Section B (Reading 2)
Unit 7 Will people have robots
2.Today there are（有…） already robots working （正在工作）in factories. Some can help to build cars, and they do simple jobs over and over again. （一遍又一遍做简单的工作）Fewer people will do such jobs（这样的工作） in the future because they are boring, but robots will never get bored.（变得厌烦）
Review.
When we watch movies about the future, we
sometimes see robots. They are usually like
human servants.（人类的仆人）They help with
the housework and do jobs like working in dirty
or dangerous places.（像在脏或危险的地方工作）
3.Scientists are now trying to make robots look like humans and do the same things as（和…做相同的事情）we do. Some robots in Japan can walk and dance. They are fun to watch. However, some scientists believe that although we can make robots move like people（让机器人像人类一样移动）, it will be difficult to make them really think like a human（让它们像人类一样思考）. For example, scientist James White thinks that robots will never be able to wake up （将不能醒来）and know where they are. But many scientists disagree with （不同意）Mr. White. They think that robots will even be able to talk like humans in 25 to 50 years.
