㈠ 初中英语语法大全
学英语一开始要学发音。英语是拼音文字，由字母组单字。英语字母共有二十六个，其中字母a、e、i、o、u是元音字母，其余二十一个是辅音字母，其中y字母有时当元音字母用。每个字母可以有一个或一个以上的读音，因此，英语语音共有五十个音位，音位的书写形式是音位字母，即音标符号，一个音位字母即音标，表示一个音位，所以，必须先学习五十个KK音标，然后根据发音规则拼读单字。下面是一些常用的发音规则。
一、辅音字母在单字中的发音一般是一对一的，如p-b、t-d、k（qu）、f-v、s-z、r、h、j、m、n、l、w就发它的本音，一般字母和音标写法一致，或者字母名称当中，包含了这个字母的音素。
二、有些辅音字母有多个发音。如：字母c后面接a，o，u的时候，c的发音与字母k发音相同，叫做“hard c sound”，当字母c后面接e，i，或y的时候，通常c的发音与字母s发音相同，叫做“soft c sound” 。有时在e或i前面，c会发/ʃ/音。字母g后面接a，o，u的时候，所发的音叫做“hard g sound” ，当字母g后面接e，i，或y的时候，有时g的发音与字母j的发音相同，叫做“软g音”。x在单词中间或结尾时发/ks/音，在单词中间时有时发/gz/音，在单词起始位置时发/z/音。y在单词起始位置时发音为辅音/j/，单词或音节中间或结尾时被当做元音，在重读开音节里发长元音/aɪ/，在重读闭音节里和词末发短元音/ɪ/。
三、辅音字母组合的发音也是有规律可循的。常见的辅音字母组合有：tr-dr，发音时舌身与r相似，舌尖贴上齿龈后部，气流冲破阻碍发出短促的t-d后立刻发r。ck只发一个k的音，ng的发音是舌头抵住上颚后方所发出的鼻音，n在k之前也这样发音。
四、复合字母构成的单音。digraph是两个（或三个）辅音字母在一起只发一个音，通常指以下四种组合：ch（tch），sh，wh和th。ch发/tʃ/音，sh发/ʃ/音，一般来说wh发/hw/音（清辅音），但在o前面发/h/音，th的发音则需要一些记忆力了，在虚词和一部分代词中发浊音（舌尖在上下牙齿中间，声带需要振动，声音从牙齿和舌头之间的缝隙里出来），其它以th开始的单词基本上都发清音（舌尖在上下牙齿中间，声音从牙齿和舌头之间的缝隙里出来，但是声带不振动）。
五、在有些辅音字母组合中，其中一个字母是不发音的，如kn中的k、ps中的p、mb和bt里的b、mn里的m、wr中的w。在罗曼语族词汇里，辅音字母h一般也不发音；而在法语词源的外来语里，辅音字母在词末也不发音，如depot、ballet、faux pas等。
六、英语里元音的发音比较复杂，每个元音都可以发多个音，掌握了元音的发音规律才能对整个单词的发音有比较准确的掌握。元音字母有五个：a，e，i，o，u，另外y在一个单词的中间或结尾时也被当做元音。每个单词里都包含有至少一个元音，元音是单词的“最强音”。元音所发的音取决于该元音在单词中的位置或它是如何与其它元音组合的。一般来说，如果五个元音字母中的任意一个后面紧接着一个或几个辅音字母，这个元音字母就处于重读闭音节中，发成短音：a发/æ/、e发/ɛ/、i和y都发/ɪ/音、o发/α/、u发/ʌ/音。
七、如果一个单词以字母e结尾，前面的元音发长音，叫做重读相对开音节（magic e）。如果一个元音是在一个单词或重读音节的结尾，该元音也发长音，叫做重读开音节，所谓长音就是元音字母的名字，如：a的长音为/e/，e的长音为/i/，i和y的长音都是/aɪ/，o的长音为/o/，u的长音为/ju/。重读相对开音节结尾的字母e只起到让前面的元音发长音的作用，自己是不发音的。
八、当一个单词或音节里有两个元音时，通常第一个元音发长音，第二个元音不发音，叫做vowel digraph。但是al、au、aw、ou、o有时发/ɔ/这个音，也是长元音。但是，在一些特殊情况下，元音后面紧接着辅音字母的时候，该元音是发长音的。如o在st、ld前，i在gh、gn、ld、nd前都要发长音，但元音字母o接st时有时也发成长元音/ɔ/，如cost，lost等。
九、双元音是两个元音音素组合在一起的，所以听上去有两个音，尽管这两个音并不是两个元音所单独发出的，如oi（oy）和ou（ow）分别发/ɔɪ/和/aʊ/音。
十、元音字母与r结合起来后，发卷舌音，如ar发/αr/、or发/ɔr/、er、ir、ur都发/ɝ/。
十一、五个元音字母在非重读音节中发弱元音/ə/。
学会了发音后，再开始学词汇和语法。英语属于印欧语系的日耳曼西部语支，英语的词汇有开放性，一部分是日耳曼语族词汇，一部分是罗曼语族词汇，还有一部分是从法语、德语、西班牙语、意大利语、拉丁语、希腊语、阿拉伯语以及其它语言引进的词汇。英语属于屈折语，但是它的屈折变化形式相对比较少，除了名词、代词、动词、形容词、副词有词形变化外，数词、冠词、介系词、连接词、感叹词都是不变的，只有简单句、并列句、复合句三种句子结构，词序比较固定。只要你用心学，一定能学好英语这门语言的，希望我能帮助到你。
㈡ 英语名词性从句的语法知识
你这个问题太宽泛。只能选择部分回答。
有时因意思表达的需要，要用一个从句在句子中作主语、宾语、表语或同位语，称为名词性从句（包括主语从句、宾语从句、表语从句和同位语从句）。名词性从句作为一个整体，本身在整个句子中起一个名词的作用；同时既是从句，就从句内来说，也有主、谓成份。当然，从句要有引导词。
引导词的基本含义及用法
对于引导词要注意两点：a. 本身所含的意思，b. 其在从句中所充当的句子成分。据此，可以分成几类（这是我自己的办法，要比别的办法管用）
①that
②whether/if, because, as if/though
③when, how, where, why, whenever, wherever, however
