• 【高考链接】If Joe' s wife won' t go to the party,
_______.
A. he will either
B. neither will he
• C. he neither will D. either he will
• 解析：答案为B。如果Joe的妻子不去舞会的话，Joe也 不会去。neither引导的连续否定的句子也是一种省略句 而且主谓用倒装，这里nither he will 相当于he will not go to party , neither 。
the way he said it.

• 【高考链接】—Do you have anything to say for yourselves? —Yes，there's one point_____ we must insist on A．why B．where C．how D．/

高考英语一轮复习语法梳理特殊句式（8页Word文档）【考情分析】专门句式1．关于感叹句、祈使句、反意疑问句和否定句的考查要紧从以下几个方面进行：(1)感叹句的考查要点是what与how引导的感叹句作为宾语从句显现在试题中，其难点有两方面：一是复数名词或不可数名词前面用what依旧h ow；二是感叹句的语序。
(2)祈使句的要紧考点是：依照句式特点判定是祈使分句依旧状语成分；祈使句＋and/or＋结果分句。
(3)反意疑问句要紧考查主从复合句和并列句后面的反意疑问句。
(4)否定句的考查要紧是关于部分否定句的辨认。
2．对省略句的考查要紧从以下几个方面进行：(1)省略主语、主语和谓语、主语和谓语的一部分；(2)不定式符号to的省略；(3)状语从句中主语和谓语动词部分的省略；(4)不定式中动词的省略；(5)not，so，neither，nor的“替代性”省略。
3．对倒装句的考查要紧从以下几个方面入手：(1)含有否定意味的词置于句首时，部分倒装；(2)only＋状语位于句首时，部分倒装；(3)so/such...that句型中，so/such位于句首时，so/such后的主句倒装，t hat从句不倒装。
4．对主谓一致的考查重点是：(1)主语＋as well as/together with＋名词/代词；(2)not only...but(also)．...，neither...nor...，either...or...连接两个主语；(3)means，works等词汇作主语。
5．强调句型的考查重点是：（1）考查强调句式的差不多结构（2）考查含有“not…until…”句型的强调句式（3）考查强调句式的疑问句（4）考查强调句式的正确判定交际用语情形交际是高考必考内容，要紧包括适应应答类和语言结构类两种交际用语。
前者要求考生把握一些常见的诸如打、问路、购物等交际话题的固定套语，以及表示感谢、道歉、要求等的应答用语。
2012届高考一轮复习英语(北师大版)课件：语法专项《倒装句》
⑤neither…nor 句型中两个句子都需要部分倒装。如： (6)。 规则2：so/as/neither/nor 位于句首，连接两种相同的情 况时，所连接的并列分句需用部分倒装。 规则3：“only ＋ 副词/介词短语/状语从句” 放在句首 时，句子须用部分倒装，如：(7)。 【特别提醒】 only修饰主语时，不倒装，如：(8)。
规则4：在虚拟语气条件句中，从句谓语有助动词were, had, should时，可将if 省略，而把 were, had, should 移到句首，如：(9)。 【特别提醒】 ①若从句是否定句，则必须将not放在主语后。 ②had必须是助动词。 规则5：在 “so…that” 和 “such…that”结构中，将“so ＋_adj.”和“such＋n._”提到句首时，句子须用部分倒 装，如：(10)。
【注意】 句子的一部分成分(通常是表语或状语)提前，但主谓 语序不变。 1. as连接让步状语从句所引起的倒装详见考点10让步状 语从句。 2. 否定词no matter no matter连接的让步状语从句的句式 “No matter how / wh-＋ … ＋主语＋ 谓语”，如： (11)。 3. how和what引起的感叹句 (1) How ＋形容词/副词＋主语＋谓语，如：(12)。 (2) What ＋形容词＋名词＋主语＋谓语，如：(13)。

高考英语语法精讲第14讲殊句式强调句型,省略,反意疑问句及其他专题复习
强调强调句的基本句型是“It is/was＋被强调的部分＋that/who＋其他部分”。
被强调的部分可以是主语、宾语和状语等。
强调句型的使用特点主要有以下几个方面：(1)被强调的是状语或状语从句时，要用that引导从句，而不能用which，而且通常不能省略。
It was in the park that I met him.我是在公园里遇到他的。
It was in 1964 that the first telephone satellite was set up by the Group of 17 Countries.17国集团发射第一颗电话卫星是在1964年。
(2)被强调的是人时，引导词可用who，也可用that。
Was it you that/who let out the secret to her?是你把这个秘密泄露给她的吗？注意：当被强调的是主语时，代词要用主格形式。
It was I who put forward the theory first.是我最先提出这个理论的。
(3)被强调的不管是单数还是复数名词，主句的be动词都用单数is或was。
It was Madame Curie and her husband who discovered radium.是居里夫人和她的丈夫发现了镭。
It is the PLA men who/that are safeguarding our country day and night.是解放军战士日夜保卫着我们的祖国。
(4)对not...until时间状语从句进行强调时，其句型是：It is/was not until...that从句，即not和until在强调句中总是紧挨着的。
注意习惯上不用not till，而且从句不能用when引导。
It was not until the last operation was finished that Bethune left the battle hospital.直到做完最后一个手术白求恩才离开战地医院。

