请教费费43.提的范围问题
43. Zoos have served both as educational resources and as entertainment. Unfortunately, removing animals from their natural habitats to stock the earliest zoos reduced certain species’ populations, endangering their survival. Today most new zoo animals are obtained from captive breeding programs, and many zoos now maintain breeding stocks for continued propagation of various species. This makes possible efforts to reestablish endangered species in the wild. Which one of the following statements is most strongly supported by the information above? (A) Zoos have played an essential role in educating the public about endangered species. (B) Some specimens of endangered species are born and bred in zoos. (C) No zoos exploit wild animals or endanger the survival of species. (D) Nearly all of the animals in zoos today were born in captivity. (E) The main purpose of zoos has shifted from entertainment to education. 答案是B,但是我觉得D好象更好呢?理由是:born in captivity 证明那个captive breeding programs有效。D的all of the animals in zoos可以说是文中的new zoo animals 吧?(这个范围不知道有错吗?)如果说all of the animals in zoos不合new zoo animals 的范围,那 B 的endangered species 也好象不合范围哦。不知道哪里思路不对呢? |
