The oil resources which are left will not last very long. This means that all vehicles such as cars, trains, buses, planes and ships that need oil to work will not be able to run. So it will be necessary to develop a new system of transport which uses a fuel more than oil. Electric vehicles are one possibility. In Britain, most families have at least one car and this car is used every day. It could be that only one person in the family drives the car to work or for shopping. The number of cars on the road which are almost empty perhaps helps to explain why the oil is used up so quickly. The family car is a very useful form of transport but it is also a great waste of energy, especially if it is compared with buses or trains. Much petrol is used by a car which is traveling at 120 kilometers an hour. Clearly, it would be better if there were fewer cars on the road and more speed limits so that the oil which is left will last as long as possible.

About 25% of Britain’s total consumption of energy is domestic—it is used only in the home. Just over 20% is used for transport. Most of the energy is used in industry. It is difficult to suggest any possible energy conservation in industry because many of the suggestions would mean that some people would lose their jobs. It is important that industry produces the same amount of products using the same amount of workers.

Obviously, conservation is not going to be the answer to the energy crisis（危机）. The most it can do is to give more time for a better solution to be found. The more time which is available for new sources of energy to be developed, the better it is because there is still a lot of work to be done in order to find suitable, safe methods of producing energy.

1.In Britain, what reason could help to explain why oil is used up very quickly?

A．People use cars every day.

B．Most families have at least one car.

C．Many cars on the road are almost empty.

D．Electric vehicles are used.

2.Which of the following is true?

A．Compared with buses and trains, the family car is useful and can save energy.

B．A car driving at the speed of 80 kilometers per hour uses half as much petrol as a car traveling at 160 kilometers per hour.

C．It is possible for people to develop vehicles.

D．Limitation of the number of cars on the road and their speed will help the oil last longer.

3.What does the underlined word “domestic” mean in Paragraph Two?

A．For household use. B．On the road.

C．Slow driving. D．Fast driving.

4.What is a better way to solve the problem of the energy crisis?

A．Governments should cut down the number of family cars on the road.

B．The speed of vehicles must be limited.

C．New sources of energy should be found and developed.

D．Factories should cut down on production.

Many road accidents occur because drivers cannot ______ the speed of approaching vehicles.

A．conclude B．count C．measure D．value

When Albert Einstein was young, he was a quiet child who spent much of his time alone. He was slow to talk and had difficulty in learning to read.

When Albert was five years old, his father gave him a compass. Albert was filled with wonder when he discovered that the compass needle always pointed in the same direction ---- the north. He asked his father and his uncle what caused the needle to move. Their answers were difficult for Albert to understand. Yet he spent a lot of time thinking about them. He said later that he felt something must be hidden behind things.

Albert didn’t like school. The German schools of that time were not pleasant. Students couldn’t ask questions. Albert said he felt as if he were in prison..

One day Albert told his uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by pretending to be a policeman. “You are looking for someone,” he said, “but you don’t know who he is. Call him X. Find him by using your mathematical tools.”

Albert learned to love mathematics. He was studying the complex mathematics of calculus while all his friends were still studying simple mathematics. Instead of playing with his friends he thought about things such as “What would happen if people could travel at the speed of his light?”

Albert wanted to teach mathematics and physics. He graduated with honors, but it was a pity that he could not get a teaching job.

1.According to Paragraph 2, we can learn that Albert Einstein ________.

A．was interested in the compass

B．wanted to be a great scientist

C．was not clever enough

D．didn’t like thinking by himself

2.Why did Albert Einstein hate school?

A．He couldn’t play with his friends there

B．Students were not allowed to ask questions.

C．The schools were like prisons at that time

D．He had to learn mathematics that he didn’t like.

3.What does the underlined word ‘complex’ probably mean?

A．Useful

B．Difficult

C．Boring

D．Interesting

4.We can learn from the passage that ________.

A．Einstein became a mathematics teacher after graduation

B．Einstein gradually loved mathematics with his uncle’s help.

C．Einstein’s uncle was a policeman.

D．Einstein liked playing with other children.

Edward Wilson is America’s, if not the world’s, leading naturalist. In The Future of Life, he takes us on a tour of the world’s natural resources(资源). How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity(生物多样性)of our earth.

Wilson begins with an open letter to the pioneer in environment (环境) protection, Henry David Thoreau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Can the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?

Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species(物种) are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.

At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book.

1. We learn form the text that Wilson cares most about ______

A．the environment for plants	B．the biodiversity of our earth
C．the wastes of natural resources	D．the importance of human values

2. How many species are most important to our present food supply?

A．Twenty.

B．Eighty.

C．One hundred

D．Ten thousand.

3. Wilson suggests that one way to keep biodiversity is to _______.

A．learn how to farm scientifically

B．build homes for some dying species

C．make it clear what to eat

D．use more species for food

4. We can infer that the text is _______

A．a description of natural resources

B．a research report

C．a book review

D．an introduction to a scientist.

5. Edward Wilson is _______

A．a pioneer in environment protection

B．an American scientist in environment protection

C．a world-famous scientist in Asia

D．a well-known expert in nature in U.S.A
