第三版块：语法——省略
为了避免重复，或为了使句子更加简练，在一些句子中常常省去一个或某几个成分，这种语法现象在英语中叫省略。
在英语句子中，常见的省略情况有以下几种：
一、简单句中的省略
1．省略主语：一般情况下，主语是不能省略的，但在祈使句和其他不容易引起歧义的情况下，特别是在口语中，主语常常省略。主要有：祈使句中的you和疑问句中的主语。
(You) Shut up！住嘴！
(You) Want a hand？需要帮忙吗？
(I) Beg your pardon.请再说一道。
(It) Doesn't matter.没关系。
2．省略宾语：当上、下或前后两个句子的宾语一致时，下句或后句常省略宾语。
—Do you know Miss Gao
—I don't know (her)．
——你认识高女士吗？
——不认识。
3．省略主语和谓语(或谓语的一部分)：在某些具体的场合下，主语和谓语都很明确，此时为了简化或显得亲切等，可将主语和谓语(或谓语的一部分)同时省略，只剩下表语、宾语、状语或其他成分。
(You come) This way, please.
请这边走。(省略了主语和谓语)
(Have you) Got any ink
你有墨水吗？(省略了主语和谓语的一部分)

It looks like rain.
Let's do the dishes. I'll wash and you dry them.
Have you got any idea about the plan
二、并列句中的省略
在由and或but连接的并列句中，常省略一些重复的词或词组。
1．省略主语或宾语：当后面主语或宾语与前面一部分相同时，可以省略后一部分中共同的主语或宾语。
Tom picked up a book on the floor and (Tom) handed it to his teacher.汤姆在地板上捡起了一本书并把它交给了老师。
2．省略系动词、助动词或情态动词：当主语不同，而谓语部分的系动词，助动词或情态动词相同，则省略后面的系动词、助动词或情态动词。
Jack must have been playing football and Mary (must have been) doing her homework.
杰克肯定一直在踢足球，玛丽肯定一直在做家庭作业。
3．省略主谓成分：当主语与谓语动词相同，则省略后面的主谓成分。

他的建议使我高兴，却使吉姆生气。
4．若主语不同，但主要动词及后续部分相同，则省略主要动词及后续部分。
