Whenwasitinvented?

Thepassivevoice被動語態在被動語態的句子中,謂語部分的結構是be+過去分詞。被動語態的句子的時態變化反映在be動詞上。也就是說,把一個句子做成被動語態的句子,只需要寫出be動詞的所需時態,再加上所給動詞的過去分詞就行了。當然,這只是指謂語部分而言。我們知道,be動詞作為一個獨立的謂語動詞有自己現在分詞(being)和過去分詞(been)。那么,下面我們來看看be在各種時態中的變化形式：一般現在時am/is/are

一般過去時was/were

一般將來時shall/will+be

過去將來時would/should+be

現在進行時am/is/are+being

過去進行時was/were+being

現在完成時have/has+been

過去完成時had+been1.世界上許多國家都講英文。
