定语从句与强调句
定语从句与强调句型
定语从句与强调句型在英语语法中，定语从句（adjective clause）和强调句型（emphatic construction）是两个重要的语法结构。
它们能够丰富句子的表达方式，并帮助我们更准确地描述事物或进行强调。
本文将介绍定语从句和强调句型的定义、用法和例句，并探讨它们在英语写作中的应用。
一、定语从句定语从句是一个修饰名词或代词的句子，用来对该名词或代词做进一步的描述。
定语从句通常用于限定、说明、或者描述名词，在句中充当定语的角色。
在定语从句中，通常使用关系代词（如who, whom, whose, which）或关系副词（如where, when, why）引导。
定语从句的引导词根据其作用分为三类：1. 人关系代词：who, whom, whose, that2. 物关系代词：which, whose, that3. 地点关系副词：where时间关系副词：when原因关系副词：why下面是一些使用定语从句的例句：1. I have a friend who is a doctor. (定语从句修饰friend)2. The book that I bought is very interesting. (定语从句修饰book)3. This is the house where I was born. (定语从句修饰house)二、强调句型强调句型是用来强调句子中的某个成分，使其在句子中显得更加突出。
强调句型通常使用强调副词（如only, just, even, still, merely）或强调代词（such as myself, himself, herself, themselves）来引导，并将要强调的成分放在句子的开头或结尾。
下面是一些使用强调句型的例句：1. It was John who won the competition. (强调主语John)2. I bought this dress for myself. (强调宾语myself)3. She is such a kind person. (强调形容词kind)三、定语从句和强调句型在写作中的应用定语从句和强调句型在英语写作中具有很高的灵活性，可以丰富句子结构，增加句子的多样性。
定语从句强调句用法
下面总结强调句型的使用：一、it强调句型的构成：It+be+被强调部分+that(强调部分指人做主语时时用who，指人做宾语时用whom)+句子的其他部分。
例如：Mary met an old beggar in the street yesterday.It was Mary who/that met an old beggar in the street yesterday. (强调主语)It was an old beggar whom/that Mary met in the street yesterday.(强调宾语)It was yesterday that Mary met an old beggar in the street.(强调时间状语)It was in the street that Mary met an old beggar yesterday.(强调地点状语)注意：it强调句型不能强调句子的谓语。
二、not…until结构强调句型的构成：It+be+not+until部分+that+句子的其他部分。
例如：He didn't go to bed until his father came back.. 变为强调句型为：It was not until his father came back that he went to bed.注意原句中的didn't go部分中的not提前后，剩下did go变为went.本文开头提到的两个句子都是not..until结构用于强调句型。
那么把这两句话变回正常的语序则为：1)…but he didn't make his most important discovery until after the war. 2)The importance of Fleming's discovery was not fully recognized until World War II. 三、特殊疑问句强调句型的构成：特殊疑问词+be+it+that+句子的其他部分(用陈述语序) 例如：When did you receive the gift？对特殊疑问词when做强调：When was it that you received the gift？注意此句中的received是由did加receive结合而成的。
强调句和定语从句的区别
强调句和定语从句的区别
强调句和定语从句都是英语语法中常见的从句结构，但它们有一些明显的区别。
强调句通常用来强调一个特定的词或短语，以使其更加突出和引人注意。
强调句的结构是：It is/was + 被强调部分 + that/who + 其他部分。
例如：It was John who ate the entire cake. 在这个句
子中，“John”是被强调的部分，强调了他是吃了整个蛋糕的人。
定语从句则用来描述或限制一个名词或代词。
定语从句的结构是：关系代词（that/who/whom/whose）+ 主语 + 谓语 + 其他部分。
例如：The person who called me yesterday was my best friend. 在这个句子中，“who called me yesterday”是定语从句，修饰并限制了“person”的范围，告诉我们是哪个人打电话给了我。
总之，强调句用于强调一个特定的词或短语，而定语从句则用于描述或限制一个名词或代词。
了解它们的区别可以帮助我们更好地理解和运用这两个语法结构。

