英语语法专题复习-特殊句式
I.倒装句（有两种考法）
一．.完全倒装
将谓语动词全部提到主语之前。常见情况有：

There goes the bell.
Here comes the bus.
Out rushed the children.
Away went the boy.
【注意】当主语是人称代词时，主语语序不变。
Here it is.
Away he went.
2. 地点状语＋谓语＋主语；此时，地点状语为标志词，谓语动词为不及物动词。
South of the river lies a small factory.
From the valley came a frightening sound.
3. such, then, now, thus, the following 放句首时，谓语动词多为come, follow, begin, end, be。
Such are the facts.
The following is the answer to the question.
Now comes your turn.
4. There be/lie/exist/ stand/live ＋主语＋…(there be 句型)
There is a tall building on the top of the mountain.
There stands an ancient tower on the top of the mountain.
5. 表语＋系动词＋主语；表语可以是介词短语，形容词或分词。
【注意】若主语较长，可还原为正常语序即：主语＋系动词＋表语。
Present at the party were Mr. Green and many other guests.
Seated on the ground are a group of young men.
Gone are the days when we used the “foreign oil”．

7. 用于某些表示祝愿的句子中。
Long live the People's Republic of
二、部分倒装
将情态动词、助动词、be提到主语前 (可以还原为正常的语序，检验倒装句是否正确。)
1.含有否定意义的副词或短语放句首时,如：few, little, never, not, not until, nowhere, rarely, seldom, hardly/scarcely...when,no sooner…than,not only…(but also), at no time, by no means等。
Little does he know about the news. 他对这消息知之甚少。
By no means can he catch up in such a short time. 他根本不可能在这么短的时间里赶上来。
①若原句中没有助动词，必须根据谓语动词的具体时态来确定相应的助动词do, does 或did。
He is active in personality, and he seldom stays indoors.(无助动词)
He is active in personality, and seldom does he stay indoors.(添加does)
②not only…but also连接两个并列主语时不可倒装。只有在连接两个句子且将not only所连接的句子提到句首时，才可用倒装，but also后面的句子不倒装。
Not only children but also adults are interested in the film Harry Potter. (连接并列主语不倒装)
③在“hardly/scarcely…when”和“no sooner…than”结构中主句用过去完成时,从句用过去时
I had hardly got to the airport when the plane took off.
Hardly had I got to the airport when the plane took off. (注意谓语动词的形式)
④not until提前时，必须将not until后面的全部内容提前，而不仅仅是not until这两个词。
The villagers did not realize how serious the pollution was until all the fish died in the river.
Not until all the fish died in the river did the villagers realize how serious the pollution was. (将until后面的全部内容提前)
⑤neither…nor… 句型中两个句子都需要部分倒装。
Neither did I want to see the film nor did I buy the ticket.
(＝I neither wanted to see the film nor bought the ticket.)
2. so/as/neither/nor 为标志词放在句首；
①表示前面所说的肯定情况也适合于另一人或物,so/as ＋be (助动词或情态动词) +主语。
— I've got an enormous amount of work to do.——我有大量的工作要做。
— So have
He believed, as did all his family, that you were innocent.他，和他全家人一样，相信你是无辜的。
②表示前面所说的否定情况也适合于另一人或物,neither (nor)＋be (助动词或情态动词)主语。If she doesn't agree to the plan, neither will Tom.如果她不同意这个计划，Tom也不会同意。
①“so ＋主语＋助动词”表示对上文肯定的内容加以肯定或赞同，意为“的确如此”；
— It's raining hard. ——天下着大雨。
— So it is.——是的。
②“主语＋did ＋so”表示：“主语”这样做了。
Tom asked me to go to play football with him and I did so.Tom要我去踢足球，我去了。
3. only ＋ 状语(或状语从句)＋助动词/系动词/情态动词＋主语＋谓语其他部分
状语可以是副词或介词短语和状语从句。
Only in this way can you learn English well. 你只有用这种方法才能学好英语。
Only after being asked three times did he come to the meeting. 他被请了3次才来开会。
only之后跟的不是状语时不可倒装。下面两句中的only跟的就是主语：
Only that boy can work out the problem. 只有那个男孩才能解答出这个问题。
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，即Had/Were/Should＋主谓＋谓语其他部分＋主句。
Had I attended the meeting, I would have met Jim.
5. 在 “so…that”和“such…that”结构中，将“so＋adj.”和“such＋n.”提到句首时。
So terrible was the storm that the whole roofs were blown off.
暴风雨如此厉害，整个屋顶都被吹掉了。
Such a clever boy was Jack that he was able to work out all these difficult problems.
杰克是如此聪明的孩子，他能解答所有这些难题。
【疑难点击】
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. 标志词as: “尽管 /虽然”句式：
(1)表语(形容词/名词)＋ as/though ＋ 主语＋ 系动词，主句。
【注意】名词前不加任何冠词。

