问题补充：
It is good to keep animals in zoos. Zoos are places for people to see many different kinds of animals from all over the world. Without zoos, most people would never see a real tiger or bear. Secondly, zoos look after the animals very well. The animals are always given food and cleaned on time. In the wild, it is not always possible for an animal to find food, so sometimes it goes hungry. Thirdly, zoos protect the animals. They offer them safe place to live in. In the wild, some kinds of animals are in danger of becoming extinct （灭绝).But zoos give these animals a chance to live. Without zoos, there would be fewer kinds of animals in the world.
However, some people think it is unnatural (非自然的) and unfair（不公平的） to keep wild（野生的） animals in cages. Most animals are kept in cages that are too small for them. The animals such as bears and tigers always look sad in cages. Wild animals should look for their own food. Anyone would not feel happy if he isn allowed (允许) to go outside his home and animals don like it either.

答案：
(答案→)F
解析：短文大意：把动物关在动物园里就好了。动物园是人们从世界各地看到许多不同种类的动物的地方。没有动物园，大多数人永远不会看到一个真正的老虎或熊。其次，动物园的动物照顾得很好。第三，动物园保护动物。没有动物园，世界上也就会少很多动物。然而，一些人认为的野生动物呆在笼子里是不自然的和不公平的。
【小题1】细节理解题。根据常识可知狗是一种宠物，不到动物园照样能见到，所以判断为F 。
【小题2】细节理解题。根据第二段第三句The animals such as bears and tigers always look sad in cages.可知该判断为 F。
【小题3】细节理解题。根据常识在野外动物自己觅食，所以判断为T。
【小题4】细节理解题。根据最后一句Anyone would not feel happy if he isn allowed (允许) to go outside his home and animals don like it either.可知该判断为F。
【小题5】细节理解题。根据短文可知作者并不能确信动物呆在动物园是否更好，所以判断为T。