专题十四强调句和省略句按照考纲要求，考生应能够恰当地使用词语和强调句式对表达的内容进行强调，近几年的高考试题主要考查考生对谓语动词的强调的理解和强调句型的灵活使用，考查复合句中的强调句式；按照考试大纲的要求，考生还应掌握英语省略的一些基本原则，在行文中正确地使用省略。
强调句一、强调句句型1．陈述句的强调句型：It is / was ＋被强调部分(通常是主语、宾语或状语)＋that / who(当强调主语且主语指人)＋其他部分。
It was on the party that he met one of his old friends.2．一般疑问句的强调句型：同上，只是把is / was提到it前面。
Was it on the party that he met one of his old friends?3．特殊疑问句的强调句型：被强调部分(通常是疑问代词或疑问副词)＋is / was ＋it ＋that / who ＋其他部分？When and where was it that you were born?I met the film star—Jackie Chan at Beijing Airport yesterday.强调主语：It was I (that / who) met the film star—Jackie Chan at Beijing Airport yesterday.强调宾语：It was the film star—Jackie Chan that / who I met at Beijing Airport yesterday.强调地点状语：It was at Beijing Airport that I met the film star—Jackie Chan yesterday.强调时间状语：It was yesterday that I met the film star—Jackie Chan at Beijing Airport.注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that和who，即使在强调时间状语和地点状语时也如此，that和who不可省略；强调句中的时态通常用两种：一般现在时和一般过去时。
原句谓语动词是一般过去时、过去完成时和过去进行时，用It was...，其余的时态用It is...二、not...until...句型的强调句1．句型为：It is / was not until ＋被强调部分＋that ＋其他部分It was not until the last operation was finished that Bethune left the battle hospital.注意：此句型只用until，不用till。
但如果不是强调句型，till和until可通用。
因为句型中It is / was not...已经是否定句了，that后面的从句要用肯定句，切勿再用否定句。
三、谓语动词的强调1．It is / was...that...结构不能强调谓语，如果需要强调谓语时，用助动词do / does或did。
Do sit down.He did write to you last week.Do be careful when you cross the street.注意：此种强调只用do / does和did ，没有别的形式；过去时用did ，后面的谓语动词用原形。
省略句为了使讲话和行文简洁，句中某些成分有时可省略。
省略可分以下几种情况：一、简单句中的省略1．省略主语：祈使句中主语通常省略。
其他省略主语的用法多限于少数现成的说法。
(I) Thank you for your help.(I) See you tomorrow.(It) Doesn't matter.2．省略主谓语或主谓语的一部分。
(There is) No smoking.(Is there) Anything wrong?Why (do you) not say hello to him?3．不定式的省略(1)使役动词let, make, have及感官动词see, watch, hear, notice, observe, feel, look at, listen to 等后面作宾语补足的不定式要省去to, 但在被动句时应加上to。
I saw the boy fall from the tree.The boy was seen to fall from the tree.2)mean, try, want, afford, decide, refuse, wish, like, need, would like, would love...等后面接不定式作宾语时，省略作宾语的不定式。
只保留不定式符号to, 但如果该宾语是动词be 或完成时态的不定式时，则需在to后加上be 或have。
—Are you going there?—Yes, I'd like to (go there)．—Are you an engineer?—No, but I want to be (an engineer)．3)tell, warn, order, advise, ask, expect等动词后接不定式作宾补时常省略不定式的宾语补足语。

但如表示对比(照)等，则不省略to。

He was thought (to be ) the cleverest boy in the group.6)特殊结构中的省略would sooner, had better, do nothing but, have nothing to do but, there's nothing to do but, can't help but, rather than 等后的不定式的符号to常省略。
He would sooner die than surrender.I'd rather look after the baby than wash dishes.7)主语部分有一个表“做”的do 的各种形式时，表语不定式常省略“to”。
What I really want to do is (to) go to the cinema.4．省略表语—Are you thirsty?—Yes, I am (thirsty)．5．同时省略几个成分Let's meet at the same place as (we met) yesterday.—Have you finished your work?—(I have) Not (finished my work) yet.二、并列句中的省略两个并列分句中，后一个分句常省略与前一分句中相同的部分。

(I'm) Sorry to hear that you are ill.(It is a) Pity that he missed such a good chance.2．从句的省略(1)宾语从句以which, when, where, how和why引导的宾语从句在其谓语与主句谓语相同时，可省略全部谓语，甚至主语也省略，仅保留一个wh－词。
She will go to Beijing, but I don't know when (she will go to Beijing.)(2)状语从句在时间、地点、让步、方式、条件状语从句中，如果主语与主句主语一致，或者主语是it，那么动词be及其主语通常可省略。
常见的有以下几种：时间状语从句：Be careful when (you are) crossing the street.条件状语从句：He won't go to the party unless (he is) invited.比较状语从句：Country music today remains much the same as (it was) before.让步状语从句：Whether (it is) right or wrong, his opinion should be paid attention to.注意：though和as 引导让步状语从句时，通常从句要倒装。

Why was it (that) you were ten minutes late?用so或not时切不可用it或that代替。
—Is he coming back tonight?—I think so.—Is he feeling better today?—I'm afraid not.这种用法常见的有：How so? Why so? Is that so? I hope so. He said so.及I suppose not. I believednot. I hope not等。
