A growing amount of research shows a pessimistic outlook can take a huge toll （损失) o

n your health. This may be because pessimists are not as good as optimists at handling stress, which damages the immune system and causes other health problems, such as high blood pressure. Optimists go into situations with more confidence, so events seem less threatening and stressful. And in situations where stress is unavoidable, positive thinkers also have stronger coping methods. Looking at the bright side may also lead to a longer life. Researchers have found that those who were pessimists had a 19 percent increased risk of death. Studies of HIV patients also have found that the health of optimists doesn’t decline as rapidly.Fortunately, even a confirmed negativist (否定论者) can change. To start with, experts recommend using a trick called creative accounting. Keep a mental checklist of all the good things that happen to you. Simply focusing on the positive can boost (提升) your mood. You can also try to avoid upward comparison. There will always be someone prettier or wealthier, but constantly comparing yourself to them will leave you feeling down and envious (妒忌的).Finally, recognize how your mood affects your outlook. Optimists know that if they are in good spirits, their day-after-day experiences and interactions are more positive. So see if you can muster (鼓起，振起) a smile. The result might be a happier — and healthier — you.

With the steady increase in the amount of leisure time that people enjoy today, the import
ance of businesses that deal with leisure products and services is also steadily increasing.

One of the biggest such industries is the tourist industry. Providing transportation and accommodations for tourists—and guides, brochures, souvenirs—is one of the major industries in many countries.

Another industry obviously devoted to leisure is entertainment. Movies, TV, shows, concerts and plays are usually intended for our leisure. The same can be said of most books, except textbooks.

This list could be greatly extended. But even among these industries, we have mentioned only part of the picture. The people who make TV sets and build the theatres and hotels are as much a part of the leisure industry as the singers or the hotel clerks.

Until recently the opportunities for criminal activities on the Internet have been lo
Until recently the opportunities for criminal activities on the Internet have been low. However， the volume of business done on the Internet is growing rapidly，as people order books and other products and make money transactions. All this is creating temptations for hackers(黑客).

Hackers are often young people who are interested in computers. They use them to move quietly to the Internet，looking for ways to break into computers systems run by banks，telephone companies and even Government departments. They look for examples of credit cards and try to steal the numbers.

Hackers rarely admit to a successful break-in. The first indication of a hacking may be when a customer discovers a wrong money transaction on a credit card account. It is harder to check on somebody misusing an online connection unless there is a massive down load of information which would call the attention of the consumer.

The main idea of the first paragraph is that ______.

A. the opportunities for criminal activities on the Internet have been low

B. the opportunities for criminal activities on the Internet are low

C. there are more opportunities for criminal activities on the Internet

D. people should not make money transactions on the Internet

The word "temptations" in the first paragraph is closest in meaning to ______.

A. interests

B. attractions

C. benefits

D. profits

In the passage， it's said that hackers may attack the Internet system of all the following institutions except _____.

A. banks

B. telephone companies

C. universities

D. government departments

Which of the following is not the reason for a hacking being found？

A. The customer found something wrong with his account.

B. There was a huge amount of information being downloaded.

C. There was a wrong money transaction.

D. The hacker proudly admitted his successful break-in.

In the last sentence of the paragraph， "somebody" refers to a______.

A. customer

B. card user

C. hacker

D. bank clerk

第6题

To get a chocolate out of a box requires a considerable amount of unpacking: the box has t
o be taken out of the paper bag in which it arrived, the cellophane wrapper has to be torn off, the lid opened and the paper removed, the chocolate itself then has to be unwrapped from its own piece of paper. But this overuse of wrapping is not confined to luxuries. It is now becoming increasingly difficult to buy anything that is not done up in beautiful wrapping.

The package itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much of the refuse put out by the average London household each week. So why is it done？ Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up scarce energy and re sources and messing up the environment.

Recycling is already happening with milk bottles which are returned to the dairies, washed out, and refilled. But both glass and paper are being threatened by the growing use of plastic. More dairies are experimenting with plastic bottles.

