如果句子中缺主语，指人用，指物用；
如缺宾语，指人用，指物用；
如缺时间状语用；地点用；原因用；方式用；
定语用what或which；
什么都不缺用。whether 和if
（一）that 和 what的选用：
What 起连接作用外，还在名词性从句中充当成分。
That 只起连接作用，不充当任何成分。

_____ he told us true ？

不能使用if 的情况：
a. 主语从句
b. 表语从句
c. 同位语从句
d. 介词后的宾语从句
e. whether to do 做动词宾语不能用if to do.
f .whether or not 连在一起引导宾语从句时不用if.

五、同位语从句的引导和辨别
1.同位语从句的格式：n.+ 连接词 + 从句
2.能接同位语从句的名词有：fact、idea, news, information, order, belief, suggestion, advice 等.
3.连接词通常是that,也可根据含义选用 whether, what, when, where 等来引导同位语从句.
1. I have no idea _________ he comes from.
2. He can’t answer the question ________ he got the money.
gave us many suggestions ________ we should get up earlier and take more exercise.
have no doubt ________ he will win.
5. I have some doubt ________ he will win.
（六）同位语从句和定语从句的区别
1.定语从句是先行词的修饰语，它不涉及先行词的具体内容。定语从句中that起连接作用，在定语从句中充当一个句子成分，充当从句的宾语成分时可省略。
2.同位语从句对中心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that 在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略. expressed the hope that they had expressed.
2. We expressed the hope that they would come to China again.
information has been announced that more middle school graduates will be admitted into university.
information that he revealed at the meeting is of great value.
（七）在表示“命令、建议、坚持、要求”的名词性从句中，要用“should+动词原形”形式，should可以省略。. I made a suggestion that he (should) go there at once.
I suggested that he (should) go there at once.
The suggestion was that he (should) go there at once.
I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发\ He insisted that he _____ the money and ____ he ____ set free.

C. didn’t steal , that , should be
D. ste al , /
was
(八）宾语从句的时态呼应
1. 如果主句时态是现在时或将来时,从句谓语可根据句意需要而选用任一种时态.
a .他相信他的梦想总有一天会实现的. He believes _________________________ .
b .请告诉我你昨天这个时候在干什么. Please tell me _________________________. (九）名词性从句中一律使用陈序语气。
. He asked how much I paid for the violin.
I want to know what he has told you. 我想知道他告诉了你什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。(十) 疑问词+ever 与no matter + 疑问词的区别：
疑问词+ever可以引导________________或_________ .
Whoever breakes the law must be punished .
或：Whoever breakes the law, he must be punished .
no matter + 疑问词只能引导_________________________.
No matter who breaks the law, he must be punished.

1．时间状语从句 常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the instant, immediately , directly, no sooner … than, hardly …when, scarcely … when I didn’t realize how special my mother was until I became an adult. While John was watching TV, his wife was cooking. The children ran away from the orchard(果园), the moment they saw the guard. No sooner had I arrived home ,then it began to rain. Every time I listen to your advice, I get into trouble. 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories.
