Americans use many expressions with the word “dog”. People in the United States love their dogs and treat them well. 51 . However, dogs without owners to care for them lead a different kind of life. The expression, to lead a dog's life, describes a person who has an unhappy life.
Some people say we live in a dog-eat-dog world. 52 . They say that to be succe
ssful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.
53 . This means that every person enjoys a successful period during his or her life. To be succ
essful, people often have to learn new skills. 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 things and will not change the way they do things.
54 . People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. But mean dogs are often used to guard this property(财产). They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening(威胁) is really not so bad. We say his bark is worse than his bite.

阅读下面这首唐诗,完成11~12题。
长安秋望
赵嘏①
云物②凄清拂曙流,汉家宫阙动高秋。
残星几点雁横塞,长笛一声人倚楼。
紫艳半开篱菊静,红衣落尽渚莲愁。
鲈鱼正美不归去,空戴南冠③学楚囚。
注:①此诗歌是赵嘏举进士不第后客居长安时所作。②云物:云雾。③南冠:《左传》记载晋侯观于军府,见钟仪,问之曰:“南冠而絷者,谁也?”有司对曰:“郑人所献楚囚也。”后以南冠、楚囚为囚徒的代称。
