Passage Two
Compared with the robot, the human worker is undoubtedly superior. He is capable of performing a wider variety of work.
Moreover, he is able to adapt his working pattern in order to cope with changing situations which the robot cannot do. On the other hand, the human worker is relatively weak and cannot tolerate work in extreme conditions such as extremely high or low temperatures.
Consequently, we find humans and robots working together in many areas of work. Robots are used to perform dangerous tasks so that their human operators need not risk their lives. To handle harmful radioactive materials, such as uranium (铀), robots in the form of machined arms are used so the human operators can stay from the fatal rays.
Another advantage of the robot is that it never complains about long working hours or that it is boring. It works around the clock and performs equally well in any situation. It needs little servicing and absolutely no holidays. That is why many of them are used to replace human workers for simple and repetitive jobs. The car manufacturers, for example, were amongst the first to use robots to replace workers working on the assembly line. They take over such boring tasks as tightening nuts and screws and spraying paint. Released from these unrewarding tasks, the human worker can be trained for more fulfilling posts, where he can make full use of his ability and get satisfaction from them. The management, on the other hand, will also benefit from these "human pretenders" as they form a new work force which is able to produce more at a lower cost.
Looking to the future, we can expect tomorrow’s robots to be even more "intelligent" than those of today.

A:he likes his job B:he works non-stop C:he is very punctual D:he repairs clocks and watches

第二篇 　　 Shopping at Second-hand Clothing Stores 　　When 33-year-old Pete Barth was in college, shopping at second-hand clothing stores was just something he did - "like changing the tires on his car." He looked at his budget, and decided he could save a lot of money by shopping for clothes at thrift shops. 　　"Even new clothes are fairly disposable (用后即丢掉的) and wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes." 　　Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons for shopping for second-hand clothing. Some people like him, shop to save money. Some shop for a crazy-looking shirt. And some hop as a means of conserving energy and helping the environment. 　　Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said hat, for her, shopping at thrift shops is a way to help the environment. 　　"When my daughter was little, we looked at it as recycling," Akins said. "Also, why ay 30 dollars for a new coat when you can get another one for a lot less?" 　　Akins said that the SA has shops all over the US - "some as big as department stores." All of the clothes are donated (捐赠), and when they have a surplus (盈余), they’ll have "stuff a bag" specials, where customers can fill a grocery sack with clothes for only or 10 dollars. 　　Julia Slocum, 22, points out, however, that the huge amount of second-hand clothing in the US is the result of American wastefulness. 　　I’d say that second-hand stores are the result of our wasteful, materialistic culture," said Slocum, who works for a pro-conservation organization, the Center for a New American Dream. "Thrift shops prevent that waste from going to landfills (垃圾填埋场); they give clothing a second life, provide cheaper clothing for those who can’t afford to buy new ones and generate (生成) income for charities. They also provide a way for the wealthy and middle classes to shed (摆脱) some of the guilt for their level of consumption." Which statement about Barth is NOT true?

A:He is 33 years old now. B:He works at a Goodwill thrift shop. C:He works at a Salvation Army thrift shop. D:He was a college student many years ago.
