高中英语从句综合讲解
高中英语从句综合讲解 Revised by BETTY on December 25,2020【宾语从句】在英语中，有简单句(只含一个谓语动词)、并列句(用连词连接，含不止一个谓语动词)和复合句(含从句)。
本节课我们复习复合句里面的宾语从句．．．．。
如：She knows that he will come back soon. I’m afraid that I can’t go to your party.1.宾语从句的【引导词】宾语从句的引导词分三种。
●(1) 如果从句是陈述句，引导词用that.（that在口语中常省略）主句：He says... 从句：He is tired of playing computer games.→ He says that he is tired of playing computer games.●(2) 如果从句是一般疑问句，引导词用if/whether，表示“是否”。
主句：I don’t know… 从句：Does Tom likes fish→ I don’t know if / whether Tom likes fish.【注意】① whether引导的从句常与or not连用，而if不能；② 宾语从句可简化为whether to do的搭配，而没有if to do这种搭配.如：Could you tell me whether I should finish my homework today or not Could you tell me whether to finish my homework today【拓展】if有两个意思：1. 表示“是否”，引导的是宾语从句。
动词的时态视情况而定。
2. 表示“如果”，引导的是条件状语从句，时态用一般现在时表示将来（遵循“主将从现”规则）。
经典例题：--Do you know if Tom ____________(go) hiking with us--I’m not sure. But i f he ____________(go), I will take many photos with him .●(3) 如果从句是特殊疑问句，直接用该疑问词来引导。
高中英语定语从句详细讲解
高中英语定语从句详细讲解定语从句基本概念在复合句中，修饰名词或代词的从句叫定语从句。
引导定语从句的词叫关系词。
被修饰的名词或代词叫先行词。
定语从句一般放在先行词的后面。
2 定语从句的关系词引导定语从句的关系词有关系代词和关系副词。
常见的关系代词包括that ，which ，who （宾格whom，所有格whose ），as 等。
关系副词包括where ，when ，why 等。
关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。
3 定语从句的分类根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。
1. 限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去。
例如：Any man that / who has a sense of duty won' t do such a thing.任何有责任感的人都不会做这样的事。
2. 非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。
例如：The house,which we bought last month,is very nice. 这幢房子很漂亮, 是我们上个月买的.注意：非限定性定语从句中不能使用关系代词that 。
4 关系代词的用法that 既可以用于指人，也可以用于指物。
在定语从句中作主语、宾语或表语，作宾语可省略。
例如：Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。
（that 作主语）The coat （that ）I put on the desk is blue.我放在桌子上的那件外套是蓝色的。
（that 作宾语）which 用于指物，在句中作主语、宾语或表语，作宾语可省略。
例如：The building which stands near the train station is a supermarket. 位于火车站附近的那座大楼是一家超市。

高中英语表语从句的趣味讲解（图片版）
表语从句什么是表语？表语从句，紧跟着系动词的从句系动词表语I am happyMom looks angryDad seems tired其中，am,look,seem都是系动词。
而系动词后面的东西，就是表语。
换句话说，表语从句就是紧跟着系动词的从句。
6类系动词在正式讲表语从句以前，先简单盘点下常见的6类系动词：be动词am,is,are感官动词look,sound,taste,smell,feel持续系动词keep,stay,remain变化系动词get,become,grow,turn,go表象系动词appear,seem终止系动词prove,turn out表语从句3大类型01系动词+that02系动词+疑问词03系动词+特殊连接词that仅仅只是连接词，什么成分都不是。
在口语和非正式文体中，that有时是会省略的；很多语法讲解文章称“that 不能省略”，这个规定就太死了。
比如，系表语从句The fact is《that)I have no实际上，我啥也不知道。
系表语从句The reason is that she is a terrible原因就是她做的饭真的很难吃(■•)•••系表语从句The reality is that they have run out of money.现实情况是，他们花光了钱。
系表语从句The trouble was《hat Flash was too pok)麻烦就在于，闪电太特啼磨蹭了。
值得注意的是，如果整句的主语是要求、建议、命令等词,表语从句用“should +动词原形”；其中，should可以省略。
这类词常用的有:要建4叩request advice order requirement suggestion instructioninsistence proposalrecommendationideanotion系表语从句My idea is ghat people convicted of a sex crim；(should)undergo chemical castratio我认为，犯了性侵的渣渣应实行化学阉割。

2. 由各种疑问词 引导的宾从
【例1】I don’t think this dress fits you well. 【例2】I don’t believe you will finish the work today
注意： 这种否定前移的宾语从句， 在变成反义疑问句时， 反义疑问句要跟着从句走，否定要还原：
【例3】I don’t think (that) he is interested in that thing, is he?
2020/6/7

不共同点：when可用于非延续性动词和延续性(范围广)
while只用于延续性动词， 且有对比关系时。 AS 强调主句和从句的动作同时发生时, 译为“一边……一边……”，“随着时间推移”。
① Sorry, I was out when you called me．（call为短暂性动词）

