通过以上九个知识点的学习，我们可以更好地理解和运用英语语法。

掌握这些知识点，对于学习和提高自己的英语水平具有重要的帮助。

希望大家能够认真学习，不断练习，进一步提升自己的英语能力。

英语语法基本概念：１、什么是语法(grammar)：语法是语言的法则。

每一种语言都有一定的法则，英语语法就是英语的基本法则。

学英语必须学英语语法。

在英语国家长大的孩子，不学语法也会说英语，就像我们不学汉语语法也会说中国话一样。

但是我们不是生活在英语国家。

在我们的头脑里，汉语已经“先入为主”了。

在这种情况下，要学另一种语言（如英语），必须弄清英语与汉语的不同之处，也就是掌握英语的特色，这就是学语法。

２、词性：指作为划分词类的根据的词的特点。

英语词性包括：1)．Noun名词n. ：描述一个人、一个地点、一个东西或者一种想法的词。

共有两类：可数名词：有单复数变化的名词，多为事物名称。

不可数名词：一般无复数变化的名词，多为抽象名词。

2)．Pronoun代词pron. ：用来指代一个名词的词。

共四大类：人称代词：表示各类人称的代词如：I, we, they等。

物主代词：表示人或事物归属的代词如：your, mine.指示代词: 如：this, that, those these等。

疑问代词：如：which, who, whose, what。

3)．Adjective形容词adj. ：一个用来描述一个名词或者代词的词。

修饰名词，代词。

排列顺序：限定词，描绘性，大小新旧，颜色，来源/国别，材料质地，用途+名词。

注：修饰不定代词，须后置。

4)．Verb动词v. ：一个表示动作进行或者存在的状态的词。

共有四类：及物动词:可以直接跟宾语的动词。

不及物动词：不能跟宾语或不能直接跟宾语需添加介词再跟宾语的动词。

延续性动词：表示可持续发生的动作或状态的动词。

瞬间动词/终止性动词：表示结果或瞬间就完成的动词，在句中不能与一段时间连用。

5)．Adverb副词adv. ：副词是用来描述一个动作怎样完成、在哪里完成或者什么时间完成的词。

是修饰动词，形容词和副词的词。

如：very, so, slowly, finally等。

6)．Conjunction连词conj. ：一个用来连接几个词或者几组词的词7)．Preposition前置词，汉语中多叫介词prep. ：一个用来表明一个名词或代词和另一个词的关系的词。

英语专业四级考试语法复习资料一、考纲要求及语法知识常考点（一）名词、代词的数和格的构成及其用法1．有关名词的格的考点：名词可分为主格、宾格和所用格。

专业四级英语主要是考查名词所用格的掌握情况。

所有格可分为’s所有格与介词of所有格，前者一般用于有生命的名词，如：the boy’s ball，后者用于无生命的名词，如：the topic of the conversation （话题）。

另外还有双重属格，其表现形式为A of B’s，其中B必须是指人的名词。

如：a book of my wife’s（我妻子的一本书），而不能说a funnel of the ship’s.考点一：当名词表示地理、国家、城市、时间等词时，应该把它们当作有生命的名词对待，即用’s所有格。

如：Europe’s future 欧洲的未来Today’s newspaper 今天的报纸考点二：表示某物为两人或多人共有时，在最后一个人名后加’s，如果为词组内并列名词各自所有时，则要在各个名词后都加’s，例如：Mary and Linda’s book 玛丽与琳达（共同拥有）的书Tom’s and Peter’s fathers 汤姆的父亲与彼得的父亲考点三：人名’S所有格结构可以表示某人所在的店铺、家庭、学校与教堂等地点。

I am going to the tailor’s to get my dress. 我要去裁缝店拿回我的衣服。

I buy my meat at the Johnson’s 我常在约翰逊开的肉铺买肉。

They took part in the birthday party at Tom’s. 他们参加了在汤姆家举行的生日宴会。

2. 有关名词数的考点：考点一：复合名词的复数：一般而言，我们把核心词变为复数形式即可，如：passers-by, mothers-in-law; assistant directors；girl friends，但当修饰词是man，woman时，复合词各组成部分都要变为复数，例如：menservants，womenservants考点二：复数形式的名词用于单数概念，其谓语动词用单数。

独立主格结构独立主格结构（Independent Genitive）有两部分组成，前一部份是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。

前后两部分具有逻辑主谓关系。

独立主格结构在句中做状语，多用于书面语。

独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。

非谓语动词作状语，其逻辑主语须与主句主语保持一致。

若不一致，非谓语动词形式须另带主语，从而构成复合结构的形式作状语。

这种结构称为“独立结构”。

其中，非谓语动词主动用现在分词，被动用过去分词。

非谓语动词及其短语前面带有逻辑主语，逻辑主语的代词又是主格，故常称为“独立主格”。

“独立结构”在句中起状语作用，相当于状语从句，表示时间、原因、条件、方式或伴随等情况。

功能独立主格结构主要用于描绘性文字中，其作用相当于一个状语从句，常用来表示时间、原因、条件、行为方式或伴随情况等。

例如：表示时间The meeting being over, all of us went home. 开完会后我们都回家了。

Her work being done, she sat down for a cup of tea. 她干完了活，坐下来喝茶。

表示条件The condition being favorable, he may succeed. 若条件有利，他或许能成功。

表示原因There being no taxis, we had to walk. 没有出租车，我们只好步行。

He wrapped her up with great care, the night being dark and frosty. 夜又黑又冷，所以他把她裹得严严实实的。

表示伴随情况Almost all metals are good conductors, silver being the best of all. 几乎所有的金属都是良导体，而银则是最好的导体。

lapin bleu衷心感谢您的阅读，祝您考试成功！动词★复合时态中助动词的选择一.使用être作为助动词的情况1.所有的代（词式）动词；2.少数不及物动词（20个）——记住对联“上联：来(venir,revenir)去(aller)出(sortir)入(entrer)走(partir)；下联：生(naître)死(mourir,décéder)到(arriver)跌(tomber)留(rester)”，下(descendre)回(rentrer,retourner)成绩变(devenir)好（上(monter)去了），考试通过(passer)了。

另外添加两个动词——parvenir达到，抵达和survenir突然发生及物动词了 —— 去掉自反代词后为 直接及物动词 的要性、数配合，去掉自反代词之后为 间接及物动词 的不可以性、数配合。

二. 使用 avoir 作为助动词的情况除去 一、 所列举出的情形之外的动词 即：包含动词 être 和 avoir 在内的及物动词和大部分的不及物动词。

注意上述 20 个使用 être 作为助动词的不及物动词，还有其它作为及物动词的用法，意思 不同。

此时，就要使用 avoir 作为助动词了。

如：passer度过monter 搬上来 entrer 放进去rentrer 收回去tomber 打败对手 descendre 拿下去 sortir 拿出来 retourner 翻转动词 courir , marcher 等虽然“移动”，但是助动词要用 avoir ！ ★复合时态中过去分词的性、数配合 一、avoir 作为助动词的情况1 . 配合的条件： 过去分词的直接宾语位于它的前方，这个过去分词必须要与之性、数配合。
