掌握特殊句式的几种形式。
【基础知识】
考点一 倒装句
1．全部倒装
(1)表示方向/方位、地点和时间的副词或介词短语，如here, there, now, then, up, down, in, away, off, out, back, on the wall, over there, under the tree, in front of等置于句首，且主语是名词而不是代词时。

约翰打开门，那儿站着一位他从来没见过的女孩。
②Just in front of the bus lies an injured man, all covered with blood.
公共汽车的前面躺着一个受伤的人，浑身是血。
(2)代词such放在句首，且在句中作表语时。
③Such are the facts; no one can deny them.
这些就是事实，没有人可以否认它们。

④Seated in the first row are some advanced workers.
坐在第一排的是一些先进工作者。
⑤Present at the meeting were some scientists from China.

[注意] 上述情况中，若主语是人称代词，则不用倒装。
2．部分倒装
(1)so/neither/nor置于句首时，用部分倒装结构。
a．“so＋be动词/助动词/情态动词＋主语”表示前面所说的肯定情况也适合于另一人或物，意为“……也是如此”。
①—I've got an enormous amount of work to do.
—So have I.
——我有大量的工作要做。
——我也如此。
b．“neither/nor＋be动词/助动词/情态动词＋主语”表示前面所说的否定内容也适用于另一人或物，意为“……也不这样”。
②I don't like it, neither does Tom.
我不喜欢它，汤姆也不喜欢它。
(2)表示否定意义的副词、连词或短语置于句首时。
此类词有not, neither, never, hardly, seldom, nor, scarcely, barely, little, no, nowhere, not only, not until, at no time, by no means, in no way等。

(4)当“only＋状语(副词、介词短语或从句)”置于句首时。
⑥Only in this way can you solve this problem.

要是早复习了功课，你有可能就通过考试了。
⑬Should it not rain tomorrow, we would go for a picnic.
要是明天不下雨，我们就可以去野餐。
考点二 强调句
1．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、宾语或状语等。
It is not how much we do but how much love we put into what we do that benefits our work most.
给我们工作带来最大益处的不是我们做了多少而是我们将多少热爱投入到我们所从事的事业中去。
2．强调句的几种句式
强调句的
特殊句式
构成
例句
一般
疑问句
Is/Was it＋被强调部分＋that/who＋句子其他部分？
Was it Tom who was to blame？
正是汤姆应负责任吗？
特殊
疑问句
特殊疑问词＋is/was it＋that＋句子其他部分？
The patient looks much better.What is it that has made him what he is today？
那个病人看上去好多了。是什么让他变成今天这样的呢？
not until
句式
It is/was not until ... ＋that＋句子其他部分
It was not until midnight that we got home because of traffic jams.
因为交通阻塞，直到半夜我们才到家。
not ...
but ... 句式
It is not ... but ... that ...
It is not quantity but quality that counts.
重要的不是数量而是质量。
3．用助动词强调谓语
如果要强调时态为一般现在时或一般过去时的肯定句中的谓语动词，我们在该动词前加助动词do, does或did。
①Many of the films are from the USA, but we do give awards to films from other countries.
许多电影来自于美国，但我们的确也给其他国家的影片颁奖。
②He did come to see you last Sunday, but you were out.
他上周日的确来看过你，但是你出去了。
[注意] (1)强调句型用于强调主语时，要注意谓语动词(原句)与该主语在人称和数上保持一致。
(2)强调句型的考点主要集中构成强调句型的基本元素that/who上，要明确的一点是，这两个词是不作成分的。
(3)强调句型不用于强调谓语、表语和定语；强调谓语时要用“助动词do/does/did＋动词原形”；但有时，为了表达的需要，用倒装结构对表语进行强调。
(4)注意区分强调句型与结构相似的含有that引导的定语从句的主从复合句(It is ... that ...)；区分的方法也很简单，就是看that是不是在句中作成分，作成分则不是强调句型。
4．强调句型的判断方法
判断一个句子是否是强调句型可采用还原法，即把it is/was和that/who去掉，如果剩下的部分仍然能组成一个完整的句子，该句就是强调句型，否则就不是。
①It was Wei Fang that/who met me in the park yesterday.
昨天在公园遇见我的人是魏芳。
(把It was和that/who去掉可以得到句子：Wei Fang met me in the park yesterday.此句句意和结构均完整，故原句为强调句)
②It is a pity that we missed the wonderful film.
遗憾的是我们错过了那部好电影。
(把It is和that去掉之后，无论是将a pity放在句首还是句末，句子均不合理，很显然原句不是强调句。本句中，it作形式主语，that引导主语从句。)
考点三 省略句
1．在when, while, whenever, till, if, unless, as if, though, than, as等引导的状语从句中，若谓语部分含有be动词，而主语又与主句主语相同或主语是it时，从句的主语和be动词常被省略。
①The experiment shows that proper amounts of exercise, if carried out regularly, can improve our health.
实验表明，如果有规律地进行适量运动，人们能强身健体。
②Work hard when (you are) young, or you'll regret.
少壮不努力，老大徒伤悲。
③While walking along the street, I heard my name called.
走在大街上时，我听见有人叫我的名字。
[注意] 特殊的省略结构：if省略结构，常作为插入语来处理。
if so 如果这样的话
if not 若非如此
if ever 如果曾经有的话
if necessary 如果有必要的话
if possible 如果可能的话
if any 如果有的话
If necessary，ring me. 如有必要，给我打电话。
If possible，let me know beforehand. 如有可能，事先通知我。
④Get up early tomorrow, if not (you don't get up early), you will miss the first bus.
明天早点起床，如果不的话，你将会错过头班公共汽车。
⑤Whenever (it is) possible, he will come to my help.
他会在任何可能的时候来帮助我。
2．I'm afraid, I think, I believe, I hope, I guess等作答句，后面跟so与not分别相当于肯定或否定，宾语从句可省去。
①—Do you think it will rain?
—I hope not/that it will not rain.
——你认为会下雨吗？
——我希望不要下。
②—Do you believe our team will win?
—I guess so.
——你相信我们队会赢吗？
——我猜会赢。
3．不定式省略，即单独使用不定式符号to。
(1)用来代替动词不定式后被省略的动词，常在be afraid/glad/happy, expect, forget, hope, intend, like, love, mean, prefer, refuse, seem, try, want, wish等的后边。
①I asked him to see a film, but he didn't want to.
我请他去看电影，但他不想去。
②—Will you join in the game?
—I'd be glad to.
——你愿意加入游戏吗？
——我很高兴加入。
(2)如果不定式中含有be, have, have been，通常保留be, have和have been。
③—Are you a sailor?
—No, but I used to be.
——你是海员吗？
——不，但我过去是。
(3)省略不定式符号to的情况。
a．当主语部分含有动词do的某种形式时，作表语的不定式可省略to。
④The only thing you have to do is press the button.
你唯一要做的事情就是按按钮。
b．不定式作介词but, except的宾语，前面有实义动词do的某种形式时，不定式常省略to。
⑤Brian had nothing to do but play computer games this afternoon.
今天下午布莱恩除了玩电脑游戏外无事可做。
c．当两个或两个以上的不定式并列时，后面的不定式符号to可省略，但表示对比关系时则不能省略。
⑥I'm really puzzled what to think of and express.
我真的不知道想什么和表达什么。
⑦It is easier to make a plan than to carry it out.
制订计划比执行计划容易。
d．在see, watch, hear, feel, observe, notice, look at, listen to等感官动词及使役动词let, make, have后作宾语补足语的不定式不加to，但当宾语补足语变为主语补足语时，不定式要加上to。
⑧She saw him walk into the house.
她看到他走进了那座房子。
⑨He was seen to walk into the house.
有人看到他走进了那座房子。
⑩He had two boys wash his car.
他让两个男孩给他洗车。
e．you'd better/why not后跟不带to的不定式。

