省略句（教师） 一、概念：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。省略是为了避免重复、突出新信息并使上下文紧密连接的一种语法手段。 二、考点：状语从句的省略，介词的省略 三、省略句的用法 1.状语从句中的省略用法 （1）如果从句的主语和主句的主语一致，且从句的谓语含有be动词的某种形式（am/is/are/was/were），可同时省略从句的主语和be动词的某种形式。（主语一致从有be，省略从句主be） ①when, while引导的时间状语从句 · Do be careful when (you are) crossing the street. · When/While (I was) on my way to work, I met her. · I’ll not go to the party unless (I am) invited. · Once (you are) caught stealing in a supermarket, you will be punished. · 以if从句为代表的状语从句中的特殊省略用法： 通常省略了it is, that is, there is/are，惯用表达有if any 即使有（任何）……，即使有……；if ever （即使有……也）极少，难得；if necessary 如果有必要的话；if not 假如不是这样的话，不然的话，否则；if possible 如果可能的话；if so假如这样的话。 · Correct errors, if any (=if there are any errors). · He seldom, if ever, goes to the movies by himself. 2. 介词的省略 一些与动词、名词或形容词搭配的介词常常可以省略，而保留介词后的动名词，如： have difficult/ trouble (in) doing sth 有困难做某事 the busy (in) doing sth 忙于做某事 spend time (in) doing sth 花时间做某事 stop/prevent sb from doing sth 阻止做某事 3. 不定式符号to的省略 （1）感官实义动词see, hear, feel, watch等和使役动词have, make, let等后接不定式作宾语时，不定式省略to。 （2）前有do（实义动词）后无to & 无do（实义动词）有to的用法，用连词连接前后： I have nothing to do but watch TV all day long. 短语：have nothing to do but do... Tom have no choice but to give it up. 短语：have no choice but to do... We did nothing but stay at home watching TV yesterday. （3）can’t help but等结构常接省略to的不定式。 Hearing the news, she couldn’t help but cry. 【课前知识点检测】 a pity 一种遗憾 devote to doing 致力于... solutions to ... ...的解决办法 be willing to do 乐意，愿意 come up with 想出 divide ... into 将...分为 call for 要求，需要 It was absolutely worth our effort. 我们的努力是完全值得的。 【巩固练习】 1.
