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(挨打) 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(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 housework for humans

B．keep working after being damaged

C．remember a lot of information

D．tell people where it is

3.The underline 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.

 

Answer 1

【答案】

1.D

2.B

3.C

4.C

【解析】

試題分析：這篇短文主要介紹了當今最先進的機器人，他們能夠在被毀壞之后，還能繼續(xù)工作。

1.根據短文第三段描述，可知選D。

2.根據短文倒數第二段描述，可知新技術能是機器人在毀壞后還能繼續(xù)工作，故選B。

3.聯(lián)系前文It may someday help scientists create better artificial(假的) arms and legs 描述，可知此處指的是機器人的手腳，故選C。

4.根據短文倒數第二段It might also help scientists understand how people and animals figure out their own sense of place in space.描述，可知選C。

考點：關于機器人的科普性說明文閱讀

點評：本文中長句較多，一時很難讀懂句子含義，注意多讀幾遍，不要強求非得理解一詞一句的含義，能把握文章大意就行。然后帶著問題閱讀短文，一般就能順利找出答題依據。對于不能直接找到根據的問題注意聯(lián)系上下文，根據短文中心總結出正確答案。