为什么不再试试？

当你想追赶他人时，你最好起得早些。
考点四 反意疑问句及其他
1．反意疑问句
(1)祈使句式的反意疑问句
a．肯定的祈使句，简短问句用will you/won't you。
b．否定的祈使句，简短问句用will you。
c．let's和let us引导的祈使句：let's表“建议，征询”之意时，含听话者在内，故简短问句用shall we；let us表“建议、征询”之意时，不含听话者在内，故简短问句用will you。
①Let's go out for a walk after supper, shall we?
晚饭后我们散散步，好吗？
(2)must表示猜测时的反意疑问句
a．“must be”对现在的情况进行推测，按一般现在时或现在进行时的附加疑问句进行处理。
②He must be honest, isn't he?
他肯定很诚实，不是吗？
b．“must＋完成时”用来推测过去的动作，强调对现在的影响。句中没有表示过去时间的状语时，按现在完成时的附加疑问句来处理；如有明确的表过去的时间状语，按一般过去时处理。
③They must have gone there last night, didn't they?
昨天晚上他们肯定去那里了，不是吗？
④He must have known the truth, hasn't he?

[注意] 主句中含有think/believe/suppose/consider/ ... ＋宾语从句的情况：
(1)若陈述部分为“I/We think/believe/suppose/consider/ ... ＋宾语从句”，简短问句的主语和谓语与宾语从句的主语和谓语分别保持一致，且简短问句用否定形式。
I suppose that she is careful, isn't she?
我认为她很认真，不是吗？
We believe she can do it better, can't she?
我们相信她能做得更好，不是吗？
(2)若陈述部分为“I/We don't think/believe/suppose/consider/ ... ＋宾语从句”，简短问句的主语和谓语与宾语从句的主语和谓语保持一致，且简短问句用肯定形式。
I don't think that you can do it, can you?
我认为这件事你做不了，你能吗？
We don't believe that the news is true, is it?
我们认为消息不实，是吗？
(3)若陈述部分为“主语(非第一人称)＋think/believe/suppose/consider/ ... ＋宾语从句”，简短问句的主语和谓语与主句的主语和谓语保持一致，而且简短问句是用肯定形式还是否定形式由主句决定。
They all think that English is very useful, don't they?
他们都认为英语很重要，是吗？

2．祈使句＋and/or/otherwise＋简单句(多用将来时)

[注意] 注意区分分词作状语结构＋主句与该句型，如不细心很容易弄混，关注有没有连词即可。
3．感叹句
(1)what引导的感叹句
a．What＋a/an＋adj.＋单数可数名词(＋主语＋谓语)!

b．How＋adj.＋a/an＋单数可数名词(＋主语＋谓语)!
④How clever a boy he is!
他是一个多么聪明的男孩啊！
4．There be句型
There be 句型表示“某时间/空间存在/有……”，there本身没有词义，be是谓语动词，be后面的名词/代词是主语。be可以有不同的形式，而且可以和情态动词连用。
(1)There be句型中的be
a．There be句型中的谓语动词be在人称和数上应与其后的主语保持一致。
①There is a flower in the bottle.
瓶中有一朵花。

