I want to talk about the economy．Not "the economy" we hear about endlessly in the news each day and in politicians' speeches．I want to talk about the real economy, the one we live in day by day．

Most people aren't particularly interested in "the economy"．"Share prices are flying high; interest rates are soaring(令人伤心的）; the Dow Jones Index closed sixty-three points down on 8472．35．" We hear this and subconsciously switch off．

Notice that "the economy" is not the same as the economy, "The economy" is what men in suits play with to make vast personal wealth．The economy is where the rest of us live on a daily basis, earning our living, paying our taxes, and purchasing the necessities of life．

We are supposed to be benefiting from all the advantages of a well-off society．So why do we feel tired and stressed? We have no time for anything other than work, which is ridiculous given the number of labor-saving devices in our lives．Our towns become more and more crowded．We poison our air and seas, and our food is full of chemicals．There's something wrong here．If times were truly good, then you may think we'd all feel optimistic about the future．Yet the majority of us are deeply worried．More than 90 percent of us think we are too concerned about ourselves and not concerned enough about future generations．

The term "economic expansion" suggests something desirable, but expansion simply means spending more money．More spending doesn't mean that life is getting better. We all know it often means the opposite - greed, crime, poverty, pollution. More spending merely feeds our whole economic system, which is based on production and consumption. Unless money keeps circulating, the economy breaks down. If we don't keep consuming, the whole system goes into stalemate（僵局）．

How do we break the cycle and make some changes? We need to become far more aware of the results of our actions. We buy clothes that are made in sweat shops by virtual slaves in poor parts of the world. We create mountains of waste. We demand cheap food, mindless of the fact that it totally lacks taste and is produced using chemicals that poison the land．

The consumption（消费） culture makes us unaware of the effect of our own behavior. Our main problem is not that we don't know what to do about it. It is gathering the desire to do it．

1.According to the author, which one belongs to the real economy?

A．The Dow Jones Index． B．Increases in interest rates．

C．Shopping in a supermarket． D．Skyrocketing share prices．

2.It can be concluded from Paragraph 4 that ．

A．people are benefiting from a well-off society

B．the future generation is a big concern for most people

C．the majority of people are optimistic about the future

D．people still feel much pressure despite labor-saving devices

3.What is true about economic expansion?

A．It may lead to some social problems．

B．It guarantees a better life for us．

C．It will stop the circulation of money．

D．It has only brought desirable effects．

4.The author writes the passage mainly to ．

A．suggest a solution for over-consumption

B．call on us to change our behavior

C．make a distinction between two economies

D．inform us of the effects of economic expansion

Terraforming (Earth-forming) other planets, also known as planetary engineering (行星工程), seems like a task still centuries away for mankind to accomplish. However, it is a vigorous topic that attracts both popular and scientific interest. Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it’s a good idea?

Mankind is getting more and more hard facts about other planets. The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury, Jupiter and Saturn have been studied by spacecraft. Speculations have been answered; new questions have been raised, and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.

In the past, people with excellent ideas about terraforming have kept them to themselves, or buried them in a desk drawer because they did not realize that anyone else was interested. But now, a wide circle of people has begun to do this kind of work. For instance, NASA funded a project on transforming Mars.

There are several strong reasons which demand that the possibilities of terraforming be studied carefully. First, it’s an exciting idea of a possible future for human beings. Such thinking has a valuable role in providing options for our future directions. Secondly, the techniques of terraforming will also help contemporary technologies in weather and climate control. Thirdly, such study may assist us in detecting any possible existence of extraterrestrial intelligence (SETI, The Search for Extraterrestrial Intelligence, 地外文明搜索) and alien (异己的) civilizations on other planets.

Though the mission is far beyond our reach at the moment, we should at least keep our options open. Through debate and study on this subject, the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.

1..

. According to the context, what’s the meaning of the word “speculation” in paragraph 2?

A. The act of discussing something with a group of people.

B. The act of studying and researching.

C. The act of guessing without knowing all the facts about something.

D. The acting of writing letters to a certain organization.

2..

Why did people keep the idea of terraforming to themselves in the past?

A. They thought no one else would show interest in the idea.

B. They gradually came to find the idea crazy.

C. They thought the idea would never come true.

D. They had few resources for further study on this topic.

3..

. Which is NOT the reason to support the study of terraforming?

A. Even if we don’t succeed in terraforming, such study may help us to better understand technologies such as climate and weather control.

