b. Bats sleep in many different kinds of places during the day.
答案
b
解析
The passage first introduces that bats sleep upside down in caves during the day, and then mentions that they also sleep in trees, old buildings, and even under bridges, and gives an example of a large number of bats sleeping under a bridge in Austin, Texas. The key point is to emphasize that bats sleep in many different places during the day, and the example in Austin is just a specific case to support this key point. So the main idea of the passage is that bats sleep in many different kinds of places during the day.
B
Dogs and wolves are part of the same animal family. They both have strong senses of smell and are loyal to their packs. But dogs and wolves are quite different when it comes to people. Dogs are used to living with people and get along well with them. In fact, dogs have been called “man’s best friend”. Wolves, on the other hand, cannot live with humans. Wolves prefer to live in the wild, where they can hunt for their food. Clearly, dogs belong with people, while wolves do not.
What is the main idea of the passage?
a. Dogs are better suited to living with people than wolves are.
b. Wolves and dogs are members of the same animal family, so they have many things in common.

答案
a
解析
首先，文章开头提到狗和狼同属一个动物家族且有共同之处，如嗅觉灵敏、对群体忠诚。但随后用“but”转折，重点阐述两者在与人相处方面的不同：狗习惯与人生活且相处融洽，被称为“人类最好的朋友”；而狼不能与人类生活，更喜欢在野外捕猎。最后一句“Clearly, dogs belong with people, while wolves do not.”总结了核心观点，即狗比狼更适合与人生活。选项b只提到了相同点，未体现重点的不同之处及结论，选项a符合主旨。
