中考英语核心语法6大词性、8大时态、3大从句，你值得拥有，希望能够帮助到你！总之，语法部分是英语学习的重点和难点。

语法知识掌握得好，将大大加快英语学习的进程。

本文归纳了六大词性、八种基本时态以及初中生需要掌握三种基本从句。

希望对广大中学生们有所帮助。

一. 词法1. 名词（1）名词的可数与不可数可数名词指表示的人或事物可以用数来计量，它有单数与复数两种形式。

不可数名词指所表示的事物不能用数来计量。

物质名词与抽象名词一般无法用数目，来统计，都成为不可数名词。

不可数名词前一般不能用冠词a、an来表示数量，没有复数形式。

要表示“一个……”这一概念，就须加a piece of这一类短语。

要注意许多名词在汉语里看来是可数名词，在英语里却不可数。

如：chalk，paper，bread，rice，grass，news等。

（2）名词复数的规则变化A.一般情况下加-s。

B.以s,x, ch,sh, 结尾的加-esC.以辅音字母加y结尾的改y为i再加-esD.以f，fe结尾的，去掉f或fe，变成v再加-es（3）名词的所有格A. 单数名词词尾加’s，复数名词词尾若没有s，也要加’s。

如：the worker's bike，the Children’s ballB. 表示几个人共有一样东西，只需在最后一个人的名字后加’ s若表示各自所有，则需在各个名字后’s。

如：This is Lucy and Licy’s room.These are Kate's and jack’s rooms.C. 如果是通过在词尾加—s构成的复数形式的名词，只加’。

如：the students’books，the girls’blouses(另外：名词+of+名词名词是有生命的，我们就用’s结构来表示所有关系。

如果名词所表示的事物是无生命的，我们就要用名词+of+名词的结构来表示所有关系。

)2. 代词人称代词，物主代词，反身代词，指示代词，不定代词（1）人称代词第一人称单数I me my mine myself复数we us our ours ourselves第二人称单数you you your yours yourself复数you you your yours yourselves第三人称单数he him his his himselfshe her her hers herselfit it its its itself复数they them their theirs themselves（2）物主代词物主代词的用法：形容词性物主代词后面一定要跟上一个名词；名词性物主代词可作主语、表语、宾语。

高考英语语法复习：八种状语从句的用法状语从句状语从句有时间、地点、原因、目的、方式、结果、条件、让步等八种。

一、时间状语从句：引导词有after，before，as，once，since，till，until，when，whenever，while，as soon as，the moment/minute…(一…就)，the time,the day,every time,next time,each time，by the time of，no sooner…than(一…就)，hardly…when(一…就).例如：Each/Every time he comes here,he will drop in on me.每次他来这儿他都顺便看我.He was ill last time I saw him.上次我见到他时他病了.No sooner had she heard the news than she cried.她一听到这个消息就哭了.[辨析]when与whilewhen引导的从句动词可以是延续性的或短暂性的，while引导的从句中动词必须是延续性的;在“be…when…”句式中when表“at that time(就在这时)”意，这样用的when不能换为while;while有时并不表示时间，而表示对比，意“而”、“却”，when无这样的用法。

例如：When I got home I found the door locked./While(或When)we were working in the fields,it suddenly began to rain./He was wandering through the streets when a bike hit him./His pencil is red,while mine is yellow.[辨析]till与until一般情况下可以互换，但until可以位于句首，till则不能。

考研英语基础语法扎实的语法功底对于考研解题是很重要的。

据总结，最令大多数考研学生头疼的基础语法现象主要有以下几项：英语的基本句式、形容词性（定语）从句、名词性从句（主语从句，表语从句，宾语从句和同位语从句）、副词性（状语）从句、As 的用法。

下面将对以上语法点详解，并通过练习进一步强化对它们的掌握。

一、英语的基本句式（一）英语句子的主要成分英语句子主要由主语，谓语，宾语（直接宾语和间接宾语），定语，状语，补语（主语补语和宾语补语），表语（主语补语的一种），同位语，感叹语，插入语等构成。

（二）英语的五大句式一)主+ 系+ 表语例如：You are a baby.系动词：联系动词（Link Verb）是一种表示谓语关系的动词，作为系动词，它本身有词义，但不能单独用作谓语，后边必须跟表语，构成系表结构说明主语的状况、性质、特征等情况。

