A. 初中英语语法得注重些什么重点是……
英语中的复合句往往是学生学习的难点，因为句式复杂多变，而且主谓宾、定状补等句子成分运用到具体的句子中需要一定的语法知识作为基础，所以，一些学生以看到这些复杂的句式就会一个头变两个大。复合句(Complex Sentence)由一个主句(Principal Clause)和一个或一个以上的从句(Subordinate Clause)构成。下面我们就一起来看看复合句的有关语法知识。
主句是全句的主体，通常可以独立存在;从句则是一个句子成分，不能独立存在。
从句不能单独成句，但它也有主语部分和谓语部分，就像一个句子一样。所不同在于，从句须由一个关联词(connective)引导。
1、名词性从句
在句子中起名词作用的句子叫名词性从句 (Noun Clauses)。 名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
1)主语从句
作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如：
What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。
有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下：
(1) It + be + 名词 + that从句
(2)It + be + 形容词 + that从句
(3)It + be + 动词的过去分词 + that从句
(4)It + 不及物动词 + that 从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：
It is necessary (important, natural, strange, etc.) that …
It is suggested (requested, proposed, desired, etc.) that…
2)宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。
1. 由连接词that引导的宾语从句
由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如：
He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
注意：在demand、order、suggest、decide、insist, desire, request, command, doubt等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“(should)+ 动词原形”。例如：
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。
2. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。例如：
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。
She will give whoever needs help a warm support. 凡需要帮助的人，她都会给予热情的支持。
3. 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：
a. 引导主语从句并在句首时;b. 引导表语从句时;c . 引导从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。例如：
Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。
The question is whether she should have a low opinion of the test?现在的问题是她是否应该有一个低意见的测试?
Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。
I wonder whether he will come or not. 我想知道他来还是不来。
Can you tell me whether to go or to stay? 你能否告诉我是去还是留?
4. 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用
不同时态。例如：
he studies English every day. (从句用一般现在时)
he studied English last term. (从句用一般过去时)
I know (that) he will study English next year. (从句用一般将来时)
he has studied English since 1998. (从句用现在完成时)
当主句动词是过去时态(could, would除外)，从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等;当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：
The teacher told us that Tom had left us for America.
5. think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如：
We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so. 我相信他不会这样做。
3)表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。例如：
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That’s just what I want. 这正是我想要的。
This is where our problem lies. 这就是我们的问题所在。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如：
The reason why he was late was that he missed the train by one minute this morning .
【注意】whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句。
4)同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：
The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略; that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here.(that引导同位语从句，不能省略)
Have you got the idea(that)this book gives you of life in ancient Greece?(that引导定语从句，作宾语，可以省略)
5)名词性that-从句
1)由从属连词that引导的从句叫做名词性that-从句。That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语，例如：
主语：That she is still alive is her luck.他还活着全靠运气。
宾语：John said that he was leaving for London on Wednesday.约翰说他星期三要到伦敦去。
表语：The fact is that he has not been seen recently.事实是近来谁也没有见过他。
同位语：The fact that he has not been seen recently disturbs everyone in his office.
近来谁也没有见过他，这一事实令办公室所有的人不安。
形容词宾语：I am glad that you are satisfied with your job.
你对工作满意我感到很高兴。
2)That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：
It is quite clear that the whole project is doomed to failure.很清楚，整个计划注定要失败。
It's a pity that you should have to leave.你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be +形容词+ that-从句
It is necessary that…有必要……
It is important that…重要的是……
It is obvious that…很明显……
b. It + be + -ed 分词+ that-从句
It is believed that…人们相信……
It is known to all that…众所周知……
It has been decided that…已决定……
c. It + be +名词+ that-从句
It is common knowledge that………是常识
It is a surprise that…令人惊奇的是……
It is a fact that…事实是……
d. It +不及物动词+ that-从句
It appears that…似乎……
It happens that…碰巧……
It occurred to me that…我突然想起……
6)名词性wh-从句
1)由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：
主语： How the book will sell depends on its author.书销售如何取决于作者本人。
直接宾语：In one's own home one can do what one likes.在自己家里可以随心所欲。
间接宾语：The club will give whoever wins a prize.