⑤Once upon a time there lived an old fisherman in a village by the sea.
从前在海边的一个村庄里住着一位老渔夫。
【考点剖析】
考点一 倒装句中助动词、系动词、情态动词的缺失或主谓不一致
(1)【误】Only when he was 30 years old he begin to learn English.
【正】Only when he was 30 years old did he begin to learn English.
[解析] 当only和所修饰的状语位于句首时，引起部分倒装，根据语境可知，主句应用一般过去时，故倒装后应提取助动词did。
(2)【误】Next door to ours lives a foreign couple, who seem to have settled into life in China.
【正】Next door to ours live a foreign couple, who seem to have settled into life in China.
[解析] 此句是完全倒装结构，句子的真正主语是a foreign couple，故谓语动词用复数形式live。
[注意] 造成以上错误是因为对倒装句掌握不牢，建议加强对考点一的学习。
考点二 强调句型与三大从句(名词性从句、定语从句、状语从句)的误用
【误】It's more than half a century that my grandfather joined the Party and became a servant of the people.
【正】It's more than half a century since my grandfather joined the Party and became a servant of the people.
[解析] 此句是“It is＋一段时间＋since ...”句型。
[注意] 造成以上错误主要是对强调句型的判断方法(详参考点二第4点)认识不清而致，强调句型与三大从句的区别：
(1)与名词性从句区别：
强调句型去掉It is/was和that之后，句子结构仍然完整，语义通顺，而名词性从句却不能。
It is there that accidents often happen.(强调句)
正是在那儿经常发生事故。
It is a fact that English is being accepted as an international language.(名词性从句)
英语作为一门国际语言正被广为接受是个事实。
(2)与定语从句区别：
强调句中that没有语义，且不作任何成分，而定语从句中that为关系代词，在从句中充当主语、宾语或表语。
It is novels that Miss William enjoys reading.(强调句)
威廉小姐喜欢读的是小说。
It is a question that needs careful consideration.(定语从句)
这是一个需认真考虑的问题。
(3)与时间状语从句区别：
强调句型去掉It is/was和that后，结构完整，而It is ... when ... 中，it指代时间。
It was at six o'clock that I got up today. (强调句)
今天我是在六点起的床。
It was six o'clock when I got up today. (时间状语从句)
今天我起床时已六点了。
考点三 省略句中to的缺失
【误】She was reading in bed, and her mother told her not.
【正】She was reading in bed, and her mother told her not to.
[解析] 动词不定式在like, love, care, want, hope, wish, expect, prefer, refuse, decide, mean, intend, try, promise等动词后作宾语时，为了避免重复，常常省略不定式后的内容，但要保留不定式符号to。
[注意] 加强对考点三“不定式的省略”部分的学习。
考点四 感叹句中what与how的误用
【误】You simply can't imagine how a wonderful time we have been having!
【正】You simply can't imagine what a wonderful time we have been having!
[解析] 句意：你们简直无法想象我们过得有多么愉快！
[注意] 加强对考点四第3点“感叹句”的学习，要熟知其结构，了解how修饰的中心词为形容词或副词，而what修饰的中心词为名词。
考点五 祈使句、反意疑问句中的常见错误
(1)【误】They don't believe she is an engineer, isn't she?
【正】They don't believe she is an engineer, do they?
[解析] 当主句的主语为二、三人称时，其反意疑问句应与主句一致，与从句无关。
(2)【误】Study hard, or you'll succeed.
【误】Studying hard, and you'll succeed.
【正】Study hard, and you'll succeed.
【正】Studying hard, you'll succeed.
[解析] 本句要么用“祈使句＋and/or/otherwise＋简单句”结构，因逗号前后为并列递进关系，故应用and；要么用非谓语动词作状语的形式，但必须有主句，故将Study改为Studying，并将and去掉。
[注意] 反意疑问句的错误主要集中在对肯定、否定及人称把握不准上；祈使句的错误主要集中在“祈使句＋and/or/otherwise＋简单句”的句型与非谓语动词的混淆上。应加强对考点四第1点和第2点的学习。
【真题演练】
1．(2019·天津高考)The professor warned the students that on no account ________ they use mobile phones in his class.
【答案】should
【解析】考查虚拟语气。warn的宾语从句用should+动词原形。句意：教授警告学生在他的课堂任何情况下都不能使用手机。
2．(2018·全国卷Ⅱ)Diets have changed in China—and so too ________ its top crop.
【答案】has
【解析】考查倒装句。so+助动词、情态动词+主语，表示…也。
3．(2018·天津高考)It was only when the car pulled up in front of our house ________ we saw Lily in the passenger seat.
【答案】that
【解析】考查强调句。句意：只有当那辆车子停在我们房子前面，我们才看见莉莉坐在乘客的座位上。
4．(2017·江苏高考)________ it not for the support of the teachers, the student could not overcome her difficulty.
【答案】Were
【解析】考查虚拟语气。本句省略了if,句意：如果不是因为老师的支持，这个学生是不可能克服困难的。
5．(2016·全国卷Ⅱ)It could be anything—gardening, cooking, music, sports—but whatever it is, ________ (make) sure it's a relief from daily stress rather than another thing to worry about.
【答案】make
【解析】考查祈使句。句意：它可以是任何事情—园艺，做饭，音乐，运动—但是无论是什么，一定要确保它是日常生活压力的一种缓解，而不是另一种担忧。
解题两步骤
第1步 注意分析句式结构，确定为何种特殊句式。
第2步 根据特殊句式的结构特点填入适当的词。
1．(2020·全国卷Ⅰ)Turning to a page in your journal to your list of strengths and achievements.
__________________________________________________________________
【答案】Turning→Turn
【解析】考查祈使句。
2．(2018·北京高考)In any unsafe situation, simply pressing the button and a highlytrained agent will get you the help you need.
__________________________________________________________________
【答案】pressing→press
【解析】考查祈使句。
遇到特殊句式，要注意主谓一致、强调句、倒装句、省略句、感叹句等的构成特点。
[温馨提示] 特殊句式虽种类繁多，但在高考的语法填空和短文改错中出现的频率并不是很高，大部分为对固定句式结构的考查。在复习时，认真研读例句，勤练高考真题和模拟题，熟练掌握基础知识，便可轻松应对。
【过关检测】
1._____________ basic first-aid techniques will help you respond quickly to emergencies.
A. Known B. Having known
C. Knowing D. Being known
【答案】C
【解析】考查动名词作主语。句意：了解基本的急救知识可以帮助您快速应对紧急情况。分析句子成分，谓语是will help，所以前面的是主语，用动名词做主语，故选C项。
2.Though________ to see us, the professor gave us a warm welcome.
A. surprising B. to surprise
C. being surprised D. surprised
【答案】D
【解析】考查状语从句的省略。句意：教授见到我们虽然很惊讶，但还是热情地欢迎了我们。be surprised to do，对做某事很惊讶，在though引导的让步状语从句中，当从句主语与主句主语一致且含有be的某种形式时，可省略从句的主语和be，本句完整形式为：Though he was surprised to see us，相当于省略了he was，故选D。
