Read the following passage, then choose the correct answer to questions 31 - 35.
Smoking causes lung cancer, which is the number one cancer among men. Ninety percent of the people who get lung cancer die. Smoking is also the leading cause of mouth cancer, tongue cancer, and throat cancer. Many smokers have heart disease arid pneumonia. Smoking causes one million early deaths in the world every year.
Smokers not only harm themselves but also harm others. Smokers breathe smoke out into the air. They breathe it out on their children and their wives or husbands. Children whose parents smoke have more breathing and lung problems than other children. Women who are married to smokers are more likely to have lung cancer than those married to non- smokers.
We are all aware that smoking is bad. So why do people smoke?

Who are more likely to have lung cancer and lung problems?

The idea of life in outer space has been talked about for a long time. Some scientists say that life development on Earth was far too unlikely for it to have happened anywhere else. Things had to be perfect for us to make it on this planet. Other scientists say that space is too big. Stars and other planets are far too numerous for there to be no other life in the universe.
For many years, there have been reports of visitors from other planets. People all around the world have claimed to see alien spaceships or even aliens themselves. There have been glimpses of these so-called UFOs (unidentified flying objects) flying through the air and they have even been captured on video. Some Americans believe that the U.S. Army found an alien spaceship crashed in the desert and then lied to the press about it. Although these sightings may be true, scientists have not found significant evidence that aliens exist.
If you go out into the countryside on a clear night and look up, you can see thousands of stars. Those stars make up a tiny part of our unniverse. There are more stars, planets, and galaxies than we can count. Even the smartest scientists can’t even come close to defining how big space is. The number of possible stars and planets out there is bigger than our ability to count. If we are really on the only planet that can sustain life, then we are very special in a universe full of amazing things.

What can be inferred about finding aliens?

Water scarcity is fast becoming one of the major limiting factors in world crop production.  In many areas, poor agricultural practices have led to increasing desertification and the loss of formerly arable lands. Consequently, those plants species that are well adapted to survival in dry climates are being looked at for an answer in developing more efficient crops to grow on marginally arable lands.
Plants uses several mechanisms to ensure their survival in desert environments. Some involve purely mechanical and physical adaptations, such as the shape of the plant's surface, smaller leaf size, and extensive root systems. Some of the adaptations are related to chemical mechanisms. Many plants, such as cacti, have internal gums and mucilages which give them water-retaining properties. Another chemical mechanism is that of the epicuticular wax layer. This wax layer acts as an impervious cover to protect the plant. It prevents excessive loss of internal moisture. It also protects the plant from external aggression, which can come from inorganic agents such as gases, or organic agents which include bacteria ant plant pets.
Researchers have proposed that synthetic waxes with similar protective abilities could be prepared based on knowledge of desert plants. If successfully developed, such a compound could be used to greatly increase a plant's ability to maintain health in such adverse situations as inadequate water supply, limited fertilizers availability, attacked by pets, and poor storage after harvesting

Birds that feed in flocks commonly retire together into roosts. The reasons for roosting communally are not always obvious, but there are some likely benefits, In winter especially, it is important for birds to keep warm at night and conserve precious food reserves. One way to do this is to find a sheltered roost. Solitary roosters shelter in dense vegetation or enter a cavity- horned, larks dig holes In the ground and ptarmigan burrow into snow banks- but the effect of sheltering is magnified by several birds huddling together in the roost, as wrens, swifts, brown creepers, bluebirds, and anis do. Body contact reduces the surface area exposed to the cold air, so the birds keep each other warm. Two kinglets huddling together were found to reduce their heat losses by a quarter and three together saved a third of their heat.

The second possible benefit of communal roosts is that they act as "information centers". During the day, parties of birds will have spread out to forage over a very large area. When they return in the evening some will have fed well, but others may have found little to eat. Some investigators have observed that when the birds set out again next morning, those birds that did not feed well on the previous day appear to follow those that did. The behavior of common and lesser kestrels may illustrate different feeding behaviors of similar birds with different roosting habits. The common kestrel hunts vertebrate animals in a small, familiar hunting ground, whereas the very similar lesser kestrel feeds on insects over a large area. The common kestrel roost and hunts alone, but the lesser kestrel roosts and hunts in flocks, possibly so one bird can learn from others where to find insect swarms. Finally, there is safety in numbers at communal roosts since there will always be a few birds awake at any given moment to give the alarm. But this increased protection is partially counteracted by the fact that mass roosts attract predators and are especially vulnerable if they are on the ground. Even those in trees can be attacked by birds of prey. The birds on the edge are at greatest risk since predators find it easier to catch small birds perching at the margins of the roost

