Question

 

Many companies use guards and expensive alarm systems to protect their property (財(cái)產(chǎn)). 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 (倉(cāng)庫(kù)) and museums at night.

    The mobile robots will move around slowly on wheels. They will be able to detect (察覺(jué),發(fā)現(xiàn)) 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.  (296)

3.A

試題分析：這篇短文為我們介紹了一種新型的機(jī)器人，這種可移動(dòng)的機(jī)器人可以用來(lái)替代安保人員，來(lái)保衛(wèi)工廠、公司、博物館等地方的安全。有了這種機(jī)器人可以大大的節(jié)約人力，而且也更便宜。但是使用這種機(jī)器人也有不方便的一些地方。

【解析】

1.細(xì)節(jié)理解題。根據(jù)文章第二段The mobile robots will move around slowly on wheels.我們可以知道，這種機(jī)器人可以四處移動(dòng)，做好保衛(wèi)工作。故選D。

2.細(xì)節(jié)理解題。根據(jù)文章第二段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.可知，在這種機(jī)器人的內(nèi)部有一個(gè)內(nèi)置的電腦，存儲(chǔ)著建筑物的地圖，所以這種機(jī)器人可以四處移動(dòng)，而不會(huì)撞到墻上。故選B。

3.主旨大意題。這篇短文主要就是給我們介紹了一種可以替代人來(lái)做安保工作的機(jī)器人，這里new guards 指的就是這種新型的機(jī)器人。故選A。