2013届高考英语语法专题复习-特殊句式解析
2012高考题
1.答案：C考点：部分倒装。
解析：句首有关键词Never，否定词提前到句首，句子部分倒装。排除B,D。再根据句子时态，应用现在完成时，故选C。
2.答案：D考点：短语考察。解析：句意为他似乎给人们留下一种在巴黎玩得不开心的印象______他玩得很开心。前后句有转折之意，故选D恰恰相反。A首先，B此外，C结果是。
3.【答案】B【解析】此处or表示“否则”。句意：你必须躲开，否则卡车过不去。
【考点定位】考查并列连词。
4.【答案】C【解析】当表示后者与前者具有相同特征的时候，后者用倒装的形式；肯定用so，否定用nor或neither构成。根据后面一句中的I can’t stand all this rain可知，此处与上一句中的I’m sick and tired of the weather表达同样的感受，因此应该用So am I，表示“我也是”。句意：---我不了解你。我讨厌这种天气。---我也是。我无法忍受整天下雨。
【考点定位】考查倒装句的用法。
5. 【考点】虚拟语气中的情态动词【答案】D【解析】本句是一个倒装句，可还原为：if they had known what was coming next, they might have had second thought。根据had known提示，可知是与过去事实相反，因此虚拟语气主句中应该用would/might +have done，由此可见答案D符合语境。【难度】较难
6. 【考点】特殊句式—反义问句【答案】A【解析】根据前面there be 句里含有否定意义的词little，所以反意疑问句用肯定形式，其主谓应与陈述部分的主谓保持一致，故选A项。
7 [2012湖南高考真题35]||D||本题考查主谓一致，第一空的主语evidence为不可数，所以排除A、C；第二空主语为increasing use也是不可数，所以选D。主谓一致 不可数名词/动名词/含介词短语的部分作主语
8. [2012湖南高考真题30]||B||本题考查强调句。把it was及空去掉，可转换为一个完整的句子。且这是表示“直到……时才”的句型之一：it was not until … that …。复合句 强调句型that
9.【考点】特殊句式—倒装结构 【答案】C【解析】空白处前为否定词“nor”位于句首，句子应该使用部分倒装结构，而且根据语境空白处应使用一般将来时，C选项符合题意。因此，正确答案为C选项。
10.【考点】特殊句式—强调句型【答案】B 【解析】句子虽然比较长，但是其主干为强调句型，是对“80 years before Christopher Columbus crossed the Atlantic”进行了强调，由此可知，空白处应该填写“that”。因此，正确答案为B选项。【难度】一般
11.【考点】特殊句式—倒装。【答案】D【解析】Not until位于句首时句子要倒装，consider having a holiday abroad这个动作发生在retire之后，所以用一般过去时。【难度】一般
12.【答案与解析】 A 本题考查并列连词。题干句意为：在学校，一些学生很活跃而一些却很害羞，然而他们都可能彼此成为好朋友。根据句意选while，表示两个分句中两种情况的对比。
13.【答案与解析】 C 本题考查倒装句。nor位于句首引起部分倒装，排除B、D；再根据句意“这并不是（关于）我的故事，它也不是故事的全部。我的故事的结局不同。”选代词it。故答案选C。
14.[2012陕西卷]【答案与解析】B 考查动词时态和主谓一致。主语中心词是the basketball coach，是单数，根据shortly after the match可以推断出题干时态是一般过去时，故选B。
15. A祈使句考点，用动词原形。
16.A倒装句
其它考题
【解析】
1. B 表示地点的介词短语置于句首，句子应完全倒装。故选B。

3. B 答句中省略了主语it，即It doesn't matter。
4. D If possible 为If it is possible 的省略形式，其他选项不符合题意。
5. D go without…意为“没有……也能过活”与句中hardly连用指价格每天都在上涨。
6. C not until 引导的时间状语(从句)置于句首主句要部分倒装。
7. C 动词不定式省略时可省略to 后的内容，但要保留不定式符号to。当to 后为be动词或助动词have时，要保留be和have。
