2. 本课语法——省略句①

英语中的省略用法①

为了避免重复或为了使句子更简练，在一些句子中常常省去某一个或某几个成分，这种语法现象在英语中叫省略。一般有以下集中情况：1）词的省略（动词不定式、介词、含有so/not）；2）从句中的省略（宾语从句、状语从句、定语从句）；3）虚拟语气中的省略。本单元我们主要研究前两种省略。

1. 动词不定式的省略

（1）不定式符号to省略:

1）感官动词或使役动词(如 feel, see, hear, notice, let, make, have 等)后接不 定式作宾语补足语时省略 to；

2）在 do noting but, can’t help but, why not, would rather...than..., prefer to do...rather than...等句型中省略 to。

（2）不定式的省略

1） 使用不定式符号 to 来代替整个不定式，常在 be afraid, expect, forget, hope, intend, like, love, mean, prefer, refuse, seem, try, want, wish 等后面；

2）在某些形容词 glad, happy, pleased, delighted 等后面使用不定式符号 to 来 代替整个不定式；

3）如果不定式中含有 be, have, have been，通常保留 be, have 和 have been。

例如：-- Are you a sailor?

      --No, but I used to be.

2. 介词的省略

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.

3. 使用so，not等的省略

英语中，当句中有think，believe，hope，expect，suppose，guess，afraid等词时可以使用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。

例如：--Do you think our team will win the final? —I think so.

--It is said that tomorrow is a fine day. —I am afraid not.

1. Looking through my newspaper, I’m shocked by photos showing that a hurricane in Asia has destroyed a town.

[句式分析] 本句中含有两个非谓语动词。Looking trough..是非谓语动词作状语，由于与逻辑主语I是主动关系，因此用现在分词。第二处showing that...是非谓语动词作定语，修饰photos，因其与逻辑主语photos也是主动关系，因此也用现在分词。

2. Experts say this bad weather has occurred due to climate change.

[句式分析] 本句需掌握occur的相关用法。①occur作“发生”讲时_____________，由此可知，作非谓语动词时也无被动形式，一般用occurring。②occur发生过去式、现在分词变化时注意_________________。③句型：________________________译为“某人突然想起某事”。

[尝试翻译] _______________________________________________________________。
