Module 8 Unit 2 Grammar 省略 教学案在英语中，有时为了言简意赅，突出关键词语；有时为了避免重复；有时因为语法的客观要求，句子中的一个或几个成分不需要表达出来，这种现象称为省略。英语中的省略的原则既不破坏语法结构， 同时又不能产生歧义(要保持句子意义的准确无误)。英语的省略大致有以下几种情况：1 不使用替代词的省略（1） 省略主语 I have done more than (what ) is required. (You) Open the door for me, please.（2） 省略主谓语或主谓语的一部分 Why (do) not (you) say goodbye to your lovely cousin ? (Are you ) Ready ?Try to answer these questions in your own words.（3） 省略宾语 -Which of them is better ? -Well, it is hard to tell (which of them is better).（4） 省略表语 -Are you hungry ? -Yes, I am (hungry).（5） 省略所有格后面的名词Jack and his sister stayed in his uncles(home) during the summer vacation.The girls handwriting is much better than his brothers (handwriting).（6） 在限定性定语从句中作宾语的关系代词that，which, whom可以省略；在以the same. as和such. as引导的定语从句中，可以省略与主句相同的部分；the way后面的定语从句中，可以省略that，in which；在含被动语态的定语从句中，关系代词作主语时，可以省略关系代词和be,省略之后,变成过去分词短语作定语。如：The book (that) he bought last week is written by Guo Jingming.Here is the wonderful book (which )I have read many times.The man (whom) you had said hello to was my English teacher.（7） 不定式中的省略a 英语中为避免重复，经常省略上下文已提到的动词原形，只保留不定式中的小品词to；这类动词有：expect,forget,hope,intend,mean,prefer,refuse,try,want,wish,would like和love等。如： She asked me to dance with her,but I didnt want to (dance with her). -Do you want to give us a lecture about how to use an English dictionary? -No, I prefer not to (give a lecture about how to use an English dictionary)b 在have to, need, ought to, be going to, used to等后省略动词。如： I really didnt want to go there with him,but I had to (go there with him). c不定式在happy，glad，eager，ready，willing等形容词后面作状语时，可以省略，但要保留不定式符号to。如：-Will you join in our discussion ? -Ill be glad to (join in your discussion). d 如果不定式中带有be, have, have been等，通常保留be, have, have been。如： -Did he pass the driving test ? -No,but he ought to have (passed the driving test). f介词but后的不定式和作表语的不定式，它们前面出现了行为动词do的任何形式；在 and或or并列的第二个不定式中不能带to。 In very cold weather, the hibernating（冬眠） animals had no choice but to lie down to sleep. He could do nothing but wait.2使用替代词的省略（1） 通常情况下，在省略了某个词、短语或句子时，还需要用某个替代词。常用的替代词有：do /does /did, so, not, neither, nor和the same等。用助动词do /does /did来替代上下文出现的动词，以免重复。如：She speaks English more fluently than her elder sister does.（2） 用so可替代单词、短语或句子(用于肯定) not用于否定，宾语从句可以省略，作believe, be afraid, expect, do, fear, hope, suppose, say, think 等的宾语。如：-Will it be fine tomorrow ? -I hope so. (I hope that it will be fine tomorrow.)3. 常见的省略结构（）在虚拟条件句中，当助动词为were, had, should等时，连词if可省略，但were, had和should等需要倒装到主语的前面。如：Had I had time,I would have gone shopping with you.Were I you, I would go there and help him.Should the teacher have time next week,he would come to the party.（）如果状语从句的主语和主句的主语一致，并且从句的谓语部分有be动词，状语从句的结构是“从属连词+主语+be动词+其它结构”, 则可以将状语从句中的“主语+be动词” 一起省略,引导这类主语从句的连词有：由when，while，as, once，whenever引导的时间状语从句；或由if，unless引导的条件状语从句；由though，although，even if ，even though引导的让步状语从句；由as though，as if，as引导的方式状语从句；由because引导的原因状语从句；由wherever引导的地点状语从句，等。如：If invited, I will go to his party. (If invited=If I am invited.)Though young, he knows a lot of things. (Though young=Though he is young) The old woman was knocked down while (she was)crossing the street. The little girl began to cry when (she was) asked by the police. 有些状语从句中，如果从句的主语是it，其后的be动词及其主语可以一起省略。这种结构通常为if it is possible, when it is necessary等。:如：When possible, Mr. Li will ask us some questions in English. (When possible=When it is possible)Please try to finish your homework by yourself if (it is) possible.Well have the old house pulled down when (it is) necessary.（）在作状语的独立主格结构中，分词短语往往可以部分被省略。如：The work (having been)done,the secretary left the office and went home.The weather (being)fine,we decided to go on a picnic on the beach. （4 ） 由and连接的that引导的两个从句，第二个that不能省略。如： The teacher told me (that) I had passed the driving test and that I could have a rest the next day.【考考你】 一、 单项填空1-Do you think it will snow tomorrow ? - _.
