There are four reading passages in this part. Each passage is followed by five questions. For e ach question there are four suggested answers marked A, B, C and D. Choose one best answe
r and blacken the corresponding letter on the Answer Sheet.Passage One
In ancient times wealth was measured and exchanged in things that could be touched: food, to ols, and precious metals and stones. Then the barter system was replaced by coins, which still had real value since they were pieces of rare metal. Coins were followed by fiat money, pap er notes that have value only because everyone agrees to accept them.
Today electronic monetary systems are gradually being introduced that will transform money in to ev en less tangible forms, reducing it to a series of “bits and bytes”, or units of computeriz ed information, going between machines at the speed of light. Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries t hrough computers and telecommunications devices.

At the University of Kansas art museum, scientists tested the effect of different colored walls on two groups of visitors to an exhibit of paintings. For the first group the room was painted white; for the second, dark brown. Movement of each group was followed by an electrical eq uipment under the carpet. The experiment showed that those who entered the dark brown walk ed more quickly, covered more area, and spent less time in the room than people in the white one. Dark brown made people more active, but the activity ended sooner. Not only the choic e of colors but also the general appearance of a room affects those inside. Another experiment presented people with photographs of faces whose energy was to be commented. Three group s of people were used; each was shown the same photos, but each group was in an ordinary room—a nice office. The third was in a tastefully designed living room with carpeting.

The water we drink and use is running short in the world. We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Exp eriments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treat ed with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Th en we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt. This process is called desalinization, and it is already in use in many parts of the world.
71. The way to stop wasting our limited water is to ________.
A. do experiments with water
B. purify the used water and reuse it
C. use fresh water once again
D. make use of seawater

Some people hate everything that is modern. They cannot imagine how anyone can really like modern music; they find it hard to accept the new fashions in clothing; they think that all m odern painting is ugly; and they seldom have a good word for the new buildings that are bein g built everywhere in the world. Such people look for perfection in everything, and they take their standards of perfection from the past. They are usually impatient with anyone who is bra ve enough to experiment with new or to express himself or the age in materials original ways. It is, of course, true that many artists do not succeed in their work and instead produce wor ks that can only be considered as failures. If the work of art is a painting, the art ist’s failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untru e to say, as some people do, that modern architecture is nothing.
We can’t judge every modern building by the standards of the ancient time, even though we a dmire the ancient buildings. Technologically, the modern buildings are more advanced. The mo dern architect knows he should learn from the ancient works, but with his greater resources of knowledge and materials, he will never be content to imitate the past. He is too proud to do that.
76. Some people hate everything that is modern because _______.
A. they are aged
B. they find it hard to accept modern things
C. they take their standards of perfection from the Greek
D. they look at things by the standards of the past