俱乐部将给得胜者设奖。
表语： My question is who will take over president of the Foundation.我的问题是谁将接任该基金会主席职位。
宾语补足语：She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。
同位语：I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语：I'm not sure why she refused their invitation.我尚不能肯定她为什么拒绝他们的邀请。
介词宾语：That depends on where we shall go.
那取决于我们去哪儿。
2)Wh-从句作主语也常用先行词it做形式主语，而将wh-从句置于句末，例如：
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married.他们何时结婚依然不明。
7)if, whether引导的名词从句
1)yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的，因此也分别被称为yes-no型疑问句从句和选择型疑问从句，其功能和wh-从句的功能相同， 例如：
主语：Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。
宾语：Let us know whether / if you can finish the article before Friday.请让我们知道你是否能在星期五以前把文章写完。
表语：The point is whether we should lend him the money.问题在于我们是否应该借钱给他。
同位语：They are investigating the question whether the man is trustworthy.他们调查他是否值得信赖。
形容词宾语： She's doubtful whether we shall be able to come.她怀疑我们是否能够前来。
介词宾语： I worry about whether he can pass through the crisis of his illness.我担心他是否能度过疾病的危险期。
2)选择性疑问从句
选择性疑问从句由关联词if/whether…or或whether…or not构成，例如：
Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。
if和whether的区别：
1、 在动词不定式之前只能用whether 。如：
例8 I can’t decide whether to stay. 我不能决定是否留下。
2、 在whether …… or not 的固定搭配中。如：
例9 I want to know whether it’s good news or not . 我想知道是否是好消息。
3 、在介词后，只能用whether。如：
例10 His father is worried about whether he lose his work . 他的父亲担心是否会失去工作。
4、宾语从句放在句首表示强调时，只能用whether 。如：
Whether this is true or not, I really don’t know. 这是否真的，我真的不知道。
(例11 Whether they can finish the work on time is still a problem . 他们是否能准时完成这项工作还是个问题。--此例为主语从句，有误，感谢指出)
5、用if会引起歧义时，只用whether。如：
例12 Could you tell me if you know the answer ?
这句话有两种意思：“你能告诉我是否知道答案吗?”或“如果你知道答案，请告诉我，好吗?”。如用whether可避免歧义。
2、定语从句
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。
3.、状语从句
状语从句 (Adverbial Clause) 状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。
B. 谁能告诉我初中英语语法中,各种(宾语,主语,定语）从句的用法
第一,有心情的话啃啃语法书.
第二,没心情的话可以考虑听我贫下.
听着从句感觉好高深的样子,其实也就那么回事,他们的用法没什么特别要记得,一个是要用陈述语序（就是主谓宾不许倒置）,另一个就是要选准引导词.
一般我认为,宾语从句和主语从句是一类,统称为名词性从句,其用法除了以上所说两点以外,用法和地位基本就和名词没什么区别了,名词该怎么用,他就怎么用.
而宾语从句我一般认为是形容词性从句,同上所述,其除了遵守以上两条以外,用法和地位基本与形容词一样,不过我这个特殊的形容词一般是要放在被修饰词的后面,就是这样了.
还有一点,从句的时态要和主句一致.
示例：
主语从句：
what he needs is more time.
（引导词） （从句内容）
\ /
（主语从句） （主句的谓语和宾语）
他所需要的是更多的时间.
宾语从句（最简单的）：
everyone hoped that he would get well soon.
（引导词） （宾语从句内容）
\ /
（主语） （谓语） (宾语从句)
大家都希望他早日康复.
定语从句(不用怀疑,这是最难的)：
i won't take anything that does not biling to me
（主语） （谓语） （宾语） （宾语从句）
我不会拿走不属于我的东西.
要说基本的就这些了,如果还想再学的详细一点,最好找本权威的语法书看一看,那上面的更详细.
C. 初中英语语法问题
不需要的。
主句是你想描述的事物，定语是描述名词或代词的从句，与你想描述的名词或代词有关。
比如说你想说这样一个句子：
这是个即将获奖的演员。
This is an actor who will be awarded.
这里描述的演员即将获奖。主句是你正在叙述的时态，为一般现在，而这个演员本身是将来时。
如果你想说这样一个句子：
这是个曾经获奖的演员。
This is an actor who was awarded.
