主动语态与被动语态的转换9大注意事项

1.主动语态变为被动语态，主语变为介系词by的宾语，宾语变为主语，人称代名词的格也要变化。

Peter, I heard he was hit by you. (被)

Peter, I heard you hit him. (主)

彼得，我听说你打了他。

I hit him.(主)

He was hit by me. (被)

我打了他。

2.主动语态变为被动语态，句子的时态保持不变。

I will give him a pen.(主)

He will be given a pen by me.(被)

我将给他一支笔。

3.一些与格动词的被动语态有两种形式;另一些与格动词如：write, make, bring等的被动语态则只能以直接宾语作主语。

Tom was given a toy by me. (被)

I will give Tom a toy. (主)

她给我写了一封信。

write当述语动词，在此只能用直接宾语letter当被动语态的主语。

4.在感官动词或使役动词后作补语的原形动词，在被动语态中用不定词。

You were heard to talk with Peter. (被)

I heard you talk with Peter. (主)

6.否定句的被动语态中，not放在第一个助动词后。

I should not be blamed by you. (被)

You should not blame me. (主)

你不应该责怪我。

You should not write this letter.(主)

This letter should not be written by you.(被)

7.疑问句的被动语态中，用BE的对应形式代替DO。

8.祈使句的被动语态形式为：let+宾语+be+过去分词。
