Question

Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the robot mail carrier, brings mail to a large office building in Washington, D.C. He is one of 250 robot mail carriers in the United States. Mr Leachim, who weighs two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child's pets and hobbies. Mr Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification(识别) number. His computer brain puts the child's voice and number together. He identifies the child with no mistake.

Another advantage is that Mr Leachim is flexible. If the children need more time to do their lessons they can move switches. In this way they can repeat Mr Leachim's lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr Leachim off.

【解析】本文是一篇科普文章，介绍了智能机器人的多种用途。Bobby可以从事人们正常的工作，用作机器人邮递员，是美国250个机器人邮递员之一。而机器人Mr Leachim是有着许多优势的老师，他可以去满足不同孩子的不同需求，而且使用方便。

1.段落大意题。文章短文开头的句子“Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs.”可知，此段通过列举两个机器人的例子，由此可知文章中心是介绍机器人在多方面对人类的帮助，所以D选项正确。

2.细节理解题。文章第一段介绍了机器人老师Mr Leachim的很多优势，结合短文中的句子“what each child knows and needs to know. In addition, he knows each child’s pets and hobbies.”可以推断A选项正确。

3.词意猜测题。A. not strict不严厉的；B. not hard不难的；C. suitable适合的；D. changeable灵活的。从文章最后一段的介绍可知孩子们可以随时听老师的讲课，也可以一遍遍播放老师的讲课内容，由此推断flexible意思是“灵活的”，所以D选项正确。

4.推理判断题。从文章最后一段If the children need more time to do their lessons they can move switches. 和At the end of the lesson the children switch Mr. Leachim off. 可以判断机器人老师是由电操作控制的，故B选项正确。