Wherever you go, you should work hard. 地点状语从句 §4地点状语从句 (adverbial clause of place) 地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型，例如： 句型1：Where＋地点从句，（there）＋主句。 【注意】此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。例如： Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的。 They were good persons. Where they went, there they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。 You should have put the book where you found it. 你本来应该把书放回原来的地方。 Where the Communist Party of China goes, there the people are liberated.哪里有了中国共产党，哪里人民得解放。 句型2：Anywhere/ wherever＋地点从句，＋主句。
英语中定语从句的基本用法(一) 摘要]本文通过实例浅析了英语中定语从句的基本 用法,如有不当之处,望大家批评指正。 关键词]定语从句用法宾语主语 英语,作为一门学科,每天有很多人在其中徜徉,可是也有 很多人虽为它倾注了很多精力却依然觉得举首无措?的确,在 英语中有很多的学问,需要我们去了解和掌握,下面就其中的某 个方面——定语从句,通过实例,分析一下它的基本用法,和大 家一起学习。 在句子中用作定语的从句称为定语从句。定语从句通常位 于它所修饰的名词或代词之后,这种名词或代词称为先行词。引导定语从句的关联词为关系代词和关系副词。关系代词在定语 从句中可以用作主语、宾语、表语、介词宾语和定语等等;关系副词在定语从句中只用作状语。 I.由关系代词who,whom,whose,which,that引导的定 语从句。 i.who代替人,在从句中作主语。 e.g.Amanwhodoesn’ttrytolearnfromotherscannot hopetoachievemuch. 一个不向别人学习的人是不能指望有多大成就的。 ii.whom代替人,在从句中作宾语,通常可以省略。 e.g.Theengineerwhomwemetyesterdayhaveworked outanewautomaticdevice. 我们昨天碰到的工程师研制出了一种新型的自动化装置。 iii.whose代替人或物,在从句中作定语。 e.g.MadamCurieisagreatscientistwhosenameis knownallovertheworld. 居里夫人是一位世界闻名的伟大科学家。Theyliveinthehousewhosedoorandwindowsareall broken. 他们住在一间门窗都已破败不堪的房子里。 iv.which代替物,在从句中作主语、宾语或介词宾语。作宾 语时,通常可以省略。 e.g.Adirectcurrentisacurrentwhichflowsinone directiononly. 直流电是沿着一个方向流动的电流。Themusictowhichwelistenedlastnightwaswrittenby myfather. 我们昨晚欣赏的音乐是由我父亲写的。 v.that代替人或物。在从句中作主语或宾语,但不能作介 词宾语。作宾语是通常可以省略。 e.g.HeistheonlyoneamongusthatknowsEnglish. 他是我们中间唯一懂英语的人。ThecarthatalmostcrashedintomebelongedtoBrown.
一、在名词从句中连接词which 有两种词性, 常用来引导宾语从句： 1. [连接代词] 哪个 1）用作从句的主语，如： He wanted to know which was on the table. 他想知道哪一个在桌子上。 2) 用作从句的宾语，如： He asked me which I liked best. 他问我最喜欢哪一个。 2. [连接形容词]放在名词前作定语，表示“哪个XX，哪些XX”，如： Do you wnow Which country is the largest? 你知道哪国家一个最大? Could tell me which children made him still more angry. 能告诉我那些 孩子使他更加生气了。 二、which 除引导上述宾语从句外，还可以引导主语从句和表语从句。 1. 主语从句(常用形式主语it) It was clear which children made him still more angry. 显而易见那些孩子使他更加生气了。 It is known to us which he liked best. 众所周知他最喜欢哪一个。 2. 表语从句 That was which children made him still more angry. 那就是那些孩子使他更加生气了。 This is which he liked best. 这就是他最喜欢哪一个。 三、which 与what 的区别 用在名词从句中，which 意思是“哪一个/那一些”，what 意思是“所...的”，后者等于“先行词+关系代词”，如你的补充问题就需要选择what： It's quite different from what I read last month. = It's quite different from (the one that) I read last month. 这本书与我上周所读过的那一本区别很大。 1.that在所有名词性从句中无成分无意义。 2.which强调哪一个，有一个选择的范围。 从句中from后边缺宾语，所以要选择的是宾语从句的引导词，首先that引导宾语从句时，不做介词宾语（除了in,except,but) 其次read后边缺宾语，也就是从句中缺成分，参见上面第一条，所以排除that.B选项which指哪一个，这里
