英语中的强调句型句型
英语中的强调句型 王珂 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 ) clea ned the classroom yesterday. It was in the street that I met her father. 2.

英语中英语强调句的几种强调方式
英语中英语强调句的几种强调方式 我们在说话或写文章时，为了要突出句子中的某一部分，我们通常会使用某种方法或手段使它突出，以便能引起他人的注意，这就是强调，与此相关的句子就是强调句。英语表示强调的方法很多，比如在口语中可以用重读来强调，在书面语中则可通过使用表示强调意义的词语来强调，也可以通过将被强调成分置于句首这样的“显要”位置来强调，还可以使用专门的强调句式来强调。 一、用助动词do来强调 当句子中没有其他的助动词时，我们可以在动词前使用助动词do 表示对该动词的强调。如： Do be careful with that vase! 务必小心那个花瓶!
I do hope you'll stay for lunch. 我真的希望你留下吃午饭。 用于表示强调的do可以有时态的变化，但其后的动词要用原形。如： He does look tired. 他确实显得很疲倦。 He did come but soon went back. 他的确来过，但很快就回去了。 She did write to say thank you. 她的确写信向你道谢了。 注意，这样用的do只用于现在时或过去式(即只有do, does, did 这样的形式)，不能用于进行时、完成时等形式(如不用于is doing, has done等)。
二、用某些形容词来强调 英语中用于强调的形容词比较多，比如那些表示“极端”和“完全”概念的形容词通常就可以用于表示强调，这类形容词主要的有： mere 仅仅的very 极端的 outright 完全的thorough 十足的 plain 完全的complete 彻底的 pure 完全的perfect 全然的 Jim looked a perfect fool. 吉姆看起来像一个十足的傻瓜。

英语强调句型
强调句型 构成：It is/was +被强调部分+ that +其他成分。如果被强调的部分是人，可用who代替that。该句型可对主语、宾语、表语、状语（除谓语以外的其他成分）进行强调。 I met my old friend in the street yesterday.昨天我在街上遇到了我的老朋友。 It was I who/that met my old friend in the street yesterday.(强调主语) It was my old friend who/that I met in the street yesterday.(强调宾语) It was in the street that I met my old friend yesterday.(强调地点状语) It was yesterday that I met my old friend in the street.(强调时间) 使用强调句型时须注意以下几点： (1)强调句型中的it不能用其他词代替；用is还是 was要根据原句的时态而定。属于现在或将来时间范畴的所有时态用is; 属于过去时间范畴的所有时态用was。 (2)被强调部分可以是除谓语动词以外的其他成分， 当被强调部分指人时，可以用who代替that，其

强调句 一、强调句的基本结构及用法 强调句常用来突出说话人要强调的语言信息，给对方以强烈的印象和感受。译成汉语 时，常加上“正是”等字眼。其基本结构是：It + be的适当形式+ 被强调成分+ that (who) + 其他成分He bought the book in this shop yesterday. →It was he that bought the book in this shop yesterday. (强调主语he) →It was the book that he bought in this shop yesterday. (强调宾语the book) →It was in this shop that he bought the book yesterday. (强调地点状语in this shop) 【注意】 1.在该强调结构中，It无任何意义但不可以换成this或者that等。 It is (was)…that (who)…为结构词，假如去掉，剩下部分在语法结构和句子含义上均完整，这一点正是它和定语从句等的本质区别。 2.关于that与who 当被强调部分指人时，可以用who（被强调部分的人作主语或宾语时）或者whom（被强调部分的人作宾语时)代替that； 当被强调部分指物时通常用that；当被强调部分既包括人又包括物，用that不用who. It was the things and people that they remembered that they were talking abo ut． 当被强调部分是代词时，用who不用that。 当强调时间或地点或原因状语时，不能用when / where /why代替that(尤其是当这些状语为介词短语时)。1）It was only when I reread his poems recently I began to appreciate their beauty. A. until B. that C. when D. so 2）It was in Qingdao I saw the sea for the first time. A. what B. that C. when D. which 3）It was because of bad weather the football match had to be put off. A. so B. so that C. why D. that 如果被强调的成分有同位语，同位语也应提前。 It was from him, his chemistry teacher, that Paul learned to watch carefully in class. 3.关于be的适当形式： 在强调结构中，无论被强调的是人还是物，单数还是复数，be动词一律用单数is/was形式。 ①如果原句的谓语动词时态是现在范畴(一般现在时、现在进行时、现在完成时、现在完成进行时、一 般将来时、将来进行时、将来完成时等)，就用is。 It is the ability to do the job matters not where you come from or what you are. A. one B. that C. what D. it ②如果原句的谓语动词时态是过去范畴(一般过去时、过去进行时、过去完成时、过去将来时等)，就用was。例如: It was between 1989 and 1999 great changes took place in our hometown. A. when B. that C. which D. because ③也可以根据需要用It may/might/must be that/who; It must have been that/who 如: It might be Sally that you are thinking of. It might be in the morning that he broke into the house. It might be his father that you are looking for. It must be John that/who will take part in the contest on behalf our class.

