动词的时态和语态
Tense & Voice
一、被动语态(passive voice)
1.结构:
be+及物动词过去分词
The game is played by us.
I am attracted by English.
2.使用注意:
a.“感官动词或使役动词+宾语+省略to的动词不定式(宾补)”→
be+感官动词或使役动词的过去分词+带to的动词不定式
A girl saw my wallet drop.
→My wallet was seen to drop by a girl .
使役动词:使役动词表示一种引起发生的动作。换句话说,当我为自己做了一件事时,我就让它发生,或者我实际上什么都不做,而是请别人替我做。这就是使役动词的意义。
五看:look,see,watch,notice,observe
三使:have,make,let
两听:hear,listen to
一感觉:feel
半帮助:help
b. 接双宾语的动词改为被动语态
直接宾语(物)作主语 → 动词后要用介词(固定搭配)

My father bought me a new bike.

A book was given to me by him.
A new bike was bought for me by my father.
