语法知识一. 被动语态1. “语态”表示主语和谓语动词之间的关系。

英语中有“两态”的说法，即主动语态和被动语态，本单元中反复出现的should be allowed 就是一个含有情态动词（should）的被动语态。

先看几个基本概念主语是动作的发出者为主动语态主语是动作的接受者为被动语态只有及物动词才有被动语态。

2. 被动语态的构成（1）His office is cleaned every day.The office was cleaned yesterday.Compare active and passive：动作的接受者the office成了句子的主语，就应该用被动语态。

从上面的例句我们可以总结：一般现在时的被动语态为：主＋am / is / are （not）＋过去分词一般过去时的被动语态为：主＋was / were ＋过去分词如：Butter is made from milk.This house was built 100 years ago.以前我们学过的was / were born 生于，就是一个被动语态born是个过去分词（bear）－When were you born ? －I was born in 1989.如果要特别强调动作或行为的执行者，句子后面需接by ~ ，译为“被（由）…”如：We were woken up by a loud noise .我们被嘈杂的声音吵醒。

（2）现在进行时被动语态的构成为主语＋is / am / are + being ＋过去分词再如：My car is being repaired now.Some new houses are being built near the park.公园附近在建一些房子。
