What’s a big problem in Shenzhen today, do you think? Besides pollution, traffic is, of course.
There are too many people, too many cars but too little space so the roads are always busy. You can almost see traffic jams everywhere. It is even worse when everyone is going to school or to work. What’s more, cars need fuel(燃料) to move, so they let out a lot of dirty smoke and pollute the air.
However, the government is trying many ways to solve the problem. We can see more roads and footbridges over the main streets. And the workers are making some roads wider. It is said every car will have a computer. The computer can study the latest traffic news. Then it will look over its own map for the best way to drive and they won’t get into traffic jams.

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(jìn)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(dòng)機(jī)) 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(shù)) 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．a(chǎn)rms 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.
