【解析】【分析】句意：—我确实相信两个小时内能完成考试。这里用来强调，在谓语动词前加助动词do表示强调。句子的主语是第一人称，所以位于动词不能用单数，故排除A；did后用动词原形；do后用动词原形，故选B。
【点评】本题考查强调句型。以及does believe；do believe；did believed；do believed四种强调句子的区别和用法。
3．Mike likes playing basketball.

【答案】 D
【解析】【分析】句意：迈克喜欢打篮球。他的确如此。本句是表达“……的确如此”，用半倒装句“so+主语+be/助动词/情态动词”，上句是实义动词，且为一般现在时，主语是he，第三人称单数，因此助动词用does，即So he does，故选D。

A. to fighting, where
B. of fighting, that
C. of fighting, where
D. to fighting, that
【答案】D
【解析】【分析】考查非谓语动词和强调句式。approach to doing sth.做某事的方法。句意：这位70岁的老人在南方打击犯罪的铁拳方法使其确立了自己的政治名声。此句是强调
句式，所以第二空填that，故选D。
【点评】强调句型。1.在英语中，我们常用It is/was… who/that结构来突出强调句子的某一
成分（一般是句子中主语，宾语或状语）。在这个句型中，it没有词汇意义，只是引出被
强调的成分。如果被强调的成分是表示人的词，用who或that来连接都可以。如果是其它
成分，则一律用that来连接。It is my mother who/that cooks every day.是我的妈妈每天做饭；It was yesterday that Tom passed in the maths exam.是昨天汤姆通过了数学考试。2.被强
调成分是主语，who/that之后的谓语动词应该在人称和数上与原句中的主语保持一致。It is
I who am right.It is he who is wrong. It is the students who are lovely.3.被强调部分既包括人又
包括物，用that不用who。lt was the things and people that they remembered that they were talking about.

A. what; that
B. which; that
C. where; that
D. where; where
【答案】 C
【解析】【分析】句意：就是在我母亲工作的那个小农场里，我度过了我的整个童年。第
一个空是定语从句中的先行词，the little farm 被一个定语从句修饰，the litte farm是先行
词，在从句中作状语，如放在从句中应该是 my mother used to work in the farm。因此，要
用in which或where。第二个空是一个强调句型，强调句型It is +被强调部分+that+剩余。

小农场度过我的整个童年。故选C。

S+V+O+OC （主语+及物动词+宾语+宾语补足语）He made (及物) the boy laugh.说明：（S＝主，V＝谓，O＝宾，P＝表，IO＝间宾，DO＝直宾，OC＝宾补） . 一、第1种句型：S+V（主语+不及物动词） 1、Birds fly. 鸟飞。 主语＋谓语(不及物动词) 2、He runs in the park. 他在公园里跑。 主语＋谓语＋地点状语(不及物动词) 此句型是“主语+不及物动词”构成句子的主体部分。因为是不及物动词，后面当然不能带宾语了，但是可以有状语来修饰。例如上面例句中的in the park就是地点状语。 3、Class begins.（begin在句中是不及物动词）上课了。 比较：We begin our class at eight. 我们八点钟开始上课。 该句则属于第2种句型，begin在句中是及物动词，由此可见有些动词既可作及物动词也可以作不及物动词。 # 只能当不及物动词的词（必背！）： sleep睡觉walk步行swim 游泳happen（take place）发生 go去come 来work工作laugh笑 stay呆在……arrive到达

强调句型的结构及其用法 强调句是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式，下面简单归纳它的几种结构： 一、强调句型的基本结构 1．用助动词“do（does／did）＋动词原形”来表示强调： He does know the place well．他的确很熟悉这个地方。 Do write to me when you get there．你到那儿后务必给我来信。 2．用形容词very，only，single，such等修饰名词或形容词来加强语气：That’s the very textbook we used last term．这正是我们上学期用过的教材。ou are the only person here who can speak Chinese．你是这里唯一会讲汉语的人。 Not a single person has been in the shop this morni ng．今天上午这个商店里连一个人都没有。 How dare you buy such expensive jewels？