Which of the following is a disadvantage of communal roosts that is mentioned 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:
Humans are bringing about another global-scale change in the atmosphere: the increase in what are called greenhouse gases. Like glass in a greenhouse, these gases admit the Sun's light but tend to reflect back downward the heat that is radiated from the ground below, trapping heat in the Earth's atmosphere. This process is known as the greenhouse effect. Carbon dioxide is the most significant of these gases – there is 25 percent more carbon dioxide in the atmosphere today than there was a century ago, the result of our burning coal and fuels derived from oil. Methane, nitrous oxide, and CFCs are greenhouse gases as well.
Scientists predict that increases in these gases in the atmosphere will make the Earth a warmer place. They expect a global rise in average temperature somewhere between 1.0 and 3.5 degrees Celsius in the next century. Average temperatures have in fact been rising and the years from 1987 to 1997 were the warmest years on record. Some scientists are reluctant to say that global warming has actually begun because climate naturally varies from year to year and decade to decade, and it takes many years of records to be sure of a fundamental change. There is little disagreement, though, that global warming is looming.
Global warming will have different effects in different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate changes are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields in areas such as the western United States, where temperature and rainfall are expected to increase, while dramatic decreases in rainfall may lead to severe droughts and plunging agricultural yields in parts of Africa, for example.
Warmer temperatures are expected to partially melt the polar ice caps, leading to a projected sea level rise of 50 centimeters by the year 2050. A sea level rise of this magnitude would flood coastal cities, force people to abandon low-lying islands, and completely inundate coastal wetlands. Diseases like malaria, which at present are primarily found in the tropics, may become more common in the regions of the globe between the tropics and the polar regions, called the temperate zones. For many of the world's plant species, and for animal species that are not easily able to shift their territories as their habitat grows warmer, climate change may bring extinction.

What may be the benefit of exaggerated weather conditions for the western United States?

   Scientists do not yet thoroughly understand just how the body of an individual becomes sensitive to a substance that is harmless or even wholesome for the average person. Milk, wheat, and egg, for example, rank among the most healthful and widely used foods. Yet these foods can cause persons sensitive to them to suffer greatly. At first, the body of the individual is not harmed by coming into contact with the substance. After a varying interval of time, usually longer than a few weeks, the body becomes sensitive to it, and an allergy has begun to develop. Sometimes it's hard to figure out if you have a food allergy, since it can show up so many different ways. Your symptoms could be caused by many other problems. You may have rashes, hives, joint pains mimicking arthritis, headaches, irritability, or depression. The most common food allergies are to milk, eggs, seafood, wheat, nuts, seeds, chocolate, oranges, and tomatoes. Many of these allergies will not develop if these foods are not fed to an infant until her or his intestines mature at around seven months. Breast milk also tends to be protective. Migraines can be set off by foods containing tyramine, phenathylamine, monosodium glutamate, or sodium nitrate. Common foods which contain these are chocolate, aged cheeses, sour cream, red wine, pickled herring, chicken livers, avocados, ripe bananas, cured meats, many Oriental and prepared foods (read the labels!). Some people have been successful in treating their migraines with supplements of B-vitamins, particularly B6 and niacin. Children who are hyperactive may benefit from eliminating food additives, especially colorings, and foods high in salicylates from their diets. A few of these are almonds, green peppers, peaches, tea, grapes. This is the diet made popular by Benjamin Feingold, who has written the book “Why your Child is Hyperactive”. Other researchers have had mixed results when testing whether the diet is effective.

The author states that the reason that infants need to avoid certain foods related to allergies has to do with the infant's ___________ .

   Traditional methods of teaching no longer suffice in this technological world. Currently there are more than 100,000 computers in schoolrooms in the United States. Students mediocre and bright alike, from the first stage through high school not only are not intimidated by my computers, but have become avid participants in the computer epoch.

