三、Must be somebody waiting for you. 一定是有人在等你。

22、倒装
一、全部倒装
全部倒装是指将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。常见的结构有：
1. here, there, now, then, thus等副词置于句首， 谓语动词常用be, come, go, lie, run。例如：
1) There goes the bell. 铃声渐渐消失了。
2) Then came the chairman. 然后主席就来了
3) Here is your letter. 这是你的信。
2. 表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。例如：
1) Out rushed a missile from under the bomber. 轰炸机下面发出了一颗导弹。
2) Ahead sat an old woman.
注意：上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。例如：
1) Here he comes. 他来了。
2) Away they went. 他们走了。
二、部分倒装
部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。
1. 句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。例如：
1) Never have I seen such a performance. 我从来没看过这样的表演。
2) Nowhere will you find the answer to this question. 你在哪儿都不会找到这个问题的答案。
3) Not until the child fell asleep did the mother leave the room. 妈妈直到孩子睡着才离开房间。
注意：当Not until引出主从复合句，主句倒装，从句不倒装。
注意：如否定词不在句首不倒装。例如：
1) I have never seen such a performance.我从来没看过这样的表演。
2) The mother didn't leave the room until the child fell asleep.妈妈直到孩子睡着才离开房间。
2. 带有否定意义的词放在句首，语序需要部分倒装。常见的词语有：not , never , seldom , scarcely , barely , little , at no time , not only , not once , under on condition , hardly … when , no sooner …than …等。例如：
1) Not only did he refuse the gift, he also severely criticized the sender. 他不仅拒收了礼品，还狠狠批评了送礼的人。
2) Hardly had she gone out when a student came to visit her. 她刚要出门时有个学生来找她。
3) No sooner had she gone out than a student came to visit her. 她刚要走时一个学生来看她。
注意：只有当Not only… but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语，不可用倒装结构。例如：
Not only you but also I am fond of music. 我和你都喜欢音乐。
3. 表示“也”、“也不” 的so, neither, nor放在句首时，句子作部分倒装。例如：
1) Tom can speak French. So can Jack. Tom能说法语，我也能。
2) If you won't go, neither will I. 如果你不去，我也不去。
注意：当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为“的确如此”。例如：
1) Tom asked me to go to play football and so I did. Tom让我去踢足球，我去了。
2) ---It's raining hard. ---So it is. ---雨下得很大。 ---的确很大。
4. only放在句首，强调状语(副词，介词短语或状语从句等)，全句语序要部分倒装。例如：
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. 他被请了三次才来开会。
注意：如果句子为主从复合句，则主句倒装，从句不倒装
Only when he is seriously ill, does he ever stay in bed. 他只有病得非常严重时才会卧床休息。
三、as, though 引导的倒装句
as / though引导的让步从句必须将表语或状语提前 (形容词， 副词， 分词， 实义动词提前)。此时应注意：1) 句首名词不能带任何冠词;2) 句首是实义动词， 其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。例如：
Try hard as he will, he never seems able to do the work satisfactorily. 尽管他愿意努力工作，但是他好像从来都不能令他的工作満意。
注意： 让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。
四、其他部分倒装
1. so… that 句型中的so 位于句首时，需倒装。例如：
So frightened was he that he did not dare to move an inch. 他害怕得动都不敢动。
2. 在某些表示祝愿的句型中，例如：
May you all be happy. 望大家开心愉快。
3. 在虚拟语气条件句中从句谓语动词有were, had, should等词，可将if 省略，把 were, had, should 移到主语之前，采取部分倒装。例如：
Were I you, I would try it again. 如果我是你，我就再试一次。
23、强调
一、强调句型
为了强调句子的某一成分(通常是主语、宾语、或状语)，常用强调句型：It is (was) +被强调部分+that(who)… 表示强调的 it 在句子中作主句的主语;被强调部分可以是主语，宾语，表语或状语;强调的主语如果是人，that和who都可用。如：
Last night I saw a film in the Youth Palace.
强调主语：It was I that (or: who) saw a film in the Youth Palace last night.
强调宾语：It was a film that I saw in the Youth Palace last night.
强调地点状语：It was in the Youth Palace that I saw a film last night.
强调时间状语：It was last night that I saw a film in the Youth Palace.
另外，还要注意下面几点：
1)在强调主语时，that 后的谓语动词要与被强调者保持人称和数的一致。如：
It is I who am a teacher.
2)即使被强调的主语是复数，主句中的谓语动词也用单数。如：
It is they who often help me with my lessons.