你怎么敢买这么贵的宝石呢？3．用ever，never，very，just等副词和badly，highly，really等带有－l y 的副词来进行强调： Why ever did you do so？你究竟为什么要这么做？ He never said a word the whole day．一整天，他一句话也没说。 You’ve got to be very，very careful．你一定得非常、非常小心。 This is just what I wanted．这正是我所要的。 He was badly wounded．他伤得很严重。 I really don't know what to do next．我的确不知道下一步该怎么做。4．用in the world，on earth，at all等介词短语可以表达更强的语气（常用于疑问句）： Where in the world could he be？他到底会在哪儿？ What on earth is it？它究竟是什么？ Do you know at all？你到底知不知道？ 5．用感叹句来表示强烈的感情，突出说话人的情感： How interesting a story it is！这是一个多么有趣的故事啊！ Oh，what a lie！啊，真是弥天大谎！ 6．用重复来表示强调： Why！why！The cage is empty！啊！啊！箱子是空的。 They walked for miles and miles．他们走了好多英里。 7．用倒装句（也就是将要强调的句子或被强调的部分置于句首）来加强语气：On the table were some flowers．桌上摆着一些花。（强调地点） Many a time have I climbed that hill．我多次翻过那座山。 Only in this way，can we solve this problem．只有这样，我们才能解决这个问题。 8．用强调句型：“It is（was）＋被强调的部分＋that（who）＋原句其它部分”来强调说话人的意愿： It was on Monday night that all this happened．所有这一切发生在周一晚上。
It is to let the fresh air in that I often keep the windows wide open. … 第二节：应该注意的问题 用It's…that/who结构对句子进行强调时应该注意一下几个问题： 1.这种结构只有一般现在时和一般过去时两种时态。其他的时态很少用这种句式进行强调。 It has been four years _____ I gave up smoking. A.that. B. since. 分析：遇到这种高考题，我们就毫不考虑的选B. since. 2. 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. 3. 即使被强调的主语是复数，主句中的谓语动词也用单数。换句话说：强调句中不可能出现am, are, were。如： It is they who often help me with my lessons. 4.强调句和it作形式主语的区别。 强调句中的It's, that/who在句中只是一种语法手段，没有任何意义，如果去掉不会对句子的意思产生影响，或不会影响句子的完整性。但是，it作形式主语的结构如果去掉句子就不完整。因为that引导主语从句时不能省略，而且is/was在句子中充当谓语（系动词）。 It is a good idea that we eat out. 分析：如果去掉it is 和that, We eat out said. 很明显时个不完整的句子。 5.强调时间状语的强调句和时间状语从句的区别。 时间状语从句中主句和从句都是完整的句子，it指代时间，如果把其中的it, is/was和when去掉，句子将不完整；而强调句则完整。 It was 12:00 we went home. A. that B. when. 分析：如果去掉it was和横线，We went home 12:00。很明显这是个错误的句子，缺少介词at. 真确的句子因该是： We went home at 12：00. 6.强调句和as引导的定语从句的区别。 这两种句型的区别比较简单，在定语从句一章有详细讲解，此处不再赘述。 总之，区别强调句和其他句式最有效的方法是：去掉it, is/was, that/who或横线后看句子是否完整。如果完整肯定是强调句，不然为其他句式。 7.强调句的反义问句。 强调句的反义问句比较简单，只要将它看成it is/was…的句子就可以了。 It is…that…, isn't it? It is not…that…, is it? It was…that…, wasn't it? It was not …that…, was it? 第三节：高考常见题型 1.强调句的一般形式。
龙文教育学科教师辅导讲义（10.23） 教师：_王琴_ __学生：__ __ __时间:_2011____年____月____日____段 It 引导的句型 一、It作形式主语的句型 为使句子平衡，往往把it置于句首作形式主语，而把真正的主语（通常是不定式短语、动名词短语或主语 从句）移至句末。It 作形式主语的句型有： 一、㈠it 代指不定式短语的句型 1.

