    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.

During the day we work and play，and at night we sleep. Our body rests when we sleep. In the morning we are ready to work and play again. Our body grows most when we are asleep. Children who are tired usually need sleep. We can get better at our lessons after having plenty of rest. Boys and girls who are eight or nine years old need ten hours of sleep every night. Our body needs plenty of air when we are asleep. If we do not get enough fresh air, we will feel tired when we wake up. While in bed we must not cover(覆盖) our head，our lungs need to get enough fresh air. If we open our windows at night，we can have plenty of fresh air. Cool air is better than warm air.

For many years, scientists have said that the earth is getting warmer. Now they have found something new—hot cities! In the southern US, they have found that cities become very hot in summer. For example, the city of Atlanta in Georgia has roof(屋顶) temperature of up to 50^oC while it is 27℃ in the streets! At night, the outside of buildings stays so hot that the heat of the city causes storms over the city!

China also has the same kind of problems. Every year more farmland is used for factories or offices. More housing is needed, too. As people become richer, they buy more cars. New roads are needed and new car parks are built in the city centers. This all makes cities hotter.

It isn't easy to change the situation. City planners say that we should plant more trees in the middle of cities. Every new street should have trees on both sides, they say. Trees make the temperature lower, so we should have more trees in our parks and squares. We should also paint our roofs white. If we do this, they do not become so hot. Every roof in a hot and sunny country should have solar(太阳的) roof panels. The electricity from these can be used to run the air conditioners (空调)in the buildings.

People continue to cut down forests around the cities. This makes the problem worse. Cities are growing faster and faster. By the year 2025, four fifths(五分之四) of the population will be living in cities. If we go on like this, there will not be enough farmland to feed everyone in the world.

Hi, my name is Wu Ping. I'm a girl student in a middle school in Shenzhen, China. Let me tell you something about my school life.

I go to school five days a week. At school, I have Chinese, maths, English, history, music and science on Monday. Science is my favourite subject. I think it's fun and useful. But my friend Huang Wei thinks it's boring. On Tuesday, we have a football game.

The boys in our class are in it, and we girls only watch them play. On Wednesday, we have a geography class. Mr Wang is our geography teacher. We all like him and his classes because he is funny. On Thursday, we have an English party in the evening. It is interesting. But I don't like Friday because we have maths on that day and maths is really difficult for me.

I really like my school life.
