With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills(泄露) on people, nature, and the environment.

Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea.

Of all of today’s environmental disasters, an oil spill may actually be one of the least serious. Although oil is poisonous, it is a natural material. In the end, it breaks down naturally. There are, of course, long-term effects, but it is usually more serious in the short term.

Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible. In 1967 the tanker Torrey Canyon sank off the Sicily Isles near the coast of England and spilled 120,000 tones of oil into the ocean. If you go there today, you will find it hard to see any sign that it ever happened.

Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!

We should be thinking more about reducing our dependency on oil. Governments should be encouraging research into new technologies, such as cars run by solar power(太阳能), electricity, hydrogen, and so on. Much of this research has, in the past, been held back by the oil, gas, and coal.

If the world’s millions of cars were 10% more efficient(高效的) — and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too.

What is the passage mainly talking about?

A. Oil tanker accidents. B. What oil pollution is.

C. Oil spills pollution. D. How to reduce oil pollution.

How does the author support the idea that oil spills are not as serious as people believe?

A. By giving an example. B. By making an argument.

C. By giving a description. D. By drawing a diagram.

What does the underlined word “risk” in Paragraph 5 refer to?

C. Millions of tons of oil spilling into the sea.

D. Poisonous oil breaking down naturally.

Which suggestion is made for reducing oil tank accidents according to the passage?

B. Tankers should not be allowed to sail near the coastlines.

C. We should develop new technologies to cut oil use.

D. Countries should build more oil pipelines under the sea.

Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to get round this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp（安培） current to store this electricity, and a lamp whose bulb is a light-emitting diode（二极管）. The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again.
The trick is that, to be able to use the electricity, the system's keeper must buy a scratch card—for as little as a dollar—on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit.
Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards—which Eight19 expects would take the average family around 18 months—the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell.
In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably.
According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil—enough to fuel a couple of smoky lamps—plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the cost of solar technology falls, it should get even cheaper.
【小题1】The underlined word “get round” in the first paragraph can be replaced by _______ .

【小题2】What should the user do when the electricity in the battery is used up?

A．Buy a scratch card.	B．Recharge it outside.
C．Buy another solar cell.	D．Return it to the company.

【小题3】How much would users pay for the cell and scratch cards before they own a 2.5-watt solar cell?

【小题4】It can be inferred from the last paragraph that ____________.

A．Kenyan families would find it difficult to afford the solar cell

B．using the solar cell would help Kenyan families save money

C．few Kenyan families use mobile phones for lack of electricity

D．the company will make a great profit from selling solar cells

【小题5】What might be the most suitable title for the passage?

A．Solar Energy: Starting from Scratch.

B．Eight19: a creative British Company.

C．Kenyan Families: Using Solar Energy for Free.

D．Poor Countries: Beginning to Use Solar Energy.

Scientific discoveries have changed man's life a great deal during the past century. First of all, they have greatly improved material well-being in several areas of life. In the field of medicine, cures for life threatening diseases have enabled people to live longer. In communication, the telephone and e-mail have made it possible for us to communicate with anyone in the world without leaving our homes or offices. Advances in transportation allow businessmen to fly across the ocean in the morning and return home the same evening. Space technology has put men on the moon. More efficient ways of using available resources, such as coal and solar power, have been explored.

Scientific discoveries have also changed man's moral atmosphere. Ethical (伦理的) issues are raised by these discoveries. Should we keep a terminally ill person alive through drugs and machines or should we allow him to die in dignity? With advances in transportation had come the problem of pollution for nearly every major city in the world. If cities become uninhabitable, then such technical advances may come with too great a price to pay. Many people also question the wisdom of sending men to the moon when there are urgent problems that have not been solved on earth. During future years, increasing attention must be given to the moral as well as the practical applications of science.

D. Men are sent to the moon because there are urgent problems that have not been solved on earth.

3.At the end of the passage the author says that increasing attention must be given to _________.