3.He doesn’t think that the plan is practical, _____?
A. does he B. doesn’t he C. is it D. isn’t it
【答案】C
【解析】考查反意疑问句。句意：他认为这个计划不切实际，是吗？A. does he他是吗；B. doesn’t he 他不是吗；C. is it它是吗；D. isn’t it它不是吗。分析可知，句子句式属于“I(we) don’t think +that从句”，在该句式中，从句为否定意义，反意疑问句部分的系动词/助动词/情态动词和主语要与that从句保持一致且用肯定式，因此在本题中，反意疑问句应是与从句中的系动词“is”保持一致，主语与“the plan”保持一致，用第三人称单数“it”代替，故反意疑问句为：is it。故选C项。
4.China’s image is improving steadily, with more countries ________ its role in international affairs.
A. recognizing B. being recognized
C. to be recognized D. recognized
【答案】A
【解析】考查with复合结构。句意：中国的形象正在稳步提升，更多的国家认识到中国在国际事务中的作用。“更多的国家”和“认识”之间是主动关系，用现在分词，故选A。
5.When ______ different cultures, we often pay attention only to the differences without noticing many similarities.
A. being compared B. comparing
C. Compared D. having been compared
【答案】B
【解析】考查状语从句省略。句意：当比较不同的文化的时候，我们通常总注意到它们之间的区别而没有注意到它们之间的相似之处。当从句省略主语的时候，暗指的主语必须和主句的主语一致，“When ” 后没有主语，所以它暗指的主语必须是后面主句的主语，就是“'we”，也就是说从句里的compare 的主语是we，表示“我们在比较”, compare与句子we构成主动关系，使用动词的现在分词，且与主句主语pay attention to同时发生，用一般式。A项是被动式；C项是过去分词，D项是完成被动式，均表示被动。故B项正确。
6.In any unsafe situation, simply ________ the button and a highly-trained agent will get you the help you need.
A. press B. to press
C. pressing D. pressed
【答案】A
【解析】考查祈使句。句意：在任何不安全的情况下，仅仅摁一下这个按钮，一个训练有素的特工就会使你得到你需要的帮助。and是连词，连接并列结构，and后面是一个句子，那么，前面也应是句子，选项中只有动词原形可以构成祈使句，其余的都是非谓语动词，无法构成句子。故A选项正确。
点睛：祈使句+and/or+陈述句是一种常见结构。当前后两部分间为承接关系时，用and；前后意思为相反关系时，用or。该句式中的陈述句部分常用一般将来时态。
7.I wish I ________ football game on TV last night, but I went to a friend's birthday party.
A. watched B. had watched C. would watch D. were watching
【答案】B
【解析】考查虚拟语气。句意：我希望我昨晚看了电视上的足球比赛，但是我去了一个朋友的生日聚会。分析可知，wish后的宾语从句，应用虚拟语气，由时间状语last night可知该句是对过去发生事情的虚拟，结构为：wish + 主语 + had + 过去分词。故选B项。
8.It was only after experiencing the failure________ he began to train seriously and he won the championship in the 400-metcr freestyle a year later.
A. when B. whether C. that D. which
【答案】C
【解析】考查强调句。句意：在经历了失败后，他开始认真训练，并在一年后赢得了400米自由泳冠军。分析句子可知，该句去掉It was和设空处仍然是完整的句子，由此可知此处考查该强调句，结构为：It is + 被强调部分 + that/who（强调人时可用who）...，该句被强调部分为状语，只能用that。故选C项。
9.I feel it is you as well as your wife that ______ for your son's bad performance at school.
A. are to blame B. is to be blamed
C. are to be blamed D. is to be blamed
【答案】A
【解析】考查强调句中的主谓一致。句意：你儿子在学校成绩不好，我觉得你和你妻子都应该受到责备。as well as连接两个并列主语，谓语动词要和前一主语保持一致，因此be动词用are；动词blame不用被动语态，常用be to blame主动式表被动意义。故选A项。
10.Catherine, ____ the alarm clock for 6 o’clock, or you would oversleep and be late for the train.
A. setting B. sets C. set D. to set
【答案】C
【解析】考查祈使句。句意：凯瑟琳，把闹钟定到6点，否则你会睡过头，火车就赶不上了。分析句子并结合句意可知此处为“祈使句+or+陈述句”结构，用动词原形，故选Ｃ。
11.I wonder when it was_______ you came to realize ________his words meant.
A. that; what B. what; that C. what; what D. that; which
【答案】A
【解析】考查强调句及宾语从句。句意：我想知道究竟是什么时候你意识到他所说的话的真正意思是什么。本句是一个多重复合句。I wonder后是when引导的强调句式的特殊疑问句，可以复原为“It was (when) that you came to realize…”以协助理解，所以空一用强调句的引导词that；及物动词realize后接宾语从句，该从句中动词meant后的宾语缺失，即空二应填入能充当meant宾语的疑问词来引导宾语从句，结构为meant sth.(what)，故what正确。故选A。
12.Only when _______ be possible to sign the papers.
A. does the lawyer come with it B. the lawyer comes will it
C. has the lawyer come it will D. the lawyer comes it will
【答案】B
【解析】考查倒装。句意：只有律师来了才有可能在文件上签字。only + 状语从句位于句首，主句要进行部分倒装，从句不倒装。故选B。
13.This discovery helped researchers conclude that these two drugs, when ___ together, could lead to heart disease.
A taken B. taking
C. to take D. having taken
【答案】A
【解析】考查非谓语动词和省略。句意：这一发现帮助研究人员得出结论，当这两种药物同时服用时，可能会导致心脏病。分析句子结构可知，空处省略主语the two drags，此处表示药被服用，所以空处需用一般现在时的被动语态：are taken，此处when引导的时间状语从句，主语与宾语从句主句一致，且含有be动词，所以此处be动词和主语被省略，所以可能从需用过去分词taken，故选A。
14.Bach died in 1750, but it was not until the early 19th century____ his musical gift was fully recognized.
A. while B. though C. that D. after
【答案】C
【解析】考查强调句。句意：巴赫死于1750年，但直到19世纪初期他的音乐天赋才被承认。强调句与not until连用，It be not until that …。故选C项。
注：not until 引起的时间状语置于句首时，句子的主谓应部分倒装。由 not until 引导的时间状语从句位于句首时，主句应部分倒装，从句语序不变。如：
Not until 1998 did he return to his hometown.
直到 1998 年他才回到家乡。
注意：当not until 引导的状语或状语从句用于强调句型时，句子的主语不倒装。如将上两句改为强调句应为：
It was not until 1998 that he returned to his hometown.
15.Never before ____________ seen anybody who can play tennis as well as Robert.
A. had she B. she had
C. has she D. she has
【答案】C
【解析】考查倒装。句意：在那以前，她从来没有看到一个人可能和Robert一样打乒乓球打得那么好。否定词never放在句首，主句要部分倒装，B、D排除，又因为是过去的情况对现在造成的影响，所以为现在完成时，是第三人称所以用has，所以用现在完成时，排除A，故选C。
第12讲特殊句式讲与练
【学习目标】
掌握特殊句式的几种形式。
【基础知识】
考点一 倒装句
1．全部倒装
(1)表示方向/方位、地点和时间的副词或介词短语，如here, there, now, then, up, down, in, away, off, out, back, on the wall, over there, under the tree, in front of等置于句首，且主语是名词而不是代词时。

