(完整版)主动语态变被动语态专项练习A4讲解

主动语态变为被动语态专项练习（一）、当我们不知道谁是动作的执行者；（二）、或者只需强调动作的承受者时，要用被动语态。

主动语态变被动语态步骤：1、主语和宾语交换位置（即将原来的主语变为宾语、将原来的宾语变为主语）；2、谓语动词变为“be+V过去分词”；3、主动语态中的主语变为介词by的宾语。

一般现在时的被动语态：am/are/is + V过去分词1.People play football all over the world.2.Mr. Green teaches us this term.3.We often play basketball after class.4.They use knives for cutting things.5.Mike often helps his mother to do housework.6.We use cameras for taking photos.7.They don’t make cars in this factory.8.Does she wash the clothes?一般过去时的被动语态：was/were + V过去分词1.People built the Great Wall long ago.2.Two years ago we used the machines to make shoes for children.3.They watched a match on TV.4.He washed the car yesterday.5.The teacher asked the student to bring some photos.6.She sent a postcard to me yesterday.7.The boys didn’t do their homework.8.Did you clean the room last night?一般将来时的被动语态：is/am/are going to + be + V过去分词或will +be+ V过去分词1.We will write a diary next class.2.Tom is going to hold a birthday party.3.We will have a test tomorrow.4.Tom will teach me with my English.5.She will borrow a book from the library.6.I’m going to buy a car next year.7.They are going to finish the work soon.8.We won’t see a movie this Sunday.9.Are you going to buy a computer?含有情态动词的被动语态：情态动词(can/must/should/have to)+be+ V过去分词1.We have to finish our homework on time.2.You must hand in your homework on time.3.We should plant more trees.4.He could play the violin when he was 7.5.We should speak to the old man politely.6.Parents should allow children to choose their own clothes.7.We can’t see the sun at night.带有双宾语（宾语既有人又有物）的被动语态:(1)将间接宾语(人)变为主语，直接宾语(物)不变。