状语从句连词总结 1 时间状语从句： when当……时候 while 当……时候（动词只能是延续性动词） as当……时候（经常表示一边……一边……） after/before在……之后/之前 until/till直到……（即某一持续性行为持续到某一时间点） since/ever since自从……（即子某一时间点以来，常用完成时态或完成进行时） 名词性短语the time the moment the minute the day the year the first/second time each time每次every time每次next time下次any time在任何时候whenever不管什么时候 by the time到……时候（即指到某一时间点为止，主句常用完成时态） 一……就……as soon as once immediately directly instantly 还没来得及……就……hardly……when no sooner……than as long as长达…… 非时间状语从句：动词ing形式；at……形式；on doing/on sth形式 2地点状语从句 where在哪里，在什么地方 wherever无论在哪里 anywhere无论何处everywhere 到处，处处nowhere 无处，任何地方都无 to/in/from the place（s）where或to/in/from any place where 3原因状语从句 because（语气最强）因为，多置于主句之后 as（语气最弱）因为，多置于主句之前 since语气较弱，常表示对方已知的事实，相当于“既然” now （that）既然 for the reason that因为（that引导的是同位语从句，先行词为reason） in that由于某种原因，多用于书面语 seeing that因为，鉴于 4目的状语从句 in order that以便 so （that）为了 for fear that惟恐，以防 in case以防万一有某种情况发生 5结果状语从句 so （that）所以 so……that……结构 such……that……结构
一、基本概念： 在复合句中，修饰某一名词或代词的从句叫定语从句。如： Do you know the man who spoke at the meeting just now? That is the house where he lived ten years ago. 定语从句所修饰的词叫先行词；定语从句一般用关系代词或关系副词来引导，关系词放在先行词与定语从句之间起连接作用，同时又作从句中的一个成分。 引导定语从句的关系代词有：that, who, whom, whose, which; 关系副词有：when, where, why. 二、关系词的用法： （一）关系代词的用法： 1．作主语用who, which和that, 如： He is the man who/that lives next door. The train which/that has just left is for Shenzhen. 2．作宾语用whom, who, which, that, 如： The man (whom/who/that) we have just seen is a famous writer. Where is the book (which/that) I bought last week? 注：在非正式文体中，用于指人的关系代词who whom, that 通常可以省略，但在正式文体中通常用whom, 不可省略；用于指物的关系代词which和that 在非正式文体中也通常省略，但在正式文体中一般不省略。 3．作定语用whose, 如： (a) He is the man whose car was stolen last week. (b) It was a meeting whose importance I did not realize at that time. 注：“whose +名词中心词”这一结构在定语从句中既能作主语（如上a句），又能作宾语（如上b句）。whose 的先行词常用来指人，但有时也可以用来指具体事物或抽象概念，这时可以与of which 结构互换，词序是：“名词+of which”，如： They came to a house whose back wall had broken down.. (= the back wall of which) He’s written a book the name of which I’ve completely forgotten. (= whose name) 4．作表语只用that ，它既可以指人，也可以指物，但时常省略。如： He is no longer the man that he used to be. This is no longer the dirty place (that) it used to be. （二）关系副词的用法： 1．when 指时间，在从句中作时间状语，它的先行词通常有：time, day, morning, night, week, year 等。如： I still remember the time when I first became a college student. Do you know the date when Lincoln was born? 注：when时常可以省略，特别是在某些句型和某些时间状语中。如： Each time he came, he did his best to help us. But help never stopped coming from the day she fell ill. 2．where指地点，在从句中作地点状语。它的先行词通常有：place, spot, street, house, room,
从句就相当于一个形容词， 而且从句前面一定有一个先行词， 从句必有缺少的成分（主语，宾语，状语）。 如果先行词在从句做主语，则用which / that / who(人) 如果先行词在从句做宾语，则用which/ that/ who(人) /whom(人)或者不填引导词 如果先行词在从句做状语，时间用when，地点用where。 定语从句及相关术语： 1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。 2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。 注：关系代词有主语.宾语之分。一般whom作为宾语。 4.定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用‘……的’表示。主要由形容词担任。此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任．单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。 先行词：被限制或修饰的主句的主语。 （一）限定性定语从句 一、关系代词（在句中作主语、宾语或定语） 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在从句中作宾语也可以省略。[eg：this is the book （which）you want。]