8、分句。强调的原因状语也只能用because引导的。 It was although it was raining that he went out. () It is while Tom is an English that Xiao Li is a Chinese. () It was because he was late for work that the boss fired him. ()3.用It is 还是It was，取决于原句时态。 He teaches English. It is English that he teaches. Peter lost his way in

9、 the woods. it was in the woods that Peter lost his way.4.这种强调句的句型转变都是在强调局部上进行。 1一般疑问句只需把is/was提前。 It was in the street that I saw her.Was it in the street that I saw her? 2)否认句那么是在is/was 后加not。 It was in the street that I saw her. It was not in the street that I saw her. 3)它的特殊疑问句只需在一般疑问句前加上特殊疑问词。

11、 your shoes under the bed. (对划线局部强调) It may be under the bed that you have put your shoes.将此句变成一般疑问句 Can it be under the bed that you have put your shoes? It may be under the bed that you have put your shoes.将此句变成否认句 It cant be under the bed that you have put your shoes. It may be under the bed that

12、 you have put your shoes.(对划线局部提问) Where can it be that you have put your shoes? 5.not.until.句型的强调句:(注意否认的转移) 其结构为: It is /was not until +被强调局部 + that + 其他成分。 I didnt leave until he came back. It was not until he came back that I left. 6.解题说明： 1强调句型与that从句作主语，it作形式主语的区别：关键是看把it is/was.that.去掉后，剩余的成分

13、能否组成一个完整的句子。能就是强调句式，否那么就不是。 It is surprising that he didnt come. (主语从句) It was he that didnt come. (强调句式) 2强调句型与定语从句的区别：关键也是看去掉标志后能否复原成一个完整的句子。 It is the first time that_. It was for the first time that _. A. I have heard the song B. I heard the song 解析：第一句是现在完成时的惯用句型，实际上是一个定语从句，that是一关系副词，相当于when,代

14、指先行词the first time。所以第一句选A。 第二句是强调句型，强调时间状语for the first time(首次，第一次)，常用于一般过去时。所以第二句B。 It is _that he has been to London.Yes,he doesnt travel abroad a lot.A. the second time B.many times C.twice D. for the first time 解析：根据下文答语，原句应为：he has been to London twice.是在对twice进行强调。此句不同与It is the second time

15、that he has been to London。所以选C。 3)根据具体语境情况,而不是单独的一个句子来处理. -Where did you meet Mr. Smith? -It was in the hotle_he stayed. A. that B. where C.which D. for which 解析: 此题很容易被看成是一个强调句式,而实际上是在答复where,答语中的it代指地点.这是一个定语从句,所以应选B 项。 4强调句型在宾语从句时，要注意语序的变化。 Who was it that swept the floor? We dont know. We dont

16、know who it was that swept the floor. 5)与时间相关的几个句型： It was + 时间名词 + when. 时间状语从句 It was +介词 + 时间名词 + that. (强调句型) It was +时间段过去时间+ that. (强调句型) It was 2 oclock B I came home. It was at 2 oclock_A_ I came home. It was morning _B_ I came home. It was this morning _A_ I came home. It was 3 days ago _A_

17、 I came home. It is /has been + 时段 + since从句一般过去时 It was + 时段 + before从句一般过去时 It +将来时 + 时段 + before从句一般现在时 It is /has been three years since I began to learn English.It was three years ago that I began to learn English. 强调 It was three months before she came back from Beijing.It was three months lat

18、er that she came back from Beijing. (强调) 6谓语动词的强调不用此结构，而是在谓语动词前加助动词do,does或did。 She did write a letter to her mother last week. Do come to my party! 【真题演练】 1It was in New Zealand _ Elizabeth first met Mr. Smith. (08全国卷II 20)A. that B. how C. which D. when 【解析】：A此题是对地点in New Zealand的强调，为强调句的根本句式。2It

21、倒装。例如：l They kept the milk for themselves.The milk they kept for themselves. For themselves they kept the milk.The milk did they keep for themselves.(错)l Out of the package _ a paper and gave it to my father.A. he drew B. did he drew C. drew he D. he has drawn答案：A。因为有宾语的句子不能主谓倒装。二、 完全倒装当句中没有宾语而且主语又不

22、是代词时，假设将状语或表语置于句首，就把谓语(包括实义动词)移到主语前面。常见的有以下情况：1). 出于修辞需要，表示方向的副词：out, down, in ,up, away, on或表示地点的介词短语置于句首时。如：l Out rushed the students as soon as the bell rang.l Up went the plane.l In the north of China lies Beijing.l In the front sit some experts.2)出于习惯用法：here, there, now, then置于句首时。如：l Now is yo

23、ur turn. l There goes the bell.l Here is a ticket for you .l There existed a certain doubt among the students as to the necessity of work3)有时在主系表结构中，主语较长，为了使句子平衡，防止头重脚轻，可将表语提前，主语置于谓语后面。如：l Less important than ever is developing a meaningful philosophy of life.l Among them are some famous singers who

