Question

1. They take their dogs for walks, give them good food and medical care. However, dogs without owners to care for them lead a different kind of life. The expression, lead a dog’s life, describes a person who has an unhappy existence.

When we say we live in a dog-eat-dog world. 2. A person has to work hard like a dog to be successful. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.

Junkyard dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. 4.

【解析】

本文是一篇说明文，狗是人类的好朋友，在人类的语言里也有很多与狗相关的短语，文章介绍了一些与狗有关系的短语及句子。

1.横线后句“They take their dogs for walks, give them good food and medical care.”告诉我们人类对狗很好，把它们照顾的也很好。C项“People love dogs and treat them well.”符合上下文语境，所以选择C项。

2.横线后句“A person has to work hard like a dog to be successful.”告诉我们人们必须要非常努力才可以成功。人类社会和狗一样，都要通过竞争获得某个东西。G项“That means many people are competing for the same things, like good jobs.”符合上下文语境，所以选择G项。

3.根据横线后两句“Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new skills and will not change the way they do things”可知有些人认为老人不会学会新的技巧，也不会改变做事的方法。句中的yet是关键词，说明前句内容与后句相反，F项“To be successful, people often have to learn new skills.”阐述了要想成功，人们必须学会新的技巧。本句符合上下文语境，故F项正确。

4.横线前句“However, sometimes a person who appears to be mean and threatening is really not so bad”告诉我们有时候表面似乎很危险的人实际上并不是很坏。这类人可以被比喻成为“bark is worse than bite”，D项符合上下文语境，所以选择D项。

5.本段的主题是“Dog expressions are also used to describe the weather.”运用与狗有关的短语来描述天气，B项“A rainstorm may cool the weather.”符合语境，所以选择B项。
