2020年中考英语知识点之被动语态应注意问题

　　被动语态应注意问题

　　1. 不及物动词无被动语态。

　　What will happen in 100 years./The dinosaurs disappeared about65 million years ago.

　　2. 有些动词用主动形式表示被动意义。

　　This pen writes well. /This new book sells well.

　　3. 感官动词或使役动词使用省略to的动词不定式，主动语态中不带to，但变为被动语态时，须加上to.

　　①makesomebody do something→somebody+ be +made to do something

　　②seesomebody do something→somebody +be +seen to do something

　　③Theboss made the little boy do heavy work.→The little boy was made to doheavy work by the boss.

　　4. 如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。

　　①Hegave me a book.→A book was given to me by him.

　　②Heshowed me a ticket.→A ticket was shown to me by him.

　　5. 一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。

　　We can't laugh at him. →He can't be laughed at by us.