要是明天不下雨，我们就可以去野餐。
考点二 强调句
1．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、宾语或状语等。
It is not how much we do but how much love we put into what we do that benefits our work most.
给我们工作带来最大益处的不是我们做了多少而是我们将多少热爱投入到我们所从事的事业中去。
2．强调句的几种句式
强调句的
特殊句式
构成
例句
一般
疑问句
Is/Was it＋被强调部分＋that/who＋句子其他部分？
Was it Tom who was to blame？
正是汤姆应负责任吗？
特殊
疑问句
特殊疑问词＋is/was it＋that＋句子其他部分？
The patient looks much better.What is it that has made him what he is today？
那个病人看上去好多了。是什么让他变成今天这样的呢？
not until
句式
It is/was not until ... ＋that＋句子其他部分
It was not until midnight that we got home because of traffic jams.
因为交通阻塞，直到半夜我们才到家。
not ...
but ... 句式
It is not ... but ... that ...
It is not quantity but quality that counts.
重要的不是数量而是质量。
3．用助动词强调谓语
如果要强调时态为一般现在时或一般过去时的肯定句中的谓语动词，我们在该动词前加助动词do, does或did。
①Many of the films are from the USA, but we do give awards to films from other countries.
许多电影来自于美国，但我们的确也给其他国家的影片颁奖。
②He did come to see you last Sunday, but you were out.
他上周日的确来看过你，但是你出去了。
[注意] (1)强调句型用于强调主语时，要注意谓语动词(原句)与该主语在人称和数上保持一致。
(2)强调句型的考点主要集中构成强调句型的基本元素that/who上，要明确的一点是，这两个词是不作成分的。
(3)强调句型不用于强调谓语、表语和定语；强调谓语时要用“助动词do/does/did＋动词原形”；但有时，为了表达的需要，用倒装结构对表语进行强调。
(4)注意区分强调句型与结构相似的含有that引导的定语从句的主从复合句(It is ... that ...)；区分的方法也很简单，就是看that是不是在句中作成分，作成分则不是强调句型。
4．强调句型的判断方法
判断一个句子是否是强调句型可采用还原法，即把it is/was和that/who去掉，如果剩下的部分仍然能组成一个完整的句子，该句就是强调句型，否则就不是。
①It was Wei Fang that/who met me in the park yesterday.
昨天在公园遇见我的人是魏芳。
(把It was和that/who去掉可以得到句子：Wei Fang met me in the park yesterday.此句句意和结构均完整，故原句为强调句)
②It is a pity that we missed the wonderful film.
遗憾的是我们错过了那部好电影。
(把It is和that去掉之后，无论是将a pity放在句首还是句末，句子均不合理，很显然原句不是强调句。本句中，it作形式主语，that引导主语从句。)
考点三 省略句
1．在when, while, whenever, till, if, unless, as if, though, than, as等引导的状语从句中，若谓语部分含有be动词，而主语又与主句主语相同或主语是it时，从句的主语和be动词常被省略。
①The experiment shows that proper amounts of exercise, if carried out regularly, can improve our health.
实验表明，如果有规律地进行适量运动，人们能强身健体。
②Work hard when (you are) young, or you'll regret.
少壮不努力，老大徒伤悲。
③While walking along the street, I heard my name called.
走在大街上时，我听见有人叫我的名字。
[注意] 特殊的省略结构：if省略结构，常作为插入语来处理。
if so 如果这样的话
if not 若非如此
if ever 如果曾经有的话
if necessary 如果有必要的话
if possible 如果可能的话
if any 如果有的话
If necessary，ring me. 如有必要，给我打电话。
If possible，let me know beforehand. 如有可能，事先通知我。
④Get up early tomorrow, if not (you don't get up early), you will miss the first bus.
明天早点起床，如果不的话，你将会错过头班公共汽车。
⑤Whenever (it is) possible, he will come to my help.
他会在任何可能的时候来帮助我。
2．I'm afraid, I think, I believe, I hope, I guess等作答句，后面跟so与not分别相当于肯定或否定，宾语从句可省去。
①—Do you think it will rain?
—I hope not/that it will not rain.
——你认为会下雨吗？
——我希望不要下。
②—Do you believe our team will win?
—I guess so.
——你相信我们队会赢吗？
——我猜会赢。
3．不定式省略，即单独使用不定式符号to。
(1)用来代替动词不定式后被省略的动词，常在be afraid/glad/happy, expect, forget, hope, intend, like, love, mean, prefer, refuse, seem, try, want, wish等的后边。
①I asked him to see a film, but he didn't want to.
我请他去看电影，但他不想去。
②—Will you join in the game?
—I'd be glad to.

