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.

Answer 1

小題1:A
小題2:B
小題3:A
小題4:C

試題分析：文章介紹了一種新型的類人機器人，介紹了她的外觀，功能和設(shè)計的過程，特別指出這種機器人有象人一樣的手指，可以做很多人可以做的事情，而且，在一些危險的情況，她也可以發(fā)揮作用。
小題1:猜詞題：從第二段的句子：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. 可知機器人的每個手指上都有個小馬達(dá)，能產(chǎn)生20磅的握力，足以在操作員的指導(dǎo)下拆掉炸彈。所以選A
小題2:細(xì)節(jié)題：從第二段的句子：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, .
可知這個機器人是類人機器人，有象人一樣的長膀子和手，選B
小題3:細(xì)節(jié)題：從第三段的句子："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. "可知這個項目的目的是開發(fā)具有人手所有功能的假肢，使之能像人手那樣做復(fù)雜的動作。所以是想讓prosthetic arms有自然的手的功能，選A。
小題4:推理題：從最后一段的句子：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 認(rèn)為這種類人機器人可以用在危險的情況下，選C
