(It is a pity we live so far from the sea.)有时也可省略整个句子的主语和谓语，只保留次要成分。She was poor but (she was) honest.-Did you know anything about
2、 the accident?-Not until you told me. (= I didnt know anything about it until you told me.)谓语的省略-what do you think made Mary so upset?-Losing her new bicycle (made Mary so upset).状语从句的省略Seen from the plane (when it is seen from the plane), the house looks like tiny toys.If (it is) possible, Ill go t
3、here with you.注意状语从句中的主语同主句主语的一致性。不定式的省略The boy wanted to ride his bicycle in the street, but his mother told him not to. (not to ride his bicycle in the street.)-Alice, why didnt you come yesterday?-I was going to (come yesterday), but I had an unexpected visitor.若不定式后面是完成时，省略时应保留have；不定式后含有动词be的结构
4、时，也要保留be动词。-Did you tell him the news?-I ought to have (told him the news), but I didnt know how to speak.-Are you an engineer?-No, but I want to be.、状语从句中的省略用法一、 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。1、 when，while引导的时间状语从句e.g. Do be careful when (you are) crossi

6、，whether，no matter whether/what/how/who等引导的让步状语从句e.g. He was happy, though/although (he was) poor. Whether (she is) sick or well, she is always cheerful.

7、s eyes and yawned as if/though (he was) waking up after a long sleep. He stood up as if/though (he wanted) to leave.（as if/though + to do表示一个将来的动作）二、 than，as引导的比较状语从句中的省略用法：当不同的主语进行比较时，一般省略从句中的谓语；当从句中的主语与谓语（be动词除外）和主句中的主语与谓语相同时，通常省略从句中的主语和谓语，只保留比较部分。e.g. He is taller than his brother (is). I have as
8、 much as confidence in you as (I have confidence) in him.三、 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。e.g. If (it is) possible/necessary, this old temple will be rebuilt.

9、y.、定语从句中的省略用法关系词的省略 关系代词that，which，whom等在限制性定语从句中充当宾语且不位于介词之后时，可以省略；in which或that在先行词way后作方式状语从句时可省略。e.g. The man (that/who/whom) you visited last night is my grandpa. I dont like the way (in which/that) you treat the girl.、虚拟语气中if及should的省略1、 当条件状语从句中有were，had，should等时省略if，把它们提至句首，形成倒装句。e.g. If I w

11、ake，let等后接不定式作宾语时，不定式省略to。(一感feel,二听hear, listen to, 三让have, let, make,四看see, look at, observe, watch)2、 do nothing but，cant help but等结构常接省略to的不定式。E.g. We didnt do anything but stay at home watching TV yesterday. Hearing the news, she couldnt help but cry.3、 在特定语境中为了避免重复，当不定式再次出现时，在want，wish，hope，tr
12、y，plan，like，love，hate后往往只保留to，而省略后面的动词。但不定式后有be，have时，也保留be和have。E.g.

13、e meeting?
