(word完整版)英语三大从句知识,文档
英语三大从句主语从句用作主语，如：：That the earth is round is true.地球为圆的是真实的。
宾语从句用作宾语。
如：Do you know where he lives?表语从句用作表语，如：My opinion is that you should not go alone.我的建议是你不应单独前往。
同位语从句用于讲解说明前面的名词。
如：The fact that the earth is round is true.地球是圆的的事实是真实的。
〔that从句用于讲解说明the fact〕定语从句相当于一个形容词，用于修饰前面的名词。
如：The student who answered the question was John. 答复以下问题的学生是John.状语从句相当于一个副词，如：When it rains, I usually go to school by bus. 天下雨时，我平时坐公共汽车上学。
〔时间状语〕If he comes tomorrow, you will see him. 若是他明天来，你就可以看见他。
〔 if 引导的条件状语从句，其结构为： if + 状语从句，＋主句〕。
要注意在状语从句中有一个规那么是“主将从现〞，即主句是将来时，那么从句要用一般现在时表示将来。
主句和从句的划分方法是同样的。
句子的成分从谓语动词处来划分比较简单。
谓语动词前面的局部是主语，后边常接宾语，修饰谓语动词的是状语，修饰主语、宾语的是定语，假设谓语是系动词，那么系动词后的局部是表语。
如：I am a teacher. 其中， I 是主语， am 是谓语， a teacher 是表语。
He likes playing football very mucy.其中， he 是主语， likes 是谓语， playing football 是宾语，very much 是状语。

高考英语三大从句复习一、专题详解一、名词性从句解题技巧1.正确分析句子成分是做对题的关键。
2.连接词的特点：that 没有意义，在从句中只起连接作用，不充当句子成分；whether, if 表“是否”，在从句中只起连接作用，不充当句子成分；what, which, how, where, when, whatever 等，有各自的意义，在从句中担任成分。
3.that 引导主语、表语、同位语从句时不省略；有多个that 引导的宾语从句时，只有第一个that 可省略；引导的宾语从句中含有从句时，也不省略。
4.介词后一般不接that 引导的宾语从句，此时需要用it 作形式宾语；某些动词enjoy, hate, have, like, love, appreciate, take 也不能接that 引导的宾语从句，此时需要用it 作形式宾语。
如：You may rely on it that he will come on time. 5. reason 做主语时，表语从句只能用that 引导。
6.d oubt 在肯定句中其后的宾语从句常用whether, if 引导；doubt 在否定和疑问句中其后的宾语从句常用that 引导。
如：There is some doubt whether he will come tomorrow.7.与if 相比较，whether 引导所有名词性从句，也可用于连接介词后的宾语从句，可以discuss, decide 后引导宾语从句，还可与or not 连用。

英语 三大从句
英语三大从句三大从句包括名词性从句、形容词性从句和副词性从句。
名词性从句 (Noun Clause)：英文：A noun clause is a type of dependent clause that functions as a noun within a sentence. It can act as the subject, object, or complement of the main clause.中文：名词性从句是一种在句子中起名词作用的从属从句。
它可以充当主句的主语、宾语或补语。
形容词性从句 (Adjective Clause)：英文：An adjective clause is a dependent clause that describes or gives more information about a noun in the main clause. It usually begins with a relative pronoun (such as who, which, that) or a relative adverb (such as when, where, why).中文：形容词性从句是一个描述或提供更多信息关于主句中名词的从属从句。
它通常以关系代词（如who, which, that）或关系副词（如when, where, why）开头。
副词性从句 (Adverbial Clause)：英文：An adverbial clause is a dependent clause that functions as an adverb in the sentence. It provides information about the time, place, manner, reason, orcondition of the action in the main clause.中文：副词性从句是一个在句子中起副词作用的从属从句。

中考英语三大从句知识点总结.doc
中考英语三大从句知识点总结精品｜初中三大从句总结：定语从句精讲，必须收藏！定义在主句中做宾语的从句叫做宾语从句。
(简单来讲，就是用一个句子充当了另一个句子的宾语)如：She knew that the teacher had seen the film.“that the teacher had seen the film”做knew 的宾语，同时又是由连接词that 引导的从句，所以它叫做宾语从句。
分类1.动词宾语从句：顾名思义，它是位于动词后面的宾语从句。
He asked whose handwriting was the best in our class.他问我们班上谁的书法。
2.介词宾语从句：顾名思义，它是位于介词后面的宾语从句。
I agree with what you said just now.我同意你刚才说的话。
3.形容词宾语从句：顾名思义，它是位于形容词后面的宾语从句。
I am afraid that I will be late.恐怕我要迟到了。
语序无论主句是陈述句还是疑问句，宾语从句都必须使用陈述语序，即“主句+连词+宾语从句(主语+谓语+……)”句式。
根据连接词在从句中所担任的不同成分，可分为以下四种：1)连接词+谓语。
连接词在从句中作主语。
常见的连接词有：who，what，which等。
Could you tell me who knows the answer，please?你能告诉我谁知道答案吗?The small children don't know what is in their stockings.这些小孩子不知道袜子里有什么东西?2)连接词+名词+谓语。
连接词在从句中作主语的定语。
常见的连接词有：whose，what，which，how many，how much等。
He asked whose handwriting was the best in our class.他问我们班上谁的书法。

