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 phrase “footed the bill” in the first paragraph mostly means ______________.

"Desert is the term applied to regions of the earth that are characterized by less than 254 mm (10. inches) of annual rainfall, an evaporation rate that exceeds precipitation, and, in most cases, a high average temperature. Because of a lack of moisture in the soil and low humidity in the atmosphere, most of the sunlight penetrates to the ground. Daytime temperatures can reach 55° c (131° F) in the shade. At night the desert floor radiates heat back to the atmosphere, and the temperature can drop to near freezing. Deserts are caused by a combination of climate patterns and geological features.
 Because so little water moves through the desert soil to carry nutrients away, desert soils are naturally fertile. Crops are grown on desert lands with water provided by irrigation from rivers or wells. Such transformations of deserts are not without problems. Evaporation of the irrigation water results in the accumulation of salt on the surface soil, eventually rendering it useless for further crop production. By tapping reservoirs of fossil water deep beneath the desert, humans are, in effect, mining water. Once this water is gone, it is irreplaceable. Burning and overgrazing of semiarid lands on the periphery of deserts can irreversibly damage the plants that concentrate moisture and hold the soil together, thus enabling deserts to encroach on arable land. This encroachment, a serious world problem, is called desertification. A 1984 report of a desertification study made for the United Nations stated that 35 percent of the earth’s land surface was at least threatened by such processes."

Are you interested in seeing the beautiful fall foliage of New England but tired of traffic jams and overbooked hotels? Then this year forget the crowds in New England and see the beautiful colors of autumn in the Catskills.
These rugged mountains in New York State, just 90 miles northwest of New York City, are famous for the legendary tales of Rip Van Winkle, and more recently for the summer hotels that sprang up in the region during the 1940s, 1950s, and 1960s. Families trying to escape the heat of New York City found the Catskills to be the perfect place to stay for a month or so each summer. By the late 1950s there were over 500 resorts and hotels offering nighttime entertainment as well as all kinds of outdoor activities. Famous comedians like Jackie Gleason, Joan Rivers, and Sid Caesar all got their start touring the hotel clubs here. Since the introduction of air-conditioning and cheaper air travel, however, families have stopped coming to the Catskills in such large numbers, choosing instead more distant locations at different times of the year. Many of the Catskill hotels closed in the 1970s, but some remain and have expanded and changed their facilities to meet the needs of today's visitors.
Currently, there are many activities available to the traveler besides witnessing the changing colors of the leaves. There is an all-organic sheep farm where visitors can see how a traditional sheep farm operates. There are also hundreds of miles of scenic drives in the area. Route 42, for instance, is an excellent site for spotting bald eagles. For more information on vacations in the Catskills, call the Office of Public Information.

It is not easy to choose a career today. Hundreds of students are leaving schools and universities every year  to  seek  employment  in  the  various  professions,  though  employment  opportunities  are  not  increasing proportionately. As a result, there is a lot of unemployment.   

 The inability of the various professions to absorb all those seeking employment makes the choice of a career more difficult. Before one leaves school or university, one has many plans, confident that choosing a career will not be difficult. But when, the time comes to choose a career, one finds that there are others with better qualifications waiting to enter the same profession.  Disillusioned, one then looks for  any  kind of employment.  In this way,  many  who  wanted  to  become  police  inspectors or field  assistants  in  the  rubber estates in this country,  become  teachers  instead,  and many who  wanted  to  become  teachers,  have  become shop assistants. The lack of institutions where people could acquire the skills necessary for a particular career makes the choice of a career even more difficult.

Accustomed though we are to speaking of the films made before 1927 as "silent," the film has never been, in the full sense of the word, silent. From the very beginning, music was regarded as an indispensable accompaniment; when the Limeira films were shown at the first public film exhibition in the United States in February 1896, they were accompanied by piano improvisations on popular tunes. At first, the music played bore no special relationship to the films; an accompaniment of any kind was sufficient. Within a very short time, however, the incongruity of playing lively music to a solemn film became apparent, and film pianists began to take some care in matching their pieces to the mood of the film. As movie theaters grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain cases, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program rested entirely in the hands of the conductor or leader of the orchestra, and very often the principal qualification for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before they were to be shown (if, indeed, the conductor was lucky enough to see them then), the musical arrangement was normally improvised in the greatest hurry. To help meet this difficulty, film distributing companies started the practice of publishing suggestions for musical accompaniments. In 1909, for example, the Edison Company began issuing with their films such indications of mood as "pleasant," "sad," "lively." The suggestions became more explicit, and so emerged the musical cue sheet containing indications of mood, the titles of suitable pieces of music, and precise directions to show where one piece led into the next. Certain films had music especially composed for them. The most famous of these early special scores was that composed and arranged for D.W. Griffith's film “Birth of a Nation”, which was released in 1915.

What can be inferred from the passage about the majority of films made after 1927?

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often

Polar bears are in danger of dying out. Unlike some other endangered animals, it's not hunters that are the problem, it's climate change. Since 1979, the ice cap at the Arctic Circle where the polar bears has reduced in size (21) about 30 percent. The temperature in the Arctic has slowly been rising and this is (22) the sea ice to melt, endangering the polar bears' home. The polar bears' main sources of food are the different types of seals found in the Arctic. They catch them by waiting next to the air holes seals have made in the ice. (23) the bears are very strong swimmers, they could never catch seals in water. This means that the bears really do rely on the ice to hunt.
Polar bears also need sea ice to travel. They can cover a huge territory and often swim from one part of the ice to another. They have been (24) to swim up to 100 km, but when there is less ice, they may have to swim further and this can (25) fatal to the bears. A number of bears have drown in the last few years and scientists believe that it is because they were not able to reach more ice before they became too tired and couldn't swim any further.

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.

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.

     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.
