状语从句+强调句
各类从句及强调句的结构和用法
各类从句及强调句的结构和用法定语从句：是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。
状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以及行为方式状语从句。
名词从句包括主语从句，宾语从句，表语从句和同位语从句及there be 句型。
一、限定性定语从句1. that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。
而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置。
2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语5. where是关系副词，用来表示地点的定语从句6. when引导定语从句表示时间注意：值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导By the time you arrive in London, we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to business trip, he brings a lot of living necessities, suchas towers, soap, toothbrush etc.7. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody,something, anything, everything或nothing时，常用there is来引导二、非限定性定语从句非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分2. 在引导限定性定语从句时，that有时相当于inwhich, at which, for which或at whichAttitudes towards daydreaming are changing in much the same way that (in which)attitudes towards night dreaming have changed.人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。

定语从句与同位语从句、强调句、状语从句的区别教学提纲
定语从句与同位语从句、强调句的区别一、定语从句1. 定语从句在句中做定语，修饰一个名词或代词，被修饰的名词、词组或代词即先行词。
定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose, that, which；关系副词有：when, where, why。
2. 限制性定语从句与非限制性定语从句（1）限制性定语从句是先行词在意义上不可缺少的定语，用于修饰和限定先行词。
如果去掉，主句的意思就不完整或失去意义。
书写时不用逗号与先行词分开。
例：This is the boy who broke the window.（2）非限制性定语从句在意义上只是一个附加修饰语，对先行词或主句作些附加的说明。
如果去掉，主句的意思仍然清楚。
书写时往往用逗号与先行词分开。
例：I, who am your friend, will share the work with you.3. 非限制性定语从句的“四个不能”：（1）非限制性定语从句通常不能用that引导。
（2）非限制性定语从句不能用why引导，要用for which 代替。
例：I had told them the reason, for which I didn’t attend the meeting.（3）由“介词+关系代词”引导时，关系代词不能用as。
（4）指人的关系代词作宾语时用whom，不能省略。
4. 在定语从句中，下列情况的关系词用that而不用which:（1）先行词被形容词最高级、序数词、数词等几种词修饰或被only, any, few, little, no, all, one of等修饰时。
例：This is the best film that I have ever read.（2）先行词为all, much, little, none, few, one, something, everything, anything等不定代词时。
高考英语强调句用法总结,必备!
高考英语强调句用法总结，必备！强调句是高中英语学习过程中常见的一种句型，也是英语学习的重点、难点。
强调句是用来表示强调说话人的意愿和情感。
它只是强调句子的某一个成分，通常强调主语、宾语或者是状语。
那么今天小编结合近几年来的高考题，对强调句的基本用法以及考点进行了全面的归纳和总结，希望对大家的学习能有所启发。
一、强调句基本句型1、强调句的陈述句句型为：It is /was+被强调的部分+that/who引导的从句+原句其他部分。
尼们可以看下面例句来体会理解：2、强调句的一般疑问句型：Is / Was +it+被强调的部分+that/ who/ whom引导的从句+原句其他的部分。
3、强调句的特殊疑问句型：特殊疑问词（When /Where/ Why/ Who/ What/ How ）+is/ was +it +that从句+原句的其他部分。
二、需要注意的问题1、无论强调据说强调的主语是单数还是复数，强调句中所用的be动词始终都是is或者是was，如果强调的是将来或者是正在发生的事情或正在进行的动作的时候，只能用is；如果强调过去已经完成的就用was。
2、大家需要记住一点，强调句去掉了it is/ was…+that之后，对于句子的完整性不造成影响，这也是与其他句子区分有一个重要标志。
三、考点归纳1、主谓一致。
在强调主语的时候，that后的谓语动词要与被强调者保持是人称和数的一致，例如：It is I who am a teacher.2、连接词。
在强调状语的时候，无论被强调的部分是表示时间还是地点, 能不能用when或者where，连接词只能用that。
同时要注意与下列句型的区分：3、考查对“not…until…”进行强调，常会使用句型“It is / was… not …until…that…”这个强调句型是高考的高频考点，意思是“不是……而是……”。
4、考查与主语从句，状语从句和定语从句的辨析强调句很容易和名词从句这个句型混淆，如：It is clear (obvious, true, possible, certain…) that…大家要清楚这里的it是形式主语，真正的主语是that引导的主语从句。
