为了避免重复，将句子中的一个或几个成分省去，这种语法现象叫省略。省略是避免重复、突出新信息并使上下文紧密连接的一种语法手段。英语中的省略有下列几种情况。
(You) Open the door, please.请开一下门。(祈使句)(You come)This way please.请这边走。—Do you know Mr. Lu ? 你认识路先生吗?— I don’t know (him.) 我不认识他4. What a beautiful city (it is)! (感叹句的省略:省略主语谓语)1．如果主语不同，而谓语动词中的一部分相同，则省略谓语动词中相同的部分。John must have been playing football and Mary (must have been) doing her homework.Their advice made us happy, but(their advice made) Amy sad.他们的建议使我们开心，但是却使艾米担忧。Old McDonald gave up smoking for a while，but (he) soon returned to his old ways.4．在并列复合句中，如果that从句从属于第二个并列句且它的谓语动词和宾语等其他一些成分与第一个并列句相同时，这个that从句通常可以省略这Jack will sing at the party, but I know John won't （sing at the party）. 杰克将在晚会上唱歌，但我知道约 翰不会在晚会上唱歌。些相同的部分。5.如果及物动词后面是由that引导的两个或两个以上的并列的宾语从句 ，那么只有第一个that可以省略He said (that) he loves you and that he wants to marry you.在as if，if，though，when，where，while，no matter what，until等引导的状语从句中，若谓语部分含有be动词，而主语又与主句的主语一致或从句主语是it时，从句的主语和谓语中的be动词可以一起省略。When (she was) very young，she began to learn to play the piano.在她很小的时候，她就开始学弹钢琴。Don't come in until(you are) asked to.不叫你时，请你不要进来。He did as(he had been) told.他按照被告知的那样去做了。Though(they were)tired，they went on working.虽然他们累了，但他们仍继续工作。Tom (whom) you saw yesterday fell ill.(whom可以省) 你昨天见到的汤姆病倒了。 I don t like the way (that/in which)you laugh at her.我不喜欢你嘲笑他的行为。1.
