【听力材料】
When you take a walk in any of the cities in the West, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reasons why people keep a dog have changed. [32]In the old days people used to train dogs to protect themselves against attacks by other beasts. And later they came to realize that [33]a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission. But now people in the city need not protect themselves against attacks of animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery. [34]But the most important reason is for companionship. For a child, a dog is his best friend when he has no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has [35]changed from protection to friendship.
Questions 32 to 35 are based on the passage you have just heard.
32. According to the passage, what were dogs trained for in the past?
正确答案：A
解析：短文提到，“过去人们养狗是为了保护自己不受其他野兽的侵袭”。故A（防范其他动物）正确。
33. Why were dogs used for hunting?
正确答案：D
解析：原文说，狗愿意听主人的话；并举例说，打猎时，若无主人允许，狗不会吃它抓到的猎物。故D正确。
34. What is the most important reason for people in the city to keep dogs now?
正确答案：A
解析：短文提到，“如今，城里人养狗最重要的原因是做伴”，故A正确。
35. What is the main idea of this passage?
正确答案：D
解析：整篇文章讲养狗的目的和好处，故D正确。
