初中英语知识点归纳：主动语态与被动语态

　　4. 一般将来时的被动语态构成：will+ be + 及物动词的过去分词　　　　Many more trees will be planted next year.

　　5. 含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词　　Young trees must be watered often.

　　6. 现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词　　Uncle Wang is mending my bike now.rarr; 　　My bike is being repaired by Tom now.

　　7. 不定式的被动语态：to + be + 及物动词的过去分词　　There are two books to be read. rarr; 　　There are twenty more trees to be planted.

　　三、使用被动语态应注意的几个问题：

　　1. 不及物动词无被动语态。　What will happen in 100 years. 　　The dinosaurs disappeared about 65 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。　　例：make somebody do somethingrarr;somebody+ be +made to do something 　　see somebody do somethingrarr;somebody +be +seen to do something 　　The boss made the little boy do heavy work.rarr;The little boy was made to do heavy 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。　　He gave me a book.rarr;A book was given to me by him. 　　He showed me a ticket.rarr;A ticket was shown to me by him.
