when,where,why引导的定语从句的用法1
when， where， why属于关系副词， 都在其引导的定语从句中充当状语， 其具体用法如下：
1.关系副词 when引导定语从句（包括限定性定语从句和非限定性定语从句）修饰表示时间的先行词， 在定语从句中充当时间状语。
例如： I still remember the day when I first met Jennifer.我仍然记得第一次见到詹妮弗的那一天。// Next month, when you’ll spend your summer holidays in your hometown, is approaching. 下个月即将来临， 届时你们将在家乡度暑假。
2. 关系副词where引导定语从句（包括限定性定语从句和非限定性定语从句）修饰表示地点的先行词， 在定语从句中充当地点状语。
例如： This is the office where he worked. 这就是他工作过的办公室。// She is going to live in Macao, where she has some close friends. 她要到澳门去定居， 在那里她有几个密友。
3. 关系副词why引导限定性定语从句修饰先行词reason， 在定语从句中充当原因状语。
例如： I don’t know the reason why he came so late. 我不知道他来得那么晚的原因。// That is the reason why I don’t want to go. 那就是我不想去的理由。// He didn’t tell me the reason why he was so upset.他没有告诉我他为什么那样心烦意乱。
注意：
关系代词与关系副词之间并非毫无关联， 两者之间存在密切的联系。在备考中尤其要注意以下几点：
1. 很多情况下关系副词用“介词＋which/whom”来代替， 其中的介词由先行词或定语从句中谓语动词的形式来决定， 例如：
The day when I met the famous pop star was the greatest day of my life.
The day on which I met the famous pop star was the greatest day of my life.见到这位著名歌星的那天是我一生中最重要的日子。
I shall never forget those years when I lived with her.
I shall never forget those years during which I lived with her.
我将永远不会忘记我跟她生活的那些岁月。
This is a hall where the medical conference will be held.
This is a hall in which the medical conference will be held.
这是礼堂， 医学会议将在此召开。
2. 并非先行词表示时间或地点时都分别用when或where来引导相应的定语从句， 若关系词在修饰表示时间或地点的先行词的定语从句中充当主语、 宾语等而不是状语时， 需用which或that引导相应的定语从句。例如： Do you still remember the days which/that we spent together in school? 你还记得我们一起在学校度过的"那些日子吗？
先行词the days表时间， 但是其定语从句的引导词在定语从句中作宾语而不是状语， 因此不能用when而应该用which或that。
3. that有时可以代替定语从句中的关系副词when， where， why， 且that常可以省略， 例如： This is the time （when/that） he arrived. 这是他到达的时间。

where的定语从句2
Where引导定语从句，先行词不一定都表示地点
1. We will discuss a number of cases __ beginners of English fail to use the language preperly.
A.which B.as C.why D.where
2.He was driving so fast as to get himself into a dangerous situation ___he is likely to lose the control over his car.
A.which B.as C.why D.where
两道题都选where ，但是case, situation都不是地点，如何理解？
在“先行词不是表示地点的名词”的前提下，如何判断是否使用关系副词where来引导定语从句的问题是一个高频考点。就是说，关系副词where所指代的先行词不只是表示地点的名词。
用Where引导定语从句，先行词不一定都表示地点按照通常的理解，当where引导定语从句时，它的先行词就是表示地点的名词，但事实并不是我们想象的那么简单。很多情况下，where所指代的先行词并不表示地点。
