(正) The flowers smell sweet. (误) The flowers are smelt sweet. 2.主语 + 不及物动词 (S+V) 此结构不可变被动语态. (正) An accident happened last night. (误) An accident was happened last night. 3.主语 + 及物动词 + 宾语 (S + V+ O) (1)将主动语态的宾语变为被动语态的主语 Children often sing this song This song is often sung by children. (2)将含有介词或副词的动词短语变为被动结构时,不可将介词或副词去掉. We should listen to the teachers carefully. The teachers should be listened to carefully. 4.主语 + 及物动词 + 间接宾语 + 直接宾语 (S + V+ IO+ DO) (1).将表人的间接宾语变为主语,直接宾语不变. He showed us a picture . We were shown a picture. (2).将指物的直接宾语变为主语,要在间接宾语前加介词 to 或 for. 常用加 to 的动词 give, show, pass, read 等 常用加 for 的动词 buy, get, make, sing, draw 等 A picture was shown to us. A dictionary was bought for me by my parents. 5. 主语+及物动词 + 宾语 + 宾语补足语 (S+ V+ O + C) 如动词为 make, see, hear, watch 等,后接宾语补足语为不带to不定式时,变被动语态时要加上to . I saw him fall off the tree. He was seen to fall off the tree. 6. be + 过去分词 并非都是被动语态,系动词 be, feel, seem,look,等词后面的过去分词已转化为形容词, 作表语用,表示某种状态. Im interested in mathematics. 我对数学感兴趣. *7. 某些动词用主动语态来表示被动含义.The womans clothes sell well. 女装卖的快.This book sells best.这本书很畅销. 1 被动语态专项练习 1 一,选择题 ( )1. a new library in our school last year?
