[2017·山西晋中摸底]

For many years，machines have been doing work that people once did，including some difficult jobs.Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots.But there is another area where they may soon take jobs traditionally held by human beings，the restaurant industry.

Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California.A team from South Korea and its robot，called DRCC-Hubo，won first place in the competition.The second and third place winners were from the United States.The robots were required to drive a vehicle，climb up steps and do mechanical work.Such activities are easy for humans to perform，but more difficult for machines.Not all of the competitors were successful.The failures showed how difficult it is to design effective walking machines.

Akihiro Suzuki works at Yaskawa Electric，a company that develops robots.He says robots cannot do everything a human can，but they are able to work without becoming tired.He says robots cannot taste food，change beating levels or seasonings to get

the best flavor(风味)．But he says if a food can be easily prepared，a robot can repeat the same movement to reproduce the same meal.

One Japanese woman who saw the robots working wanted to bring them home.Masayo Mori says she would like to have a husband who could work like a robot.Suzumo Machinery showed its sushi(寿司) maker robot.It performs the often difficult work of wrapping the popular Japanese food.Hiroshi Monden is an official with the company.He says people all over the world now eat sushi，but there are not enough skilled workers to prepare it.He says his machine can help anyone make sushi.

1．In Paragraph 1，the author tells us________. A．robots just do difficult jobs B．robots are sometimes dangerous C．robots are widely used in our life D．robots are gradually replacing humans

2．Why did some teams fail at the DARPA Robotic Challenge Finals? A．Their robots cannot be applied at home. B．Preparing food is really difficult for robots. C．Their robots can just repeat the same movement. D．They failed to design effective walking robots. 3．We can infer from the last paragraph that________. A．Japanese men are lazy B．robots are popular in Japan C．Japan has advanced high technology

D．robots usually take the job of making sushi in Japan 4．In which column can we probably see the text? A．Education. C．Health.

B．Culture. D．Science.

答案：[解题导语] 这是一篇说明文。主要介绍了机器人的用途、机器人竞赛、制作以及机器人在生活中的使用。

1．C 解析：段落大意题。由第一段：For many years，machines have been doing work that people once did，including some difficult jobs. Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings，the restaurant industry.可知机器人应用在很多领域，包括搜救工作以及即将承担餐馆中的工作等，故此段的主要目的是告诉我们机器人在

日常生活中被广泛使用。

2．D 解析：细节理解题。由第二段尾句：The failures showed how difficult it is to design effective walking machines.可知，一些参赛团队失败的原因是不能设计有效的步行机器人。

3．B 解析：推理判断题。由最后一段第一、二、三句：One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery showed its sushi(寿司) maker robot.可知，一位日本妇女见到正在工作的机器人想将之带回家去，Masayo Mori说她想要一个像机器人一样工作的丈夫，以及后面提到的日本公司用机器人做寿司等可推断，机器人在日本是非常受欢迎的。

4．D 解析：推理判断题。纵览全文可知，本文主要介绍了机器人的用途、机器人竞赛、制作，以及机器人在生活中的使用，这种主题应该出现在科学专栏里。
