高中英语语法动词的语态讲解
动词的语态时态是高考考察重点之一,也是难点之一,通过本文本站将教会你如何使用动词的语态时态等
来看看吧
语态有两种:主动语态和被动语态。主语是动作的发出者时为主动语态;主语是动作的接受者时为被动语态。
注意:1)感官动词主动语态的宾语补足语是不带to 的不定式,变为被动语态时,该不定式前要加\"to\"。例如:
The teacher made me go out of the classroom. 老师逼我走出教室。
--> I was made to go out of the classroom (by the teacher).
We saw him play football on the playground. 我们看见他在草场踢球。
--> 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。例如:
Coal can be used to produce electricity for agriculture and industry. 煤可以产生工农业需要的电。
12.1 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。例如:
They let the strange go.他们放陌生人走了。
---> The strange was let go.
2)当let 后宾补较长时,let 通常不用被动语态,而用allow或permit 代替。例如:
The nurse let me go to see my classmate in the hospital. 那护士让我去探望住院的同学。
----> I was allowed / permitted to see my classmate in the hospital.
12.2 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。例如:
My sister will be taken care of by Grandma. 我妹妹由奶奶照顾。
Such a thing has never been heard of before. 这样的事闻所未闻。
