thenewmachinelastweek.Thenewmachine_____________byTomlastweek.wasmadeWhatdidyoufindout?一般过去时的被动语态的句式结构肯定句主语+was/were+及物动词的过去分词（+by…）否定句主语+was/were+not+及物动词的过去分词（+by…)疑问句Was/Were+主语+及物动词的过去分词（+by…)?特殊疑问词+was/were+主语+及物动词的过去分词（+by...)?一般过去时被动语态的结构为“主语+was/were+及物动词的过去分词(+by+动作的执行者).”。如：Treeswereplantedlastyear.去年种了树。一般过去时的被动语态用法示例表示过去某一具体时间发生的动作，且句子的主语是谓语动词动作的承受者Thehousewasbuiltin1990.这所房子建于1990年。讲述发生在过去的动作，且不知道动作的执行者Hewashonoredwiththename“FatherofHybridRice”.他被授予“杂交水稻之父”的称号。一般过去时被动语态考点一：基本用法含有短语的主动语态变被动语态考点二Myfatherfixedupthehouse.Thehousewasfixedupbymyfather.Thehousewasfixedbymyfather.动词短语在变被动语态的时候，不能去掉构成短语动词的介词或副词；要当作一个整体含有双宾语的主动语态变被动语态考点三Tomgavemeabookyesterday.IwasgivenabookbyTom.AbookwasgiventomebyTom.当指“人”的间接宾语变为主语，指“物”的直接宾语保留不变；如果把指“物”的直接宾语变为主语，则在间接语前加to或for直接宾语做主语间接宾语做主语口诀：如遇双宾语，一般变间宾，若把直宾变，to/for间宾连。考点四Isawaheavymanenterthehouse.主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to的动词不定式，变为被动语态时应加上不定式标志to。感官动词和使役动词的被动语态口诀：感使动词真叫怪，to来to去记心怀，主动语态to离去，被动语态to回来。Aheavymanwasseento
