4 Translate the following sentences into English.

1. Statistics show that China has a total amount of

2.8 trillion cubic meters of water resources, second only to Brazil, Russia and Canada, ranking the fourth (to be updated) in the world. But when divided by 1.3 billion, our average per-capita share of water resources only amounts to about one quarter of the world’s average.

2. We have always been heavily burdened with the problem of water shortage. It is said that of the 661 large and medium-sized cities nationwide, about two-thirds are suffering from an acute shortage of water. Beijing is a good example in point. It not only lacks surface water, even its underground water table is dangerously low. It is reported to have dropped by 90 meters. Some scholars suggest we move our capital to some other place. This is of course unfeasible/unrealistic, but the message is clear.

3. Our water resources first of all are not evenly distributed in time or space. They are either too much, causing floods, or too little, causing droughts.

4. In spite of the impressive progress we have achieved in the past years, we are still far from effectively harnessing our rivers, lakes and reservoirs. Soil erosion and desertification are increasingly threatening our economy and people’s life. Many of our rivers no longer flow to the sea. In 1998, the Yellow River failed to have enough water to flow to the sea for 212 days.

5. Traditionally our water resources have mainly been used to irrigate land but, in recent years, demands on water for industrial and domestic use have also been sharply

on the rise. They have seriously outgrown supplies.

6. Today our scarce water resources are becoming even scarcer because a lot of water is being wasted on capacious baths, power showers, flush lavatories, and golf rinks. Moreover, a lot of water is being polluted.

7. These two rivers both have their headwater in the country. It therefore makes water an issue for potential serious dispute between the two countries.

8. In recent years, we have pinned great hopes on the projects to divert water form the south to the north, hoping that it will once and for all solve our flood problem in the south and the drought problem in the north. But there are scholars whose opinions differ. They warn us that the immunity of the Yangtze to droughts cannot be taken for granted.

6 Translate the following sentences, paying attention to the use of hyperbole and its understatement

1. 我有一千条理由相信，下次世界大战将因争水而发生。

2. 你若发现自己一个人夜游中央公园，那就赶快跑到狮子洞里去，在那里你会更安全些。

3. 我最近吃了成吨的抗生素。

4. 我们上那家小饭店去吧。那里的菜味道还可以。

5. 我不该喝酒，因为我要开车回家。好吧，就喝一丁点。

6. 花销没有上限，想花多少就花多少。

7. 别反应过度/小题大做。这只不过是一点小误会。

8. 大家都知道她是本活百科全书。第一次见她我就感觉到这将是美好友谊的开始。

9. 在过去的两天里她没合过眼，完全被如山般堆积的文书工作占据了。

10. 当那个男子说他已深深爱上了他，她的反应是轻轻地说了声她对他也并不是完全无动于衷。

11. 真理还在穿鞋的时候，谎言已经跑完了半个地球。
