17、态 ） 我 教 英 语；Our English is taught by him.（被动语态）我们的英语是由他教的；He speaks English.（ 主 动 语 态 ） 他 说 英 文 ；English is spoken in many countries all over the world.（被动语态）世界很多国家都讲英语；在被动语态的句子中,谓语部分的结构是 be + p.p.（过去分词）；被动语态的句子有时态的变化,这个变化反映在 be 动词上；也就是说,把一个句子做成被动语态的句子,只需要写出BE 动词的所需时态,再加上所给动词的过去分词就行了；当然,这只是指谓语部分而言；我

18、们知道,be 动词作为一个独立的谓语动词有自己现在分词（being ）和过去分词（been）；那么,下面我们来看看 be 在各种时态中的变 化 形 式：一 般 现 在 时 am / is / are 一 般 过 去 时 was / were 一 般 将 来 时 shall / will + be 过 去 将 来 时 would / should + be 现 在 进 行 时 am / is / are + being 过 去 进 行 时 was / were + being 8 / 9 名师归纳总结 - - - - - - -第 8 页,共 9 页精选学习资料 - - - - - - - -
