文章来源:句解霸 | 更新日期:2013-06-23

1) 不定式的省略

* Did you get a ticket? No, I tried to, but there weren't any left. 你买到票了吗? 没有,我去买来着,但卖完了。

2) 并列的不定式
当有两个或两个以上的不定式并列时,通常可只保留第一个不定式的to, 而省列其余不定式的to。
* She decided to remain in the enemy rear and carry on underground work. 她决定留在敌后干地下工作。
* They are taught to read,write and do many other things at school.在学校, 老师教他们读书、写字以及其他很多事情。

注: 对比关系的不定式不能省略to

* Wouldn't it be better for her to continue to do this work than to take up something new? 让她继续做这工作,而不另外做新的工作是不是更好一些?

3) 分裂不定式
不定式的动词可以有副词修饰, 即在to和动词之间可插入副词。这种情况称为分裂不定式。
* He prepared to silently accompany her. 他准备默默地陪伴着她。
* I'm sorry to have always been interrupting you.   很抱歉我总是打扰你。
* It would take ages to really master this subject. 这门学科需要很多年才能真正掌握。