24、 have come to help people in need.注意：a.在完全倒装结构里主语一般为名词，如果是人称代词那么不需要倒装l “where is the cup？ “Here it is！l There he comes.l Out they rushed when the bell rang.b. 在完全倒装结构里，确定谓语的单复数要注意主语在谓语的后面。试比拟：l There come two buses at the same time.l There comes your bus.c. 全部倒装也可用于定语从句中。 He suddenly found himself s

25、tanding at the foot of a hill, on top of which stood an old temple. 三、局部倒装局部倒装即词汇倒装，就是将规定的词或短语置于句首，然后把句子谓语的一局部主要是助动词或系动词放到句子主语前，构成倒装。以下情况要局部倒装：1一些表示否认意义的副词，连词或介词词组作状语，假设置于句首，句子的主谓要局部倒装，如：never, no, neither, scarcely, little, few, seldom, rarely, not until, nowhere, at no time, on no account, in no r

29、h money to go to school.4. so+adj./adv.that 句型中，so+adj./adv置于句首时，从句倒装，主句不倒装。 Soquicklydidtheworkmencompletethetaskthattheywerepraisedbythemanager. 5.以以下副词或短语开头的句子，句子的主谓要局部倒装：often, well, always, to such a degree, to such an extent, to such a point, many a time. 6.用于前面所说的情况也适用于另一人物的肯定句或否认句中的倒装1肯定重复倒装

30、用so。 They have got up, and so has their son.2) 否认重复倒装用nor, neither。 If you dont agree to our plan, neither will they.7.在if 引导的虚拟条件从句中含有助动词had, were, 或 should 时,如将if省略,那么要将had, were, 或should等移到主语前.Should it rain tomorrow, we would put off the picnic.四形式倒装1.as引导让步状语从句，将被强调的内容状语或表语有时是动词原形置于句首。如：Much as

35、或几个成分不直接表达出来，这种现象称为省略。英语中的省略要求不破坏语法结构，要保持句子意义的准确无误。省略有词法上的省略，也有句法上的省略，还有一种替代省略。省略局部的成分和含义可从上下文或具体语言环境中找到。英语的省略大致有以下几种情况：一、简单句中的省略1. 名词所有格之后的省略。例如：lHe is going to his uncles (house). 2. 含there be结构中的省略。例如：l(Is there) Anything wrong?3. 独立主格结构中的分词如为being或having been时的省略。例如：lThe examination (being) over

36、, we all left the school. 4. 不定式的省略1有些动词，如：believe, find, think, feel, consider, imagine, prove等后作宾补的结构to be + n. / adj. 中的to be可以省略。例如：lI consider him (to be) stupid.lHis mother found him (to be) a clever boy.2感官动词see, hear, feel, watch, notice 等以及使役动词let, make, have后作宾补的动词不定式中的不定式符号to要省略，但变为被动结构时，

37、to必须保存。例如：lThey made the boy (to) go to bed early.lThe boy was made to go to bed early. 3在can not.but., can not choose.but., do nothing.but., cant help.but., prefer to do. rather than do., would do. rather than. 之后的动词不定式一般不带to；but之前有实义动词do的某个形式do, does, did, done 而且其宾语是something，nothing，anything和eve

38、rything等不定代词时，也不带to, 否那么要带to。例如： lWe have nothing to do now but wait. lI can not but admire his courage. lHe has no choice but to accept the fact. 4在并列结构中为了防止重复，后一个to省略。例如：lIm really puzzled what to think or (to) say. 【注意】但两个不定式有对照或比照的意义时，那么后一个to不能省略。例如：lI came not to scold but to praise you. 5在why,

39、 why not 引导的特殊问句中后跟省略to的动词不定式。例如： lWhy talk so much about it? lWhy not try it again?6 动词不定式在ask, warn, tell, advise, allow, permit, invite, order, would like, forbid, like, love, care，want，hope，wish，expect，prefer，refuse，decide, mean, intend, try, promise; be able to， be going to，have to,ought to，use

40、d to; happy，glad，eager, anxious，willing，ready等构成复合谓语时，不定式结构常可省略，但要保存不定式符号to。例如:lI have asked her to come，but she does not want to (come)l-Are you and Jane getting married？ -We hope to (get married)I dont want to wait for him， but l have to (wait for him)lHe doesnt like fish， but he used to (like it)

42、 teach you if you like (to)lI would do it for you, but I dont know how (to).【注意】承前省略的动词不定式如果有助动词have或be，那么要保存be或have。例如：l- Are you a doctor? - No, but I used to be .5. 同源宾语的省略同源宾语的修饰语是形容词最高级或含有最高级意义时可以省去该同源宾语。例如：lDuring the football match, the fans all shouted their loudest (shout). lShe sang her sw

43、eetest (song). 6. 英语中惯用的省略句型在What/How about后只跟名词、代词或动名词短语，以及感慨句中的省略现象。例如：lHow about the two of us taking a walk down the garden?lWhat a beautiful view (it is)!1感慨句中常省略主语和谓语，例如： lWhat a hot day ! (What a hot day it is!)lHow wonderful!(How wonderful it is!)lOh, how awful!(Oh, how awful it is!)2在日常口语中省略现象十分普遍，有时省略局部在上下文或句子本身中很容易找出。例如：lAnything else ?(Is there anything else
