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(毁坏). 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.”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 |
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 |
The underline word “them” in Paragraph 5 refers to .
| A．sensors | B．robots | C．arms and legs | D．scientists |
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. |
Tina was not like many of her classmates. She didn’t listen to popular music or watch many movies, and she wasn’t interested in nice clothes.

Dear Tom
How are you? I'm at a new school this term. And I'm writing to you about my school now. My new school is big and nice. There are one thousand and four hundred students and one hundred and forty teachers at my school. I like the teachers. They are very kind to me. My classmates are very friendly, too. They teach me Chinese and I teach them English.
There are trees, flowers and green grass at my school. They are very beautiful. Behind my school there is a small river. The water in it is quite clean. We can swim in it.
We have no classes on Saturdays or Sundays. Sometimes I go to play football or basketball with my classmates. Sometimes I stay at home and watch TV. Sometimes I go to shops with my father and mother. We all like China.
Please write to me soon!
Yours