(2)如果不定式中含有be, have, have been，通常保留be, have和have been。
③—Are you a sailor?
—No, but I used to be.
——你是海员吗？

(3)省略不定式符号to的情况。
a．当主语部分含有动词do的某种形式时，作表语的不定式可省略to。
④The only thing you have to do is press the button.
你唯一要做的事情就是按按钮。

⑤Brian had nothing to do but play computer games this afternoon.
今天下午布莱恩除了玩电脑游戏外无事可做。
c．当两个或两个以上的不定式并列时，后面的不定式符号to可省略，但表示对比关系时则不能省略。
⑥I'm really puzzled what to think of and express.
我真的不知道想什么和表达什么。
⑦It is easier to make a plan than to carry it out.
制订计划比执行计划容易。
d．在see, watch, hear, feel, observe, notice, look at, listen to等感官动词及使役动词let, make, have后作宾语补足语的不定式不加to，但当宾语补足语变为主语补足语时，不定式要加上to。

b．否定的祈使句，简短问句用will you。
c．let's和let us引导的祈使句：let's表“建议，征询”之意时，含听话者在内，故简短问句用shall we；let us表“建议、征询”之意时，不含听话者在内，故简短问句用will you。
①Let's go out for a walk after supper, shall we?
晚饭后我们散散步，好吗？
(2)must表示猜测时的反意疑问句
a．“must be”对现在的情况进行推测，按一般现在时或现在进行时的附加疑问句进行处理。
②He must be honest, isn't he?
他肯定很诚实，不是吗？
b．“must＋完成时”用来推测过去的动作，强调对现在的影响。句中没有表示过去时间的状语时，按现在完成时的附加疑问句来处理；如有明确的表过去的时间状语，按一般过去时处理。
③They must have gone there last night, didn't they?
昨天晚上他们肯定去那里了，不是吗？

(2)若陈述部分为“I/We don't think/believe/suppose/consider/ ... ＋宾语从句”，简短问句的主语和谓语与宾语从句的主语和谓语保持一致，且简短问句用肯定形式。
I don't think that you can do it, can you?

(3)若陈述部分为“主语(非第一人称)＋think/believe/suppose/consider/ ... ＋宾语从句”，简短问句的主语和谓语与主句的主语和谓语保持一致，而且简短问句是用肯定形式还是否定形式由主句决定。
They all think that English is very useful, don't they?
他们都认为英语很重要，是吗？

2．祈使句＋and/or/otherwise＋简单句(多用将来时)

4．There be句型
There be 句型表示“某时间/空间存在/有……”，there本身没有词义，be是谓语动词，be后面的名词/代词是主语。be可以有不同的形式，而且可以和情态动词连用。

