三、复合句中的省略
1.状语从句的省略
当状语从句的主语跟主句的主语相同或从句的主语为it且从句谓语中含有be动词时,则从句中的主语和be动词常被省略。

注意:若省略句中的谓语动词和主语之间构成主动关系,则使用现在分词;若构成被动关系,则使用过去分词;若谓语动词表示的动作尚未发生,则使用不定式。

如果他不愿意回答这个问题,你不能强迫他。
2.在某些使役动词,如:make,let,have等和感官动词,如:see,watch,notice,observe,hear等后面作宾补的不定式须省略to,但若这些动词用于被动语态,则to不省略。
We often hear her sing an English song in the classroom.
She is often heard to sing an English song in the classroom.(被动语态)
我们经常听见她在教室唱英文歌。
3.并列的不定式可以省略后面的不定式符号to。但若两个不定式之间表示对比关系时,则不能省略to。

五、使用so,not等时的省略
在英语中,可以用so,not或其他方式来省略上文或问句中的一部分或整个句子。
—Can you finish your work today
—I think so.
—I don’t think so./I think not.
——你今天能完成工作吗?

—I guess not.
——男孩子们工作做得一点儿也不好,是吗?
——我猜是没做好。

(3)spend some time (in) doing sth
(4)stop/prevent sb (from) doing sth
