问题 What is the concern of ordinary people about the "Greenhouse Effect"?
  
If the earth gets hotter in the new century, what will happen to animals and the plants which animals depend on for survival7 The question offers another way of looking at the "Greenhouse Effect". People have talked about the general problem of "Global Warming" for some time.  But they were usually worried about things like whether to buy a home on the coast. Biologists and other scientists turn their attention to plants and animals at an important meeting that took place last October. They reviewed evidence that plants and animals are sensitive to climate. Since the Ice Age ended ten thousand years ago and warmer temperatures returned to the northern latitudes, many species have migrated north. If the predictions about the Greenhouse are correct, temperatures will rise by the same amount in the next one hundred years as they did in the past ten thousand. Will animals and plants be able to adapt that quickly to change in the environment.’? Many won’t. Certain species will probably become very rare. Experts say plants under climate stress will be very open to disease and fire.  Forest fires may become more common. That, in turn, may harm animals that depend on the trees for food and for shelter. Any preserves we set up to protect endangered species may become useless as the species are forced to migrate along with their natural homes. Change is a part of life, but rapid change, says scientist George Wood well, is the enemy of life.

选项 A、They will gradually die out.
B、They will be able to survive in the preserves.
C、They will have to migrate to find new homes.
D、They will face extinction without artificial reproduction.

答案A

解析 题干问:“根据文章的意思,将要灭绝的物种将怎么样?”材料中说“Any preserves we set up to protect endangered species may become useless as the species are forced to migrate along with their natural homes.”这句话的意思是由于我们所保护的那些将要灭绝的物种将随着自然家园的改变而迁移,那么人们建立的保护区也许会失败,言外之意,是说那些将要灭绝的物种就真的会灭绝。所以本题的
