     Many of us worry about the effects of television on family life. We think that we spend too much time watching television and that it takes us away from more important activities, such as reading, exercising and talking to family and friends. But is this really true? 
      Studies have shown that people in the United States do spend a lot of time in front of their television sets. About 98% of American homes have at least one TV set, and in the average home the TV is on more than six hours a day. But how much attention do people actually pay to the programs? And do people who watch TV really spend less time on other free-time activities? Recently some researchers in New York City tried to find the answers to these questions by conducting a telephone survey. They phoned more than a thousand people all over the United States and asked them questions about how they spend their free time.
      No one was surprised to find out that watching TV is the most popular free-time activity in the United States. More than 70% of those asked said that they watch TV every day or almost every day. The second most popular activity that they mentioned was reading the newspaper. Listening to music at home was third, talking on the phone to friends and relatives was fourth and doing some form of exercise was fifth. 
      But the researchers discovered an interesting fact about Americans' TV habits. According to this survey, although most people turn the TV on every day, they do not actually watch it very much. Six out of ten people said that when the TV is on, they seldom pay attention to it. During a typical television program, they may eat dinner, do housework, read a newspaper or magazine, talk to their children or even read to them. The TV may be on, but it is just background music.
      The researchers therefore concluded that television does not take Americans away from more important activities. It doesn't keep them from doing other free-time activities. In fact, when they compared people who frequently watch TV and those who seldom watch TV, they found that there were no great differences in their other activities. The frequent watchers read to their children and talk to their families just as much as the others.

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.

   Orchids are unique in having the most highly developed of all blossoms, in which the usual male and female reproductive organs are fused in a single structure called the column. The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically marked as an unmistakable landing strip to attract the specific insect the orchid has chosen as its pollinator. To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times.

   Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities. At the same time they have made themselves irresistible to collectors.

    In the Native American Navajo nation which sprawls across four states in the American south-west, the native language is dying. Most of its speakers are middle-age or elderly. Although many students take classes in Navajo, the schools are run in English. Street sign, supermarket goods and even their own newspaper are all in English. Not surprisingly, linguists doubt that any native speakers of Navajo will remain in a hundred years' time.
    Navajo is far from alone. Half the world's 6,800 languages are likely to vanish within two generations - that's one language lost every ten days. Never before has the planet's linguistic diversity shrunk at such a pace. Isolation breeds linguistic diversity as a result, the world is peppered with languages spoken by only a few people. Only 250 languages have more than a million speakers, and at least 3,000 have fewer than 2,500. It is not necessarily these small languages that are about to disappear. Navajo is considered endangered despite having 150,000 speakers. What makes a language endangered is not that the number of speakers, but how old they are. If it is spoken by children it is relatively safe. The critically endangered languages are those that are only spoken by the elderly, according to Michael Krauss, director of the Alaska Native Language Center, in Fairbanks.
    Why do people reject the language of their parent? It begins with a crisis of confidence, when a small community finds itself alongside a larger, wealthier society, says Nicholas Ostler of Britain's Foundation for Endangered Languages, in Bath. “People lose faith in their culture” he says. "When the next generation reaches their teens, they might not want to be induced into the old tradition.” The change is not always voluntary. Quite often, governments try to kill off a minority language by banning its use in public or discouraging its use in school, all to promote national unity. The former US policy of running Indian reservation in English, for example, effectively put languages such as Navajo on the danger list. But Salikoko Mufwene, who chairs the Linguistics Department at the University of Chicago, argues that the deadliest weapon is not government policy but economic globalisation. "Native Americans have not lost pride in their language, but they have had to adapt to socio-economic pressures" he says. “They cannot refuse to speak English if most commercial activity is in English."
    However, a growing interest in cultural identity may prevent the direct predictions from coming true. ‘The key to fostering diversity is for people to learn their ancestral tongue, as well as the dominant language' says Doug Whalen, founder and president of the Endangered Language Fund in New Haven, Connecticut. “Most of these will live without a large degree of bilingualism” he says.

Who thinks that a change of language may mean a loss of traditional culture?

In terms of sheer size, the Antarctic Desert is the largest desert on Earth, measuring a total of 13.8 million square kilometers. Antarctica is the coldest, windiest, and most isolated continent on Earth, and is considered a desert because its annual precipitation can be less than 51 mm in the interior.
 It’s covered by a permanent ice sheet that contains 90% of the Earth’s fresh water. Only 2% of the continent isn’t covered by ice, and this land is strictly along the coasts, where all the life that is associated with the land mass (i.e. penguins, seals and various species of birds) reside. The other 98% of Antarctica is covered by ice which averages 1.6 km in thickness.
There are no permanent human residents, but anywhere from 1,000 to 5,000 researchers inhabit the research stations scattered across the continent – the largest being McMurdo Station, located on the tip of Ross Island. Beyond a limited range of mammals, only certain cold-adapted species of mites, algaes, and tundra vegetation can survive there.