英语强调句型详解及练习
1. 强调结构的陈述式 强调结构的陈述式为“It is （was）+ 被强调部分+ that （who）…”。该结构可用于强调主语、宾语、状语等，但不能强调谓语动词。该句式中用that或who的区别是：当被强调的指人时，用that或who均可；当被强调的不是指人时，则只能用that（注意不用which）。如：It was in the office that he was killed. 他是办公室被杀害的。（强调in the office） It is the children who broke the window. 是孩子们打破窗户的。（强调the children） It was to you and not anyone else that I lent the money. 我只借钱给你，不借给其他人。（强调to you and not anyone） It is only when you have your own children that you realize the troubles of parenthood. 当你有了自己的孩子，才能真切地了解到双亲的辛苦。（强调only when you have your own children） 2. 一般疑问句的强调结构 一般疑问句的强调结构就是将be提到句首，即使用“Is / Was it+ 被强调部分+ that / who…”。如：Is it Tommy who answered the telephone? 是汤米接的电话吗? Is it from advertising that a newspaper earns a lot of its profits? 报纸获利最多的部分是在于广告收入吗？ 3. 特殊疑问句的强调结构 特殊疑问句的强调结构句型为“疑问词（Who / What / When / Where / Why / How）+is / was it that…”这样的形式。如：When was it that he got married? 他是什么时候结婚的? How long ago is it that you last saw her? 你上一次看见她是多久以前的事? Who was it that won the World Cup in 1982? 谁赢得了1982年的世界杯? Why is it that I always land up cleaning the bath? 为什么总是该我来洗刷浴缸? In which play of Shakespeare's is it that Viola appears? 维欧拉是在莎士比亚那个剧里出现的吗? 强调句的结构是“It is / was +强调部分+ that / who-从句”，it在句中作先行词，被强调 的部分通常是主语、宾语和状语。这是it的主要用法和考点之一。 It is the ability to do the job ____ matters not where you come from or what you are. A. one B. that C. what D. it 答案是B，其中that。又如： It was December26, 1893 ____ Mao Zedong was born in the common village. A. when B. that C. which D. in which 答案分别是D和A。前一句是强调句，因为被强调的部分in 1969是that从句中一个完整的句子成分，改为非强调句后的句子是：The American astronaut succeeded in landing on the moon in 1969。而后一句的December 26, 1893不能成为从句的一个完整成分，所以不是强调句，而是定语从句，December 26, 1893是先行词。在强调句中，it是先行词；在第二句中，it作主语，指时间。 六．被强调的不管是单数还是复数名词，主句的be动词都用单数，即is或was。例如： It ____ Madame Curie and his husband Pierre who discovered radium. A. is B. was C. are D. were 答案是B。由于所叙述的是过去的事，不能用is。 (1) Who was it _____ saved the drowning girl? A. since B. as C. that D. he 答案选C，被强调成分为who，该句实为类似It was Tom that saved the drowning girl. 这类强调句的特殊疑问句形式（即对其中的Tom 提问而得）。 (2) What is it _____ his daughter needs most? A. what B. which C. that D. if 答案选C，被强调成分为what，该句实为类似It is a bike that his daughter needs most. 这类强调句的特殊疑问句形式（即对其中的a bike 提问而得）。 5. It was what he meant rather than what he said ______ annoyed me.
英语倍数表达法基本句型