请看以下几个例句：
1. Remember that the best relationship is one where your love for each other is greater than your need for each other.
请记住，最深的感情关系表现为彼此间的"爱超过彼此间的需要。
点评：这里where引导的定语从句修饰先行词one，也就是relationship (此处one指代的是relationship)。Relationship不是地点名词，但此处却用了where来引导，where在这里表示“在这样的感情关系下”。从定语从句的结构来看，定语从句不缺主语和宾语，引导词where在从句中充当的是状语。
2. Cheating is most likely in situations where the vital interests are high and the chances of getting caught are low. 欺诈行为在这种情况下最有可能发生：利益重大，而且欺诈行为被发现的可能性小。
点评：句中的先行词是situations，表示“情形，情况”，引导词依然用的是where，表示“在这种情况之下”。这里的定语从句也是不缺主语或宾语的，where在从句中充当的是状语。
3. Until such time as mankind has the sense to lower its population to the point where the planet can provide a comfortable support for all, people
will have to accept more “unnatural food”.除非人类能够意识到要把人口减少到这样的程度——使地球能为所有人提供足够的食物，否则人们将不得不接受更多的“人造食品”。
点评：这里的先行词是point，表示“某种程度，某种状况”，引导词where指代point，表示“在这种程度下”。这里定语从句也是不缺主语和宾语的，where在从句中充当的仍然是状语。
从上面三个例句中，我们可以发现以下两点：第一，即使先行词不是表示地点的词，定语从句也能够使用关系副词where来引导；第二，上面三个例句中，where分别指代relationship、situation和point，分别表示“在……关系中”“在……情况下”“达到……程度”，这些词虽然不是表示地点的名词，但在从句中表达的是“某个点或状态”的含义。我们可以把这类名词解释成“含有抽象地点意义的名词”，此类词也能用关系副词where来进行引导。
先行词不表示地点时，如何判断是否使用Where引导定语从句当先行词不是表示地点的名词时，该如何判断是否使用where引导定语从句呢？由上文给出的例句可知，含有抽象地点意义的名词能用关系副词where来引导，并且在每个例句的点评中都反复强调“定语从句不缺主语和宾语，where在从句中充当的是状语”。
由此，我们可以大胆地进行引申和归纳，提出“当先行词不表示地点时，使用where引导定语从句”的判断方法。首先，判断定语从句的结构：定语从句应该不缺少主语和宾语，而是缺少状语。其次，观察先行词：先行词是除了时间名词(在这种情况下会用when)和原因名词(在这种情况下会用why)以外的其他任何名词。第二个条件之所以成立，是因为定语从句中的状语成分一般就是由when、where和why等三个引导词来引导的。
为了更深刻地理解这种判断方法，请看以下几个例句：
4. English is a fixed-word-order language where each phrase has a fixed position. 英语是一种“词序固定”的语言，这种语言的特点就是每个短语都有固定的位置。
点评：首先，我们来判断定语从句“each phrase has a fixed position”的结构：该从句并不缺少主语和宾语，但是缺少状语。其次，我们来看先行词：先行词是fixed-word-order language, 它既不表示时间，也不表示原因。由此可知，此处用where来指代先行词，表示“在词序固定这样的语言中”。
5. At the Academy, Plato taught the students through the use of debates, where two or more people took different ideas of an argument. 在学院里，柏拉图采用的教学方法是组织辩论，在辩论中，两个或多个学生各持一方观点。
点评：首先，我们来判断定语从句“two or morepeople took different ideas of an argument”的句子结构：该从句不缺少主语和宾语，但是缺少状语。其次，我们来看先行词：先行词是debates，它既不是时间名词，也不是原因名词。由此可知，此处应用where引导定语从句，表示“在辩论中”。
6. However, being enthusiastic isn"t for everyone and no one likes false enthusiasm, where a person pretends to be excited even about small points.然而，热情并非适合每一个人，而且也没有人喜欢那种连区区小事都假装兴奋的假热情。
点评：首先，我们判断定语从句“a person pretends to be excited even about small points”的句子结构：该从句不缺少主语和宾语，但是缺少状语。其次，我们来看先行词：先行词是false enthusiasm，它既不是时间名词，也不是原因名词。因而，此处用where来引导定语从句，表示“在虚假的热情这种状态下”。
