Question

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 and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
Until now, even the most advanced (先進(jìn)的) robot was almost certain to break down when it was damaged (毀壞). 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(dòng)機(jī)) 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.”
【小題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.

【小題2】The new technology(技術(shù)) allows the robot to        .

A．keep working after being damaged

B．tell people where it is

C．do house work for humans

D．remember a lot of information

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

A．sensors

B．robots

C．scientists

D．a(chǎn)rms and legs

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

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

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

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

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

解析試題分析：這篇文章講述了為了解決機(jī)器人一旦被損壞就不能工作的問(wèn)題，科學(xué)家給機(jī)器人里面放了八個(gè)發(fā)動(dòng)機(jī)和兩個(gè)傳感器，這個(gè)新的技術(shù)還能幫助科學(xué)家給人們創(chuàng)造出更好的假肢。
【小題1】細(xì)節(jié)題。根據(jù)文章That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed. 可知，當(dāng)機(jī)器人被毀壞了就很容易發(fā)生故障，是因?yàn)槿绻麢C(jī)器人改變了，電腦就不能工作了。故選D
【小題2】細(xì)節(jié)題。根據(jù)文章To deal with this problem, the scientists put eight motors (發(fā)動(dòng)機(jī)) 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(jī)器人被損害時(shí)不能工作的這個(gè)問(wèn)題。故選A
【小題3】推斷題。根據(jù)文章It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them.機(jī)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D
【小題4】細(xì)節(jié)題。根據(jù)文章第三段可知，傳感器能夠幫助電腦了解機(jī)器人的情況。故選B