3)在强调时间、地点、原因或方式状语时，不能用when，where，why或 how ，而要用that 。如：
It was because her mother was ill that she didn't go with us.
It was only when I reread his poems recently that I began to appreciate their beauty.
It was the house that the murder happened.
4)在强调not … until 结构中由 until 短语(或从句)表示的时间状语时，要用固定的强调句型：It is(was) not until ……that…… 注意此时原句的not…until要变成not until ，that 从句中的谓语动词要用肯定式。如：
My father didn't come home until 12 o'clock last night.
It was not until 12 o'clock last night that my father came home.
I didn’t realize she was a famous film star until she took off her dark glasses.
It was not until she took off her dark glasses that I realized she was a famous film star.
5)原句的谓语动词如果是现在或将来的各种时态，用It is…that (who)…;如果原句谓语动词是过去各种时态，则用It was… that(who)…
6)在强调一般疑问句中的某一成分时，主句要用一般疑问句的语序。that后面的原句其余部分在移走了被强调部分后词序及词形都不可以改动。如：
Did this happen in Beijing?
Was it in Beijing that this happened?
7)特殊疑问句中只有疑问词可以强调，其强调结构是“疑问词+is (was) it that……? " 如：
Where were you born?
Where was it that you were born?
8)强调句型容易和句型It is/was+名词+that名词从句混淆。如果把构成强调句型结构的词It is (was) … that(who)… 去掉，被强调部分归位后，应该能够形成一个完整 的句子(这也是判断是否是强调句型的方法)。但后者的It is/was…that 是不可去掉的，否则that前的名词就找不到位置，原句也不再成立，如下面这个句子如去掉It is/was…that就不再完整：
It was the rule of the school that the pupils should wear their school uniforms.
强调句型还容易跟It is/was+形容词+that名词从句这一句型混淆。如：It is clear (obvious, true, possible, certain……) that …… 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为”清楚(显然， 真的， 肯定…)”是主语从句最常见的一种结构。
It is very clear that he’s round and tall like a tree.
That he’s round and tall like a tree is very clear.
9)强调句可以用作宾语从句。如：
He told me that it was because he was late for class that he was punished.
I really can’t remember where it was that I first met the man.
10)强调句型可有如下变体：It is/was变成“情态动词+be”。如：
It may be my bike that he is riding.
It must have been the manager that spoke to you.
11)与疑问词连用构成特殊疑问句和感叹句。如：
Whom was it that Mr. Smith saw in the park yesterday?
Why is it that silver is not widely used as a conductor?
What a beautiful picture it is that you have drawn!
12)被强调的名词或代词可带有一个定语从句。如：
Was it Bill, who plays football well, that helped the blind man cross the road?
It was in the school, where(or：in which) I once studied, that we hold a party.
Was it in the house, which we visited last year, that the murder happened?
二、用助动词do或其变化形式does，did来强调句中谓语动词，用来加强陈述句和祈使句的语气，译作“的确”，“一定”，“确实”。如：
He did send you a letter last week.
We’re pleased that she does intend to come.
Do write to me when you get there.
三、用倒装句来加强语气。如：
Only in this way can we solve this problem.
Never will China be the first to use nuclear weapons.
Proud as these nobles are, they are afraid to see me.
In front of the farmhouse there sat a little boy.
四、用形容词， 副词或者否定词very, never, ever, even, still , single，simply, just ,only, too等来表示强调。如：
At that very monent he heard a cry for help.
I can't even remember the name of that old friend of mine.
Not a single person has been in the office this afternoon.
You are the only person here who can speak Chinese.
This is just what I wanted.
五、用what引导的名词性从句或wh-疑问词+ever构成的复合词引导的状语从句来强调从句中的主语，宾语或状语等。如：
What Mary does every day is to give piano lessons.
Whenever you come to me, you can come right in.
六、反复使用同一个词来加强语气 ，可反复使用词的一般是动词， 副词，形容词和名词。如：
He worked (and) worked until late at night.
They walked for miles and miles.
I'll never, never forget you.
七、 用“at all”，“in every way”，“in no way”，“by all means”，“by no means”，“only too”，“all too”，“but too”，“in heaven”，“in the world”，“in hell”，“on earth”，“under the sun”等来加强疑问或否定语气。如：
Where in the world did you go just now ?
What on earth are you doing?
She's not in the least angry with me.
The clerk is not at all fit for the post.
八、用感叹句来表示强烈的感情，突出说话人的情感。如：
How interesting a story it is!
九、 用反身代词表示强调 。如：
I myself will see her off at the station.
You can do it well yourself.