系动词可以是be动词，也可以是某些实义动词。

例如：The dog looks dangerous.五大类常见系动词：1）be动词--用来表示主语状态。

例如：He is a teacher.2）“持续类”--用来表示主语继续或保持一种状况或态度。

这类系动词主要有：例如：I am sorry to have kept you waiting.This matter rests a mystery.3）“表象类”--用来表示"看起来像"这一概念这类系动词主要有：例如：He seems （to be）very sad.4）“感官类”--用来表示“感觉”“触觉”等这类系动词主要有：例1：It sounds reasonable.例2：-Do you like this sweater?-Yes, it __________ very soft.A. is feelingB. feltC. feelsD. is felt5）“变化类”--这些系动词表示主语变成什么样这类系动词主要有：例如：It worried her a bit that her hair was turning gray.The rumor proved false.His plan turned out a success.二) 主语+不及物动词+（状语）例如：He changed a lot.You cried loudly.注意：该句型可接状语。

从句的分类六大从句类型主语从句用作主语.That the earth is round is true.宾语从句用作宾语;Do you know where he lives表语从句用作表语.My opinion is that you should not go alone.同位语从句用于解释说明前面的名词,与先行词同位或等同的从句叫作同位语从句;其关联词多为that;The fact that the earth is round is true.that从句用于解释说明the fact定语从句相当于一个形容词,用于修饰前面的名词;定语从句一般皆放在被它所修饰的名代词之后,这种名代词就叫作先行词Antecedent;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用作主语、宾语、定语等；关系副词在定语从句中用作状语;The student who answered the question was John.状语从句相当于一个副词,修饰主句中的动词, 形容词和副词, 通常有从属连词引导, 按其意义和作用可分为时间, 地点, 条件, 原因, 让步, 目的, 结果, 方式, 比较.等When it rains, I usually go to school by bus.If he comes tomorrow, you will see him.He returned home to learn his daughter had just been engaged.You must speak louder so that /in order that you can be heard by all.Since /As the weather is so bad, we have to delay our journey.从句划分技巧主句和从句的划分方法是相同的;句子的成分从谓语动词处来划分比较容易;谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语;定语从句VS同位语从句定语从句是先行词的修饰语,它不涉及先行词的实质内容,在定规从句中“that”往往充当某一成分且作宾语时可以省略;同位语从句是对中心词的内容作进一步的解释和说明,表明中心词语的具体、实际内容;“that”在同位语从句中不充当任何成分且不可以省略;从句划分练习1. It is quite clear that the crime was down deliberately.2. She suggested that he do it at once.3. That the earth is round is true．4. The problem is not who will go but who will stay.5. The student who answered the question was John．6. Have you any idea how soon they’re coming.7. My original question, why he did it at all ,has not been answered.8. When it rains, I usually go to school by bus．9. What you need is more practice.10. It is still a question when we shall have our sports meet.11. I think it best that you should stay here.12. The question is whether it is worth doing.14. We must find out who did all these.15. Jack is no more frightened than Mike is.16. We expressed the hope that he would come to China again.17.

thought came to him that maybe the enemy had fled the city．他突然想起可能敌人已经逃出城了.五、同位语从句与定语从句的区别.1、同位语从句与前面的名词是同位关系,即说明它前面名词的内容；而定语从句与前面的名词是修饰与被修饰关系,即限定它前面的名词范围,或补充一些情况.如：The news that l have passed the exam is true．我通过了考试这一消息是真的.同位语从句,即从句所表达的意思就是前面名词的内容.）The news that he told me just now is true．他刚才告诉我的消息是真的.定语从句,从句对前面名词起修饰限制作用,即“他告诉我的”那个消息,而不是别的消息.）2、引导同位语从句的that是连词,在从句中不充当任何成份,而引导定语从句的that是关系代词,除起连接作用外,还在从句中充当主语、宾语或表语等.如：The idea that computers can recognize human voices surprises many people.计算机能够识别人的声音的想法使许多人感到惊奇.that在从句中不充当任何成份.）一个名词(或其它形式)对另一个名词或代词进行修饰,限定或说明,这个名词(或其它形式)就是同位语.同位语与被它限定的词的格要一致,并常常紧挨在一起.1) 非独立的同位语：常出现在被限定词前Bruce Lee (姓名) 李小龙Graf Schmidt (称号,浑名) 施密特伯爵Doktor Wang
