问题    The science of wildlife management is actually quite new. It is the third major phase of the original conservation movement. The first phase involved the preservation of wildlife through laws and hunting regulations. This phase was a reaction against the terrible destruction of many wild creatures. The second phase involved the control of certain birds and animals that were preying on other wildlife and causing their decline.
   However, the first two phases of the conservation movement had serious limitations. The new laws allowed certain animals to increase so much that they actually "ate up" their habitat. Many of them starved to death because the land simply could not provide for them all. Something had to be done. This is how careful wildlife management came into being.
   One of the chief concerns of wildlife management is the protection and improvement of the natural habitat so that animals have enough food and water to survive. Wildlife management involves care of the soil to produce good vegetation. It involves care of plants and bushes, not only as a source of food, but also as protection. Animals needs cover to hide from their natural enemies and to raise their young safely.
   Just as crops are harvested, wildlife too must sometimes be "harvested". By allowing limited hunting and fishing, good management can control certain species that threaten to overpopulate their habitat.
   Another major part of the wildlife management is the increasing of certain species by artificial means. Some creatures, like the whooping crane, were brought back from the edge of extinction in this way. In order to save these species, members of wildlife teams have reared the young in the safety of research stations.
Which of the following statements is TRUE according to the passage?
选项 A、The problem of wildlife conservation is quite new.
B、There have been three phases in the wildlife conservation movement.
C、In the second phase, certain animals and birds were controlled because they were harmful to humans.
D、Plants have nothing to do with animals but supply food for them.
答案B
解析 从第一段第一句“The science of wild life management is actually quite new”，可知[A]是非真实的；从第一段最后一句话，可知[C]是非真实的。控制动物的数量的原因是“because they were preying on other wildlife”，而不是“harmful to humans”从第三段，便可知“plants and bushes not only as a source of food，but also as protection”，所以[D]也是非真实的，作者在文中第一段就讲了野生动物保护经历三个阶段，因此[B]是真实的，是正确答案。
