Robots are smart. With their puter 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 weights 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 name, their parents’ names, and what each child knows and needs to know. In addition, 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 puter brain puts the child’s voice and number together. He identifies the child with no mistakes.
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.

(答案→)D
解析：本文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，可以送邮件等等，像这样的机器人美国有250个。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。
【小题1】D主旨大意题。文章开头提出Robots are smart. With their puter brains, they help people work in dangerous places or do difficult jobs.然后举了两个机器人的例子，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。
【小题2】A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，从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。
【小题3】D词意猜测题。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。
【小题4】B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。
