高中英语语法总结大全之动词的语态
动词的语态
语态有两种:主动语态和被动语态。
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。
1)若宾语补足语是不带to 的不定式,变为被动语态时,该不定式前要加"to"。此类动词为感官动词。
feel, hear, help, listen to, look at, make, observe, see, notice, watch
The teaade me go out of the classroom.
--> I was made to go out of the classroom (by the teacher).
We saw him play football on the playground.
--> He was seen to play football on the playground.
2)情态动词+ be +过去分词,构成被动语态。
Coal can be used to produce electricity for agriculture and industry.
let 的用法
1)当let后只有一个单音节动词,变被动语态时,可用不带to 的不定式。
They let the strange go.---> The strange was let go.
2)若let 后宾补较长时,let 通常不用被动语态,而用allow或permit 代替。
The nurse let me go to see my ate in the hospital.
----> I was allowed / permitted to see my ate in the hospital.
短语动词的被动语态
短语动词是一个整体,不可丢掉后面的介词或副词。
