Thepassivevoice被動(dòng)語態(tài)在被動(dòng)語態(tài)的句子中,謂語部分的結(jié)構(gòu)是be+過去分詞。被動(dòng)語態(tài)的句子的時(shí)態(tài)變化反映在be動(dòng)詞上。也就是說,把一個(gè)句子做成被動(dòng)語態(tài)的句子,只需要寫出be動(dòng)詞的所需時(shí)態(tài),再加上所給動(dòng)詞的過去分詞就行了。當(dāng)然,這只是指謂語部分而言。我們知道,be動(dòng)詞作為一個(gè)獨(dú)立的謂語動(dòng)詞有自己現(xiàn)在分詞(being)和過去分詞(been)。那么,下面我們來看看be在各種時(shí)態(tài)中的變化形式：一般現(xiàn)在時(shí)am/is/are

一般過去時(shí)was/were

一般將來時(shí)shall/will+be

過去將來時(shí)would/should+be

現(xiàn)在進(jìn)行時(shí)am/is/are+being

過去進(jìn)行時(shí)was/were+being

現(xiàn)在完成時(shí)have/has+been

過去完成時(shí)had+been1.世界上許多國家都講英文。
