试题分析：句意：手里拿着一本旧书的女孩是我的最好的朋友Amy。第一空表示特指手里拿书的女孩，而不是别人；第二空表示一本，是泛指，故用不定冠词，因为old是以元音音素开头的单词所以应该用an,故选D。
考点: 考查冠词的用法。
Bats are amazing animals. There are many kinds of them. Most bats are black or grey in colour. And they have wings, too. Many people believed that bats couldn’t see. In fact, Bats can always find their way around very well. Usually, bats live in caves and trees. They can fly to their homes from far away. Some scientists said, “Bats can see with their ears.” Is it right? Most bats make a sound. The sound is too low for our ears to hear. They screech（尖叫） when they move around, and the echoes（回声）of these cries come back to their ears. In this way, they are able to tell where walls and other things are. Bats go out to eat at night. In the daytime they hang close together in their caves, trees or other dark places. Only when evening comes，they begin to come out and look for food, In the morning they come home to sleep until the next night. Some people think of bats as bad animals. In fact, they are very useful animals. Most of them catch bad insects（昆虫）for food. Some bats eat flowers and fruit as well.