强调句型
强调句强调句结构为：It is(was) ＋被强调部分＋that(who)＋其他成分，此结构强调的成分仅限于主语，宾语和状语，不能是定语或谓语，强调人时可用who 或that作连词，强调其他成分用that。
1．强调的成分(1)强调主语：句子的谓语动词和被强调的主语保持一致。
It was he who(that) read three books in the library yesterday.是他昨天在图书馆里读了三本书。
It is they that were late.他们迟到了。
It is I who (that) am to blame. 是我应该受责备。
(2)强调宾语It was a Canadian that/whom Mary met in the park last Sunday.玛丽上周日在公园里遇到的是一位加拿大人。
(3)强调状语：状语既可以是短语也可以是状语从句①强调时间，地点或方式状语时，要用that，不能用when，where 或how等。
It was in the library that he read three books yesterday.昨天他是在图书馆里读的三本书。
It was last Sunday that Marry met a Canadian in the park.玛丽是上周日在公园里遇到了一位加拿大人。
②强调原因状语从句，从句只能用because 引导，不能由since，as或why引导。
It was because he was ill that he couldn’t come to school.正是因为他病了，他才没来上学。
③对not... until... 句型的强调结构为It is not until...that...，that后面从句用肯定形式。
It was not until the rain stopped that I went home.直到雨停了我才回家。
辨别强调句、定语从句、主语从句、状语从句
辨别强调句、定语从句、主语从句、状语从句（要点精讲）一、强调句与各从句的比较1．强调句与主语从句的比较强调句将句子中的It is/was … that同时省去，句子仍然成立；而主语从句不能。
如：(1)It was Tom that saw Jane at the movie theater yesterday. 是汤姆昨天在电影院见到简。
本句若将It was及that同时省去为：Tom saw Jane at the movie theater yesterday. 句子同样成立，因此该句是强调句。
(2)It is true that he is a man of few words.本句若将It is及that同时省去为：true he is a man of few words.，显然句子错误，因此，该句不是强调句，而是主语从句。
2．强调句与定语从句的比较(1)强调句中的It没有实际意义，It be与that同时去掉后句子仍然成立；而定语从句中的It be与that不可同时省略。
(2)在强调句中连接词只有that、who，并且不可以省略；而在定语从句中一般使用关系代词that，which，who，whom或关系副词when，where，why等，而that在从句中作宾语的时候可以省略。
(3)强调句中可以用副词、介词短语或从句来作被强调的内容；而定语从句的先行词（中心词）一般是名词或名词短语。
比较下列句子①It is on the island that they spent 10 years.②It is the island where (on which) they spent 10 years.解析：①表示地点的名词the island前有介词与其连用，说明它是一个完整的地点状语。
如果将it is及that去掉：They spent 10 years on the island.它的意义仍然完整。
英语中常见的强调句型
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: 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。
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 collge entrance exam. ⾼考并不是每个⼈都能上线。
强调句与从句的比较
强调句与从句的比较1. 强调句与定语从句的比较【1】强调句中的It没有实际意义，it is/ was …that可被省略；而定语从句中的It可以作主语或宾语等成份，It be与that不可同时省略；【2】强调句将句子中的that不能省略，也不能换成which；而that引起定语从句，that作宾语时可被省略，并且当先行词是事物时可用which代替。
【3】运用定语从句时，先行词如果是时间、地点名词，定语从句引导词引导词可用that/ which 或者when/ where。
如：比较：(1)A: It was a film (that) I saw at home with my father last night.(本句是对What is that问句的回答，来说明“昨晚我和父亲在家看的什么”that所引导的是定语从句，that可被省略)B: It was the film (that) I saw at home with my father last night.昨晚我和父亲看的就是这部电影。
(本句相当于对I saw the film at home with my father last night中a film进行强调)(2)A: It was the room where we used to live.它是我们过去住过的房子。
(where 所引导的从句对前面的room进行说明，它是定语从句) B：It was in the room that we used to live.过去我们就是住在这间房子里。
(in the room是被强调的部分，本句是强调句型)判断：It is a day when the people celebrate their victory.这是人们庆祝他们的胜利的日子。
(when所引导的从句对a day进行说明，是定语从句)It was on the day that people celebrated their victory.就在那一天，人们庆祝了他们的胜利。