复合句【语法要点】复合句是由一个主句加一个或几个从句所构成的句子。
从句只用作句子的一个成分，不能独立。
根据从句在句子中的作用，可分为名词性从句、定语从句和状语从句三类。
（一）名词性从句名词性从句包括主语从句、表语从句、宾语从句、同位语从句。
其关联词有连接词that、if、whether；疑问代词who、what、which和疑问副词when、where、how、why等。
1.名词性从句句法结构：从属连词that whether 主语从句That he will come is certain.（that不可省）Whether she is coming or not doesn’t matter too much.（不能用if）宾语从句I think（that）he will be all right in a few days.I went in and asked if（=whether）they had a cheap suit.I wonder whether（不能用if）it is true or not.表语从句The fact is（that）I have never been there.The question is whether（不能用if）it is worth doing.同位语从句The fact that she had not said anything surprised all of us.They asked me the question whether the work was worth doing.连接代词that who whom whose which 主语从句Who will help him is not known.What he said is very important.Which side will win is not clear.宾语从句（1）作及物动词的宾语。
例如：I really don’t know what he is doing.Do you know who/whom they are waiting for?He asked whose dictionary it was.He can’t tell which method they will use for the experiment.（2）作介词的宾语。
例如：Pay attention to what the teacher said.I wondered to whom he had given the letter.表语从句That is what he is worried about.The question is who will come here.The question is which team will win the match.连接副词where when why how 主语从句Where she has gone is not known yet.When they will start is not known yet.Why he did it wasn’t quite clear.How he became a great scientist is known to us all.宾语从句I don’t know where we are going to have the meeting.Please tell me when we shall discuss our work plan.Do you know why he said that?Will you tell me how I can get to the railway station? 表语从句That is where he was born.This is why he is late.This is how he did it.The question is when he will be back.同位语从句I have no idea when he will come back.You have no idea how worried I was.The problem is where we can get so much money.2.名词性从句的其它用法：1）if不能引导表语从句。
连接代词who、what、whose、which不能引导同位语从句。
2）有时as、as if/though、because也可以引导表语从句，能跟表语从句的谓语动词一般为系动词be、seem、look等。
例如：Things are not always as they seem to be.事情并不总是像表面上看来的那样。
It looks as if it were going to rain. It is because you eat too much.3）介词宾语不可以用which来引导，而要用what来引导。
例如：We can learn what we did not know. He will talk to us about what he saw in the U.S.4）连词that引导的名词性从句除能用在except、but、in后之外很少作介词的宾语，。
其它一些介词的宾语从句如果由连词that引导，则需用it先行一步作形式宾语。
例如：He is a good student except that he is careless.You may depend on it that they will support you.5）若主句谓语动词是及物动词make、find、think、see、hear等，则把宾语从句置于宾语补足语之后，用it作形式宾语。
例如：We find it necessary that we practise spoken-English every day.6）某些作表语的形容词或过去分词后常接宾语从句，如sure、happy、glad、certain、pleased、afraid、surprised、satisfied等，连词that可省略，有的语法书称之为状语从句。
例如：I am sure that he will succeed.I am afraid you don’t understand what I said.Mother was very pleased her daughter had passed the exams.7）连接代词whoever、whatever、whichever也可引导宾语从句。
例如：I will show you whatever you want to see.You may choose whoever you like. I will take whichever fits the sockets.（插座）8）同位语从句一般跟在某些表示抽象概念的名词后面，用以说明名词所表示的具体内容。
常跟同位语从句的名词主要有：idea、news、fact、promise、answer、belief、condition、doubt、fear、hope、order、problem、proof、question、reply、report、suggestion、thought、truth等。
由连词that引导同位语从句既无语法功能，也无词汇意义，只是引导词；由连词whether引导同位语从句无语法功能，但有词汇意义“是否”；由连词when、where、how引导同位语从句在句中分别作作时间、地点和方式状语。
注意→①关联词只能用whether不能用if表示“是否”的情况如下：A)在表语从句和同位语从句中。
例如：The question is whether the film is worth seeing.The news whether our team has won the match is unknown.B)在主语从句中，只有it作形式主语时whether和if均可。
否则，也只能用whether。
例如：Whether we shall attend the meeting hasn’t been decided yet.It hasn’t been decided whether/if we shall attend the meeting.C)在介词之后（介词往往可以省略）。
例如：It all depends (on) whether they will support us.D)后面直接跟动词不定式时。
例如：He doesn’t know whether to stay or not.E)与or not连用时。
例如：We didn’t know whether or not she was ready.②关联词if、whether均可使用的情况如下：A)引导宾语从句，但当宾语从句是否定句时，一般用if引导。
例如：I wonder if/whether the news is true or not. I don’t care if it doesn’t rain.B)在“be+形容词”之后。
例如：He was not sure whether/if it is right or wrong.③用if引导宾语从句如果会引起歧义，应避免使用if而用whether。
试比较：Please let me know if you want to go. Please let me know whether you want to go.（if从句既可理解为宾语从句，也可理解为条件状语从句）doubt作“怀疑”解接宾语从句时，主句为肯定句用whether或if，主句为否定句或疑问句用that。
10）it作形式主语①that所引导的主语从句常由代词it作形式主语。
且wh-系列引导词引导的从句均可。
例如：It makes everyone happy that the girl is still alive.It doesn’t matter too much whether he’s coming or not.It is still open to question who is to head the group. 谁领导这个小组还没定下来。
②常以it作形式主语的句型有：—It +be+形容词(obvious、true、natural、surprising、good、wonderful、funny、possible、likely、certain、probable)+that从句—It +be+名词词组(no wonder、an honour、a good thing、a pity、no surprise)+that从句—It +be+过去分词(said、reported、thought、expected、decided、announced、arranged)+that从句—It +seem、happen等不及物动词及短语+that从句—It +doesn’t matter(makes no difference, etc)+连接代词或连接副词引导的主语从句—当that引导的主语从句出现在疑问句中时，也要以it作形式主语，而把主语从句后置。
