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(技術) 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

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

A．sensors           B．robots            C．scientists          D．arms and legs

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.

2.A

3.D

4.B

【解析】

試題分析：這篇文章講述了為了解決機器人一旦被損壞就不能工作的問題，科學家給機器人里面放了八個發動機和兩個傳感器，這個新的技術還能幫助科學家給人們創造出更好的假肢。

1.細節題。根據文章That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed. 可知，當機器人被毀壞了就很容易發生故障，是因為如果機器人改變了，電腦就不能工作了。故選D

2.細節題。根據文章To deal with this problem, the scientists put eight motors (發動機) and two sensors (傳感器) that read how the machine is working.可知，新的技術就是解決了機器人被損害時不能工作的這個問題。故選A

3.推斷題。根據文章It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them.機器人有一天能夠幫助科學家發明出更好的假肢，幫助那些失去了胳膊和腿的人重新獲得自由。可知，them的意思是arms and legs。故選D

4.細節題。根據文章第三段可知，傳感器能夠幫助電腦了解機器人的情況。故選B

考點：科普類說明文

點評：本文的文章短小精煉，對于此類文章首先必須對每句話都要認真地閱讀理解。初中的閱讀絕大多數是細節題，考察學生信息的把握能力。對于細節題，學生在理解全文的基礎上要對題目中關鍵字在文章中迅速定位，找到相對應的出處，再仔細對比找出答案。