通过对上面三个例句的点评，相信读者已经能够掌握在先行词不表示地点的情况下，如何判断是否使用where来引导定语从句了。此外，我们需要仔细体会例句中where指代先行词时所表达的含义，分别是“在……样的语言中”“在……中”“在……样的状态下”，这些含义与第一节所举的例子类似，都带有抽象的地点意义。因而，我们在日后的学习和考试中应当谨记：
用where引导的定语从句，先行词不一定是表示地点的名词，因为先行词也可能是含有抽象地点意义的名词。由此，我们总结如下：
先行词是表示“地点”或任何含有“抽象地点意义”的名词用where引导定语从句。
where的定语从句3
where先行词表示时间、地点、原因，但关系词指代先行词在定语从句中充当主语或宾语时，应用关系代词that或which.如：

我不会忘记充满悲哀的1976年。

why引导的定语从句例句2
关系副词why引导限定性定语从句修饰先行词reason， 在定语从句中充当原因状语。例如： I don’t know the reason why he came so late. 我不知道他来得那么晚的原因。// That is the reason why I don’t want to go. 那就是我不想去的理由。// He didn’t tell me the reason why he was so upset.他没有告诉我他为什么那样心烦意乱。
1.在reason作先行词的定语从句中，若从句表原因，一般用why引导定语从句，why可以用for which替换。why还可省去。
why=for which
(for在这里是表原因的)
The reason why (for which) he has resigned is poor health.
(他辞职的理由是健康状况不佳。)
reason是名词在句子中充当先行词，而why后所接的定语从句是用来修饰reason的。
原因是他的健康情况不是很好，什么原因那?奥，，原来是他辞职的原因。(这句话中他辞职来修饰原因)
2.当reason作主语带有定语从句修饰时，其后的表语从句通常用that不用because。
The reason why(符合第一条) he didn"t come in time was that he didn"t feel well.
他没有来的原因是因为他不舒服。
就是说后面跟的是一句句子要+that
why为引导词，reason为先行词
这个知识点是在强调，当主语有定语从句时，表语从句(就是be动词后边的那个句子)为了避免重复就不用because引导，而用that
这边如果大家做选择，请记住选that 不是because
3.当reason用作定语从句的宾语时，引导词用that/which,而且that/which可省去。
The reason (that/which) he gave for being late was that they were held up in a traffic jam.
他给出的迟到原因是由于他们被交通阻塞给耽误了。
注意：此时的引导词不是because，不是because，不是because，而是that/which，并且还可以省略。
就像在例句中，reason是gave的宾语，定语从句没有用why，而用了that/which。并且其后的表语从句用that引导，而没有用because(详细解释见2)
归根揭底because在定语从句选择题中选择可能性比较少
4.注意句型
This/That"s why…=This/That"s the reason why…(记住这个句型就好啦)
That"s why he did it.(不用that代替why)
= That"s the reason why he did it.
这就是他为什么做这事的原因。
why引导的定语从句例句3
when/where/why引导的定语从句
when， where， why属于关系副词， 都在其引导的定语从句中充当状语， 其具体用法如下：
1.关系副词 when引导定语从句（包括限定性定语从句和非限定性定语从句）修饰表示时间的先行词， 在定语从句中充当时间状语。
例如： I still remember the day when I first met Jennifer.我仍然记得第一次见到詹妮弗的那一天。// Next month, when you’ll spend your summer holidays in your hometown, is approaching. 下个月即将来临， 届时你们将在家乡度暑假。
2. 关系副词where引导定语从句（包括限定性定语从句和非限定性定语从句）修饰表示地点的先行词， 在定语从句中充当地点状语。
例如： This is the office where he worked. 这就是他工作过的办公室。// She is going to live in Macao, where she has some close friends. 她要到澳门去定居， 在那里她有几个密友。
3. 关系副词why引导限定性定语从句修饰先行词reason， 在定语从句中充当原因状语。
例如： I don’t know the reason why he came so late. 我不知道他来得那么晚的原因。// That is the reason why I don’t want to go. 那就是我不想去的理由。// He didn’t tell me the reason why he was so upset.他没有告诉我他为什么那样心烦意乱。
注意：
关系代词与关系副词之间并非毫无关联， 两者之间存在密切的联系。在备考中尤其要注意以下几点：
1. 很多情况下关系副词用“介词＋which/whom”来代替， 其中的介词由先行词或定语从句中谓语动词的形式来决定， 例如：
The day when I met the famous pop star was the greatest day of my life.
