Whenwasitinvented?

Thepassivevoice被动语态在被动语态的句子中,谓语部分的结构是be+过去分词。被动语态的句子的时态变化反映在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

现在完成时have/has+been

过去完成时had+been1.世界上许多国家都讲英文。
