The average American enjoys having pets around, and for good reason. Researchers have discovered that interacting with animals lowers a person's blood pressure. Dogs can offer protection from burglars and unwelcome visitors. Cats can help rid the home of unwanted pests. Little creatures of all shapes and sizes can provide companionship and love. In many cases, having a pet prepares a young couple for the responsibilities of parenthood. Pets even encourage social relationships: They give their owners an appearance of friendliness, and they provide a good topic of conversation.   　　美国人一般都喜欢有宠物为伴，这是有原因的。研究人员发现，与动物为伍能够降低人的血压。狗能防止小偷及不受欢迎的访客。猫能帮忙清除家里讨人厌的害虫和有害的小动物。任何种类及大小的小宠物都能带给人们相伴与爱的感觉。很多时候，拥有一只宠物能帮助年轻夫妻做为人父母责任的准备。宠物甚至有助于人际关系：它们使主人们看起来更友善，并且也带给人们一个交谈的好话题。  
　　Pets are as basic to American culture as hot dogs or apple pie. To Americans, pets are not just property, but a part of the family. After all, pets are people, too.   　　宠物是美国文化中很基本的一部分，就如热狗和苹果派一样。对美国人而言，宠物不仅仅是他们所拥有的一样东西而已，它是家庭的一部分。毕竟，宠物也是「人」啊！liuxuepaper.com
