They don’t have enough time to relax or to stay with their family. Work hours are different from one country to another. In France, people spend about 1,646 hours a year at work. In Japan, however, people work about 2,159 hours a year. That means a Japanese worker works 513 more hours a year than a French worker. Why do people work so many hours? Some people work extra hours because they want to make more money. However, many companies don’t pay overtime. Their workers don’t get more pay for more work. Some people think it’s their duty to work more hours. Some are afraid of losing their jobs if they don’t work more hours. Many people say that their vacations are too short. In France, people get five weeks of paid vacation a year. In Germany, they get four to six weeks, and in the United States, two weeks. One study shows fewer than half of workers use all their vacation days. In Great Britain, there is a saying, “All work and no play makes Jack a dull (迟钝的) boy.” If that is true, there must be a lot of dull people in the world. 21．A Japanese worker works ________ more hours a year than a French one. A．513 B．1,646 C．2,159 D．3,805 22．People in ________ get only two weeks of paid vacation a year.

D．There are a lot of dull people in the world. 【答案】21．A 22．C 23．C 24．A 【导语】这是一篇说明文。本文叙述了不同的国家人们的工作时间不同。一个日本工人比一个法国人一年多工作513个小时。人们之所以工作那么多时间，是因为他们想多挣钱，或者认为是职责所在，或者是怕失业。不同的国家人们的假期长短不同。 21．细节理解题。根据第二段中“That means a Japanese worker works 513 more hours a year than a French worker. (那意味着一名日本工人每年的工作时长比一名法国工人多513个小时。)”可知，一名日本工人每年的工作时长比一名法国工人多513个小时。故选A。 22．细节理解题。根据第四段中“In Germany, they get four to six weeks, and in the United States, two weeks. (在德国，他们有四到六周的带薪休假时间，而在美国，有两周的带薪休假时间。)”可知，在美国，人们一年只有两周的带薪休假时间。故选C。 23．细节理解题。根据第三段中“However, many companies don’t pay overtime. Their workers don’t get more pay for more work. (然而，许多公司并不支付加班费。他们的员工并不会因为工作量增加而获得更多报酬。)”可知，并非所有公司都会为员工的额外工作量支付报酬。故选C。 24．推理判断题。根据第三段中“Some people work extra hours because they want to make more money. However, many companies don’t pay overtime ... Some are afraid of losing their jobs if they don’t work more hours. (有些人加班是因为他们想挣更多的钱。然而，许多公司并不支付加班费……有些人担心如果不加班就会丢掉工作。)”可推断，许多工人不得不长时间工作。故选A。 三、补全对话（共5小题，每小题2分，共10分） 根据对话内容，从文后选择恰当的选项补全对话，其中有两项多余。 A: Hi, Li Ming How was your summer vacation?