It is + 形容词+ (for / of sb.) to do sth. 某人做某事是… …的 常用于该句型的形容词比较多。for sb. 的句型常用于表示事物的特征特点，表示客观形式的形容词，如easy, difficult, hard, important, possible, impossible, comfortable, necessary, better等。of sb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如kind, nice, stupid, rude, clever, foolish, thoughtful, thoughtless, brave, considerate(考虑周到的), silly, selfish(自私的) 等。 It was not right for the south to break away from the union. 南方脱离联邦是不对的。 It was kind of you to help us. 谢谢你对我们的帮助。 It is getting harder every day for a lazy man to get a living. 懒汉谋生是越来越困难了。 What time would it be most convenient for me to call again? 什么时候我再给你打电话最合适？ It’s very good of you to have listened to me. 感谢你能听我讲。 It’s very thoughtful and kind of you to offer me this lovely holiday. 你能给我这么美好的假日，实在是想得太周到、太友善了。 4. It is + 名词+ to do sth. 做某事是… …的 常用于该句型的名词有：manners, duty, fun, good, a great honour, the first, the next, the last, the best, too much, too little, not enough等。 As a student, it is bad manners to come late to class.

We should learn from them. A. they B. them C. their D. theirs 【答案】 A 【解析】【分析】根据题干，这是一个强调句，强调主语！英语中为了表达的正式，这时应用主格的代词。本句的意思是“就是他帮我们脱离的危险。”所以本题选A。 【点评】对于强调句中强调主语时应注意，如果不加分析可能会选择them。这在平时的学习中一定要注意分析。 3．It's his brother ________ never been to Australia. You'd better take him with you. A. that is B. who is C. that have D. who has 【答案】 D 【解析】【分析】句意：是他的弟弟从没去过澳大利亚，你最好带他跟你去。have been to 去过……。强调句型是：It is+被强调部分+that（指人时用who）+句子的其他成分。此处强调句子的主语his brother，故谓语用has。因此选D。 【点评】考查强调句型。 4．I _____ you can finish the exam in two hours. A. does believe B. do believe C. did believed D. do believed 【答案】 B 【解析】【分析】句意：—我确实相信两个小时内能完成考试。这里用来强调，在谓语动词前加助动词do表示强调。句子的主语是第一人称，所以位于动词不能用单数，故排除A；did后用动词原形；do后用动词原形，故选B。 【点评】本题考查强调句型。以及does believe；do believe；did believed；do believed四种强调句子的区别和用法。
记住六个句子，掌握强调句型 句子 1ItwasalongtheMississippiRiverthatMarkTwainspentmuchofhisch ildhood. 在密西西比河沿岸，马克·吐温度过了他大部分的童年时光。 【知识点】强调句型的基本结构是：Itis/was+被强调部分+that+其余部分。如果被强调部分是人，也可以用who代替that。如：Itwashisteacherwhoheoftenreferredtowhenintrouble. 他在困境中经常提到的那个人是他的老师。 注意：1.句首词用it，不能用this/that等。 2.be动词总用单数形式，即is或was，不能用复数形式are或were。 3.把itis/was和that去掉，如果剩余部分的句子结构仍然完整