The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to do away with plastic altogether in the shops, a suggestion unacceptable to many manufacturers who say there is no alternative to their handy plastic packs.

It is evident that more research is needed into the recovery and re-use of various materials and into the cost of collecting and recycling containers as opposed to producing new ones. Unnecessary packaging, intended to be used just once, and make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of doing away with packaging as using it sensibly. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function.

"This overuse of wrapping is not confined to luxuries." (line 4, Paragraph 1) means ______.

A．more wrapping is needed for ordinary products

B．more wrapping is used for luxuries than for ordinary products

C．too much wrapping is used for both luxury and ordinary products

D．the wrapping used for luxury products is unnecessary

3 Clyde Williams is facing a dilemma. He has successfully built up a small family-owned co
mpany, Concrete Solutions

Ltd, manufacturing a range of concrete based products used in making roads, pavements and walkways. The

production technology is very low tech and uses simple wooden moulds into which the concrete is poured. As a

consequence he is able to use low skilled and low cost labour, which would find it difficult to find alternative

employment in a region with high unemployment levels. The company has employed many of its workforce since its

creation in 1996. The company’s products are heavy, bulky and costly to transport. This means its market is limited

to a 30-mile area around the small rural town where the manufacturing facility is located. Its customers are a mix of

private sector building firms and public sector local councils responsible for maintaining roads and pavements. By its

nature much of the demand is seasonal and very price sensitive.

A large international civil engineering company has recently approached Clyde with an opportunity to become a

supplier of concrete blocks used in a sophisticated system for preventing coast and riverbank erosion. The process

involves interlocking blocks being placed on a durable textile base. Recent trends in global warming and pressure in

many countries to build in areas liable to flooding have created a growing international market for the patented erosion

prevention system. Clyde has the opportunity to become the sole UK supplier of the blocks and to be one of a small

number of suppliers able to export the blocks to Europe. To do it he will need to invest a significant amount in CAM

(computer aided manufacturing) technology with a linked investment in the workforce skills needed to operate the

new technology. The net result will be a small increase in the size of the labour force but redundancy for a significant

number of its existing workers either unwilling or unable to adapt to the demands of the new technology. Successful

entry into this new market will reduce his reliance on the seasonal low margin concrete products he currently produces

and significantly improve profitability.

One further complication exists. Concrete Solutions is located in a quiet residential area of its home town. Clyde is

under constant pressure from the local residents and their council representatives to reduce the amount of noise and

dust created in the production process. Any move into making the new blocks will increase the pollution problems

the residents face. There is a possibility of moving the whole manufacturing process to a site on a new industrial estate

being built by the council in a rival town. However closure of the existing site would lead to a loss of jobs in the current

location. Clyde has asked for your help in resolving his dilemma.

Required:

(a) Using models where appropriate, advise Clyde on whether he should choose to take advantage of the

opportunity offered by the international company. (12 marks)

Will We Run Out of Water？Picture a "ghost ship" sinking into the sand, left to rot on dry

Will We Run Out of Water？

Picture a "ghost ship" sinking into the sand, left to rot on dry land by a receding sea. Then imagine dust storms sweeping up toxic pesticides and chemical fertilizers from the dry seabed and spewing them across towns and villages.

Seem like a scene from a movie about the end of the world？ For people living near the Aral sea (咸海) in Central Asia, it's all too real. Thirty years ago, government planners diverted the rivers that flow into the sea in order to irrigate (provide water for) farmland. As a result, the sea has shrunk to half its original size, stranding (使搁浅) ships on dry land. The seawater has tripled in salt content and become polluted, killing all 24 native species offish.

Similar largecale efforts to redirect water in other parts of the world have also ended in ecological crisis, according to numerous environmental groups. But many countries continue to build massive dams and irrigation systems, even though such projects can create more problems than they fix. Why？ People in many parts of the world are desperate for water, and more people will need more water in the next century.