理由相似。
主句是跟你叙述的主语时态有关的。比如说你想描述个过去发生的事情。
The police,who was very helpful,had a TV show yesterday.
不过这个时候就要注意到所描述的对象也是过去的。
如果是描述真理，当然只能用一般现在，无论主句的事态如何。
比如：
The teacher told me that the moon,which does a circle around the earth,reflacts the light of the sun.
总之，从句只跟描述对象有关，主句只跟你说话的时态有关。
唉，我也不知道有没有把你讲懂，如果还是不会就直接来问我吧= =
D. 分享一下初中英语语法知识。语法全一点，有例子。章节清晰。

E. 请问英语语法中的关联词的具体用法有谁知道谢谢
关联词是历年高考所关注的热点，尤其那些既有区别又有联系的连词更是倍受命题者所青睐一、that,what 1.两者都可引导名词性从句。1)that本身无词义，常引导名词性从句，此时的从句意义已完整，常不省略(宾语从句除外)。It worried her a bit that her hair was turning gray.(it为形式主语) 2)what引导名词性从句时，在从句中常作主语或宾语。如：2.what一般不可引导定语从句，不能用作强调词；而that既可引导定语从句(由其前的先行词确定)，又可作强调词。如：All that is needed is a supply of rice. It was only when I reread the article lastnight that I realized the extended meaning. 3.what可作为感叹词引导感叹句，而that不可。如：What a long way it is from Beijing to Lon-don! 二、whether ,if 1.两者都能引导名词性从句之异同：1)当引导一个没有疑问词的问句时，两者均可。如：I'm not sure whether(if)I'll have time. 2)当提出两种选择时要用whether。如：Let me know whether you can come or not. 3)whether可用在介词后，if则不可。如：I haven't settled the question of whether I'll go back home. 4)whether可与不定式连用，if则不行。如：She doesn't know whether to get married now or wait. 5)引导主语从句时，if不能放句首，whether在句首、句中均可。如：It is doubtful if(whether)he is coming. 2.if还可以引起条件状语从句，whether不可以。如：If we try hard,we'll be able to complete the task in time. 3.whether...or(无论)，引起让步状语从句，if不可。如：Whether you come or not,I'll set off on time. 三、in case，if 两者都引导条件状语从句。1)in case作"如果"意义时，常放在句前，可与if替换。如：In case(If)he comes,let me know. 2)in case作"免得，以防"意义时常放在主句后，不能用if替换。试比较：You should insure your house in case there's a fire. John may call tonight.I don't want to go out in case he phones. I don't think I'll need any small change but I'll bring some in case. You should call 999if there's a fire. 四、though,although,as 这三个词都有转折之意，表示"虽然"、"尽管"。1.though和although引导让步状语从句时，常可互换，只是although的语气较强些，其主句前可用副词yet,still,nevertheless修饰，也可不用。如：Though／Although it was late,the farmer kept on harvesting the crops by the lights of the tractors. Though he was old,(yet)he worked hard. 2.though作连词时，可以用于省略句，引起让步状语从句可以用部分倒装语序；作副词时表"可是"、"然而"，常放于句末，但上述用法不适用于although。如：I've a bit of cold.It's nothing serious,though. 3.as引导让步状语从句时，从句用倒装语序，将表语、状语等置于句首，可与though互换。Poor though /as I am，I can afford it. 五、however /whatever...,no matter how/what... 1.no matter what /how等只能引导以形容词或副词为中心的让步状语从句，且用部分倒装形式。如：However /No matter how hard it may be，I must try. 2.however无论怎样，whatever无论什么，既可引导让步状语从句也可引导名词性从句，要视具体情况而定。如：These wild flowers are so special that I would do whatever I can to save them. However late he is,Mother will wait for him to have dinner together. We will have to finish the job,however long it takes. 六、even if,even though "即使"、"纵使"都可引导让步状语从句，但even if更强调假定性。如：Even if he is poor,she loves him.＝He may be poor,yet she loves him. Even though he is poor,she loves him.＝He is poor,yet she loves him. Even though /if I didn't know anybody,Ihad a good time. 