared,” The Economist reports. These include blue and white collar jobs. So far, the loss has been restricted to the blue collar variety, particularly in manufacturing.
To combat “structural unemployment” and the terrible blow, it is bound to deal the American people, Bilger has formed a nonprofit called Working Nation, whose mission it is to warn the public and to help make plans to safeguard them from this worrisome trend. Not only is the entire concept of employment about to change in a dramatic fashion, the trend is irreversible. The venture capitalist called on corporations, academia, government, and nonprofits to cooperate in modernizing our workforce.
To be clear, mechanization has always cost us jobs. The mechanical loom, for instance, put weavers out of business. But it also created jobs. Mechanics had to keep the machines going, machinists had to make parts for them, and workers had to attend to them, and so on. A lot of times those in one profession could pivot to another. At the beginning of the 20th century, for instance, automobiles were putting blacksmiths out of business. Who needed horseshoes anymore? But they soon became mechanics. And who was better suited?
Not so with this new trend. Unemployment today is significant in most developed nations and it’s only going to get worse. By 2034, just a few decades, mid-level jobs will be by and large obsolete. So far the benefits have only gone to the ultra-wealthy, the top 1%. This coming technological revolution is set to wipe out what looks to be the entire middle class. Not only will computers be able to perform tasks more cheaply than people, they’ll be more efficient too.
Accountants, doctors, lawyers, teachers, bureaucrats, and financial analysts beware: your jobs are not safe. According to The Economist, computers will be able to analyze and compare reams of data to make financial decisions or medical ones. There will be less of a chance of fraud or misdiagnosis, and the process will be more efficient. Not only are these folks in trouble, such a trend is likely to freeze salaries for those who remain employed, while income gaps only increase in size. You can imagine what this will do to politics and social stability.What does the word “they” in paragraph 5 refer 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:
Atomic were once thought to be fundamental pieces of matter, but they are in turn made of smaller subatomic particles There are three major subatomic particles neutrons, protons, and electronic. Protons and neutrons can be broken into even smaller units, but these smaller units not occur naturally in nature and are thought to only be produced in manmade particle accelerators and perhaps in extreme stellar events like supernovas. The structure of an atom can best be described as a small solar system, with the neutrons at the center and the electrons circling them in various orbits, just as the planets circle the sun. In reality, the structure of an atom is far more complex, because the laws of physics are fundamentally different at the atomic level than at the level of the observable word. The true nature of atomic structure can only be expressed accurately through complex mathematical formulas. This explanation, however, is of little use to most average people.
Protons and neutrons have nearly equal mass and size, but protons carry a positive electrical charge, while neutrons carry no charge at all. Protons and neutrons are bound together by the strong nuclear force, one of the four basic forces in the universe. Protons and neutrons give atoms some of their most basic properties. Elements are defined by two numbers: their atomic number, which is equal to the number of protons they have, and their atomic weight, which is equal to total number of their neutrons and protons. In most lighter atoms, the number of neutrons and protons is equal, and the element is stable. In heavier atoms, however, there are more neutrons than protons, and the element is unstable, eventually losing neutrons through radioactive decay until a neutral state is reached.
Electrons are negatively charged particles. They are bound to their atoms through electromagnetic attraction. Opposite electrical charges attract one another, so the positive charge of the proton helps to keep the negatively charged electron in orbit around the nucleus of the atom. Electrons are different from neutrons in that they cannot be broken down into smaller particles. They are also far smaller and lighter than neutrons and protons. An electron is about one thousandth of the diameter of a proton and an even smaller fraction of its mass. Electrons circle the protons and neutrons at the center of the atom in orbits. These orbits are often called electron shells. The closer the orbit is to the center of the atom, the lower its energy is. There are seven electron shells, and each higher level can hold more electrons than the previous shell. Electrons naturally seek to occupy the lowest shell possible. So, if there is space in a lower shell, an electron will drop down to occupy that space. At temperatures higher than a few hundred degrees, electrons will gain energy and move to a higher shell, but only momentarily. When the electrons drop back down to their natural shell, they emit light. This is why fires and other very hot objects seem to glow.
Electrons are also primarily responsible for many of the chemical properties of atoms. Since electrons seek to occupy the lowest electron shell possible, they will move from one atom to another if there is a space available in a lower electron shell. For example, if there is an atom with an open space in its third shell, and it comes into contact with an atom with electrons in its fourth shell, the first atom will take one of these electrons to complete its third shell. When this happens, the two atoms will be chemically bonded to form a molecule. Furthermore, atoms sometimes lose electrons in collisions with other atoms. When this happens, the radio of protons and electrons in the atom changes, and therefore, the overall electrical charge of the atom changes as well. These atoms -

In the American colonies there was little money. England did not supply the colonies with coins and did not allow the colonies to make their own coins, except for the Massachusetts Bay Colony, which received permission for a short period in 1652 to make several kinds of silver coins. England wanted to keep money out of America as a means of controlling trade: America was forced to trade only with England if it did not have the money to buy products from other countries. The result during this pre-revolutionary period was that the colonists used various goods in place of money: beaver pelts, Indian wampum, and tobacco leaves were all commonly used substitutes for money. The colonists also made use of any foreign coins they could obtain. Dutch, Spanish, French, and English coins were all in use in the American colonies.
During the Revolutionary War, funds were needed to finance the world, so each of the individual states and the Continental Congress issued paper money. So much of this paper money was printed that by the end of the war, almost no one would accept it. As a result, trade in goods and the use of foreign coins still flourished during this period.
By the time the Revolutionary War had been won by the American colonists, the monetary system was in a state of total disarray. To remedy this situation, the new Constitution of the United States, approved in 1789, allowed Congress to issue money. The individual states could no longer have their own money supply. A few years later, the Coinage Act of 1792 made the dollar the official currency of the United States and put the country on a bimetallic standard. In this bimetallic system, both gold and silver were legal money, and the rate of exchange of silver to gold was fixed by the government at sixteen to one.The passage indicates that during the colonial period, money was

