Your mistakes should be corrected right now.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.→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. →　　There are twenty more trees to be planted.二、怎样把主动语态改成被动语态?把主动语态改为被动语态非常简单,可以遵循以下几个步骤：1.先找出谓语动词；2.再找出谓语动词后的宾语；3.把宾语用作被动语态中的主语；4.注意人称、时态和数的变化.例：1.Bruce writes a letter every week. →A letter is written by Bruce every week.2.Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.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 something→somebody+ be +made to do something　　see somebody do something→somebody +be +seen to do something　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.→A book was given to me by him.He showed 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 him. →He can’t be laugh by us.　He listens to the radio every day. →The radio is listened to by him every day.　The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.还有一些是特殊的,要自己去积累 7. 1.I was invited to a birthday party2.The boy was told by us not to go out.3.We were encouraged by the teacher to study hard.4.English was spoken by the people all over the world.5.Homework shoulld be done on time .6.Supper should be cooked at 6 o'clock7.More time is needed to read more book.8.The windows and the doors should be cleaned fair.9.The clothes can be washed at Sunday.10.Many apples are eaten everyday.希望给满意答案.谢谢英语中及物动词有两种语态,即主动语态和被动语态.主动语态表示主语是动作的执行者被动语态表示主语是动作的承受者.被动语态由“助动词be+及物动词的过去分词”构成.助动词be有人称、时态和数的变化.一、被动语态的用法：1.一般现在时的被动语态构成：is / am / are + 及物动词的过去分词　　Our classroom is cleaned everyday.2.一般过去时的被动语态构成：was / were + 及物动词的过去分词A new shop was built last year.3.现在完成时的被动语态构成：has / have + been + 及物动词的过去分词This book has been translated into many languages.Many man-made satellites have been sent up into space by many countries.4.一般将来时的被动语态构成：will+ be + 及物动词的过去分词A new hospital will be built in our city.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.