The day on which I met the famous pop star was the greatest day of my life.见到这位著名歌星的那天是我一生中最重要的日子。
I shall never forget those years when I lived with her.
I shall never forget those years during which I lived with her.
我将永远不会忘记我跟她生活的那些岁月。
This is a hall where the medical conference will be held.
This is a hall in which the medical conference will be held.
这是礼堂， 医学会议将在此召开。
2. 并非先行词表示时间或地点时都分别用when或where来引导相应的定语从句， 若关系词在修饰表示时间或地点的先行词的定语从句中充当主语、 宾语等而不是状语时， 需用which或that引导相应的定语从句。例如： Do you still remember the days which/that we spent together in school? 你还记得我们一起在学校度过的那些日子吗？
先行词the days表时间， 但是其定语从句的引导词在定语从句中作宾语而不是状语， 因此不能用when而应该用which或that。
3. that有时可以代替定语从句中的关系副词when， where， why， 且that常可以省略， 例如： This is the time （when/that） he arrived. 这是他到达的时间。

when,where,why引导的定语从句的用法3篇（扩展3）
——where的定语从句用法3篇
where的定语从句用法1
例1)I went to a small town. I met my boyfriend in that town.
在后面的简单句中，in that town是地点状语，所以可以用 where代替in that town，I met my boyfriend 放在先行词(也就是定语从句所修饰的词)town的后面。
I went to a small town where I met my boyfriend.我去了一个小镇，在那里我遇见了我的男朋友。
例2)I went to a small town. It is very quiet and peaceful.
这两句合成定语从句就是 it去掉，用which/that，来代替，定语从句which/that is very quiet and peaceful 来修饰先行词town.
I went to a small town which is very quiet and peaceful.
I went to a small town that is very quiet and peaceful.
为什么主句都一样，修饰的也是同一个先行词town，第一个就用连接词where，而第二个就用连接词which或that呢?在定语从句中，一定要弄清句子成分。
I met my boyfriend in that town. In that town 是做地点状语。
It is very quiet and peaceful. It 是做谓语动词is的主语。
所以例句1连接词where代替的是地点状语，in that town.例句2 连接词that或which是代替主语it，也就是town.
在定语从句中 where一定翻译在那里，然后再翻译定语从句，翻译完之后，感觉通顺，定语从句一定是一个完整的简单句。
例3)The street where the parade begins is Broadway.
那条街道是百老汇街，在那里开始了
在这个从句中，the parade begins 是一个完整的简单句，不缺宾语 因为begin是不及物动词。(以后会讲及物动词和不及物动词)。
例4)The site where the concert will take place is Golden Park.
那个地点是golden park，在那里举行音乐会。
练习：把下面几个句子补充完整。
1，we went to a hospital which___________________.(which 指代从句宾语)
We went to a hospital where _____________________.
We went to a hospital which______________________.(which指代从句主语)
2，Lisa cleaned the classroom where___________________.
Lisa cleaned the classroom that _____________________.
Lisa cleaned the classroom that __________________.

