The United States has many different kinds of climates（氣候）. On the northwest coast（海岸）, the temperature changes very little between summer and winter, but the north central（中部的）states have a very different kind of climate. In those states, people wear light clothes in summer, and they need heavy woolen clothes in winter.

    In the southwest coast, the climate is rainy and warm during the winter, but the summer is dry and hot.

    In the northeast of the United States, summer temperatures are very different from winter temperatures. Summer is usually hot, and winter is usually cold. Spring temperatures are warm, and fall temperatures are cool.

    Years ago, people in the cold parts of the United States didn’t often get fresh （新鮮的）vegetables and fresh fruits during the summer. Today, however（然而），trucks and trains carry fruits and vegetables very quickly to all parts of the United States. In this way, Americans “send their climates” to people in other states.

　　　　　　　　　　　　　　　　　　　　　　　 The World’s Water Shortage

　 The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly 70 percent（百分比）of the earth’s surface is covered with water. But about 97 percent of this huge amount is sea water, or salt water. Man can only drink and use the other 3 percent－the fresh water from rivers, lakes, underground, and other sources（資源）. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers（冰川）. Even worse, some of it has been polluted.

　 However, as things stand today, this small amount of fresh water is still enough for us. But our need for water is increasing（增加）rapidly－almost day by day. Only if we take steps to deal with this problem now can we avoid（避免）a severe（嚴(yán)重的）worldwide water shortage later on.

　 We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways of reusing it.

　 Today in most large cities, water is used only once and then sent out into a sewer system（下水道）. From there it returns to the sea or runs into underground storage tanks. But it is possible to pipe used water to a purifying（凈化）plant. There it can be treated with chemicals so that it can be used again, just as if it were fresh from a spring.

　 But even if every large city purified and reused its water, we still would not have enough. All we’d have to do to make use of the vast reserves（貯備）of sea water in the world is to remove the salt.

　 If we take these steps we’ll be in no danger of drying up.

　 D. We should take steps to deal with the water shortage problem.

3. To reuse water, we should __________.

　 A. treat it with chemicals

　 B. use it only once

　 D. make it flow into underground tanks

4. In order to have enough water, we should also make use of _________.

　 A. icebergs and glaciers

　 B. sea water

　 C. rivers and lake

　 D. underground water

5. In the passage, the writer tells us ________.

Suppose （假定）every person on Earth ate only one kind of food. And maybe one year that food couldn’t　 1 . If that happened, man would soon　 2 .

　 Luckily, man doesn’t　 3　 that problem. But another animal may. The animal is the giant （巨大的）panda, one of the world’s most-loved animals.

　 Dr Thomas Soderstrom, a scientist, has　 4　 for the first time that the bamboo（竹子）the giant pandas eat is dying. As a result, many of the pandas are also dying of being　 5 . Scientists estimate （估計(jì)）that so far more than 140 giant pandas have died. This number may be　 6　 one-quarter of the world’s giant panda population. Between 400 and 1000 giant pandas are　 7　 to live in mountains.

　 Giant pandas were once more　 8　 all over many parts of Asia（亞洲）. Now they are only in small parts of China.

　 Can the wild pandas be　 9 ?

　 The scientists want to find out more about the animals’ food. They want to see whether the pandas are able to　 10　 their food while the bamboo is dying.

　 Chinese scientists are trying to raise（飼養(yǎng)）more pandas in zoos. The first baby panda was born in the Beijing Zoo in the fall of 1978.