谈谈中学英语中的强调句型
谈谈中学英语中的强调句型 在中学英语教学中，提到强调句型时，通常指的是："It be…that…"这一结构（简称It-type 强调句）。这确实是一个非常有用的句型，在中学英语课本中也多次出现，例如：It is not only blind men who make such stupid mistakes.(SBI,P28) 决不只是盲人才犯这样愚蠢的错误。 It was the goat's eyes that he had seen in the darkness.(SBI,P211) 他在黑暗中看到的就是这只山羊的眼睛。 It-type强调句的特征是：如果我们把"It be…that…"从句中划去，所剩的正好是一个完整的句子。例如上面第一句经过处理后就成了： Not onlt blind men make such stupid mistakes. 它的意思仍然是完整的，只是强调意味已经失去。实际上"It be…that…"只不过是一个框架而已，它的各部份在句子中均不担任成份。 It-type强调句通常可用来强调句子的主语、宾语、状语。但强调状语时，有几个方面是必须注意的： 1.条件，让步状语从句不能强调，例如： If it rains,we won't go out. 如果下雨，我们就不出去。 We'll try to finish the work in time though we are short ofman power. 虽然我们缺乏人力，我们还是要设法按时完成这项工作。 不能强调为： It is if it rains that we won't go out. It is though we are short of manpower that we'll try to finish the work in time. 2.It-type强调句可强调because引导的原因状语从句，但不可强调as,since引导的原因状语从句，例如： I do it because I like it.因为我喜欢，我才干。 可强调为： It is because I like it that I do it. 下面这个句子则不可以强调： Since no one is against it,we'll adopt the proposal. 既然没有人反对，这个议案我们就通过了。 3.It-type强调句可强调so that引起的目的状语从句，但不能强调so that引起的结果状语从句，例如： The six blind men asked the driver to stop the beast so that they could have a "look". 六个盲人要求赶象人让这头巨兽停下来，以便他们能“看一看”。 可强调为： It was so that they could have a "look"that the six blindmen asked the driver to stop the be ast. 下面这个句子则不可以强调： He didn't plan his time well,so that he didn't finish thework in time. 他没有把时间计划好，结果没有按时完成这项工作。 4.对由until引起的短语或从句强调，要注意否定前移，例如： I didn't learn it until yesterday. 直到昨天我才知道这件事。
英语中常见的强调句型
英语中常见的强调句型 英语中有时为了需要，经常要强调句子中的某一成分，要用到一些强调句型。英语中常见的用来表示强调的句型有以下几种。 1. It is / was + 被强调部分 + that + 其他成分(其中被强调部分主语?宾语?状语，但不能是定语或谓语) 如: I met him in the park this morning. It was I who / that met him in the park this morning.(强调主语) 今天早上正是我在公园里遇见了他。 It was him that I met in the park this morning.(强调宾语) 今天早上我在公园里遇见的正是他。 It was in the park that I met him this morning.(强调地点状语) 今天早上我正是在公园里遇见了他。 It was this morning that I met him in the park.(强调时间状语) 正是在今天早上我在公园里遇见了他。 再如：He didn’t go to school today because he was ill. It was because he was ill that he didn’t go to school today.(强调原因状语) 今天他没去上学是因为他生病了。 注意 (1)如果原句中谓语动词使用的是现在范畴的时态(一般现在时?现在进行时?现在完成 / 现在完成进行时?一般将来时?将来进行时?将来完成时等)用It is...that...。如果原句中谓语动词为过去范畴的时态(一般过去时?过去进行时?过去完成时?过去将来时等)则用It was...that...。如: It was Peter who / that got the first place in the final exam. 正是彼特在期末考试中得了第一名。 It is not everyone who / that can pass the college entrance exam. 高考并不是每个人都能上线。 (2)强调句型的一般疑问句只需把is / was提前，它的特殊疑问句只需在一般疑问句前加上疑问词。如: Was it Smith who / that broke the window? 是史密斯打碎窗子的吗? Who was it that broke the window? 是谁打碎了窗子? (3)not...until...的强调句式:当被强调的是not...until...句型时，应将not置于until之前，主句由否定句改为肯定句。如: We didn’t recognize her until she took off her glasses. 她把眼镜拿了，我们才认出她。 It was not until she took off her glasses that we recognized her.

A. that B. which C. how D. where 【答案】 A 【解析】【分析】句意：就在我回家的时候，我才意识到帮助处于困境中的人是一种多么美好的感觉。强调句型的基本结构是：It is/was+被强调成分+that/who+其他成分；本句强调的是时间状语从句when we were returning home，所以选A。 【点评】考查强调句型，掌握其结构It is/was+被强调成分+that/who+其他成分。 2．It's a long time ago ______ I saw you last time.