定语从句和强调句的区别
定语从句和强调句的区别一、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〕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 besiness trip, he brings a lot of living necessities, such astowers, 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in which, at which, for which或at whichAttitudes towards daydreaming are changing in much the same waythat(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。
定语从句和强调句的区分方法
定语从句和强调句的区分方法1.结构不同：定语从句是一个从句，通常修饰一个名词或代词，而强调句是一个完整的句子，用来强调一个句子成分。
例句：The book that I bought yesterday is very interesting.（定语从句）It is me who bought the book yesterday.（强调句）2. 位置不同：定语从句通常位于被修饰的名词或代词之后，而强调句则可位于句首、句中或句末，通常用it或者wh-词引导。
例句：The girl who is wearing a red dress is my sister.（定语从句）It is my sister who is wearing a red dress.（强调句）3. 关键词不同：定语从句通常使用关系词（如that, who, which等）引导，而强调句则使用it is...that...或者it is...who...等结构来强调句子的一些成分。
例句：The movie that I watched last night was amazing.（定语从句）It was the movie that I watched last night that was amazing.（强调句）4.强调的程度不同：定语从句主要用来限定名词或代词，使其更具体，而强调句则是为了给一些成分更多的强调和重要性。
例句：I have a friend who can play the guitar very well.（定语从句，强调的是我有一个会弹吉他的朋友）It is my friend who can play the guitar very well.（强调句，强调的是我的朋友会弹吉他）通过注意以上几个特点，可以帮助我们区分定语从句和强调句的语法结构和意义。
强调句与定语从句
强调句与定语从句篇一：强调句和各从句的区别一、定语从句与名词性从句句式结构用法比较定语从句常易与主语从句、表语从句、宾语从句和同位语从句等名词性从句相混淆。
判断的方法是：由关系代词或副词引起的句子直接充当句中某一成分，即为名词性从句；如果这个句子修饰前面的一个名词即先行词或指代整个句子的内容，即为定语从句。
例1. (1) As is known to everyone, the moon travels round the earth once every month.(2) It is known to everyone that the moon travels round the earth once every month.比较：(1)两个句子之间有连接词，而且由逗号分隔。
根据前一分句意义“正如大家所知道的(众所周知)”分析，该句应用关系代词as引导非限制性定语从句，指代主句整个句子内容。
(2)两个句子之间有连接词that连接。
根据句意分析，that所引起的从句为主语从句，故该句应选用it作形式主语置于句首，引导主语从句。
例2. (1)Shenzhen is no longer what it used to be.(2) Shenzhen is no longer the place that it used to be.比较：(1)句中没有充当表语的名词，故应选用代词what(??样子)引起一个表语从句。
(2)句中表语名词the place 被it used to be所修饰，且充当其句中表语。
故应选用关系代词that指代先行词the place引起一个定语从句。
例3. (1) Please tell me the reason why he didn’t attend the meeting.(2) Please tell me why he didn’t attend the meeting.比较：(1)句中充当宾语的名词the reason被he didn’t attend the meeting所修饰，且充当句中的原因状语。

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。

强调句与定语从句的区别例句
强调句与定语从句的区别例句强调句和定语从句是英语语法中两种常用的修饰句子和名词的结构。
强调句用来强调句子中的某个成分，而定语从句用来修饰名词。
下面是具体的例句，以帮助理解两者之间的区别。

强调句型与定语从句的区别
强调句型与定语从句的区别大家都知道，在高中英语学习中，强调句型和定语从句是高中英语中一个重要的语法项目，是高考重要考点之一。
学生在学习的过程中往往容易将两者混淆。
强调句 (The Emphatic Pattern) 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。
通过各种方式对句子中的某个部分进行强调，从而起到修辞的作用。
英语经常使用的强调结构有：It is (was)+被强调部分(主语、宾语或状语)+that/who...；定语从句（Attributive Clauses）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.如：例句1.（It's ）in the house （that） he lives.（强调句型）例句2.It's the house where he lives.（定语从句）那么，如何来判断这两个句子呢？下面我就上面的例句进行分析，并作以区别。
结合学生在做题中所遇到的问题对强调句和定语从句进行区别：由it引导的句型结构，常可构成强调句或定语从句，两者极易混淆。
一般来说，如果将it is/was...与连接词去掉，句子仍然正确，就为强调句型。
这时，就选用that连接词;否则，就为定语从句，其关系词的选择，应根据先行词与从句的关系而定。
例句 1.It's in the house that he lives.去掉后是：（It's ）in the house （that） he lives.=He lives in the house.例句2.It's the house where he lives.（不克不及是that）否则去掉后是：He lives the house.很明显这是错误的。
比较：(1)该句为强调句。
暗示地点的名词thehouse前有介词与其连用，说明它是一个完整的地点状语。
强调句和定语从句用法
强调句和定语从句用法强调句和定语从句用法大家掌握了强调句和定语从句用法吗？以下是店铺分享的强调句和定语从句用法，一起来吧！第一单元：强调句1. 一个人的实际能力才是企业所真正看重的。