（被强调部分要还原到原位置），那幺这个句子就是强调句；如果句子结构不完整，则不是强调句。如： （1）ItwasatthetheatrethatLincolnwasmurdered. （2）ItwasthetheatrethatLincolnwasmurdered. 把两个句子中的itwas和that去掉，我们可以看出，句（1）仍是一个完整的句子，是强调句；句（2）不完整，不是强调句。 句子2Itwasnotuntilmidnightthattheyreachedthecampsite. 直到午夜他们才到达野营地。 【知识点】若强调“notuntil...”句型中的“until...”部分，要将“notuntil...”放在itis/was与that之间。如： ItwasnotuntilIcameherethatIrealizedthisplacewasfamous，fornotonlyitsbeautybutalsoitsweather. 直到我来到这里，我才意识到这个地方出名，不仅因为它的美，而且因为它的天气。 注意：此句型只用until，不用till（如果不是强调句型，till
it 做形式主语引导的主语从句和作强调句型的区别
但若被强调部分是状语时，则只能用that ，即使指时间、地点、原因等，也不能用when ，where 或because 等替代。 如：It was my sister whom I met in the street yesterday. It was only when I reread his poems recently that I began to appreciate their beauty. It was for this reason that her uncle moved out of New York and settled down in a small village. 4 . 注意该句型一般不强调谓语动词强调句型通常强调主语、宾语和状语，一般不强调谓语。需强调谓语时，要在谓语动词原形前面加上助动词do ，does 或did ，尤其是在祈使句或肯定句中，用来加强语气。 如：Do tell me where on earth you are now! Boys and girls , let me tell you something that does sound strange. To my surprise, he did come here on time last night. 5 . 注意区分含有Not until 的倒装结构和强调结构Not until 用于句首时，主语和谓语通常用倒装语序。如果是复合句，那么主句用倒装语序。但在“ It is / was not until …. that ”句型中，that 后的主谓不倒装。 如：It was not until she took off her dark glasses that I realized she was a famous film star. 本句是由I didn't realize she was a famous film star until she took off her dark glasses 变化而来的。命题者有意将状语从句until she took off her dark glasses 置于It was … that 这个强调句型中，考查考生的判断能力。此句还可用倒装结构来表达。 如：Not until she took off her dark glasses did I realize she was a famous film star. 6 . 注意强调句型与主语从句“ It is /was… that… ”的区别主语从句中It is / was 后通常有名词或形容词作表语，而强调句型中It is/ was 后是对主语、宾
五种基本句型——主系表结构 主（语）＋系（动词）＋表（语） 主语，主语是五种基本句型都具备的。 从位置上来看，主语一般在句子开头，也就是一个句子的“头把交椅”。 从意义上理解，主语一般是一个句子的“陈述对象”，后面的一切都是针对主语来说的。主语一般是名词或代词（当然还有其他，这里暂且详细讨论） 系动词是联系动词的简称，顾名思义，它是起到联系作用的动词，是连接主语和表语的。系动词的数量是有限的，常见的只有十来个，我们把它们分成四组，这样有助于我们记忆系动词： 一、 be动词类： am、 is 、are 、was 、were 二、表示变化类：become、 get 、 turn 、 grow 、go 三、感官动词类: 眼（look ）耳(sound)鼻(smell)舌(taste)身(feel) 四、表示延续性的动词：remain 、stay 、keep 表语 从位置上来讲，它总是在系动词后面（系动词和表语关系甚为紧密，没有系动词，就没有表语：没有表语，就没有系动词。 二从意义上讲，表语通常是来说明主语的性质、特征的。表语通常是由形容词、介词短语、名词、代词、动词不定式、doing 等来充当。
上面就是对主系表结构的简要介绍，其中，系动词是主系表结构的核心，它是这个结构的标志，看到了系动词，也就能立刻判断出句子的结构是主系表，因此，记住系动词非常重要。 练习 找出下面句子中的主语、系动词及表语，并指出主语和表语分别是由什么词性或词类来充当的。 1 Tom is a student. 2 He is fat. 3 I am tired . 4 We are students. 5 The bag was lost . 6 The boy was foolish . 7 They were kind. 8 She is in the room. 9 The books are on the desk. 10 Snow is white. 11 Kate was here yesterday.