(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短语动词中的介词不可与动词拆开，在定语从句中其介词不可前置，只能放在其动词之后。

限制性定语从句与非限制性定语从句的.区别：
限制性定语从句
非限制性定语从句
All the students who study hard have passed.学习努力的学生都考试及格了。(只有努力的及格了，不努力的没及格。) All the students ,who study hard have passed.所有的学生都及格了，他们学习努力。(没有人不及格，这些学生都很努力。)
从句是先行词不可缺少的定语(如去掉，主句意思就不完整或不正确。) 从句是对先行词的附加说明(如去掉，主句意思仍清楚，不受影响。) 与主句关系密切，不用逗号 与主句关系不十分密切，用逗号与主句隔开译为汉语时，从句译在先行词前，与先行词用“的”连接 译为汉语时，从句放在主句后面关系代词that可以代替who、whom(指人)、which(指物) 关系代词不用that,只用who、whom(指人)、which(指物) 关系代词代替宾语时可以省略 关系代词不能省略关系代词as和which
先研究下面两个例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出来，这头象像条蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考试不及格，这使得他父亲很生气。
这两个例句中，as和which所代表的都是整个主句所表示的内容。但有两点不同之处：
1. 在形式上as引导的非限制性定语从句可位于主句的后面，也可位于主句的前面;而which引导的非限制性定语从句只能位于主句的后面，不能位于主句的前面。
2. 在意义上，as引导的定语从句和主句的关系一般为一致关系，常译为“正如……”，“就像……”，而which引导的定语从句和主句的关系是因果关系，或which引导的定语从句是对主句的评论。因此，在意思通顺的情况下，which可代替as，而as许多时候不能代替which，如句○2。再如：
1.He was late again, as / which we had expected. =As we had expected, he was late again. 正如我们所料，他又迟到了。/他又迟到了这是我们早就料到的。
2. The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期没有打扫了，因此整条街很脏。(不用as)
3.The young man cheated his friend of much money, which was disgraceful. 那年轻人诈骗了他朋友许多钱财，这是不光彩的。(不 用as)
4.He takes exercise everyday, which has done a lot of good to his health. 他每天运动，这对他的身体很有好处。(不用as)
5.As has already been pointed out, English is rather difficult for a foreigner. 正如已经指出的那样，英语对于初学者说，是相当难学的。在such…as…、the same…as…、 as…、 as many…/much as…等结构中,as不能用which代替。如：
1.Such books as this are too difficult for beginners. 这样的书对于初学的人来说是太难了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大楼里。
3.He knows as many people as are present at the meeting. 他认识所有到会的人。
4.That day we all got up early as usual. 那天我们和*时一样，都起得很早。
“One of the +复数名词”后面定语从句中谓语单复数情况
这一结构后面的定语从句的谓语动词通常用复数形式，跟定语从句所*近的那个复数名词在数上保持一致。如：
1. That is one of the books that are required for study at school.
2. This is one of the most wonderful novels that have been published since 1990.
3. She is one of the few persons who know Spanish .
4. This is one of the most famous plays that were written in the thirties,
如果one of +复数名词这一结构前面带有the only、the very之类的限定语，后面定语从句的谓语动词则要用单数形式，这是因为定语从句在意义上修饰的是而不是那个复数名词。如：
1.He is the only one of the teachers who knows French in our school.( 修饰the only one)
He is one of the teachers who know French in our school.( 修饰the teachers)
2.This is the only one of the rooms that is free now. (修饰the only one)
This is one of the rooms that are free now. (修饰rooms)
as与which引导的定语从句
两者均可引导非限制性定语从句，有时可以互换，但下列情况多用as。
1. 关系代词引导的定语从句居句首时。 As we all know, the earth is round.
2. 当与such或the same连用时，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 当从句和主句语义一致时，用as，反之则用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在从句中作主语时，后面常接行为动词的被动语态，如be known，be said，be reported等，如从句中行为动词是主动语态，一般要用which作主语。
She has been late again, as was expected.
Tom has made great progress, which made us happy.
