Ellipsis省略
1.基本概念
省略是一种避免重复、保持句子简洁的语法现象。凡是缺少一个或一个以上的必要语言成分, 在一定语境中能够独立存在, 意义明确, 并且能发挥交际功能的句子就是省略句。
一般说来, 只要不破坏语法结构或者引起歧义, 能省略的就应省略。省略不仅使句子结构显得紧凑, 而且也是分句和分句之间的承接纽带。
二、省略的用法
1. 并列句中的省略
一般说来, 在后一并列句中凡是与上文相同的成分通常都可省略。
I came at eight but Henry (came) at nine.
我八点来的, 但亨利是在九点来的。
2. 复合句中的省略
(1)定语从句
如果关系代词在定语从句中作宾语, 这个关系代词可以省略。
He’s the man (who/that)you can safely depend on.
他是你能放心信赖的人。
(2)状语从句
当状语从句的主语和主句的主语一致, 且状语从句中含有be动词时, 省略状语从句中的主语和be动词。
When (the novel is) published, the novel will become one of the best sellers of the year.
那本小说出版的时候就会成为当年的畅销书之一。
(2024·北京高考)And when (he was)asked about his new title, he shared the secret: moderation (适度).
当被问及他的新头衔时，他分享了秘诀:适度
(3)宾语从句
引导宾语从句的that一般情况下, 可以省略。that后面的宾语从句较长或其他一些特殊情况下, that不能省略。
I hope (that) you’ll be fine soon.
我希望你尽快康复。
(4)主句省略
有时整个主句都可省略, 只剩下一个从句。这种省略现象通常出现在简短答语中。
—You all like the story
——你们都喜欢这个故事
—Yes, except that the conclusion is too hasty.
——是的, 只是结尾太仓促。
3. 虚拟语气中的省略
(1)虚拟条件句常省略if, 而将were, had, should提前构成部分倒装。
Had you come here yesterday, you would have met her.
如果你昨天来这儿的话, 你就会见到她了。
(2)在一坚持(insist), 二命令(order, command), 三建议(suggest, propose, advise), 四要求(demand, require, request, ask)等后的宾语从句中, 含这些词的派生词的其他主语从句、同位语从句、表语从句, 以及It is strange/natural/necessary/important that. . . 从句中常省略should。
We insisted that they(should) go with us.
我们坚决要求他们和我们一起走。
4. 动词不定式的省略
(1)有些动词(词组), 如want, wish, expect, hope, would like, try, forget等后面的不定式作宾语时, 为了避免重复, 可以省略动词只保留到to, 但如果在省略的不定式结构中含有系动词be和助动词have, 这些动词就要保留。
The boy wanted to ride his bicycle in the street, but his mother told him not to.
这个男孩想在街上骑自行车, 可他妈妈不同意。
(2)两个或两个以上的不定式并列时, 第一个带to, 后面可以省去to; 但如果两个不定式表示对比关系时, 则to不可省略。
His wish is to earn a lot of money and (to) buy his mother a big house. 他的愿望是赚很多钱给妈妈买所大房子。
(3)感官动词(词组)see, look at, hear, listen to, notice, watch等和使役动词make, let, have等的后面作宾语补足语的不定式要省略to; 但此类动词的被动语态中的to不可省略。
I saw him enter the room just now.
刚才我看见他进了房间。
(4)在某些句式中, 如介词but前有动词do的任何形式, 后面的不定式要省略to。
I can do nothing but wait.
我能做的只有等待。
5. 介词的省略
(1)在英语中一些与动词、名词、形容词搭配的介词常被省略, 而只保留后面的动名词。如spend time/money(in)doing sth. ; have difficulty/trouble(in)doing sth. ;
prevent/stop sb. (from)doing sth. 。
I have some trouble (in) learning English.
我学英语有困难。
(2)表示时间的介词at, on和in在next, last, this, each, these, yesterday, every, tomorrow等词之前, 一般可省略。

每学期我们举行一次期末考试。
6. 替代性省略
英语中, 可以使用so, not或其他手段来省略上文或问句中的一部分或整个句子。
—Can I put my bike here
我可以把自行车放在这儿吗
—You’d better not. 你最好不要。
