大多数“主-动-宾”结构的主动句都可以转换为被动句。 (1)将原来的宾语变为主语，并将原来的主动态动词词组变为被动态动词词组。 This factory produces machine tools. →Machine tools are produced in this factory. The found a wallet in the car. →A wallet was found in the car. They are repairingthe bridge. →The bridge is being repaired. They have repaired the bridge. →The bridge has been repaired. They often make fun of her. →She is often made fun of. He took great care of his books. →His books were taken great care of. →Great care was taken of his books. (2)如果原句带有情态动词或半助动词，在变为被动句时，助动词不变，随后的主动词变为被动态。 They should do this right now. → This should bedone right now. They may be interviewing the applicants at the moment. →The applicants maybe being interviewed at the moment. They must have finished their work. →Their work must have been finished He is likely tolet you down. →You are likely tobe let down. (3)当主动句变被动句，如果要强调施动者，可将原句主语置于by- 词组中表达出来。 A boy found this wallet in the street. →This wallet was found in the street by a boy. (4)当主动句是一个“主-动-宾-宾”结构时，可以有两种形式。 Father gave me a toy yesterday. →I was given a toy yesterday. →A toy was given to me yesterday. (5)当主动句是一个“主-动-宾-补”结构时，可将原来的宾语变为被动句的主语，原来的宾语补语变为被动句里的主语补语。 They named the boy Tom. →The boy was named Tom. We painted the wall pink. →The wall was painted pink. (责任编辑：admin) |
