They are usually like human servants . They help with the housework and do jobs like working in dirty or dangerous places.2Today there are already robots working in factories. Some can help to build cars, and they do simple jobs over and over again . Fewer people will do such jobs in the future because they are boring, but robots will never get bored.3Scientists are now trying to make robots look like humans and do the same things as 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，it will be difficult to make them really think like a human. For example，scientist James White thinks that robots will never be able to wake up and know where they are. But many scientists disagree with Mr.White.They think that robots will even be able to talk like humans in 25 to 50 years.4Some scientists believe that there will be more robots in the future. However， they agree it may take hundreds of years.These new robots will have many differentshapes.Some will look like humans, and others might look like animals.In India, for example，scientists made robots that look like snakes.If buildings fall down with people inside, these snake robots can help look for people under the buildings.This was not possible 20 years ago, but computers and rockets also seemed impossible 100 years ago.We never know what will happen in the future！ human / hjumn / n.人人 【辨析】 human，person與people講解來自講解來自點撥點撥知識點知識點1 1human也寫作human being，意為“人”；它的復(fù)數(shù)形式為humans。person指個體的“人”，有單復(fù)數(shù)形式?！耙粋€人”應(yīng)該說a person，不能說a people?？枷蚩枷颉疽族e點【易錯點】 講解來自講解來自點撥點撥people意為“人，人們”時，著重指集體，為集合名詞；也有“民族”之意，此時它的復(fù)數(shù)形式為peoples，a people意為“一個民族”。eg：Robots will look like humans. 機器人將會看上去像人類。 There were only two persons in the office yesterday afternoon. 昨天下午辦公室里只有兩個人。講解來自講解來自點撥點撥 People are dancing in the street. 人們正在街上跳舞。 There are 56 peoples in our country. 我們的國家有56個民族。典例典例An old _ wants to see you.ApersonBpeopleChumansDmen A【點撥【點撥】因前有】因前有an old限定，所以用單數(shù)。限定，所以用單數(shù)。 dangerous /dendrs/ adj.有危險的；有危險的； 不安不安 全的全的知識點知識點 dangerous 反義詞是safe。常用句型為：Its dangerous to do sth.做是危險的。eg：Dont play with fire.