(完整版)定语从句、同位语从句和强调句
必修二Unit1定语从句、同位语从句和强调句➢定语从句和同为语从句的区别1.从词类上区别同位语从句前面的名词只能是idea, fact, news, hope, belief， suggestion， proposal, word，thought， doubt， truth， possibility, promise， order等表示抽象意义的名词。
而定语从句的先行词可以是名词、代词、主句的一部分或整个主句。
如:We are looking into the question whether he is worth trusting.我们正在调查的是他是否值得信赖的问题。
（同位语从句）Word came that he had gone abroad.据说他已经出国了。
(同位语从句）The doctor whom you are looking for is in the room.你找的那位医生在房间里面。
(定语从句,名词the doctor作先行词）Our team has won the game， which makes us very happy.（定语从句，which代表前面提到的整个句子）His mother did all she could to help him with his study.他妈妈尽最大努力帮他学习。
（定语从句，代词all作先行词）2.从性质上区别定语从句是从句对其先行词的修饰或限制，属于形容词性从句的范畴；而同位语从句是从句对前面抽象名词的进一步说明和解释，属于名词性从句的范畴。
如：The news that our team has won the game is true。
我们队赢了那场比赛的消息是真的。
(同位语从句，补充说明news的内容。
）The news （that） he told me yesterday is true。
昨天他告诉我的那个消息是真的。
强调句与定语从句的区别例句
强调句与定语从句的区别例句
强调句与定语从句的区别在于表达方式和句子结构。
强调句是通过特殊的语法结构来强调某个成分或信息，而定语从句是通过一个从句来修饰名词或代词。
下面是符合标题要求的例句：
1. 强调句：正是他的努力，使得这个项目取得了成功。
定语从句：他的努力是使得这个项目取得成功的原因。
2. 强调句：只有他才能完成这个艰巨的任务。
定语从句：只有他能完成这个艰巨的任务。
3. 强调句：这个问题，是我们必须要解决的。
定语从句：这个问题是我们必须解决的问题。
4. 强调句：这本书，是我一直都在等待的。
定语从句：这本书是我一直等待的书。
5. 强调句：他才是真正的英雄。
定语从句：他是真正的英雄。
6. 强调句：只有努力，才能取得成功。
定语从句：努力是取得成功的关键。
7. 强调句：只有你自己才能改变你的命运。
定语从句：你自己能改变你的命运。
8. 强调句：只有经过努力，才能实现梦想。
定语从句：经过努力的人才能实现梦想。
9. 强调句：他说的话，我永远都不会忘记。
定语从句：他说的话是我永远不会忘记的话。
10. 强调句：唯有爱，才能使人快乐。
定语从句：爱是使人快乐的原因。
通过以上例句可以看出，强调句在句子中使用了特殊的语法结构，将要强调的成分放在句首或句末，并使用了特定的词语或语气来强调；而定语从句则是通过一个从句来修饰名词或代词，起到进一步说明或限定的作用。
两者在表达方式和句子结构上有所不同，但都可以用来强调某个成分或信息。
定语从句和强调句讲义
定语从句一．关于定语从句概念知识：什么叫定语？先行词？关系词？所起的作用？——在复合句中，修饰某一名词或代词，充当定语的从句叫做定语从句。
被定语从句所修饰的词叫做先行词，引导定语从句的词叫做关系词，关系词紧跟在先行词之后，在先行词与定语从句之间起连接作用，同时又作从句的一个成分。
二．关系代词that/which/who/whose/whom之间的选用例题：用who, whom, that, which或whose填空。
1.I have a friend _______ likes listening to music.2.Yesterday Emily was wearing the new dress _______ I gave her.3.The man _______ leg broke in a match used to be a football player.4.Kevin is reading a book _______ is too difficult for him.5.The family _______ I'm staying with live in town.6.I know the student _______ article was published.7.Betty, _______ has never been abroad, is studying English very well.8.My parents live in a house _______ is more thatn 100 years old.9.The man _______ is working on the playground is my old friend.知识总结：（一）由关系代词引导的定语从句及其充当的成分关系代词例句that在定语从句中做主语或宾语指物This is the novel that interests me.(作主语）The magazine (that) I bought yesterday is lost.(作宾语）指人The woman that burst out of the room just now wasangry with you.(作主语）The boy (that) we just saw in the library is the monitorof Class Three.(作宾语）which在定语从句中作主语或宾语指物China is a country which has a long history.(作主语）I have lost the book (which) you lent me yesterday.(作宾语）who, whom在定语从句中分别作主语和宾语指人The man who is talking with my father is a policeman.(作主语）He is the man (whom) I visited last week. (作宾语）That is the boy for whom they were searching.(作宾语）whose在定语从句中作定语指人Henry is the boy whose name is the same as ourEnglish teacher's.(作定语）指物The novel whose cover was broken belongs to me.(作定语）（二）先行词指人时，that可与who/whom互换先行词指物时，that课与which互换（三）that与which在从句中作宾语时，经常省略。

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
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. 在非限定性定语从句中，不能用that，而用who, whom 代表人，用which代表事物
答案C. 考点是连词用法。 本题易误选为A. that. 其实本句不 是强调句。若是，去掉It be… that还应是一个完整的句子。 而本句 Green returned to Canada. 不成句。因此本句不是强调句。 It is /was +时间+ since… 其中is<---> has been was <---> had been.
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〕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, such as towers, soap, toothbrush etc.
常考的强调句结构是it 引导的句子。 It is (was) 被强调部分+ that (who) + 句子其他部分。 此结构强调的成分仅限于主语，宾语和状语。 It is from the sun that we get light and heat. It was not until I had read your letter that I understood the true state of affairs. 典型例题 1） It was last night ___ I see the comet（彗星）. A. the time B. when C. that D. which
一、 限定性定语从句 1. That既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
答案C. 强调句的结构是： It +be +强调部分 + that (who) + 主谓句。 强调句的连词只有两个，that和who。当强调的 部分是人，且为句子的主语时，才用 "who"，其余用that。
