Question

【题目】根据短文理解，选择正确答案。
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 (先进的) 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 (发动机) and two sensors (传感器) 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.

Answer 1

【答案】
（1）D
（2）B
（3）C
（4）C
【解析】短文大意：这篇短文主要讲述了一种新型的机器人，一种新技术将使得机器人在损坏后也能继续工作。

（1）D 细节理解题。根据短文“Until now, even the most advanced (先进的) robot was almost certain to break down when it was damaged.” 描述，可知是因为当机器人改变时，电脑就不工作了。故选D。

（2）B 细节理解题。根据短文“For the first time, scientists have made a robot that can take a beating(挨打) and keep on going.”描述，可知新技术将使得机器人在受到损坏后也能继续工作。故选B。

（3）C细节理解题。根据短文“It may someday help scientists create better artificial (假的) arms and legs ”描述，可知这个人称代词指代的是前文提到的假肢，故选C。

（4）C 细节理解题。根据短文“and two sensors (传感器) that read how the machine is working.” 描述，可知传感器是用来感知机器人的状况的。故选C。