超实用高考英语专题复习：专题6 从句(定语从句、名词性从句、状语从句)(复习思维导图+必备知识手册)
专题06 从句（定语从句、名词性从句、状语从句）距离高考还有一段时间，不少有经验的老师都会提醒考生，愈是临近高考，能否咬紧牙关、学会自我调节，态度是否主动积极，安排是否科学合理，能不能保持良好的心态、以饱满的情绪迎接挑战，其效果往往大不一样。
以下是本人从事10多年教学经验总结出的以下学习资料，希望可以帮助大家提高答题的正确率，希望对你有所帮助，有志者事竟成！养成良好的答题习惯，是决定高考英语成败的决定性因素之一。
做题前，要认真阅读题目要求、题干和选项，并对答案内容作出合理预测;答题时，切忌跟着感觉走，最好按照题目序号来做，不会的或存在疑问的，要做好标记，要善于发现，找到题目的题眼所在，规范答题，书写工整;答题完毕时，要认真检查，查漏补缺，纠正错误。
总之，在最后的复习阶段，学生们不要加大练习量。
在这个时候，学生要尽快找到适合自己的答题方式，最重要的是以平常心去面对考试。
英语最后的复习要树立信心，考试的时候遇到难题要想“别人也难”，遇到容易的则要想“细心审题”。
越到最后，考生越要回归基础，单词最好再梳理一遍，这样有利于提高阅读理解的效率。

考点1定语从句的种类(1)限制性定语从句从句在句中是不可缺少的部分，去掉后主句意思往往不明确，与主句之间不用逗号隔开。
This is the house which we bought last month.(2)非限制性定语从句从句是对主句或先行词的补充和说明，去掉后不影响主句的意思，与主句之间往往用逗号隔开。
The house, which we bought last month, is very nice.当先行词是专有名词或被物主代词/指示代词所修饰时，其后的定语从句通常是非限制性的。

Tips for Subject Clause
1.主语从句可直接位于主语的位置,如果从句较长,谓语又较短,可用it 作形式主语,而将从句放在句末。避免 “头重脚轻” ｛That he will refuse this piece of advice ｝is impossible.
逗号+关系代词which 引导 的句子，修饰整个主句。 构成非限制性定语从句
3.This is the computer (on which he spent all his savings ).
介词+ 关系代词which whose 引导的句子做 computer的定语

英语中六大从句用法总结1.主语从句1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。
常见的句型有：*It is a fact\a pity\a question\good news that...*It seems\appears\happened\has turned out that...*It is clear\important\likely\possible that...*It is said\reported\estimated\has been proved that...It is said that comic books create a connection between people of the same generation.It seems that the performance is very useful.2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
How the plan is to be carried out should be discussed again.I did know why I felt like crying.2.宾语从句1）宾语从句可位于及物动词、介词和某些形容词后。
连词that常可省略。
介词后一般接疑问词引导的宾语从句。
in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.*All this is different from what American young people would say about friendship.*He is certain that watching so much television is not good for children.*This article is well-written except that it is a bit too long.2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。
He didn't think that the money was well spent.3.表语从句表语从句出现在结构为“主语+系动词+表语从句”的句子中。
表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。
that常可省略。
如主句主语为reason,只能用that引导表语从句，不可用because.Perhaps the most important thing to remember is that there is no one common type of life in America.The reason why so many people died there is that there were not enough food supplies.It looks as if successful international cultural communication will make the world smaller.4.同位语从句同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。
常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。
She finally made the decision that she would join the fashion show.I had no idea how many books I could borrow at a time.The news came that their team had won the championship.5.定语从句定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。
定语从句通常位于先行词之后，由关系代词或关系副词引导。
*限制性定语从句限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。
引导定语从句的关系代词有who,whom,whose,which,that等。
who,whom,whose 用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。
关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.Those who live alone or who are sick may have trouble in getting close to other people.The girl whose parents died in an accident is living with her grandmother.1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。
That is all that I've heard from him.He's the first person that I'm going to interview this afternoon.2)关系代词的省略在从句中作宾语的关系代词常可省略。
关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。
This is one of those things with which we have to put up.This is one of those things (which\that) we have to put up with.3)引导定语从句的关系副词有when,where,why等。
关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.No one knows the reason why(=for which) he was so angry that day.5.定语从句*非限制性定语从句非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。
不可用that引导非限制性定语从句。
关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.*“介词+which\whom\whose”引导的定语从句“介词+which\whom\whose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。
This is the computer on which he spent all his savingsIt is written by a person with whom we are all familiar.*as引导的定语从句as引导的定语从句主要用于“such...as”及“the same...as”的结构中，代替先行词是人或物的名词。
as引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。
These are not such problems as can be easily solved.(as代替先行词problems)As is mentioned above,no single company or group can control what happens on the Internet.(as 代替主语)6.状语从句*时间状语从句引导时间状语从句的从属连词和词组有：1）when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。
