12.动词的语态
语态有两种：主动语态和主动语态。主语是举措的发出者时为主动语态；主语是举措的接受者时为主动语态。
留意： 1）感官动词主动语态的宾语补足语是不带to
的不定式，变为主动语态时，该不定式前要加"to"。例如：
The teacher made me go out of the
classroom.西席逼我走出课堂。
--" I was made to go out of the classroom（by the
teacher）.
We saw him play football on the
playground.我们瞥见他在草场踢球。
--" He was seen to play football on the playground.
2）模样形状动词+ be +过往分词，组成主动语态。例如：
Coal can be used
to produce electricity for agriculture and industry.煤可以发作工农业需要的电。