④what, which, who, whom, whatever, whichever, whoever, whomever
⑤what, whatever, which, whichever, whose
1．That 既无意义，也不在句子中担任成分。
可以说只是一个“标志”，标明所跟的是一个从句而已。
That theory must go hand in hand with practice is a principle we should always keep in mind.
2．Whether/if, because, as if 本身有意义，但在从句中不担任成分。
Whether/if --“是否”；because—“因为”；as if—“似乎”
She hesitated whether she should take our advice.
All this was over twenty years ago, but it’s as if it was only yesterday.
It is because you don’t have confidence.
3．When, where, why, how, whenever, wherever, however 本身有意义，且在从句中担任状语。
When--“。。。的时间”或“何时”；whenever—“无论何时”，作时间状语
Where—“。。。的地点”或“何地”；wherever—“无论何地”，作地点状语。
Why--“。。。的原因”或“为什么”，作原因状语。
How--“。。。的方式”或“怎样”；however—“无论怎样”，作方式状语。
When we shall have our sports meet is still a question.
This is where our basic interest lies.
I don’t know why he is absent.
How the prisoner escaped was a complete mystery.
4．What, which, who, whom, whatever, whichever, whoever, whomever本身有意义，且在从句中作主语、宾语、表语。
What—“。。。的（东西、事情。。。）”或“什么”，whatever—“无论什么”，在从句中作主语、宾语、表语。
Which—“哪一个/些”，whichever—“无论哪一个/些”，在从句中作主语、宾语、表语。
Who—“谁”，whoever—“无论谁”，在从句中作主语、表语，有时也可代whom，whomever作宾语。
Whom—“谁”，whomever“无论谁”（罕用），在从句中作宾语。
She is sorry for what she said. （她所说的话）（what无疑问含义）
I don’t know what will happen next. （将发生什么事）（what有疑问含义）
I don't know which of us was the more scared. （我们中的哪一个更害怕）
They never found out who the murderer was. （谋杀者是谁）
He asked whom I'd told about his having been away. （关于他外出我告诉了谁）
He's good at whatever he is does. （他做无论什么事）
5．What, whatever, which, whichever, whose本身有意义，且在从句中作定语
What—“什么（样的）”，whatever— “无论什么（样的）。作定语。
Which—“哪个/些”，whichever—“无论哪个/些”。作定语。
Whose—“谁的”，在从句中作定语。
I wanted to know which school it was you went to. （那个学校）
I didn't know what college I wanted to go to. （什么大学）
I can't remember whose idea it was for us to meet again. （谁的主意）
Whatever doubts he might have had about Ingrid were all over now. （无论什么怀疑）
Learn to relax by whichever method suits you best. （无论什么方法）
㈢ 英语的各种从句的语法问题、、、
最常见的就是：宾语从句；还有就是：状语从句、定语从句；高中的话，还有：同内位语从句、容主语从句、表语从句。
其实，判断是哪种从句就是看它在句子中作什么成分，就叫什么从句。
宾语从句 注意其 语序！！ 用陈述语序；即：主语+can/will/should...+谓语+宾语。
状语从句主要有条件状语从句和时间状语从句等，遵循“主将从现”原则，即主句用将来时，从句用一般现在时代替将来时。
定语从句：首先判断先行词，再判断用哪个引导词；
同位语从句就是看从句是不是对从句前的名词的解释说明，是的话就叫同位语从句；
表语从句就是作句子的表语；
主语从句顾名思义，作句子的主语；一般由what来引导。
具体的从句的详细讲解，请你与我保持联系，可以随时为你解答。
㈣ 英语状语从句的语法知识
状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。 现分别列举如下:
1． 时间状语从句