   Kids operating computer implement their curriculum with great versatility. A music student can program musical notes so that the computer will play Beethoven or the Beatles. For a biology class, the computer can produce a picture of the intricate envisage human biology in a profound way. A nuclear reactor is no longer an enigma to students who can see its workings in minute detail on a computer. In Wisconsi, the Chippewa Indians are studying their ancient and almost forgotten language with the aid of a computer. More commonly, the computer is used for drilling math and language concepts so that youngsters may learn at their own speed without trying the patience of their human teachers. The simplest computers aid the handicapped, who learn more rapidly from the computer than from humans. Once irksome, remedial drills and exercises now on computer are conducive to learning because the machine responds to correct answers with praise and to incorrect answers with frowns and even an occasional tear.

   Adolescents have become so exhilarated by computers that they have developed their own jargon, easily understood by their peers but leaving their disconcerted parents in the dark. They have shown so much fervor for computer that they have formed computer clubs, beguile their leisure hours in computer stores, and even attend computer camps. A Boy Scout can get a computer merit badge. One ingenious young student devised a computer game for Atari will earn him $100,000 in royalties This is definitely the computer age. Manufacturers of computers are presently getting tax write – offs for donating equipment to colleges and universities and are pushing for legislation to obtain further deductions for contributions to elementary and high school. Furthermore, the price of computer for home or office is being sold for less than $100. At that price every class in the country will soon have computer kids.

Some animal behaviorists argue that certain animals can remember past events, anticipate future ones, make plans and choices, and coordinate activities within a group. These scientists, however, are cautious about the extent to which animals can be credited with conscious   processing.
Explanations of animal behavior that leave out any sort of consciousness at all and ascribe actions entirely to instinct leave many questions unanswered. One example of such unexplained behavior: Honeybees communicate the sources of nectar to one another by doing a dance in a figure-eight pattern. The orientation of the dance conveys the position of the food relative to the sun's position in the sky, and the speed of the dance tells how  far  the food source is from  the  hive. Most researchers assume that the ability to perform and  encode the dance is innate and  shows no special intelligence. But in one study, when experimenters kept changing the site of the food source, each time moving the food 25 percent father from the previous site, foraging honeybees began to anticipate where the food source would appear next. When the researchers arrived at the new location, they would find the bees circling the spot, waiting for their food. No one has yet explained how bees, whose brains weigh four ten-thousandths of an  ounce,  could  have inferred the location of the new  site.
Other behaviors that may indicate some cognition include tool use. Many animals, like the otter who uses a stone to crack mussel shells, are capable of using objects in the natural environment as rudimentary tools. One researcher has found that mother  chimpanzees  occasionally show their young how to use tools to open hard nuts. In one study, chimpanzees compared two pairs of food wells containing chocolate chips. One pair might contain, say, five chips and three chips, the other four chips and three chips. Allowed to choose which pair they wanted, the  chimpanzees  almost always chose the one with the higher total, showing some sort  of summing ability. Other chimpanzees have learned to use numerals to label quantities of items and do simple sums.

Learning means acquiring knowledge or developing the ability to perform new behaviors. It is common to think of learning as something that takes place in school, but much of human learning occurs outside the classroom, and people continue to learn throughout their lives.
Even before they enter school, young children learn to walk, to talk, and to use their hands to manipulate toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to interact with their parents, siblings, friends, and other people important to their world. When they enter school, children learn basic academic subjects such as reading, writing, and mathematics. They also continue to learn a great deal outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for interacting with other children. After they finish school, people must learn to adapt to the many major changes that affect their lives, such as getting married, raising children, and finding and keeping a job.
Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Psychologists, social workers, criminologists, and other human- service workers need to understand how certain experiences change people's behaviors.
Employers, politicians, and advertisers make use of the principles of teaming to influence the behavior of workers, voters, and consumers.
Learning is closely related to memory, which is the storage of information in the brain.
Psychologists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later retrieves knowledge when we need it. In contrast, psychologists who study learning are more interested in behavior and how behavior changes as a result of a person's experiences.
There are many forms of learning, ranging from simple to complex. Simple forms of learning involve a single stimulus. A stimulus is anything perceptible to the senses, such as a sight, sound, smell, touch, or taste. In a form of learning known as classical conditioning, people learn to associate two stimuli that occur in sequence, such as lightning followed by thunder. In operant conditioning, people learn by forming an association between a behavior and its consequences (reward or punishment). People and animals can also learn by observation - that is, by watching others perform behaviors. More complex forms of learning include learning languages, concepts, and motor skills

 The passage mainly discusses................

Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pot dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a slight graying of the coat. Plants age too, but the signs are much harder to detect.
Most body parts grow bigger and stronger, and function more efficiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflexible. This can make moving very painful.
All the major organs of the body show signs of aging. The brain, for example, works less efficiently, and even gets smaller in size. Thinking processes of all sorts are slowed  down. Old people often have trouble in remembering recent events.
One of the most serious changes of old ago occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flow to  the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result In heart attack.
Aging is not a uniform process. Different parts of the body wear out at different rates. There are great differences among people in their rate of aging. Even the cells of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fibers can never be replaced  once they wear out.
Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.

What happens to memorization when the brain begins to age?

Very few people, groups, or governments oppose globalization in its entirety. Instead,  critics of globalization believe aspects of the way globalization operates should be changed. The debate over globalization is about what the best rules are for governing the global economy so that its advantages can grow while its problems can be solved.
On one side of this debate are those who stress the benefits of removing barriers to international trade and investment, allowing capital to be allocated more efficiently and giving consumers greater freedom of choice. With free-market globalization, investment funds can move unimpeded from the rich countries to the developing countries. Consumers can benefit from cheaper products because reduced taxes make goods produced at low cost from faraway places cheaper to buy. Producers of goods gain by selling to a wider market. More competition keeps sellers on their toes and allows ideas and new technology to spread and benefit others.
On the other side of the debate are critics who see neo-liberal policies as producing greater poverty, inequality, social conflict, cultural destruction, and environmental damage. They say that the most developed nations - the United States, Germany, and Japan - succeeded not because of free trade but because of protectionism and subsidies. They argue that the more recently successful economies of South Korea, Taiwan, and China all had strong state-led development strategies that did not follow neo-liberalism. These critics think that government encouragement of "infant industries"' that is, industries that are just beginning to develop - enables a country to become internationally competitive.
Furthermore, those who criticize the Washington Consensus suggest that the inflow and outflow of money from speculative investors must be limited to prevent bubbles. These bubbles are characterized by the rapid inflow of foreign funds that bid up domestic stock markets and property values. When the economy cannot sustain such expectations, the bubbles burst as investors panic and pull their money out of the country.
Protests by what is called the anti-globalization movement are seldom directed against globalization itself but rather against abuses that harm the rights of workers and the environment. The question raised by nongovernmental organizations and protesters at WTO and IMF gatherings is whether globalization will result in a rise of living standards or a race to the bottom as competition takes the form of lowering living standards and undermining environmental regulations.
One of the key problems of the 21st century will be determining to what extent markets should be regulated to promote fair competition, honest dealing, and fair distribution of public goods on a global scale.

The word "undermining" in the passage mostly means "     ".

Although they are an inexpensive supplier of vitamins, minerals, and high-quality protein, eggs also contain  a high  level of blood cholesterol, one of the major causes of heart diseases. One egg   yolk, in fact, contains a little more than two-thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to plummet in recent years, which in turn has brought about the development of several alternatives to eating regular eggs. One alternative is to eat substitute eggs. These egg substitutes are not really eggs, but they look somewhat like eggs when  they are  cooked. They have the advantage of having low cholesterol rates, and they can be  scrambled  or  used  in baking. One disadvantage, however, is that they are not good for frying, poaching,  or boiling.  A second alternative to regular eggs is a new type of egg, sometimes called 'designer' eggs. These eggs  are produced by hens that are fed low-fat diets consisting of Ingredients such as canola oil, flax, and rice bran. In spite of their diets, however, these hens produce eggs that contain the same amount of cholesterol as regular eggs. Yet, the producers of these eggs claim that eating their eggs will not raise the blood cholesterol in  humans.
Egg producers  claim  that their product has been  portrayed unfairly. They cite scientific studies  to back up their claim. And, in fact, studies on the relationship between eggs and human cholesterol levels have brought mixed results. It may be that it is not the type of egg that is the main determinant   of cholesterol but the person who is eating the eggs. Some people may be  more  sensitive  to  cholesterol derived from food than other people. In fact, there is evidence that certain dietary fats stimulate the body's production of blood cholesterol. Consequently, while it still makes sense to limit one's intake of eggs, even designer eggs, it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol  level.

According to the passage, one yolk contains approximately what fraction of the suggested daily limit for human consumption of cholesterol?