【考点剖析】
考点一 倒装句中助动词、系动词、情态动词的缺失或主谓不一致
(1)【误】Only when he was 30 years old he begin to learn English.
【正】Only when he was 30 years old did he begin to learn English.
[解析] 当only和所修饰的状语位于句首时，引起部分倒装，根据语境可知，主句应用一般过去时，故倒装后应提取助动词did。
(2)【误】Next door to ours lives a foreign couple, who seem to have settled into life in China.
【正】Next door to ours live a foreign couple, who seem to have settled into life in China.
[解析] 此句是完全倒装结构，句子的真正主语是a foreign couple，故谓语动词用复数形式live。
[注意] 造成以上错误是因为对倒装句掌握不牢，建议加强对考点一的学习。
考点二 强调句型与三大从句(名词性从句、定语从句、状语从句)的误用
【误】It's more than half a century that my grandfather joined the Party and became a servant of the people.
【正】It's more than half a century since my grandfather joined the Party and became a servant of the people.
[解析] 此句是“It is＋一段时间＋since ...”句型。
[注意] 造成以上错误主要是对强调句型的判断方法(详参考点二第4点)认识不清而致，强调句型与三大从句的区别：
(1)与名词性从句区别：
强调句型去掉It is/was和that之后，句子结构仍然完整，语义通顺，而名词性从句却不能。
It is there that accidents often happen.(强调句)
正是在那儿经常发生事故。
It is a fact that English is being accepted as an international language.(名词性从句)
英语作为一门国际语言正被广为接受是个事实。
(2)与定语从句区别：
强调句中that没有语义，且不作任何成分，而定语从句中that为关系代词，在从句中充当主语、宾语或表语。
It is novels that Miss William enjoys reading.(强调句)
威廉小姐喜欢读的是小说。
It is a question that needs careful consideration.(定语从句)
这是一个需认真考虑的问题。
(3)与时间状语从句区别：
强调句型去掉It is/was和that后，结构完整，而It is ... when ... 中，it指代时间。
It was at six o'clock that I got up today. (强调句)
今天我是在六点起的床。
It was six o'clock when I got up today. (时间状语从句)
今天我起床时已六点了。
考点三 省略句中to的缺失
【误】She was reading in bed, and her mother told her not.
【正】She was reading in bed, and her mother told her not to.
[解析] 动词不定式在like, love, care, want, hope, wish, expect, prefer, refuse, decide, mean, intend, try, promise等动词后作宾语时，为了避免重复，常常省略不定式后的内容，但要保留不定式符号to。
[注意] 加强对考点三“不定式的省略”部分的学习。
考点四 感叹句中what与how的误用
【误】You simply can't imagine how a wonderful time we have been having!
【正】You simply can't imagine what a wonderful time we have been having!
[解析] 句意：你们简直无法想象我们过得有多么愉快！
[注意] 加强对考点四第3点“感叹句”的学习，要熟知其结构，了解how修饰的中心词为形容词或副词，而what修饰的中心词为名词。
考点五 祈使句、反意疑问句中的常见错误
(1)【误】They don't believe she is an engineer, isn't she?
【正】They don't believe she is an engineer, do they?
[解析] 当主句的主语为二、三人称时，其反意疑问句应与主句一致，与从句无关。
(2)【误】Study hard, or you'll succeed.
【误】Studying hard, and you'll succeed.
【正】Study hard, and you'll succeed.
【正】Studying hard, you'll succeed.
[解析] 本句要么用“祈使句＋and/or/otherwise＋简单句”结构，因逗号前后为并列递进关系，故应用and；要么用非谓语动词作状语的形式，但必须有主句，故将Study改为Studying，并将and去掉。
[注意] 反意疑问句的错误主要集中在对肯定、否定及人称把握不准上；祈使句的错误主要集中在“祈使句＋and/or/otherwise＋简单句”的句型与非谓语动词的混淆上。应加强对考点四第1点和第2点的学习。
【真题演练】
1．(2019·天津高考)The professor warned the students that on no account ________ they use mobile phones in his class.
【答案】should
【解析】考查虚拟语气。warn的宾语从句用should+动词原形。句意：教授警告学生在他的课堂任何情况下都不能使用手机。
2．(2018·全国卷Ⅱ)Diets have changed in China—and so too ________ its top crop.
【答案】has
【解析】考查倒装句。so+助动词、情态动词+主语，表示…也。
3．(2018·天津高考)It was only when the car pulled up in front of our house ________ we saw Lily in the passenger seat.
【答案】that
【解析】考查强调句。句意：只有当那辆车子停在我们房子前面，我们才看见莉莉坐在乘客的座位上。
4．(2017·江苏高考)________ it not for the support of the teachers, the student could not overcome her difficulty.
【答案】Were
【解析】考查虚拟语气。本句省略了if,句意：如果不是因为老师的支持，这个学生是不可能克服困难的。
5．(2016·全国卷Ⅱ)It could be anything—gardening, cooking, music, sports—but whatever it is, ________ (make) sure it's a relief from daily stress rather than another thing to worry about.
【答案】make
【解析】考查祈使句。句意：它可以是任何事情—园艺，做饭，音乐，运动—但是无论是什么，一定要确保它是日常生活压力的一种缓解，而不是另一种担忧。
解题两步骤
第1步 注意分析句式结构，确定为何种特殊句式。
第2步 根据特殊句式的结构特点填入适当的词。
1．(2020·全国卷Ⅰ)Turning to a page in your journal to your list of strengths and achievements.
__________________________________________________________________
【答案】Turning→Turn
【解析】考查祈使句。
2．(2018·北京高考)In any unsafe situation, simply pressing the button and a highlytrained agent will get you the help you need.
__________________________________________________________________
【答案】pressing→press
【解析】考查祈使句。
遇到特殊句式，要注意主谓一致、强调句、倒装句、省略句、感叹句等的构成特点。
[温馨提示] 特殊句式虽种类繁多，但在高考的语法填空和短文改错中出现的频率并不是很高，大部分为对固定句式结构的考查。在复习时，认真研读例句，勤练高考真题和模拟题，熟练掌握基础知识，便可轻松应对。
【过关检测】
1._____________ basic first-aid techniques will help you respond quickly to emergencies.
A. Known B. Having known
C. Knowing D. Being known
【答案】C
【解析】考查动名词作主语。句意：了解基本的急救知识可以帮助您快速应对紧急情况。分析句子成分，谓语是will help，所以前面的是主语，用动名词做主语，故选C项。
2.Though________ to see us, the professor gave us a warm welcome.
A. surprising B. to surprise
C. being surprised D. surprised
【答案】D
【解析】考查状语从句的省略。句意：教授见到我们虽然很惊讶，但还是热情地欢迎了我们。be surprised to do，对做某事很惊讶，在though引导的让步状语从句中，当从句主语与主句主语一致且含有be的某种形式时，可省略从句的主语和be，本句完整形式为：Though he was surprised to see us，相当于省略了he was，故选D。
3.He doesn’t think that the plan is practical, _____?
A. does he B. doesn’t he C. is it D. isn’t it
【答案】C
【解析】考查反意疑问句。句意：他认为这个计划不切实际，是吗？A. does he他是吗；B. doesn’t he 他不是吗；C. is it它是吗；D. isn’t it它不是吗。分析可知，句子句式属于“I(we) don’t think +that从句”，在该句式中，从句为否定意义，反意疑问句部分的系动词/助动词/情态动词和主语要与that从句保持一致且用肯定式，因此在本题中，反意疑问句应是与从句中的系动词“is”保持一致，主语与“the plan”保持一致，用第三人称单数“it”代替，故反意疑问句为：is it。故选C项。
4.China’s image is improving steadily, with more countries ________ its role in international affairs.
A. recognizing B. being recognized