B. Such study may explore a new direction of development for human beings.

C. Such study may enable us to find the lives on other planets.

D. As the resources on Earth are being drained, it’s very urgent to study how to migrate (迁移) to other planets。

4..

What’s the main idea of the article?

A. It’s highly possible that terraforming other planets will come true so we should increase investing in this program.

B. Even if the idea of terraforming other planets may take centuries to realize, we have many reasons to support such studies.

C. Terraforming other planets is the best option for human being’s future.

D. More and more people are taking planetary engineering as their occupation.

Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use. This is especially true in agriculture, where sustainable development is often taken as the only measure of progress without a proper appreciation of historical and cultural perspectives.

To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so. Medieval agriculture in northern Europe fed, clothed and sheltered a popularly rural society with a much lower population density than it is today. It had smallest effect on biodiversity, and any pollution it caused was typically localized. In terms of energy use and the nutrients captured in the product it was relatively inefficient.

Contrast this with farming since the start of the industrial revolution. Competition from overseas led farmers to specialize and increase yields. Throughout this period food became cheaper, safer and more reliable. However, these changes have also led to habitat loss and to decreasing biodiversity.

What’s more, demand for animal products in developing countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050.yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions.

All this means that agriculture in the 21^st century will have to be very different from how it was in the 20th. This will require complete thinking. For example, we need to move away from the idea that traditional practices are unavoidably more sustainable than new ones. We also need to abandon the idea that agriculture can be “zero impact”. The key will be to abandon the rather simple and unchangeable measures of sustainability, which centre on the need to maintain production without increasing damage.

Instead we need a more dynamic explanation, one that looks at the pros and cons of all the various way land is used. There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity. It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting. But we do not know whether lower carbon footprints will always be better for biodiversity.

What is critical is recognizing that sustainable agriculture is not just about sustainable food production.

1.How do people often measure progress in agriculture?

A．By its productivity.

B．By its impact on the environment.

C．By its sustainability.

D．By its contribution to economic growth.

2.What does the author think of traditional farming practices?

　　A．They have remained the same over the centuries.

　　B．They have not kept pace with population growth.

　　C．They are not necessarily sustainable.

　　D．They are environmentally friendly.

3.What will agriculture be like in the 21st century?

　　A．It will go through thorough changes.

　　B．It will supply more animal products.

　　C．It will abandon traditional farming practices.

　　D．It will cause zero damage to the environment.

4.What is the author’s purpose in writing this passage?

　　A．To remind people of the need of sustainable development.

　　B．To suggest ways of ensuring sustainable food production.

　　C．To advance new criteria for measuring farming progress.

　　D．To urge people to rethink what sustainable agriculture is.

The following people are expressing their thoughts (1--5) to show their concern for food, environment and so on. After that are pieces of related information (A--F). Now decide which piece of information would be most suitable for the thought and idea mentioned in questions61---65 and mark your answer letter (A---F) on your answer sheet. There is one extra paragraph which you do not need to use.

______ 1.How I was struck by the clear water and fresh air in my childhood! But everything has changed, that is, the clear water and fresh air are nowhere to be found again as they were. Above all, a great deal of waste hardly rots away.

______ 2.More and more people are beginning to have a good knowledge of the importance of a safer and cleaner environment, which in turn forces the business to be cleaned up.

______ 3. Organic products are getting more and more popular among people, but we should know the fact that organic products might also have something to do with pesticides (农药).

______ 4.I’m very much fond of growing some vegetables of my own in my small garden, for many vegetables on sale in markets are actually becoming more and more dangerous as a result of widespread pesticides.

______ 5. Nowadays it is very convenient for consumers to find and buy green food in supermarkets as they are clearly marked.

A. “Organic produce is always better,” Gold said. “The food is free of pesticides, and you are generally supporting family farms instead of large farms. And more often than not it is locally grown and seasonal, so it is more tasty.” Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business.

B. Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences - but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported to meet growing demand. “The demand for organic food is increasing by about one third every year, so it is a very fast-growing market,” said Sue Flock, a specialist in this line of business.

C. Many cities around the world today are heavily polluted. Careless methods of production and lack of consumer demand for environment-friendly products have contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic, and metal containers are produced, and these are difficult to get rid of.

D. However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these: “Will this shampoo damage the environment?” “Can this metal container be reused or can it only be used once?”

E. Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels (标签) to show that the product is green. Some companies have made the manufacturing (制造) of clean and safe products their main selling point and emphasize it in their advertising.

F. The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of “Buy it, use it, throw it away, and forget it.” The public pressure is on, and gradually business is cleaning up its act.
