Question

【題目】根據(jù)短文理解，選擇正確答案。
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.

Answer 1

【答案】
（1）D
（2）B
（3）C
（4）C
【解析】短文大意：這篇短文主要講述了一種新型的機器人，一種新技術(shù)將使得機器人在損壞后也能繼續(xù)工作。

（1）D 細節(jié)理解題。根據(jù)短文“Until now, even the most advanced (先進的) robot was almost certain to break down when it was damaged.” 描述，可知是因為當(dāng)機器人改變時，電腦就不工作了。故選D。

（2）B 細節(jié)理解題。根據(jù)短文“For the first time, scientists have made a robot that can take a beating(挨打) and keep on going.”描述，可知新技術(shù)將使得機器人在受到損壞后也能繼續(xù)工作。故選B。

（3）C細節(jié)理解題。根據(jù)短文“It may someday help scientists create better artificial (假的) arms and legs ”描述，可知這個人稱代詞指代的是前文提到的假肢，故選C。

（4）C 細節(jié)理解題。根據(jù)短文“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。
