动词语态精讲
Ⅰ. 动词语态的概念:
英语的语态有主动语态和被动语态。主动语态中主语是动作的______。
被动语态(passive voice)是动词的一种形式。被动语态中主语是动作的________ 。
一般来说,只有需要动作对象的及物动词才有被动语态。
汉语往往用"被"、"受"、"给"等被动词来表示被动意义 。
被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式,过去分词部分不变。在被动语态的句子中,动作的执行者一般由介词 by 引起。
例:They always help you. 他们总是帮助你。(主动)
You are always helped by them 你总是被他们帮助。(被动)
【keys】执行者;承受者;

带宾语补足语的句子改为被动语态
将带复合宾语的句子改为被动语态时,一般把主动结构中的宾语改成主语,宾语补足语保留在谓语后面。
例:
We always keep the classroom clean. 变为:The classroom is always kept clean.
带双宾语的句子改为被动语态的两个句型
有些动词,如:give,sell, send 等要求接一个直接宾语(指动作的对象,承受着或后果)和一个间接宾语(指动作是向某人或者为某人做的)。其主动与太本身就有两个句型,因此改为被动也有两个句型:
如:
We awarded him a medal.
We awarded a medal to him.
句型1:讲间接宾语改成主语,而直接宾语保留下来。
句型2:把直接宾语改成置于,把间接宾语改为由to引导的短语。
如:
He was awarded a medal.
A medal was awarded to him.
带宾语从句的句子改成被动语态的两个句型
句型1:宾语从句的主语+be+主句谓语的过去分词+宾语从句谓语动词的不定式恰当形式
句型2:It+be +主句谓语的过去分词+that+原宾语从句
例:
主动:People say she knows five languages.
被动:(1)She is said to know five languages.
(2)It is said that she knows five languages.
说明:
过去分词believed,confirmed,considered,estimated,feared,hoped,known,mentioned,reported,said,thought常可用于这种表达方式。

It is estimated that... It is reported that...

英语中有些动词既可以当及物动词,又可当不及物动词使用,且将作及物动词使用时句子中的宾语改为主语时,仍可用主动与太表示被动(做不及物动词使用)。这类动词有:
begin, bend, break, burst, change, close, cook, continue, crack, crash, decrease, drive, drop, finish, fly, grow, improve, increase, melt, open, rot, run, sail, sell out, shrink, shut slow, split, spread, start, stick, stop, stretch, tear, widen等。
