Passage Four
The atmosphere and oceans are not the only parts of the environment being damaged. Rain forests are being quickly destroyed as well, and their survival is questionable. E. O. Wilson, a biologist at Harvard, calls the depletion(枯竭、耗尽)of rain forest areas "the greatest extinction since the end of the age of dinosaurs(恐龙)."
Unlike some environmental issues, rain forests' depletion has fortunately received significant public and media's attention. Despite the opposition to the cutting down of rain forests, the problem continues. Every year, Brazil chops down an area of forests the size of the state of Nebraska. In addition to the Amazon's rain forests, many other forests are being cut down as well.: In Indonesia, Zaire, Papua-new Guinea, Malaysia, Burme, the Philippines, Peru, Colombia, Bolivia, and Venezuela, rain forests that were once great have been lost.
According to some estimates, 50 million acres of rain forest are cut down every year. The United Nations says the figure is closer to 17 million acres. The World Wildlife Fund says that every minute,25 to 50 acres are cut down or burnt to the ground.
The world's growing population has been a primary reason of rain forests' destruction. More people need land to live on and wood products to consume. Limiting population growth may be the first in a series of steps that would alleviate the destruction of the rain forests.
48. In the opinion of the author, ______are being destroyed terribly at present.
A. the oceans
B. the atmosphere
C. the rain forests
D. all the above

问答题Does it always matter if the “real world” is not being practiced in the classroom? Why or why not?正确答案： It is always desirable to practice language in the classroom as it is used in the real world, since students will have to use the target language in real communication outside the classroom. However, it is not always possible to do so because classroom is after all different from the outside world no matter how hard you try to simulate the real world situation. And it is not always necessary to do so. Language teaching is conducted at several stages. At the drilling stage, when the focus is on language form, the “real world” does not have to be practiced. But when the focus is on meaning and students are engaged in communication activities, the “real world” practice does matter much. It is where the students learn to use the target language for real communication, and to use it appropriately.解析： 暂无解析 -

问答题Many parts of the world are losing important natural resources, such as forests, animals, or clean water. Choose one resource that is disappearing and explain why it needs to be saved. Write a composition of about 400 words on the topic.正确答案：
SAVING TREES ON OUR PLANET Many natural resources are being wasted on our planet every day. One of the most important resources we are abusing is our trees. Each year, hundreds of thousands of acres of trees disappear in countries all around the world. In some countries, trees are used for fuel. In other countries, trees are destroyed to build houses and shopping centers. Saving trees has become a major cultural and economical issue in many parts of the world.
Trees are essential to our survival. They are a major part of the process of photosynthesis. Photosynthesis is the process in which green plants use carbon dioxide to produce oxygen, and oxygen is something all of us need. The fewer trees there are, the more this affects our ability to breathe.
In rural areas, farmers have always known how important trees are to soil conservation. This is why you'll usually see trees lining a field. Tree roots help keep the soil in place, and are also a factor in water distribution deep beneath the ground. They help to prevent drought and floods. Unfortunately,in many parts of our country,people haven't realized the importance of trees. They cut them down at will. They are usually too lazy or too careless to plant and look after new trees. As a result, the forests continue to disappear. Where there are no trees the rain falls on the surface, causing floods, and carries away with the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but worthless deserted.
Trees are also important in the development of many medicines. The mainstream medical establishments did not recognize this for many years. However, those who use natural medicines have always known how important trees are. Many drugs come from the leaves of certain trees, along with other herds and plants.
Finally, we should save trees from disappearing because they provide so much pleasure. I think that I shall never see a poem as lovely as a tree, wrote a poet. That is the truth. A tall, stately tree is beautiful to look at, and pleasing to the soul. It is also a great place to find shade on a hot summer's day.
For practical and emotional reasons, we need to preserve our planet's trees.解析：

问答题Practice 10 The momentum is building ahead of next month’s G8 summit in Scotland where the leaders of the world’s richest nations will debate what they can do to help some of the world’s poorest. Africa is the priority and the politicians will discuss reducing the debt burden, ending trade regulations which put the continent’s economy at a disadvantage, and giving more aid. Mark Doyle, who’s reported from Africa for many years, looks at why aid is necessary, and why much of what’s been donated in the past has not worked. All around the edge of Africa-along the coastline, near the continents’ ports—are monuments to exploitation. On the island of Goree, for example, just off the coast of Senegal, there’s: the Slave House. This was the last place many Africans saw before being shipped off to a lifetime of slavery in American or, just as often, to death on the high seas. There are many more places like this dating from the three hundred and fifty years or so of the African slave trade. When people wonder why Africa is so poor, they need look no further for the start of an explanation.正确答案：
【参考译文】
下个月在苏格兰举行的八国峰会上,世界上最富有国家的领导人将会讨论他们能为世界上最贫穷的国家做些什么。而在峰会召开前的一个月这种发展势头就有了征兆。非洲是优先考虑的对象,政客们会讨论减少非洲的债务负担,终止那些束缚非洲经济发展的贸易规则,同时给予更多的经济援助。马克·多伊勒在非洲从事新闻报道多年,他将探讨为什么经济援助是必须的,以及为什么以前的大部分资助没有起到作用。
沿着非洲的边界线——沿着海岸线,靠近大陆的港口——矗立着关于剥削的纪念碑。例如,离塞内加尔海岸线不远处的戈雷岛上就有一个奴隶交易所。这是很多被船只运往远方的非洲人离开故土时所看到的最后一个场景,他们很可能一辈子在美洲做奴隶,或是在途中葬身于汹涌的大海,而这种事情时常发生。
还有很多这样的地方,他们可以一直追溯到350年以前的非洲奴隶交易。当人们纳闷为什么非洲如此贫穷时,他们不再需要其他的解释。解析： 暂无解析 -