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，这些词包括当先行词是anything, everything, nothing , none等不定代词时，或者是由every, any, all, some, no, little, few, much等修饰时等，这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that 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. 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.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与of which 调换,表达的意思一样。 二、关系副词（在句中作状语） 关系副词=介词+关系代词 why=for which where=in/ at/ on/ ... which (介词同先行词搭配)

定语从句的基本用法 先请认真阅读下列各句，下列各句中的黑体部分均为该句所包含的定语从句： 1.This is the teacher who played basketball with us yesterday. 2.Tom is the boy whom they are looking for. 3.The house , which they built last year looks very new. 4.Physics is the most interesting subject that we learnt in the middle school. 从以上各句中我们可以看出定语从句是用来修饰它前面的名词或代词的，它起着修饰或限定作用。当然定语从句也可以用来修饰一个句子，在此我们不作讨论。定语从句分为限制性定语从句和非限制性定语从句。限制性定语从句所修饰的词是一个、一些或一类特定的人或事物，一般不能省略，拿掉后剩下的部分则没有意义，或者表述不清。非限制性定语从句则不然，它只对所修饰的词作进一步的说明，拿掉以后剩下的部分仍然可以成立，常常用逗号将其隔开。例如： This is the place where the Chinese Communist Party was founded. 此句中的定语从句是限制性定语从句。如果拿掉则This is the place.一句没有意义。 This message was left by Xiao Wang, who telephoned you just now. 此句中的定语从句是非限制性定语从句。如果拿掉则This message was left by Xiao Wang,一句仍有意义。 被定语从句修饰的词叫做先行词，引导定语从句的词称为关系代词或关系副词。常见的关系代词和关系副词有who, whom,that,whose,which,where,when,why等。现在我们侧重讨论如何使用这些关系代词和关系副词。如果关系代词在从句中作主语时一般不能省略，而作宾语时一般可以省略。 一，关系代词who, whom的用法。 1.who可以代替人（即它的先行词必须表示人），在从句中可以担任主语。也可以在 从句中担任宾语，但是它的前面不能带介词，如果带介词则必须使用宾格whom。 whom在从句中只能担任宾语。例如： a)This is the teacher who often tells us interesting stories in class. b)Mary is the girl who/whom Tom wants to marry. c)Mrs White is a teacher whom every student likes. d)She is the girl with whom I will go to Shanghai tomorrow. 2.在定语从句中当先行词表示人时who和that是通用的。例如： a)Miss Green is the new teacher who/that teaches us spoken English. b)John’s father is an engineer who/that came to see him last Wednesday. 但在下列情况下则宜用who 而不用that。
一、状语从句分类及常用连词： 类别连词 状语从句when, whenever, while, as, before, after, since, till, once, as soon as,etc. 状语从句where,wherever 状语从句because, since, as, for, now that, etc. 状语从句so…that, so that, such…that, that, etc. 状语从句in order that, so that, that, etc. 状语从句if, unless, as(so)long as, etc. 状语从句though, although, even if, even though, however, whatever, as,etc. 状语从句as…as, so…as, than, etc. 状语从句as, as if, as though, etc. 二、相似连词的用法区别 1.when, while, as, while表时间，从句需用延续性动词，切不可用瞬间动词。 when表时间，从句既可以用延续性动词，又可以用瞬间动词。 as表时间，与when相似，但侧重强调主从句动作同点或同段进行。 when, while后可以接分词短语。 2.because, as, since, for 语气位置意义 because最强前或后“原因”；表客观因果关系；回答“”as较强前“由于”；把众人所知的事实当作理由since较弱前“既然”；就对方陈述的事实作为理由for最弱后“理由”；对某一事实进行推断的理由 注：上面所说的“前”，指从句在主句之前；“后”，指从句在主句之后。 3.so that, so…that, such…that so that“以便”、“结果”表目的和结果。注意：在从句中有情态动词表目的。无情态动词表结果。 so…that “如此的…以致于”表结果。该结构常见于： 1.so+形／副＋that 2.so+形＋a(an)＋单数名词＋that 3.so＋manymuch＋复数名词（不可数名词）+that such…that“如此的…以致于”表结果。该结构常见于： 1.such＋a(an)＋形＋名词＋that 2.such＋形＋复数名词／不可数名词＋that