强调句型完整归纳 一、初中英语强调句 1．______ he will return to his native land. A. It is long before that B. It will be long before that C. It won't be long before D. It is before long that 【答案】 D 【解析】【分析】句意：不就以后他就会回到他的祖国了。本题强调的是时间状语before long不久以后；强调句型的基本结构为It is/was被强调成分that/who其它成分；其最大的特点就是去掉it is/was…that/who…句子仍然成立。要注意强调句型能强调除谓语动词以为的所有的句子成分。在考查的时候，经常会把强调句型和定语从句结合在一起考查，要注意分析句子的成分。故D正确。 【点评】考查强调句型，掌握其结构：it is/was…that/who…。 2．It's his brother ________ never been to Australia. You'd better take him with you. A. that is B. who is C. that have D. who has 【答案】 D 【解析】【分析】句意：是他的弟弟从没去过澳大利亚，你最好带他跟你去。have been to 去过……。强调句型是：It is+被强调部分+that（指人时用who）+句子的其他成分。此处强调句子的主语his brother，故谓语用has。因此选D。 【点评】考查强调句型。 3．Mike likes playing basketball. A. so does he. B. So he is. C. So she does. D. So he does. 【答案】 D 【解析】【分析】句意：迈克喜欢打篮球。他的确如此。本句是表达“……的确如此”，用半倒装句“so+主语+be/助动词/情态动词”，上句是实义动词，且为一般现在时，主语是he，第三人称单数，因此助动词用does，即So he does，故选D。 【点评】考查副词so位于句首的倒装形式。注意当主语是人称代词时，要用半倒装形式。 4．—Who was calling you on the phone just now? — _______. A. That's him B. It was Tom C. This was someone D. Maybe Jim's 【答案】 B 【解析】【分析】句意：——刚才谁在电话里叫你？——他是Tom。根据题意可知，答句为强调句，完整形式为It was Tom that call you on the phone just now. 缩写形式为It was
1、It is＋被强调部分＋that …该句型是强调句型。将被强调的部分放在前面，其它部分置于that 之后。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 可以由who 换用。如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 It was about 600 years ago that the first clock with a face and an hour hand was made. It was they that（who）cleaned the classroom yesterday. It was in the street that I met her father. 2、It is important（necessary, right, strange, natural…）that …该句型和上一个同属一种句型。由于主句中的形容词不同，that 后的从句中要用虚拟语气（should＋动词原形），should 可以省去。建议记住该句型中的形容词。 It is important that we（should）learn English well. It is necessary that he（should）remember these words. 3、It is said（reported, learned…）that …该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为“ 据说（据报道，据悉……）”。 It is said that he has come to Beijing. It is reported that another man-made satellite has been put into orbit. 4. It is suggested（ordered, required …）that …该句型和上一个同属一种句型。主句中的过去分词是表示请求，建议，命令等词时，that 后的从句要用虚拟语气（should＋动词原形），should 可以省。常译为“ 据建议；有命令……”。 It is suggested that the meeting（should）be put off. It was ordered that we（should）arrive there in two hours. 5、It is a pity（a shame …）that …该句型中，that 后的从句一般用虚拟语气（should＋动词原形），should 可省去. 表示出乎意料，常译为“竟然”。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing（should）happen in your class. It is a pity that he is ill. 6. It is the first（second …）time that …该句型要和上一个句型区别开来。该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it 有时用this 替换，常译为“是第一（二）……次……”。 It is the first time I have been here. ＝This is the first time I have been here. 7.It is … since … 该句型主要用作处理瞬间动词的完成时，又要和表示一段时间的时间状语连用的问题。主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。 It is（has been）5 years since his father died. 8. It be … before …该句型主句中的it 指时间, 主句中的时态常是将来一般时或过去时两种时态. 主句中的表语多是long, not long , 3 days , 2 weeks 等表示时间段的词或短语。常译为“……之后……”。 It was 3 days before he went to Beijing. It will be not long before he finishes his job. 13. It happens（seems, looks, appears）that…该句型中it是形式主语，that 引导的是主语从句，主句的happen, seem 等词是不及物动词。 It happened（so happened）that he met his teacher in the street. 碰巧…… It seems that he will be back in a few days. 看来……