英语的定语从句总结2
一、关系代词引导的定语从句
1、由who, whom, that，Whose引导的从句
这些词代替的先行词是人的名词或代词，who作主语指人，whom作宾语指人，that既可作主语又可作宾语(作宾语可以省略)，可以指人也可以指物。Whose 用来指人或物，只用作定语。
(1) Is he the man who/that wants to see you? 他是那个想见你的男人吗?(who/that在从句中作主语)
(2) He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。(whom/that在从句中作宾语)
(3) The man whom you spoke to just now is our English teacher 你刚刚说话的那个男人是我们的英语老师
(4) he man whose son is a doctor is our professor. 那个儿子是医生的男人是我们的教授。
2、由which, that引导的从句
它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，作宾语时可以省略，例如：
(1) Prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。(which / that在从句中作主语)
(2) The package (which / that) you are carrying is about to come unwrapped. 你拿那个包裹快要散开了。(which / that在从句中作宾语)
注意： 代表物时多用which，但在下列情况中用that而不用which：
a)先行词是anything, everything, nothing , none等不定代词时;
b)先行词由every, any, all, some, no, little, few, much等修饰时，这时的that常被省略;
c)先行词前有序数词或被形容词最高级修饰时;
d)先行词中既有人又有物时;
e)整个句中前面已有which，who,that时;
f)当先行词为物并作表语时;
g)先行词为one时;
h)先行词同时又被the only,the very,the same修饰时;
二、关系副词引导的定语从句
1、when指时间在定语从句中做时间状语也可做连接词用 I still remember the day when I first came to the school.
2、where指地点在定语从句中做地点状语 Shanghai is the city where I was born.
3、why指原因在定语从句中做原因状语 ，用在reason 后面。 Please tell me the reason why you missed the plane.
常见考法
对于定语从句的考查，多以单选的形式考查学生灵活运用的能力。一般情况下，常从关系词的意义和功能的角度考查，重点是that,which,who引导的定语从句。
典型例题：Youre the only person ______Ive ever met ______could do it.
A. who B. whom C. whom D. who
解析：先行词person后有两个定语从句,第一个从句省略了关系代词whom.因为, whom作从句中met的宾语,可以省略.第二个从句who could do it.who在从句中作主语,不可省略.
答案：D
误区提醒
当表示时间或地点的名词作先行词时，要判断出它们在从句中作状语还是主语或宾语。作状语时用关系副词，反之用关系代词。
典型例题：I can never forget the day _______ we worked together and the day ______ we spent together.
A. when; which B. which; when C. what; that D. on which; when
解析：. 两个先行词the day都是表示时间的名词,但第一个空白处要填的关系词在从句中作状语,因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which或that来引导定语从句.
答案：A

“One of the +复数名词”后面定语从句中谓语单复数情况
这一结构后面的定语从句的谓语动词通常用复数形式，跟定语从句所*近的`那个复数名词在数上保持一致。如：
1. That is one of the books that are required for study at school.
2. This is one of the most wonderful novels that have been published since 1990.
3. She is one of the few persons who know Spanish .
4. This is one of the most famous plays that were written in the thirties,
如果one of +复数名词这一结构前面带有the only、the very之类的限定语，后面定语从句的谓语动词则要用单数形式，这是因为定语从句在意义上修饰的是而不是那个复数名词。如：
1.He is the only one of the teachers who knows French in our school.( 修饰the only one)
He is one of the teachers who know French in our school.( 修饰the teachers)
2.This is the only one of the rooms that is free now. (修饰the only one)
This is one of the rooms that are free now. (修饰rooms)
as与which引导的定语从句
两者均可引导非限制性定语从句，有时可以互换，但下列情况多用as。
1. 关系代词引导的定语从句居句首时。 As we all know, the earth is round.
2. 当与such或the same连用时，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 当从句和主句语义一致时，用as，反之则用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在从句中作主语时，后面常接行为动词的被动语态，如be known，be said，be reported等，如从句中行为动词是主动语态，一般要用which作主语。
She has been late again, as was expected.