名词性从句的概念以及四类引导词的用法 一、名词性从句的概念 名词性从句，即指具有名词性质的从句，它包括主语从句、宾语从句、表语从句和同位语从句。名词性从句是英语学习中的一个语法重点，也是各类考试重点考查的内容之一。学习名词性从句主要应注意其引导词的用法与区别，从句的词序以及名词性从句与其他从句的区别等。从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。 二、名词性从句四类引导词的用法 1. 连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如： I hope (that) you enjoy your holiday. 希望你假期过得好。 That he likes you is very obvious. 很显然他喜欢你。 2. 连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。如： He asked whether [if] I would show him the way. 他问我是否可以给他带路。 Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句，不能用if 代替whether) 3. 连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。如： That’s why she w anted to leave. 这就是她想离开的原因。 When we arrive doesn't matter. 什么时候到没有关系。 Tell me which one you like best. 告诉我你最喜欢哪一个。 4. 连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。如： The question is how we should carry out the plan. 问题是怎样执行这个计划。 When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。

实用标准文案 状语从句 在复合句中作状语的从句叫状语从句。状语从句有时间、地点、原因、目的、结 果、条件、方式、比较、让步等种类。 一、时间状语从句 引导时间状语从句的连接词有: when, as, while, after, before, since, ever since, as soon as, once, till,until, whenever, no sooner than,hardly/scarcely...when, the moment/minute/instant/second,every time, each time, any time, the first time, next time, last time, all the time, by the time, directly, immediately, instantly 等。 1.表示“一···就···”的句型 1) as soon as/once As soon as he arrives, I'll call you.他一到，我就给你打电话。（as soon as侧重时间或动作先后衔接紧，而once 侧重条件，表示“一旦 ...”） 2) on doing sth/on one's + n.作时间状语 On arriving at the station, the thief was arrested. 一到达车站，这个小偷就被逮捕了。 On his arrival in Paris, he was recognized as a noble and thrown into prison. 他一到达巴黎，就被认出是一个贵族，并被投入监狱。 3)no sooner ...than , hardly/scarcely...when 它们表“一就”。结构中的否定词放在句首时，主句要倒装。（主句都用过去完成时， 从句用一般过去时。） No sooner had he reached home than it began to rain. 他刚到家，天就开始下雨了。 Hardly/Scarcely had I entered the room when the phone rang. 我一进屋，电话就响了。 注意当 no sooner, hardly, scarcely不放在句首时，主句不倒装，如： I had no sooner reached the bus stop than the bus started. 我刚到车站，车就开走了。 I had scarcely（hardly）entered the room when the phone rang. 4） the moment, the instant, the minute, the second The moment I saw him, I recognized him. 我一看见他，就认出了他。 We'll leave the minute you are ready. 你一准备好，我们就出发。 5) 有些副词如： instantly, immediately, directly可用作连词，后接从句。I left immediately the clock struck 5. 我刚走，钟就敲了五点。 2. when, while, as引导时间状语从句
A good student A developing country A developed country A 5-star friend A man named Chuck A language widely used 定语从句：修饰某一名词或代词的主谓结构(完整的基本句子结构-----五种句型)。 ↓↓ （主句之中）先行词关系词+其它成分 ↓ 在定语从句中必须担当一个成分。 ↓ 定语从句中缺啥就补啥 定语从句(The Attributive Clause) ( (二)关系代词的作用 1. 关系代词：用来连接定语从句，并在从句中代表先行词的代词。 先行词是物：which that 先行词是人：who that ※由who, whom, whose引导的定语从句。这类定语从句中who用作主语，whom作宾语，whose作定语。 e.g. This is the man who helped me. The doctor (whom) you are looking for is in the room. Do you know the man whose name is Wang Yu? ※在定语从句中，若先行词指人，其关系代词可用who, whom, 也可用that。 e.g. The girl who/that is speaking at the meeting is our monitor. The boy (who/whom/that) you saw just now is my brother. 3. 关系代词的具体用法及作用 1).who指人，在从句中做主语。 如：The boys who are playing football are from Class One. Yesterday I helped an old man who lost his way. 2). whom指人，在定语从句中充当宾语，常可省略。 如：Mr. Liu is the person (whom) you talked about on the bus. Mr. Ling is just the boy whom I want to see. 注意：关系代词whom在口语和非正式语体中常用who代替，可省略。 如：The man who/whom you met just now is my friend. 3). which指物，在定语从句中做主语或宾语，做宾语时可省略
