二、阅读理解
Robots seem very new to some people, but in fact they have a long history. The first robot was made by a Greek inventor(发明家). You may often see robots in lots of movies. The robots in the movies are stronger, faster and cleverer than people. In real life, most robots are used in factories. They are used to do many dangerous, difficult or boring jobs. Some people can’t look after themselves and robots are used to help them. For example, some people can’t see. They use dogs to help themselves move around. These dogs are called guide dogs. Scientists are making robots to help them. In the future, robot dogs might take the place of these guide dogs.
Robots are also used in American hospitals. At one hospital, a robot takes meals from the kitchen to the sick people’s rooms. It never loses its way because it has a map of the hospital in its computer system(系统).
In the future, robots will work in space. But robots will never take the place of humans, though they can help us in a lot of different ways.
