Question

【題目】閱讀下面短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back．

Now science fiction has become science fact．For the first time, scientists have made a robot that can take a beating (挨打) and keep on going．Scientists from Cornell University made t he robot, which looks like a spider with four legs．

Until now, even the most advanced (先進的) robot was almost certain to break down when it was damaged． That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed．

To deal with this problem, the scientists put eight motors (發(fā)動機) and two sensors (傳感器) that read how the machine is working．They all give signals to the machine’s software．Using this information, the computer can then figure out the machine’s shape at any moment．

The new technology is a big advance in robot-making, scientists say, and it’s far from scary．It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them．It might also help scientists understand how people and animals figure out their own sense of place in space．

“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US．“With this work, we are nearer to solving this problem．”

【1】Why do robots easily break down when they are damaged?

A． They cannot repair themselves．

B． The computer has changed a lot．

C． They have no computers inside．

D． The computer cannot work if the robot changes．

【2】The new technology allows the robot to _________．

A． do house work for humans

B． keep working after being damaged

C． remember a lot of information

D． tell people where it is

【3】The underlined word “them” in Paragraph 5 refers to ________．

A． sensors

B． robots

C． arms and legs

D． scientists

【4】How do the sensors in the robot work?

A． They can replace the computer when it’s broken．

B． They can find out where the damage comes from．

C． They help the computer learn the robot’s condition．

D． They can send signals to the person who uses the robot．

【5】The passage is probably from____________．

A． an advertisement

B． a tour guide

C． a notice

D． a newspaper

Answer 1

【答案】

【1】D

【2】B

【3】C

【4】C

【5】D

【解析】

【1】細節(jié)理解題 從這句話‘That is because its computer inside simply doesn’t know how to make the machine work after its shape has changeD． ’ 可知，當機器人被毀壞了就很容易發(fā)生故障，是因為如果機器人改變了，電腦就不能工作了。故選D。

【2】細節(jié)理解題 從這句話‘To deal with this problem, the scientists put eight motors (發(fā)動機) and two sensors (傳感器) that read how the machine is working．’可知，新的技術(shù)就是解決了機器人被損害時不能工作的這個問題。故選B。

【3】細節(jié)理解題 從這句話‘it may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them’．機器人有一天能夠幫助科學(xué)家發(fā)明出更好的假肢，幫助那些失去了胳膊和腿的人重新獲得自由�？芍�，them的意思是arms and legs。故選C。

【4】and two sensors (傳感器) that read how the machine is working. 描述，可知傳感器是用來感知機器人的狀況的。故選C。

【5】細節(jié)理解題A． an advertisement 一則廣告 B． a tour guide一個導(dǎo)游 C． a notice 通知D． a newspaper一期報紙 根據(jù)短文介紹，出處來之于報紙較合理。故選D。