名词性从句的连接词选用 名词性从句包括主语从句，表语从句，宾语从句和同位语从句引导同位语从句的词通有连词that，whether，连接副词how,when,where 等。（注：if 不能引导同位语从句。）。在各种考试中，其最主要的考查内容为连接词的选用。名词性从句的连接词可细分为以下四种：（1）以that来引导从句；（2）以whether/if引导从句；（3）以特殊疑问词引导从句；（4）以关系代词/副词引导从句。 一、以that引导从句 当从句的意思已完整时，名词性从句用that引导，that在从句中不作任何句子成分，仅起连接作用。如： It is certain that he will do well in his new job. （主语从句） Do you know that he has been admitted to Beijing University? （宾语从句） My decision is that we are to start at 6 tomorrow morning. （表语从句）The news that our team had won the game excited everybody. （同位语从句） 当用that引导从句时，需注意以下情况： 1．在主语从句中，that一般不可省略，尤其是当主语从句位于句首时，它绝对不可省略。如： That our team had won the game was good news to us. 2．在宾语从句中，that可省略。但当句中有两个并列的宾语从句时，
引导第二个宾语从句的that不可省略。如： Everybody knows (that) the earth goes round the sun. Everyone knew what happened and that she was worried. 3．当句子是以it作形式宾语时，引导宾语从句的that不可省略。如：He has made it clear that he will not give in. 4．that一般不能引导介词的宾语从句，偶尔可在except, but, besides 和in（在于…；在…方面）的后面引导宾语从句，that不可省略。如：Your homework is quite good except that you have made two small mistakes. The reason lies in that she works harder than the others do. He differed from other people in that he always looked farther ahead in his work. 在其它介词后面需要用that引导宾语从句时，必须用it作形式宾语。如： You may depend on it that I shall always help you. 5．在表语从句和同位语从句中，that不可省略。如： My advice is that you must give up smoking right now. The fact that he is a thief shocked all of us. 二、以whether/if引导从句 引导名词性从句的whether/if意为“是否”。在使用时，要注意两者存在以下区别。 1．在主语从句中，whether既可引导位于句首的主语从句，也可引导
简单地说，英语复合句所涉及的三大从句为：名词性从句（包括主语从句、宾语从句、表语从句、同位语从句），形容词性从句（即定语从句），副词性从句（即状语从句）。 1. 引导名词性从句通常有三类词：一类是连接词that, whether, if；另一类是连接代词who, whom, whose, what, which 以及whoever, whomever, whoseever, whatever,whichever；还有一类是连接副词how, when, where, why。 2. 引导形容词性从句（即定语从句）通常有两类词：一类是关系代词that, which, who, whom, as, whose等；另一类是关系副词where, when, why。 3. 引导副词性从句（即状语从句）的叫从属连词。不同作用的状语从句通常由不同的从属连词来引导。如： (1) 引导时间状语从句的从属连词主要有when, while, as, whenever, before, after, since, until, till, as soon as, the moment, the minute, the second, the instant, immediately, directly, instantly, once等。 (2) 引导条件状语从句的从属连词主要有if, unless, as [so] long as, in case 等。 (3) 引导目的状语从句的从属连词主要有in order that, so that, in case, for fear等。 (4) 引导结果状语从句的从属连词主要有so that, so…that, such…that等。 (5) 引导原因状语从句的从属连词主要有because, as, since, seeing (that), now (that), considering (that) 等。 (6) 引导让步状语从句的从属连词主要有although, though, even though, even if, while, however, whatever, whoever, whenever, wherever等。 (7) 引导方式状语从句的从属连词主要有as, like, as if, as though, the way等。 (8) 引导地点状语从句的从属连词主要有where, wherever, everywhere等。 (9) 引导比较状语从句的从属连词主要有than和as…as。