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.
There are many theories of aging, but virtually all fall into the category of hypotheses with a minimum of supporting evidence. One viewpoint is that aging occurs as the body's organ systems become less efficient. Thus failures in the immune system, hormonal system, and nervous system could all produce characteristics that we associate with aging. Following a different vein, many current researchers are looking for evidence at the cellular and sub cellular level. It has been shown that cells such as human fibroblasts (generalized tissue cells) grown in culture divide only a limited number of times and then die. Only cancer cells seem immortal in this respect. Fibroblast cells from an embryo divide more times than those taken from an adult. Thus some researchers believe that aging occurs at the cellular level and is part of the cell's genetic makeup. Any event that disturbs the cell's genetic machinery such as mutation, damaging chemicals in the cell's environment, or loss of genetic material, could cause cells to lose their ability to divide and thus bring on aging. Other theories of aging look at different processes. 
Chronological aging refers to the passage of time since birth and is usually measured in years. While chronological age can be useful in estimating the average status of a large group of people, it is a poor indicator of an individual person's status because there is a tremendous amount of variation from one individual to the next in regard to the rate at which biological age changes occur. For example, on the average, aging results in people losing much of their ability to perform strenuous activities, yet some elderly individuals are excellent marathon runners.
Another type of aging is cosmetic aging, which consists of changes in outward appearance with advancing age. This includes changes in the body and changes in other aspects of a person's appearance, such as the style of hair and clothing, the type of eyeglasses, and the use of a hearing aid. Like chronological aging, it is frequently used to estimate the degree to which other types of aging have occurred. However, it is an inaccurate indicator for either purpose because of variation among individuals and because a person's appearance is affected by many factors that are not part of aging, including illness, poor nutrition, and exposure to sunlight.

  As explained in this passage, the theory of aging which examines the cellular level would NOT assign which of the following as a cause of aging?

 Choose the word or phrase among A, B, C or D that best fits the blank space in the following passage:

The Alaska pipeline starts at the frozen edge of the Arctic Ocean. It stretches southward acros the largest and northernmost state in the United States, ending at a remote ice-free seaport village nearly 800 miles from where it begins. It is massive in size and extremely complicated to operate. The steel pipe crosses windswept plains and endless miles of delicate tundra that tops the frozen group. It weaves through crooked canyons, climbs sheer mountains, plunges over rocky crags, make it way through thick forests, and passes over or under hundreds of rivers and streams. The pipe is 4 feet in diameter and up to 2 million barrels or 84 million gallons of crude oil can be pumped through it daily. Resting on H-shaped steel racks called “bents,” long sections of the pipeline follow a zigzag course high above the frozen earth. Other long sections drop out of sight beneath spongy or rocky ground and return to the surface later on. The pattern of the pipeline’s up-and-down route is determined by the often harsh demands of the arctic and subarctic climate, the tortuous lay of the land, and the varied compositions of soil, rock, or permafrost permanently frozen ground. A little more than half of the pipeline is elevated above the ground. The remainder is buried anywhere from 3 to 12 feet, depending largely upon the type of terrain and the properties of the soil. One of the largest in the world, the pipeline cost approximately $8 billion and is by far the bigges and most expensive construction project ever undertaken by private industry. In fact, no single busines could raise that much money, so 8 major oil companies formed a consortium in order to share the cost. Each company controlled oil rights to particular shares of land in the oil fields and paid into the pipeline –construction fund according to the size of its holdings. Today, despite enormous problems o climate, supply shortages, equipment breakdowns, labor disagreements, treacherous terrain, a certain amount of mismanagement, and even theft, the Alaska pipeline has been completes and is operating.

the author mentions all of the following as important in determining the pipeline’s route EXCEPT the _________.

Long gone but not forgotten are those carefree student days of shared showers, derelict rental properties and parties where the booze always ran out before midnight. Being a student was quite a privilege in the good old days when local authorities and the government footed the bill and there was almost certainly a job at the end of it.
In the early 1960s, only 4% of school leavers went to university, rising to around 14% by the end of the 1970s. Nowadays, more than 40% of young people start undergraduate degrees – but it comes at a cost. Today’s students leave with debts of £40,000 and upwards to pay back over their working lives.
So how has the student experience changed over the years? Parents looking back on their university lives are amazed at the luxuries their sons and daughters enjoy, such as en suite bathrooms, flatscreen TVs and leather sofas. Student accommodation has improved but rents have soared and take up a bigger whack of the living cost loans, leaving today’s undergraduates little better off than their parents.
They still party and have a good time, but students are working harder and more consistently, their parents believe. Partly, it is the move away from “big bang” finals to continuous assessment, they say, but also the pressure to get that all-important 2:1 or above degree classification. One-third of students were awarded firsts or 2:1s in 1970. Last year it was over two-thirds: 70%.
Today’s students are more career-orientated and under pressure to take on extracurricular activities, more responsibilities and work experience to compete in the graduate jobs market. Meeting people, making friends for life and discovering new interests: these are the things that have not changed for students who are following the same route to independence as their parents.

The following adjectives are true about today’s students in comparison with their parents, EXCEPT _________.