PANDEMIC DISEASES

Diseases are a natural part of life on earth. If there were  no diseases,  the population would grow too quickly, and there would not be enough food or other resources, so in a way, diseases are natural ways of keeping the Earth in balance. But sometimes  they  spread  very  quickly and kill large numbers of people. For example, in 1918, an outbreak of the flu spread  across the world, killing over 25 million people in only six months. Such terrible outbreaks of a disease are called pandemics.

Pandemics happen when a disease changes in a way that our bodies are not prepared to fight.  In 1918, a new type of flu virus appeared. Our bodies had no way to fight this new flu virus, and    so it spread very quickly and killed large numbers of people. While there have  been  many  different pandemic diseases throughout history, all of them have a new thing in    common.

First, all pandemic diseases spread from one person to another very   easily.

Second, while they may kill many people, they generally do not kill people very quickly. A good example of this would be the Marburg virus. The Marburg virus is an extremely infectious disease. In addition, it is deadly. About 70 -80% of all people who  get the Marburg virus  died  from the disease. However, the Marburg virus has not become  a pandemic  because most people die within three days of getting the disease. This means that the virus does not have enough time    to spread a large number of people. The flu virus of 1918, on the other hand, generally took about   a week to ten days to kill its victims, so it had more time to   spread.

While we may never be able to completely stop pandemics, we  can  make  them  less  common. Doctors carefully monitor new diseases that they fear could become pandemics. For example, in 2002, and 2003, doctors carefully watched SARS. Their health warnings may have prevented SARS from becoming a  pandemic.

 According to paragraph 1, how are diseases a natural part of life on   Earth?

Read the passage carefully and choose the correct answer

On 8 August 1967, five leaders - the Foreign Ministers of Indonesia, Malaysia, the Philippines, Singapore and Thailand- sat down together in the main hall of the Department of Foreign Affairs building in Bangkok, Thailand and signed a document. By virtue of that document, the Association of Southeast Asian Nations (ASEAN) was born. The five Foreign Ministers who signed it have been considered as the founders of probably the most successful intergovernmental organization in the developing world today. The document that they signed would be known as the ASEAN Declaration.

It is a short, simply-worded document containing just five articles. It declares the establishment of an Association for Regional Cooperation among the Countries of Southeast Asia to be known as the Association of Southeast Asian Nations (ASEAN) and spells out the aims and purposes of that Association. These aims and purposes are about the cooperation in economy, society, culture, techniques, education and other fields, and in the promotion of regional peace and stability through abiding respect for justice and the principles of the United Nations Charter. It stipulates that the Association will be open for participation by all States in the Southeast Asian region subscribing to its aims, principles and purposes. It proclaims ASEAN as representing the collective will of the nations of Southeast Asia to bind themselves together in friendship and cooperation and, through joint efforts and sacrifices, secure for their peoples and for posterity the blessings of peace, freedom and prosperity. The goal of ASEAN, then, is to create, not to destroy.

The original ASEAN logo presented five brown sheaves of rice stalks, one for each founding member. Beneath the sheaves is the legend "ASEAN" in blue. These are set on a field of yellow encircled by a blue border. Brown stands for strength and stability, yellow for prosperity and blue for the spirit of cordiality in which ASEAN affairs are conducted. When ASEAN celebrated its 30^th Anniversary in 1997, the sheaves on the logo had increased to ten -representing all ten countries of Southeast Asia and reflecting the colors of the flags of all of them. In a very real sense, ASEAN and Southeast Asia will be one and the same, just as the founders had envisioned.

The pronoun "it" in the first paragraph refers to ________.

Shyness may not seem to be a serious complaint, but for some who suffer from it, it can become unbearable. Even talking to a small group of people you know can seem like an ordeal- it can feel as if you’ve been asked to give a speech on a topic you know very little about to a number of experts. You start to feel hot and shaky, your heart beats faster, your knees feel weak, you begin to stutter and the whole experience seems to last forever.
The fact of the matter is that shyness is something we often recognize in others: “blushing” is one of the more visible signs, for example. Yet we don’t judge someone harshly because of this. But shyness does mean that you are harder to approach, so you become more  isolated. As one shy person put it, “It’s like being in a prison, and it’s very hard to break out.”
Experts on the subject have come up with various possible solutions, and one has been singled out as being the key to success- namely, finding an interest in common with the other people. Spending a lot of time on the sidelines watching other people and envying them because they are much more outgoing doesn’t help; remembering that some of those people you most envy are probably shy themselves, does. The secret is how you deal with it. And experts have come up with four things you can do today to help. Firstly, you can start by listening to other people. You will find yourself getting interested in what they’re talking about and asking questions- and before you know it, you’ll be having a conversation.
Secondly, you could try asking neighbors if you can walk their dog. Like children, pets can be excellent icebreakers for conversations with passers-by. Thirdly, try joining a class to learn something like tap-dancing or flamenco, where people are likely to laugh a lot. You’ll feel relaxed, and also you’ll be much too busy concentrating on what you are doing to feel shy. Lastly, try telling yourself that it doesn’t matter if you say or do something silly. Most people make a fool of themselves every so often- and it’s not the end of the world if you do!

