Question

Researches at Johns  Hopkins University's. Applied Physics laboratory  ( APL)  in Laurel , Maryland have designed a new human-like robot, Its name is Robo Sally. The machine can be controlled from a distance and can he used to do work that is dangerous for human beings.

       Roho Sally has two long arms with human-like hands. She can use her fingers to pick up  small objects .examine them in detail and do most things that human hands can do Each finger  contains a tiny motor capable of squeezing 20 pounds of pinch foree ,.enough to defuse a bomb  under the direction of an operator. She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, .

       Mike McLoughlin is the main investigator for the Applied Physics Laboratory's Prosthetics  Program. "The purpose of that program is to develop prosthetic arms that have all the capability  of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. "

       It was a difficult job. Mr. McLoughlin says the device had to have many small motors to。 have the ability to do what a human hand does; It  also needs to have human-like strength. The  thumb was especially difficult because it permits the hand .to hold objects. And everything had.   to fit into a space about the size of a human hand.

      The next problem  .he says .was to figure out how to control the artificial hand. " So we had   to figure out how to make the connection between the brain and this arm.

       For search-and-rescue duties.Roho Sally will be operated by a human being using a wire- less machine that is far from the robot. The operator will also wear special gloves and glasses.  The glasses permit the operator to see the robot's hands .even though they are far away.

      Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. He says the technology is  not ready for everyday application .but he predicts that within five years we will see some won-  derful improvements.

1.The underlined word " defuse"  in Paragraph 2 is closest in meaning to "_________".

【解析】

试题分析：文章介绍了一种新型的类人机器人，介绍了她的外观，功能和设计的过程，特别指出这种机器人有象人一样的手指，可以做很多人可以做的事情，而且，在一些危险的情况，她也可以发挥作用。

1.猜词题：从第二段的句子：Each finger contains a tiny motor capable of squeezing 20 pounds of pinch force ,.enough to defuse a bomb under the direction of an operator. 可知机器人的每个手指上都有个小马达，能产生20磅的握力，足以在操作员的指导下拆掉炸弹。所以选A

2.细节题：从第二段的句子：Roho Sally has two long arms with human-like hands.和 She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, .

可知这个机器人是类人机器人，有象人一样的长膀子和手，选B

3.细节题：从第三段的句子："The purpose of that program is to develop prosthetic arms that have all the capability of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. "可知这个项目的目的是开发具有人手所有功能的假肢，使之能像人手那样做复杂的动作。所以是想让prosthetic arms有自然的手的功能，选A。

4.推理题：从最后一段的句子：Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. 可知Mr. McLoughlin 认为这种类人机器人可以用在危险的情况下，选C