"Growing populations will worsen problems with water," says Peter H. Gleick, an environmental scientist at the Pacific Institute for studies in Development, Environment, and Security, a research organization in California. He fears that by the year 2025, as many as one-third of the world's projected (预测的) 8.3 billion people will suffer from water shortages.

WHERE WATER GOES

Only 2.5 percent of all water on Earth is freshwater, water suitable for drinking and growing food, says Sandra Postel, director of the Global Water Policy Project in Amherst, Mass. Two-thirds of this freshwater is locked in glaciers (冰山) and ice caps (冰盖). In fact, only a tiny percentage of freshwater is part of the water cycle, in which water evaporates and rises into the atmosphere, then condenses and falls back to Earth as precipitation (rain or snow).

Some precipitation runs off land to lakes and oceans, and some becomes groundwater, water that seeps into the earth. Much of this renewable freshwater ends up in remote places like the Amazon river basin in Brazil, where few people live, In fact, the world's population has access to only 12,500 cubic kilometers of freshwater—about the amount of water in Lake Superior(苏必利尔湖). And people use half of this amount already. "If water demand continues to climb rapidly," says Postel, "there will be severe shortages and damage to the aquatic (水的) environment."

CLOSE TO HOME

Water woes(灾难) may seem remote to people living in rich countries like the United States. But Americans could face serious water shortages, too especially in areas that rely on groundwater. Groundwater accumulates in aquifers (地下蓄水层), layers of sand and gravel that lie between soil and bedrock. (For every liter of surface water, more than 90 liters are hidden underground.) Although the United States has large aquifers, farmers, ranchers, and cities are tapping many of them for water faster than nature can replenish(补充) it. In northwest Texas, for example, overpumping has shrunk groundwater supplies by 25 percent, according to Postel.

Americans may face even more urgent problems from pollution. Drinking water in the United States is generally safe and meets high standards. Nevertheless, one in five Americans every day unknowingly drinks tap water contaminated with bacteria and chemical wastes, according to the Environmental Protection Agency. In Milwaukee, 400,000 people fell iii in 1993 after drinking tap water tainted with cryptosporidium (隐孢子虫), a microbe (微生物) that causes fever, diarrhea (腹泻) and vomiting.

Where so contaminants come from？ In developing countries, people dump raw (未经处理的) sewage(污水) into the same streams and rivers from which they draw water for drinking and co

Population tends to grow at an exponential（指数的)rate. This means that they progressively

Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate take one penny and double every day for one month. After the first week, you would have only 64 cent, but after the fourth week you would have over a million dollars.

This helps explain why the population has come on“all of a sudden” took from he beginning of human 1ife to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行) a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960 only thirty years and in 1975 world population reached 4 billion which is another billion people in only fifteen years.

World population is increasing at a rate of 9, 000per hour, 220,000 per day and 80 million per year.

This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.

Some countries such as Columbia, Thailand, Morocco, Costa Rica and the Philippines are doubling their population about every twenty-one years with a growth rate of 3.3 percent a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8 percent per year.Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.

This passage chiefly discusses

A.the growth of world population.

B.one type of the exponential rate

C.the population problem of more rapidly growing countries.

D.the possible ways of dealing with the rapid population growth

According to the passage what helps to explain why the population problem has come on “all of a sudden”？A.The penny that doubles itself every day for one month

B.The time span of at 1east two million years in human history.

C.An illustration of the exponent growth rate given by the author.

D.The large amount of money you would luckily make after the fourth week

Which of the following statements is NOT true？A.World population is increasing at a rate of 150 per minute

B.Lower death rate also contributes to world population growth

C.The population of Columbia has been doubling every year for 21 years.

D.The United States is usually doubling its population on about every 87 years.

It took ______ for the world to increase its population from 1 billion to 4 billion.A.100 years

B.175 years

C.1975 years

D.over two million years

When a population doubles, the country involved needs twice as much of everything including __.A.hospitals and medicines

B.schools and students

C.food and manpower resources

D.all of the above
