被动语态
在英语中,语态是动词的一种形式,表示主语和谓语的关系。英语动词有两种语态,即主动语态和被动语态。主动语态(active voice)表示主语是动作的执行者;被动语态(passive voice)表示主语是动作的承受者。如:
More and more people use computers now.(主动语态)
Computers are more and more widely used now.(被动语态)
英语表达被动的方式也不复杂,用“助动词be+动词的过去分词”表示。其中助动词be有人称、数量和时态的变化,而这正是英语被动语态的难点。
被动语态由“be+及物动词的过去分词”构成。一定是及物动词的过去分词,因为不及物动词不能带宾语,也就不可能有被动语态。英语主动语态有16个时态;被动语态常用的有8个。
被动语态的疑问句是将第一个助动词移到主语之前、句末用问号;否定式是在第一个助动词后加not或never等其他否定词、句末用句号。如:
“During the interview, were you asked questions in English?” “面试的时候,用英语问你问题了吗?”
“No, I wasn’t asked questions in English.” “没有,没有用英语问我问题。”
被动语态的用法
1、不知道或没有必要指出动作的执行者。换个说法,有一件事情不知道是谁干的或者不想说出是谁干的,这时就用被动语态。例如:
These fighters are imported from Russia. 这些战斗机是从俄国进口的。
I felt a littlie nervous when I was being interviewed. 我接受面试的时候,有点紧张。
That place has been turned into a swimming pool. 那个地方已被变成游泳池。
2、说话或发表意见时,为了显得客观公正,也常用被动语态
He’s said/believed/reported to be in the U. S. A. 据说/据信/据报道他在美国。
还有下列常用句型(that后面跟句子):
It is reported that……. 据报道
It is said that……. 据说
It is hoped that……. 希望
It is announced that……. 据宣布
It is believed that……. 人们相信
it is (well) known that……. 众所周知
It has been decided that……. 已经决定
It is suggested that……. 有人建议
It is supposed that……. 人们认为
It must be remembered that……. 务必记住
It is taken for granted that……. 被视为当然