Tom has made great progress, which made us happy.
when,where,why引导的定语从句的用法3篇（扩展5）
——whether引导的条件从句3篇
whether引导的条件从句1
whether：对于某件事情的不确定性，表示的怀疑。
whether
1. (引导名词从句)是否
Ask him whether he can come or not.问问他是否能来。
I dont know whether you like flowers, sir.
先生,我不知道您是否喜欢花。
2. (与or连用,引导状语从句)不管是...(或是)
Well go on with the work, whether we can find the necessary tools or not.
不管我们能否找到所需的工具,我们要把这件工作做下去。
在引导定语从句时，一般情况下whether和if都可使用，但whether的适用范围要比if广，实在不知道应用什么的时候，选whether。
例如从句若出现了选择项：A or B，只能用whether而不能用if
但要注意，从句为否定句时，只能用if，而不能用whether
一、在英语句子中，whether和if本身有意义(都表示“是否”)，在从句中不可省略。它们的区别最主要的"就是：whether 可以引导所有的名词性从句，而if只能引导宾语从句。例如：
1. I didnt know whether he would attend the concert.
我并不知道他是否会参加音乐会。(宾语从句可用if代替whether)
2. The question is whether its worth trying.
问题是值不值得一试。(表语从句，不能用if代替whether)
3. Whether she comes or not makes no difference.
她来不来都没有关系。(主语从句，不可用if代替whether)
4.He must answer the question whether he agrees to it or not.
他必须回答他是否同意。(同位语从句，不可用if代替whether)
whether引导的宾语从句可作介词的宾语，而if则不能。
5. It all depends on whether they will support us.
这完全取决于他们是否支持我们。(不能用if)
二、if引导状语从句，也可引导宾语从句。如果用if会引起歧义，应避免使用if，而用whether。
Please let me know if you want to join us.
请告诉我你是否想加入我们。(这样就看成是宾语从句，if表示“是否”) 若翻译成:如果你想加入我们的话，请告诉我一声。(if引导的从句可看成是条件状语从句，if表示“如果”) 所以，为了避免引起歧义，此时最好用whether表示“是否”。
三、whether引导主语从句时，既可以直接位于句首，也可以位于句末;if引导主语从句时只能用于it作形式主语的从句中。例如：
1. Whether we need it is a different matter.
2. It is a different matter whether(if)we need it.
四、在宾语从句中，当表示“是否”时，whether与if可以互换，但如果从句中有or not 时只能用whether 引导。例如：
I don’t know whether he will come or not.
五、whether引导的从句可以充当介词宾语，if则不行。
I worry about whether i hurt her feelings.
六、whether引导的从句可以作名词的同位语，if则不行。
The question whether we need it has not been decided.
七、可能造成歧义时，用whether而不用if。
1. please let me know whether you are coming.
请告诉我你是否要来。(whether引导宾语从句)
2. please let me know if you are coming.
