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.”
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 house work for humans |
| B．keep working after being damaged |
| C．remember a lot of information |
| D．tell people where it is |
The underlined word “them” in Paragraph5 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. |
The passage is probably from_____________.
| A．a newspaper | B．an advertisement |
| C．a tour guide | D．an application |
阅读下面材料，从每题所给的三个选项（A、B和C）中，选出最佳选项。
In the months of December and January, China experienced some of the worst air pollution in its history. At times, Beijing’s Air Quality Index(AQI)was measured at 406. Any AQI reading over 150 is considered “unhealthy” and any reading over 300 is considered “hazardous.” In Shanghai, we had several days when the AQI neared 300. The PM2.5 readings were also high. PM2.5 refers to particulate (微粒的)matter smaller than 2.5 microns(微米) in diameter. These particles are small enough to get into the lungs and can cause cancer and other lung diseases.
China is now becoming acutely aware that the rush to development has come at a price and may be endangering the health of its citizens. This is something other countries have faced before. The U.K. used to be the most polluted country in the world. It wasn’t until London’s Big Smog of 1952 that people realized that air pollution was a real health hazard. Twelve thousand deaths were directly related to that “pea-souper(浓雾)” and it resulted in Parliament(英国议会)passing the Clean Air Act(《清洁空气法案》)of 1956.
China will no doubt pass similar laws. It’s a choice between wealth and health. As Beijingers and Shanghainese coughed their way through December and January, the choice may have become easier to make.
According to the following AQI, if you are in _________now, it is healthy for you.
A. Shanghai. B. Guangzhou. C. Beijing. Why did Parliament pass the Clean Air Act of 1956?
A. Thousands of people died because of the “pea-souper”.
B. The PM2.5 readings were very low in UK.
C. The Parliament wanted to pass more laws. Which of the following is True according to the passage?
A. The U.K. is the most polluted country in the world now.
B. PM2.5 may cause cancer and other lung diseases.
C. China will not pass similar laws like the Clean Air Act.The underlined word “hazardous” means “______” in Chinese.
A. 危险的 B. 温和的 C. 健康的 According to the passage, why will China pass laws to make air cleaner?
A. It may help the country develop more rapidly.
B. People can’t make the choice between wealth and health.
C. People realize air pollution was a real health hazard.
