阅读理解。 If someone asked you to draw a picture of a robot, how would it look?  Like a person? That's how we often picture robots in our minds. But real robots look many different ways. Some robots have TV cameras for eyes. Some have special parts that help them touch. Many have computer brains. How robots look depends on the job they have to do. Some can even have their parts changed,so they can do different jobs. Some robots look like huge insects. America sent some robots to Mars (火星) in 1976. They moved on the surface and did experiments there. Robots can do boring jobs. They can do dangerous jobs with fast-moving machine. They can do dirty jobs, such as painting things with oil colours. They can do jobs no person could do, such as picking up hot metal. Robots don't get bored. They don't get tired. They don't mind getting dirty. Some people are worried because they think robots will take jobs away from people. But that doesn't have to happen. After all, people are able to control robots. People must remember that robots are good at some things and humans are good at others. Some robots often tell people they don't have to be afraid of robots. These robots help people understand that robots can do boring, dangerous and dirty jobs and people can do better ones. 1. 判断正误 (“T”表示正确，“F”表示错误) (     ) All robots look like real persons. 2.