5.When ______ different cultures, we often pay attention only to the differences without noticing many similarities.
A. being compared B. comparing
C. Compared D. having been compared
【答案】B
【解析】考查状语从句省略。句意：当比较不同的文化的时候，我们通常总注意到它们之间的区别而没有注意到它们之间的相似之处。当从句省略主语的时候，暗指的主语必须和主句的主语一致，“When ” 后没有主语，所以它暗指的主语必须是后面主句的主语，就是“'we”，也就是说从句里的compare 的主语是we，表示“我们在比较”, compare与句子we构成主动关系，使用动词的现在分词，且与主句主语pay attention to同时发生，用一般式。A项是被动式；C项是过去分词，D项是完成被动式，均表示被动。故B项正确。
6.In any unsafe situation, simply ________ the button and a highly-trained agent will get you the help you need.
A. press B. to press
C. pressing D. pressed
【答案】A
【解析】考查祈使句。句意：在任何不安全的情况下，仅仅摁一下这个按钮，一个训练有素的特工就会使你得到你需要的帮助。and是连词，连接并列结构，and后面是一个句子，那么，前面也应是句子，选项中只有动词原形可以构成祈使句，其余的都是非谓语动词，无法构成句子。故A选项正确。
点睛：祈使句+and/or+陈述句是一种常见结构。当前后两部分间为承接关系时，用and；前后意思为相反关系时，用or。该句式中的陈述句部分常用一般将来时态。
7.I wish I ________ football game on TV last night, but I went to a friend's birthday party.
A. watched B. had watched C. would watch D. were watching
【答案】B
【解析】考查虚拟语气。句意：我希望我昨晚看了电视上的足球比赛，但是我去了一个朋友的生日聚会。分析可知，wish后的宾语从句，应用虚拟语气，由时间状语last night可知该句是对过去发生事情的虚拟，结构为：wish + 主语 + had + 过去分词。故选B项。
8.It was only after experiencing the failure________ he began to train seriously and he won the championship in the 400-metcr freestyle a year later.
A. when B. whether C. that D. which
【答案】C
【解析】考查强调句。句意：在经历了失败后，他开始认真训练，并在一年后赢得了400米自由泳冠军。分析句子可知，该句去掉It was和设空处仍然是完整的句子，由此可知此处考查该强调句，结构为：It is + 被强调部分 + that/who（强调人时可用who）...，该句被强调部分为状语，只能用that。故选C项。
9.I feel it is you as well as your wife that ______ for your son's bad performance at school.
A. are to blame B. is to be blamed
C. are to be blamed D. is to be blamed
【答案】A
【解析】考查强调句中的主谓一致。句意：你儿子在学校成绩不好，我觉得你和你妻子都应该受到责备。as well as连接两个并列主语，谓语动词要和前一主语保持一致，因此be动词用are；动词blame不用被动语态，常用be to blame主动式表被动意义。故选A项。

11.I wonder when it was_______ you came to realize ________his words meant.
A. that; what B. what; that C. what; what D. that; which
【答案】A
【解析】考查强调句及宾语从句。句意：我想知道究竟是什么时候你意识到他所说的话的真正意思是什么。本句是一个多重复合句。I wonder后是when引导的强调句式的特殊疑问句，可以复原为“It was (when) that you came to realize…”以协助理解，所以空一用强调句的引导词that；及物动词realize后接宾语从句，该从句中动词meant后的宾语缺失，即空二应填入能充当meant宾语的疑问词来引导宾语从句，结构为meant sth.(what)，故what正确。故选A。
12.Only when _______ be possible to sign the papers.
A. does the lawyer come with it B. the lawyer comes will it
C. has the lawyer come it will D. the lawyer comes it will

13.This discovery helped researchers conclude that these two drugs, when ___ together, could lead to heart disease.
A taken B. taking
C. to take D. having taken
【答案】A
【解析】考查非谓语动词和省略。句意：这一发现帮助研究人员得出结论，当这两种药物同时服用时，可能会导致心脏病。分析句子结构可知，空处省略主语the two drags，此处表示药被服用，所以空处需用一般现在时的被动语态：are taken，此处when引导的时间状语从句，主语与宾语从句主句一致，且含有be动词，所以此处be动词和主语被省略，所以可能从需用过去分词taken，故选A。
14.Bach died in 1750, but it was not until the early 19th century____ his musical gift was fully recognized.
A. while B. though C. that D. after
【答案】C
【解析】考查强调句。句意：巴赫死于1750年，但直到19世纪初期他的音乐天赋才被承认。强调句与not until连用，It be not until that …。故选C项。
注：not until 引起的时间状语置于句首时，句子的主谓应部分倒装。由 not until 引导的时间状语从句位于句首时，主句应部分倒装，从句语序不变。如：
Not until 1998 did he return to his hometown.
直到 1998 年他才回到家乡。
注意：当not until 引导的状语或状语从句用于强调句型时，句子的主语不倒装。如将上两句改为强调句应为：
It was not until 1998 that he returned to his hometown.
15.Never before ____________ seen anybody who can play tennis as well as Robert.
A. had she B. she had
C. has she D. she has
【答案】C
【解析】考查倒装。句意：在那以前，她从来没有看到一个人可能和Robert一样打乒乓球打得那么好。否定词never放在句首，主句要部分倒装，B、D排除，又因为是过去的情况对现在造成的影响，所以为现在完成时，是第三人称所以用has，所以用现在完成时，排除A，故选C。
