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. (296)

小题1:细节理解题。根据文章第二段The mobile robots will move around slowly on wheels.我们可以知道,这种机器人可以四处移动,做好保卫工作。故选D。
小题2:细节理解题。根据文章第二段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,在这种机器人的内部有一个内置的电脑,存储着建筑物的地图,所以这种机器人可以四处移动,而不会撞到墙上。故选B。
小题3:主旨大意题。这篇短文主要就是给我们介绍了一种可以替代人来做安保工作的机器人,这里new guards 指的就是这种新型的机器人。故选A。

The air hostess was kept so busy that she forgot to give him the water. As a result, the passenger was held up to take his medicine. Thirty minutes later, when the passenger’s ring for service sounded, the air hostess hurried over to him with a cup of water, but he refused it.
In the following hours on the plane, each time the air hostess passed the passenger, she would ask him with a smile whether he needed help or not. But the passenger never replied to her.
When the passenger was going to get off the plane, he asked the air hostess to hand him the passenger’s booklet. She knew that he would write down sharp words about her job, but with a smile she handed it to him.

My family and I want to take a trip this summer somewhere in eastern China. I hope you can provide me with some about the kinds of vocations that your firm can offer. We would like to travel to an place and we don’t mind how far we have to go. It has to be a place where we can do lots of activities; we especially love hiking and swimming, but any kind of outdoor activity is fine. We also need to stay in an hotel or apartment. It would be nice if we could get a room with a kitchen so we could save money by cooking our own meals. The room needs to be for three people. Also, we’d like to stay at a place with a big pool or somewhere near the ocean. Could you please give me some suggestions for vacation spots?
Thank you very much!

Tony:
My most embarrassing experience happened when I had just left university. I had just started teaching in a Liverpool middle school. One morning my alarm clock didn’t ring. I woke up at half past eight and school began at nine. I quickly washed, dressed, jumped into my car and rushed to school. When I arrived, the students had already gone into class. I didn’t go to the office, but went straight into class. After two or three minutes the students began laughing, and I couldn’t understand why! Suddenly I looked down and understood. I had put on one black shoe and one brown shoe!
Henry:
The most embarrassing experience I’ve ever had happened two years ago. After seeing a film, my wife and I had lunch in our favorite restaurant in town. Then we decided to take a walk along the street. The street was very busy and we started holding hands. Suddenly my wife saw a dress that she liked in a shop window, and stopped. I started looking at some watches in the next window. After a minute or two I reached for my wife’s hand. There was a loud scream, and a woman slapped my face. I hadn’t taken my wife’s hand. I’d taken the hand of a complete stranger(陌生人)!
