Grammar Fcus
一般过去时的被动语态由“was/ were +及物动词的过去分词”构成。The mbile phne has greatly influenced peple’s life since it was invented.These bks were written fr children.
一般过去时的被动语态的构成
一般过去时的被动语态的基本用法
一般过去时的被动语态的句式
（1）含双宾语的主动结构变被动结构时，不要忽略间接宾语前的介词。We gave sme flwers t Miss Ga n Teachers’ Day.→ Sme flwers were given t Miss Ga n Teachers’ Day.（2）含有动词短语的主动结构变被动结构时，不要漏掉短语中的介词或副词。We handed in ur hmewrk last Friday. → Our hmewrk was handed in last Friday (by us).
使用被动语态时的注意事项
（3）在含有使役动词make或感官动词（see, watch, ntice, hear 等）的主动语态的句子中，这些词后常跟省略t的动词不定式，但是改为被动语态时则要把省去的t还原。I saw him crss the rad and enter the shp.→ He was seen t crss the rad and enter the shp (by me).
（4）含双宾语的主动结构变为被动结构时，既可将间接宾语转化为主语，也可将直接宾语转化为主语。若将间接宾语转化为主语，则保留直接宾语；若将直接宾语转化为主语，则保留间接宾语，且在被保留的间接宾语前加上介词t或fr。My mther gave me a pencil.→ I was given a pencil by my mther.→ A pencil was given t me by my mther.
（5）其他：There be 结构没有被动语态。Happen, rise, appear, cme ut, take place等不及物动词没有被动语态。主动句中宾语为反身代词的没有被动语态。Lk, sund, smell等系动词或sell，write，wash等表示主语内在“品质”或“性能”的不及物动词可以用主动形式表被动含义。 例：这些书卖得很好。These bks sell well.