十、用破折号、黑体字也可以表示强调，加强语气：
It's because of hard work—ten years of hard work.
24、虚拟语气
1) 概念
虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。
2) 在条件句中的应用
条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
真实条件句
真实条件句用于陈述语气，假设的情况可能发生，其中 if 是如果的意思。
时态关系
句型：条件从句主句
一般现在时 shall/will + 动词原形
If he comes, he will bring his violin.
非真实条件句
1)时态：可以表示过去，现在和将来的情况。它的基本特点是时态退后。
a.同现在事实相反的假设。
句型 ：条件从句主句
一般过去时should( would) +动词原形
If they were here, they would help you.
b.表示于过去事实相反的假设。
句型：条件从句主句
过去完成时should(would) have+ 过去分词
If she had worked harder, she would have succeeded.
The rice would not have been burnt if you had been more careful.
If my lawyer had been here last Saturday, he would have prevented me from going.
If he had come yesterday, I should / would have told him about it.
含义：He did not come yesterday, so I did not tell him about it.
If he had not been ill and missed many classes, he would have made greater progress.
含义：He was ill and missed many lessons, so he did not make greater progress.
c.表示对将来的假想
句型：条件从句 主句
一般过去时should+ 动词原形
were+ 不定式 would + 动词原形
should+ 动词原形
If you succeeded, everything would be all right.
If you should succeed, everything would be all right.
If you were to succeed, everything would be all right.
混合条件句
主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。
If you had asked him yesterday, you would know what to do now.
(从句与过去事实相反，主句与现在事实相反。)
If it had rained last night (过去), it would be very cold today (现在).
虚拟条件句的倒装
虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。
Were they here now, they could help us.
=If they were here now, they could help us.
Had you come earlier, you would have met him
=If you had come earlier, you would have met him.
Should it rain, the crops would be saved.
=Were it to rain, the crops would be saved.
注意：
在虚拟语气的从句中，动词'be'的过去时态一律用"were"，不用was， 即在从句中be用were代替。
If I were you, I would go to look for him.
如果我是你，就会去找他。
If he were here, everything would be all right.
如果他在这儿，一切都会好的。
特殊的虚拟语气词：should
1) It is demanded / necessary / a pity + that…结构中的主语从句的谓语动词要用should 加动词原形， should 可省略。
句型：
(1)suggested
It is(2)importantthat…+ (should) do
(3) a pity
(1)suggested, ordered, proposed, required,demanded, requested, insisted;+ (should) do
(2)important, necessary, natural, strange
a pity,a shame,no wonder
(3)It is suggested that we (should) hold a meeting next week.
It is necessary that he (should) come to our meeting tomorrow.
2)在宾语从句中的应用
在表示命令、建议、要求等一类动词后面的从句中。
order, suggest, propose, require, demand, request, insist, command, insist + (should) do
I suggest that we (should) hold a meeting next week.
He insisted that he (should ) be sent there.
注意：如suggest, insist不表示“建议” 或“坚持要某人做某事时”，即它们用于其本意“暗示、表明”、“坚持认为”时，宾语从句用陈述语气。
The guard at gate insisted that everybody obey the rules.
判断改错：
(错)You pale face suggests that you (should) be ill.
(对)Your pale face suggests that you are ill.
(错)I insisted that you ( should) be wrong.
(对)I insisted that you were wrong.
3)在表语从句，同位语从句中的应用
在suggestion, proposal, idea, plan, order, advice等名词后面的表语从句、同位语从句中要用虚拟语气，即(should)+动词原形。
My idea is that we (should) get more people to attend the conference.
I make a proposal that we (should) hold a meeting next week.
wish的用法
1)用于wish后面的从句，表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为：
I wish I were as tall as you.我希望和你一样高。
He wished he hadn't said that. 他希望他没讲那样的话。
I wish it would rain tomorrow. 我希望明天下雨就好了。
2)Wish to do表达法。
Wish sb / sth to do
I wish to see the manager. = I want to see the manager.
I wish the manager to be informed at once. (= I want the manager to be informed at once.)
比较if only与only if
only if表示“只有”;if only则表示“如果……就好了”。If only也可用于陈述语气。
I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。
If only the alarm clock had rung.当时闹钟响了，就好了。
If only he comes early.但愿他早点回来。
It is (high) time that
It is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。
It is time that the children went to bed.
It is high time that the children should go to bed.
need“不必做”和“本不该做”
didn't need to do表示：过去不必做某事， 事实上也没做。
needn't have done表示：过去不必做某事， 但事实上做了。
John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽，所以她不必步行回家了。