特殊引导词：lest, in case, for fear that，in the hope that, for the purpose that, to the end that
The boss asked the secretary to hurry up with the letters so that he could sign them.
The teacher raised his voice on purpose that the students in the back could hear more clearly.
5． 结果状语从句

特殊引导词：such that, to the degree that, to the extent that, to such a degree that,
He got up so early that he caught the first bus.
It’s such a good chance that we must not miss it.
To such an degree was he excited that he couldn’t sleep last night.
6． 条件状语从句

7． 让步状语从句

㈤ 关于英语从句语法的一些问题
1 不可以。我们只能怀疑比较确定的内容，不能怀疑模棱两可的内容。
我怀疑你帮我交版话费了。（权肯定句）
我怀疑你没帮我交话费。（否定句）
但是我不可能既怀疑你给我交话费了，又怀疑你没给我交话费。
if表示“是否”，即两种情况都可能，这种怀疑不合理，所以不能用在doubt之后。
2 的确是虚拟语气。
虚拟语气不仅仅表示难以实现的愿望，也可以表示真实的愿望。
I wish he could give up smoking(可能有一定难度，但是我的愿望是真实的)
本句也是如此，可能tom一贯粗心，下一次不粗心不很现实，但愿望是真实的。
㈥ 学英语的语法和从句需要抓住什么要点或技巧
语法就是靠背了，从句的话可能先理解整个句子，注意一定是整个，再根据意思判断that或其他插在那最好。 另外，熟能生巧是任何难题的解决办法，熟了感觉就出来了

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.

*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。

*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。

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

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 savings
It 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。

2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+谓语”。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中，谓语动词常用虚拟语气，表示与事实相反。

Everything went on as usual as if nothing had happened.