One of the symptoms of shyness in a stressful situation is____

New surveys suggest that the technological tools we use to make our lives easier are  killing our leisure time. We are working longer hours, taking fewer and shorter vacations (and when we do go away, we take our cell phones, PDAs, and laptops along). And, we are more stressed than ever as increased use of e-mail, voice mail, cell phones, and the Internet is destroying any idea of  privacy and leisure.
Since the Industrial Revolution, people have assumed that new labor-saving devices would free them from the burdens of the workplace and give them more time to grow intellectually, creatively, and socially -exploring the arts, keeping up with current events, spending more time with friends and family, and even just ''goofing off''.
But here we are at the start of the 21st century, enjoying one of the greatest technological boom times in human history, and nothing could be further from the truth. The very tools that were supposed to liberate us have bound us to our work and study in ways that were inconceivable just a few years ago. It would seem that technology almost never does what we expect.
In 'the old days', the lines between work and leisure time were markedly clearer. People  left their offices at a predictable time, were often completely disconnected from and out of touch with their jobs as they traveled to and from work, and were off-duty once they were home. That is no longer true. In today's highly competitive job market, employers demand increased productivity, expecting workers to put in longer hours and to keep in touch almost constantly via fax, cell phones, e-mail, or other communications devices. As a result, employees feel the need to check in on what is going on at the office, oven on days off. They feel pressured to work after hours just to catch up on everything they have to do. Workers work harder and longer, change their work tasks more frequently, and have more and more reasons to worry about job security.
Bosses, colleagues, family members, lovers, and friends expect instant responses to voice mail and e-mail messages. Even college students have become bound to their desks by an environment in which faculty, friends, and other members of the college community increasingly do their work online. Studies of time spent on instant messaging services would probably show staggering use.
This is not what technology was supposed to be doing for us. Now technologies, from genetic research to the Internet, offer all sorts of benefits and opportunities. But, when new tools make life more difficult and stressful rather than easier and more meaningful - and we are, as a society, barely conscious of it - then something has gone seriously awry, both with our expectations for technology and our understanding of how it should benefit us.

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.

   Experts in climatology and other scientists are becoming extremely concerned about the changes to our climate which are taking place. Admittedly, climate changes have occurred on our planet before. For example, there have been several ice ages or glacial periods. These climatic changes, however, were different from the modern ones in that they occurred gradually and, as far as we know, naturally. The changes currently being monitored are said to be the result not of natural causes, but of human activity. Furthermore, the rate of change is becoming alarmingly rapid.

   The major problem is that the planet appears to be warming up. According to some experts, this warming process, known as global warming, is occurring at a rate unprecedented in the last 10,000 years. The implications for the planet are very serious. Rising global temperatures could give rise to such ecological disasters as extremely high increases in the incidence of flooding and of droughts. These in turn could have a harmful effect on agriculture.

   It is thought that this unusual warming of the Earth has been caused by so-called greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car engines and modern industrial processes, for example. Such gases not only add to the pollution of the atmosphere, but also create a greenhouse effect, by which the heat of the sun is trapped. This leads to the warming up of the planet.

   Politicians are also concerned about climate change and there are now regular summits on the subject, attended by representatives from around 180 of the world’s industrialized countries. Of these summits, the most important took place in Kyotoin Japanin 1997. There it was agreed that the most industrialized countries would try to reduce the volume of greenhouse gas emissions and were given targets for this reduction of emissions.

   It was also suggested that more forests should be planted to create so-called sinks to absorb greenhouse gases. At least part of the problem of rapid climate change has been caused by too drastic deforestation. Sadly, the targets are not being met. Even more sadly, global warnings about climate changes are often still being regarded as scaremongering.

According to the passage, agriculture could ____.
