Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.

Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.

Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.

The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (災難性的) levels unless we develop power sources that are both cheaper and cleaner.

It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.

1.According to the passage, the science of the future is likely to be ________.

A. electronics B. biotechnology

C. genetic engineering D. nuclear technology

2.The materials produced with organic chemistry are ________.at present.

A. as good as wool

B. as good as an insect's body

C. better than natural materials

D. not as good as natural materials

3.According to the passage, it may soon be possible ________.

A. to transplant human organs

B. to make artificial hearts and eyes

C. to produce drugs without side effects

D. to make something as good as human skin

4.In 1996, Arthur C. Clarke predicted that_______.

A. the Chernobyl disaster would happen in two years

B. we will never stop using non-renewable power sources biological

C. oil, gas and coal could be repeatedly used in the future

D. power sources would be put into use soon

5.What do we learn from the last paragraph?

A. Biological power will keep all its promises.

B. Biological power is cheaper than nuclear power.

C. Biotechnology can solve all our future energy problems

D. Biological power may not be as dangerous as nuclear power

Many everyday American expressions are based on colors.

Red is a hot colour. Americans may say they are red hot about something unfair. They are red hot when they are very angry about something. The small hot?tasting peppers found in many Mexican foods are called red hot for their colour and their fiery(辣的) taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz.

Pink is a lighter kind of red. People sometimes say they are in the pink when they are in good health. The expression was first used in America at the beginning of the twentieth century. It comes from the fact that many babies are born with nice pink skin that shows that they are in good health.

The colour black is often used in expressions. People describe a day on which everything goes wrong as a black day. A blacklist (黑名單) is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.

The colour green is natural for trees and grass. But it is，an unnatural colour for humans. A person who has a sick feeling in his stomach may say he feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.

Sometimes a person may be upset because he does not have something as nice as a friend has. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because green is the colour of the back side of the paper money.
