题目内容

Many companies use guards and expensive alarm systems to protect their property（财产）. Soon a new kind of protection will be used—robots. Engineers have been working on the first mobile robots for businesses. The robots will guard factories, warehouses（仓库）and museums at night.

The mobile robots will move around slowly on wheels. They will be able to detect（察觉，发现） people through walls and pick up sounds, such as breaking glass. They can be fixed with loud sirens to frighten thieves, or radios to signal police or guards.

To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.

A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be prevented from entering the area it moves.

One kind of mobile robot will be able to “sense” whether a chair or a box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alarm if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot is hard to be stolen anyway. It weighs about 200 pounds.

U.S. companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.

A. guard factories, warehouses and museums

B. send loud, painful sirens when it is stolen

C. sense moving objects and signal police

D. move around and do the programmed work

2.How will a robot get directions for moving around a building?

A. From a human guard. B. From a built-in computer.

C. From another robot. D. From radio signals.

3.What can be the best title of this passage?

A. New Guards. B. Science and Technology.

C. Alarm Systems. D. Engineers and Robots.

People all over the world eat rice. Millions of people in Asia, Africa and South America eat it every day of their lives. Some people eat almost nothing but rice.

Rice is a kind of grass. There are more than 7, 000 kinds of rice. Farmers grow rice in many countries, even in the southern part of the United States and in eastern Australia.

No one really knows where rice came from. Some scientists think that it started to grow in two places. They think that one kind of rice grew in southern Asia thousands of years ago. Someone in China wrote about it almost 5, 000 years ago. Another kind probably grew in west Africa. Other scientists think that rice came from India, and Indian travelers took it to other parts of the world.

There are two main ways to grow rice. Most rice grows in wet soil. People in many countries do all of the work of growing rice by hand. This is the same way farmers worked hundreds of years ago. In some countries, people now use machines on their rice farms.

People use every part of the rice plant. They make animal food and rice oil from it. They also make baskets, brooms and roofs for their houses. They burn dry rice plants in fires for cooking.