七、when,while 二者都可以引导时间状语从句，当从句的动词是延续性动词时，两者可互换。如：He entered the room while(when)his mother was talking with his headteacher. 1.若要表示转折的对比，用while，意为"而，然而"。如：She thought I was talking about her uncle,while in fact,I was talking about my uncle. 2.when相当于"and then"或"at the time that"也是常见考点，主句为特定时间，常用过去进行时或be about to do(即将发生)表达，从句表达的多是偶然性的动作。八、unless(除非，如果不)，if...not 两者都引导条件状语从句。如：He is sure to come unless he has some urgent business. ＝He is sure to come if he hasn't any urgent business. The men will have to wait all day unless the doctor works faster. 1.当从句是虚拟形式时，只用if...not,不用unless引导。如：The flowers would have died,if you had not watered diligently. 2.当主句为疑问句时，不用unless,而用if...not。如：What shall we do if he doesn't reply to our letter? 3.当unless引导的从句带有否定词时，不能用if...not代替。如：I'll go unless no one else goes. 九、till,until(直到……，直到……才) 1.都可引导时间状语从句，当从句在主句后面时，二者均可用；主句谓语动词为延续性动词，用肯定式；若是短暂性动词，用否定式。如：Sandy had left his keys in the office so he had to wait until /till his wife came back. They watched the train until /till it disappeared in the distance. I didn't leave until /till he came back. 2.但是在句首或强调句中时，一般用until而不用till；在句首时，主句谓语要部分倒装而从句不倒装。如：Not until all the fish died in the river did the farmers realize how serious the pollution was! 十、in order that,so that,so...that 1.前两者都可以引导目的状语从句，从句中通常要有can /could,m ay /might,will /would等情态动词，而且，当从句的主语与主句的主语一致时从句可转化为in order to do sth.／so as to do sth.／to do sth.。如：John shut everybody out of the kitchen so that he could prepare his grand surprise for the party. They set off for the station very early in order that /so that they might not miss the first bus.

G. 初中英语语法从句有哪些
主要是宾语从句和状语从句，如果说考的稍微难一些的话就是定语从句以及名词性从句，一般考的话后两者的难度不会很大。
宾语从句在句中作及物动词或介词的宾语，从句放在主句之后，前后不用逗号分开。
宾语从句：
引导宾语从句的词有：
连词that(在口语中that常可省略)，if, whether,如：
He knows that Jim will work hard.
连接代词who, whom, which等，如：
Do you know who (whom) they are waiting for?
连接副词when, where, how, why等，如：Could you tell me how we can get to the station?
3.whether和if都有“是否”的意思，一般情况下两者可以换用，但在介词之后，
不定式之前，与or not连用，在句首或在引导表语从句，同位语从句时，只能用whether,如：I want to know if/whether the news is true. He doesn't know whether to stay or not?
4.宾语从句要用陈述句语序。
5.宾语从句一定要注意时态呼应，即：当主句谓语动词是过去式时，从句中谓语动
词也要用过去范畴的时态，但若从句陈述的是真理或客观规律，其谓语的时态仍用一般现在时，如：
He asked who could answer the question.
My father told me that the earth goes around the sun.
6.一个宾语从句只能用一个连词。
7.当主句谓语动词是think, believe等动词时，宾语从句的否定意义要放到主句中。另外，当主句主语为第一人称时，后面若接附加疑问句，那么附加疑问句的主语、谓语应与从句中的主谓语保持一致。如：
I don't think he looks like his father, does he?
8.直接引语和间接引语也是宾语从句，直接引语是引述别人的原话，放在引号内，
不用连词联接；间接引语是用自己的话转述别人的话，通常用连接词与主句联接。
(1)陈述句变为以that引导的宾语从句，如：
He said,“I'm happy.”[FY()[FY]]He said that he was happy.
(2)一般疑问句变为if(whether)引导的宾语从句，如：
He asked me,“Does his father know Mr Green?”
---He asked me if his father knew Mr Green.
(3)特殊疑问句变为由who, what, where, how等疑问词(连接代词或连接副词)引导的宾语从句，如：
He asked me,“Where is Mr Wang?”
---He asked me where Mr Wang was.
注意上述例句中连词、时态、语序等变化。
