□观察领悟【例句观察】①And what a city—a city that was able t rebuild itself after the earthquake that ccurred in 1906.②This district used t be a pr area f twn, but is nw a centre fr art, music, and fd.
【我的领悟】1．句①中 ________ (位置)省略了 ________ (内容)，省略部分在句中作 ________ (成分)；2．句②中 ________ (位置)省略了 ________ (内容)，省略部分在句中作 ________ (成分)。Keys：1.定语从句；a city；主语2．并列句；this district；主语
□省略在英语中，为了使语言简练或避免重复，常常省略句中的一个或某几个成分，这种语法现象称为省略。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，主要是在祈使句中的yu和疑问句中的主语。(Yu) Shut up! 住嘴！(Yu) Want a hand? 需要帮忙吗？(I) Beg yur pardn. 请再说一遍。(It) Desn’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。—D yu knw Miss Ga?—I dn’t knw (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。(Yu cme) This way, please.请这边走。(省略了主语和谓语)(Have yu) Gt any ink?你有墨水吗？(省略了主语和谓语的一部分)
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．省略共同的主语或宾语。Tm picked up a bk n the flr and (Tm) handed it t his teacher.汤姆在地板上捡起了一本书并把它交给了老师。
2．若主语不同，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 ftball and Mary (must have been)ding her hmewrk.杰克肯定一直在踢足球，玛丽肯定一直在做作业。3．若主语与谓语动词相同，则省略后面的主谓成分。His advice made me happy, but (his advice made)Jim angry.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。He has a knwledge f first aid but his friend desn’t (have a knwledge f first aid)．他具备急救知识，但他的朋友不具备。
三、复合句中的省略1．状语从句的省略(1)在when, while, if, as if, thugh, althugh, as, until, nce, whether, unless, whenever等连接的状语从句中，当从句的主语跟主句的主语相同且从句的谓语中含有系动词be或从句的主语为it时，则从句中主语和be动词常被省略。
Wd gives ff much smke while (it is)burning.木头燃烧时产生很多烟。Whenever (it is) pssible, they wuld stp him and ask him the three questins.只要有可能，他们就让他停下并问他这三个问题。Will yu be free this Sunday? If (it is)s, let’s g camping.这个周日你有空吗？如果有，我们去野营吧。
※【拓展提升】省略句中的谓语动词和主语之间构成主动关系，则使用现在分词；若构成被动关系，则使用过去分词；若谓语动词表示的动作尚未发生，则使用不定式。When (it is) heated, ice can be turned int water.加热的时候冰可以变成水。
(2)在than, as等引导的比较状语从句中常省略某些成分。They dn’t use mre water than (it is)necessary.他们使用的水没有超出需要量。He runs as fast as Bb (runs)．他和鲍勃跑得一样快。
※【拓展提升】并非所有的状语从句都可以省略主语和be动词，由after, befre, because等词引导的状语从句一般要改写成介词短语等，用动名词代替be动词。Because he was ill, he didn’t attend the meeting.→Because f being ill, he didn’t attend the meeting.(正)→Being ill, he didn’t attend the meeting.(正)→Because ill, he didn’t attend the meeting.(误)由于生病了，他没有出席会议。
2．定语从句的省略(1)在限制性定语从句中，作宾语用的关系代词whm, which, that可省略(但whm, which紧跟在介词后时不能省略)。The exact year (which/that)Angela and her family spent tgether in China was 2008.安哥拉和她的家人一起在中国度过的确切年份是2008年。(2)修饰way的关系词that/in which可以省略。The way (that/in which)he speaks t us is really annying.他跟我们讲话的方式真是让人讨厌。
3．宾语从句的省略(1)及物动词后接宾语从句时，连接词that一般可以省略；但如果及物动词接两个或两个以上that引导的宾语从句，那么只有第一个that可以省略。I truly believe (that)beauty cmes frm within.我确信美丽来自内心。He said (that)the text was very imprtant and that we shuld learn it by heart.他说这篇课文很重要，我们应该牢记在心。
(2)when, where, hw和why引导的宾语从句有时仅保留引导词。I knw that a mvie star will cme t ur city but I dn’t knw when (he will cme t ur city)．我知道一个电影明星将要来我们市，但我不知道他什么时候来。
四、其他的省略情况1．动词不定式的省略(1)当不定式在形容词afraid, anxius, eager, glad, happy, ready, willing等后作状语时，t后的内容常省略。Yu can’t frce him t answer the questin if he’s nt ready t (answer the questin)．如果他不愿意回答这个问题，你不能强迫他。
(2)某些使役动词如make, let, have等以及感官动词如see, watch, ntice, bserve, hear等后面作宾补的不定式必须省略t，但若这些动词用于被动语态时，则t不省略。We ften hear her sing an English sng in the classrm.She is ften heard t sing an English sng in the classrm.(被动语态)我们经常听见她在教室唱英文歌。
(3)并列的不定式可以省略后面的不定式符号t。但若两个不定式之间表示对比关系时，不能省略t。He likes t swim mre than (t)skate.比起溜冰他更喜欢游泳。He believes it imprtant t study rather than t make friends.(比较)他认为最重要的是学习而不是交朋友。
(4)当不定式在某些动词后作宾语时，常可省略。常见的动词有agree, affrd, expect, frget, hpe, knw, manage, pretend, remember, refuse, want, wish, wuld like等。I wuld d it fr yu, but I dn’t knw hw t (d it fr yu)．我愿意为你做这件事，但是我不知怎么做。
(5)介词but, except (除了)前有实义动词d的某种形式时，后面的不定式不带t。All he culd d was nthing but wait and see.他所能做的只有等着瞧。
(6)当不定式在be ging t, be able t, have t, ught t, used t等后作复合谓语时，不定式可省略。They didn’t visit their parents as much as they ught t (visit their parents)．他们应该多看望父母，但他们没有。
※【拓展提升】①省略的不定式内容若含有做助动词用的have或be的任何形式时，t后要保留原形的have或be；②类似这样用法的还有动词短语ught t, be ging t, be abut t, be suppsed t, have t, used t及形容词glad, happy, pleased, delighted等。
He didn’t cme, but he ught t have cme.他没来，但他应该来。—Are yu a farmer?—N, but I used t be (a farmer)．——你是个农民吗？——不是，但我过去是。
2．使用s, nt等时的省略在英语中，可以用s, nt或其他方式来省略上文或问句中的一部分或整个句子。—Can yu finish yur wrk tday?—I think s.—I dn’t think s./I think nt.——你今天能完成工作吗？——我认为能。——我认为不能。
值得注意的是，hpe, guess, be afraid的否定形式只能用nt的形式，不能用的形式。—The bys are nt ding a gd jb at all, are they?—I guess nt.——男孩子们工作做得一点儿也不好，是吗？——我猜是没做好。
3．介词的省略(1)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。常见的结构有：①have difficulty/truble (in) ding sth.②be busy (in) ding sth.③spend sme time (in) ding sth.④stp/prevent sb.(frm) ding sth.The heavy rain prevented him (frm) arriving there n time.大雨使得他没能按时到达那里。
(2)表示时间的介词at, n和in在next, last, this, these, yesterday, tmrrw, ne, any, every, each, sme等词之前时，一般省略。We g t schl (n) every day except Sundays.除星期天外，我们每天都上学。
