Once there lived a very old farmer in a village. His name was jack. He had a horse. It was almost as old as he was.

　　One day he set off（出发） with his young son to sell the horse. They walked because the father didn't want the horse to be 　　too tired.

　　　　They met two neighbours on their way. The neighbours said,"Hello, why are you walking? You have a horse. It's a long way to 　　the market." Jack knew that was true, so he rode on the horse while his son was walking.

　　　　Then they met two women." What are you doing there? Can't you see how tired your boy is?" So Jack got down, and his son rode 　　instead .

　　　　Next, three old men stopped them. One of them said, "Why are you walking, Jack? It's too hot for an old man like you to walk today."

　　So Jack got on behind his son and they rode on.

　　Some time later, a girl passed them. "Why aren't you walking?"she asked. "It's not far from the market. Give your poor horse a 　　rest."

　　　　So Jack and his son got down once again.

　　It's the fact that you can't make all people pleased all the time.

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 patrol(巡逻) factories, warehoues(仓库)，and museums at night.

The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) 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 barred from the area it patrols.

One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam 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 will be hard to steal anyway. It will weigh 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.