如果你要来，请告诉我。(if引导状语从句)

that引导定语从句的例句3
一、as用作关系代词引导定语从句
1. as 引导非限制性定语从句，一般不指代某个具体的名词或代词，而是代表整个主句或主句的一部分。这种从句可放在主句之前，也可以放在主句之后，有时还可以放在主句的中间。如：
As is reported in the newspapers, talks between the two countries are making progress. 正如在报纸上所报道的，两国间的谈判有所进展。
Grammar is not a set of dead rules, as has been said above. 如上所说，语法不是一套死条文。
Spiders are not insects, as many people think, nor even nearly related to them. 蜘蛛不是昆虫，尽管许多人都这样认为，它甚至与昆虫几乎没有联系。
2. as 引导限制性定语从句，主要用于the same…as（与……相同），such…as（像……一样），as…as（与……一样）。如：
She knew he felt just the same as she did. 她知道他的感受和她一样。
Such a man with a good temper as Mr. Li is is easy to get along with. 像李先生这样好脾气的人是容易相处的。
He smokes as expensive a cigarette as he can afford. 他抽一种他买得起的最贵的烟。
二、as作为从属连词引导时间状语从句
表示“当……的时候”或“一边……一边”，强调主句的动作和从句的动作同时发生。如：
I saw him as he was getting off the bus. 当他下公共汽车的时候我看见了他。
The boy was singing a popular song as he was bicycling. 这男孩边骑车边唱歌。
As she grew older, she became less active. 当她长大一点的时候，就变得不那么活泼了。
三、as作为从属连词引导原因状语从句
as 引导的原因状语从句常放在主句前，表示“因为，由于”。如：
As she is a model teacher, she gives a good example to others. 因为她是一名模范教师，她给其他人树立了一个好的典范。
As he wasn’t ready in time, we went to the cinema without him. 由于他没有及时准备好，我们就去看电影了，没有等他。
三、as作为从属连词，引导让步状语从句
as引导让步状语从句比较特别，它要求将主语和谓语或谓语的一部分倒装。如：
Old as he is, he is still full of energy. 尽管年纪大了，但他依然精力充沛。
Try as she may, she never succeeds. 尽管她很努力，但总是不成功。
Much as I admire Mr. Wang as a poet, I don’t like him as a man. 尽管我喜欢王先生的诗歌，但我不喜欢他的为人。
注：当倒装后置于句首的名词为单数可数名词时，习惯上不带冠词。如：
Boy as he was, he was made king. 尽管他还是个孩子，却被立为国王了。
四、与其他词搭配使用构成从属连词引导从句
1. as if / as though。表示“好像，仿佛”，引导表语从句或方式状语从句。如：
It looks as if / as though it is going to snow. 看起来要下雪啦。
He looks as if / as though he had seen a ghost. 他的脸色看起来好像他看见了鬼。
He talks as if /as though he knew everything about it. 他说话的口气好像他已经全部都知道了。
2. as [so] long as。“只要”，引导条件状语从句。如：
As [So] long as you can keep away from them, you will be safe. 只要你能远离他们，你就安全了。
I’m happy as long as you are happy. 只要你幸福，我就感到幸福了。
3. as [so] far as。表示“在……的范围内”，引导限制状语从句。多用于下列结构：as [so] far as I know（据我所知），as [so] far as I can see, as [so] far as I’m concerned（依我看）。如：
As [So] far as I know, the couple have been abroad for about five years. 据我所知，这对夫妇已经出国约五年了。
There’s only one thing to be done now, as far as I can see. 依我看。现在只有一件事情要做。
4. as soon as。表示“一……就”，引导时间状语从句。如：
As soon as he got off the plane, he telephoned her girl friend. 他一下飞机就给他的女朋友打了个电话。
He started as soon as he received the news. 他一得到消息就出发了。
总之，由于as的用法复杂，同学们在学习时一定要注意比较其在不同句子中的作用，判断其连接的是什么样的从句，多做一些关于相关练习，这样便可掌握其用法了。

Find out the attributive clause in the song and try to sing it. The One You Love By Glenn Frey
I know you need a friend
Someone you can talk to
Who will understand what you"re going through When it comes to love
There"s no easy answer
Only you can say what you"re gonna do
I heard you on the phone
You took his number
Said you weren"t alone, but you"d call him soon Isn"t he the guy
The guy who left you crying"
Isn"t he the one who made you blue
When you remember those nights in his arms You know you"ve gotta make up your mind Are you gonna stay with the one who loves you Or are you going back to the one you love
Someone"s gonna cry when they learn they"ve lost you Someone"s gonna thank the stars above
What you gonna say when he comes over
There"s no easy way to see this through
All the broken dreams
All the disappointments
Oh girl -- What you gonna do
Your heart keeps saying" it"s just not fair
But still you"ve gotta make up your mind
Are you gonna stay with the one who loves you Or are you going back to the one you love
Someone"s gonna cry when they learn they"ve lost you Someone"s gonna thank the stars above
