In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal(木炭) or selling wood to the townsman（城市居民）. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.This does not only mean th at the villager’s sons and grandsons have fewer trees. The results are even more serious. For where there are trees their roots break the soil up—allowing the rain to sink in and also hold the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.( ) 1. The purpose that the writer wrote this article is to ______.A. tell people the use of woodB. tell people the function of tree rootsC. warn that man mustn’t destroy forests any moreD. explain how trees help to prevent drought and floods( ) 2. In the writer’s opinion,_____, or the forests will slowly disappear.A. measures must be takenB. people shouldn’t draw benefit from the treeC. government must realize the serious resultsD. unless trees never be cut down( ) 3. According to the article we know it is _____ to prevent the forests from slowly disappearing.A. necessary but impossibleB. necessary but difficultC. impossible and unimportantD. difficult and impossible( ) 4. In the last two paragraphs the writer wanted to make it clear that _____ .A. where there are no trees, the soil becomes poor but softB. where there are many trees, there are more floodsC. where there are no trees, the land might become desert slowlyD. floods will make the land become desertBExcused from recycling because you live in a high rise with a rubbish chute(垃圾运送槽)? You won’t be long. Miami’s Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too.In Shantzis’s Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables glass, plastic, paper, metal and other rubbish to go into separate boxes.The system is controlled from a board fixed next to the chute door. The board has a button for each class of recycling materials (as well as for unrecyclables). At the press of a button, a microcomputer locks all other chute doors and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the non-recyclables.Sorting recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted. Shantzis believes his system could help recycled materials become more cost-effective.( )5. The purpose in writing this text is ______.A. to introduce a recycling system for high risesB. to encourage people to recycle their rubbishC. to describe the use of computer technology in recyclingD. to explain the need for rubbish collection in high rises( )6.

Before dropping rubbish into the chute you have to ______.A. lock the other floors’ chute doorsB. press the correct buttonC. check if the container is fullD. break up the rubbish( )8. The biggest advantage of this new system is that ______.A. it makes better use of the existing recovery equipmentB. it saves time and spaceC. it saves money for people living in high risesD. it reduces the cost of recycling四语法填空题10分As the third _____ river in the world, the health of the Yangtze River has raised _ ____ both China and abroad.But the rapid development and an increase in _____ cause the pollution .
