Question

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.

1.Why is the new kind of robots called mobile robots? Because they can _______________.

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.

【解析】

试题分析：这篇短文的作者想要告诉我们，帮助人们找到好的工作，找到一个好的生活方式，这只是教育的一个目的。它其实还有很多其他更重要的作用，教育可以帮助人们提高自己各方面的能力。

1. mobile robots will move around slowly on wheels.可知这种机器人可以再轮子上移动，所以是移动机器人。故选D。

2. about the building will have to be stored in the robot’s small, built-in computer.可知因为有内置的电脑，机器人可以知道方向，故选B。

3. robots will patrol(巡逻) factories, warehoues(仓库)，and museums at night.可知这篇文章讲的是机器人如何巡逻大楼可知主要讲述的是出现了一种新的安保产品。故选A。