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:
Nature has always provided a stimulus for inventive minds. Early flying machines clearly were an attempt to emulate the freedom of birds. Architects and engineers have often consciously modeled buildings on forms found in nature. A more recent example of the inspiration given by nature is the invention of Velcro®. The inventor of this now common fastening device noticed that small burrs attached to his dog's coat grasped the hairs by means of tiny hooks. This led him to invent a synthetic fabric whose surfaces mimic the clasping properties of this natural seedpod.
Animals and plants have evolved solutions to the kinds of problems that often interest engineers and designers. Much current research in material science is concerned with actively examining the natural world, especially at the molecular level, for inspiration to develop materials with novel properties. This relatively new field of study is sometimes known as biomimetics, since it consciously attempts to mimic nature.
Researchers have investigated several interesting areas. For example, they have studied how the molecular structure of antler bone contributes to its amazing toughness, how the skin structure of a worm contributes to its ability to crawl, how the sea cucumber softens its skeleton and changes shape so that it can squeeze through tiny gaps in rocks, or what gives wood its high resistance to impact. These investigations have led to several breakthroughs in the development of composite materials with remarkable properties.
Predictions for future inventions that may be developed from these lines of research include so- called smart structures that design and repair themselves in a similar way to a variety of processes in the natural world. For example, engineers have envisaged bridges that would detect areas heavily stressed by vehicle movement or wind. The bridge structure would then automatically add or move material to the weak areas until the stress is reduced. The same principle might be used to repair damaged buildings. Other new materials that have been imagined are substances that would copy photosynthesis in green plants in order to create new energy sources. The potential impact of biomimetic research is so great that the twenty-first century may come to be known as the "Age of Materials."According to the passage, what do investigations in biomimetics suggest?

Most of the fastening devices used in clothing today, like the shoelace, the button, and the safely pin. have existed in some form in various cultures for thousands of years. But the zipper was the brainchild of one American inventor, namely Whitcomb Judson of Chicago. At the end of the 19th century. Judson was already a successful inventor, with a dozen patents to his credit for mechanical items such as improvements to motors and railroad braking system.
He then turned his mind to create a replacement for the lengthy shoelaces which were then used in both men’s and women's boots. On August 29th 1893, he won another patent, for what he called the case “locker”. Though the model was somewhat clumsy, and frequently jammed, it did work: in fact, Judson and his business associate Lewis Walker had sewn the device into their own boots. Although Judson displayed his clasp–locker at the World's Fair held in Chicago in 1893, the public largely ignored it. The company founded by Judson and Walker, Universal Fastener, despite further refinements, never really succeeded in marketing the device.
The earliest zip fasteners were being used in the clothing industry by 1905, but it was only in 1913, after a Swedish–American engineer, Gideon Sundbach, had remodeled Judson's fastener into a more streamlined and reliable form, that the zipper was a success. The US Army applied zippers to the clothing and equipment of the troops of World War I. By the late 1920s, zippers could be found in all kinds of clothing, footwear, and carrying cases; by the mid–1930s, zippers had even been embraced by the fashion industry.
The term “zipper" was coined as onomatopoeia (resembling the sound it makes) by B.F. Goodrich whose company started marketing rubber shoes featuring the fastener in 1923. Regrettably. Whitcomb Judson died in 1909, and never heard the term, or saw the success by which his invention would become popular.The word "refinements" in paragraph 2 is closest in meaning to .

It weighed about 10,000 tons, entered the atmosphere at a speed of 64,000 km/h and exploded over a city with a blast of 500 kilotons. But on 15 February 2013, we were lucky. The meteorite that showered pieces of rock over Chelyabinsk, Russia, was relatively small, at only about 17 metres wide. Although many people were injured by falling glass, the damage was nothing compared to what had happened in Siberia nearly one hundred years ago. Another relatively small object (approximately 50 metres in diameter) exploded in mid–air over a forest region, flattening about 80 million trees. If it had exploded over a city such as Moscow or London, millions of people would have been killed.
By a strange coincidence, the same day that the meteorite terrified the people of Chelyabinsk, another 50m–wide asteroid passed relatively close to Earth. Scientists were expecting that visit and know that the asteroid will return to fly close by us in 2046, but the Russian meteorite earlier in the day had been too small for anyone to spot.
Most scientists agree that comets and asteroids pose the biggest natural threat to human existence. It was probably a large asteroid or comet colliding with Earth which wiped out the dinosaurs about 65 million years ago. An enormous object, 10 to 16 km in diameter, struck the Yucatan region of Mexico with the force of 100 megatons. That is the equivalent of one Hiroshima bomb for every person alive on Earth today.
Many scientists, including the late Stephen Hawking, say that any comet or asteroid greater than 20 km in diameter that hits Earth will result in the complete destruction of complex life, including all animals and most plants. As we have seen, even a much smaller asteroid can cause great damage.
The Earth has been kept fairly safe for the last 65 million years by good fortune and the massive gravitational field of the planet Jupiter. Our cosmic guardian, with its stable circular orbit far from the sun, sweeps up and scatters away most of the dangerous comets and asteroids which might cross Earth’s orbit. After the Chelyabinsk meteorite, scientists are now monitoring potential hazards even more carefully but, as far as they know, there is no danger in the foreseeable future.AThe word “it” in paragraph 1 refers to .
