Statistics show that China has a total amount of2.8 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 sharplyon 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 understatement1. 我有一千条理由相信，下次世界大战将因争水而发生。
