Statistics show that China has a total amount of 2.8 trillion cubic meters of water resource, 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 resource only amounts to about one quarter of the worlds average.2. We have always been heavily burden with the problem of water shortage. It is said that the 661 large and medium-sized cities nationwide, about two-thirds are suffering from acute shortage of water. Beijing is a good example in point. It not only lacks surface water, even its underground water 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 peoples 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 power showers, flush lavatories, and golf rinks. Moreover, a lot of water 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 from the south to the north, hopping 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 immunity of the Yangtze to droughts cannot be taken for granted.1 with better medical care, my grandfather could have lived to eighty.2 even at a gunpoint I wouldnt renounce my beliefs.3 Further delay would cause us even greater loss.4. But for the seatbelt, she would have been severely injured in the acctident.5 A man without a strong sense of justice wouldnt have brought the matter up.6 Without an experienced guide like her, we might have been trapped in the jungle.7 I wonder how many of us would have done the same in his position8 With a more sophisticated computer, we would have completed the project much sooner.9 Without a
