初中英语语法大全——名词

初中英语语法大全——名词 一、名词概述 1.名词的定义 名词是表示人、事物、地点、现象及其他抽象概念等名称的词。英语中的名词有可数名词和不可数名词之分;有其所有格形式;在句子中通常做主语、宾语、宾语补足语、表语、定语等。 2.名词的分类 名词分为专有名词和普通名词两类。普通名词又分为个体名词、集体名词、物质名词和抽象名词。个体名词与集体名词多数是可数名词,而物质名词与抽象名词多数是不可数名词。

二、名词的数 名词按照其可数性可以分为可数名词和不可数名词。可数名词是指可以直接计算数目的名词。个体名词和集体名词多数是可数名词;不可数名词是指无法直接用数目计算的词。物质名词和抽象名词多数是不可数名词。 1.可数名词的数 在英语中,可以直接用数字进行计算的名词是可数名词,不能直接用数字进行计算的名词是不可数名词。通常个体名词和集体名词可以用数目来计算,视为可数名词;物质名词和抽象名词往往指泛指的物质或者抽象的概念,不能用具体的数字来表示,视为不可数名词。专有名词往往只指一个人或物,因此没有必要再用具体的数字来修饰,一般也视为不可数名词。

eg: I was having dinner at a restaurant. eg: The two children are playing table tennis in the school. eg: Mr.Black gave us some advice on how to learn English well. eg: Paris is the capital of France. ①规则复数变化形式 可数名词在表示两个或两个以上的概念时需要用复数形式。可数名词单数形式变成复数形式的一般规则如下表:

英语祈使句详解(664)

英语祈使句详解 1. 祈使句的概念 表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。用于祈使句 句首的动词总是用原形,不能用其他形式。如: Shut the door! 把门关上! Have a cup of coffee! 喝杯咖啡吧! Let them go by train. 叫他们坐火车去吧。 祈使句的主语通常为第二人称(you),但一般都被省略,只有在特殊的情况下才把主语(you)补充出来。如: You be quiet! 你安静! You go and tell him, Chris. 克立斯,你去告诉他。 You wait here for a moment. 你在这儿等一会儿。 有时祈使句的主语也可以是everybody, somebody, anybody, nobody等不定代词。如: Stand up, everybody! 全体起立! Nobody move. 任何人都不许动。 2. 祈使句表示强调 为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词d 务必”等。如: o,此时通常译为“一定”“ Do be careful. 务必要小心。 Do have some more tea. 一定再喝点茶。 Do let me go. 一定让我去。 副词never和always有时可用于祈使句句首,表示强调。如: Never do that again. 再不要这样做了。 Always look in the mirror before starting to drive. 一定要先看看反光镜再开车。 3. 祈使句的否定式 构成祈使句否定式的方法很简单,那就是在动词原形前加don’t——不管祈使句所用的动词为什么性质动词,情况都是一样。如: Open the window. 把窗户打开。 →Don’t open the window. 别把窗户打开。 Come next Monday. 下周星期一来。

初中英语语法大全:名词

初中英语语法大全:名词 一名词的定义:表示人、事物或抽象概念的名称的词。 二名词的分类: 名词可以分为专有名词(Proper Nouns)和普通名词 (Common Nouns),专有名词是某个(些)人,地方,机构等专有的名称,如Beijing,China等。普通名词是一类人或东西或是一个抽象概念的名词,如:book,sadness等。普通名词又可分为下面四类: 1)个体名词(Individual Nouns):表示某类人或东西中的个体,如:gun。 2)集体名词(Collective Nouns):表示若干个个体组成的集合体,如:family。 3)物质名词(Material Nouns):表示无法分为个体的实物,如:air。 4)抽象名词(Abstract Nouns):表示动作、状态、品质、感情等抽象概念,如: work。 … 注意专有名词一般第一个字母要大写。专有名词前一般不加冠词。 名词的种类 注意物质名词与抽象名词一般无法用数目来计算,称为不可数名词。不可数名词前不能加冠词a或an来表示量。 (三)名词的数 1.可数名词有单数和复数两种形式: 1.单数 英语中,如果我们要表示一本书、一只鸟、一棵树等概念时,要用名词的单数形式,表示名词的单数,要在名词前加冠词a或an。 This is a desk . 这是一张书桌。

[ There is an orange on the table . 桌上有一个橘子。 an orange 一个橘子an new orange (×)→a new orange (○) 一个新橘子 a desk a old desk (×)→an old desk (○)一张旧课桌 a和an的使用区别 a加在以辅音开头的名词前,如a book,a pen。 an加在以元音开头的名词前,如an egg,an apple。 注意 ! 有时a,an后面紧接的不是单数名词,而是a (an) +形容词+单数名词的形式。 这时判断用a还是an来表示“一个”的概念时,要看形容词开头字母的发音,而不 是看名词。 2.复数 英语中,如果要表示两本书、三个学生、四把椅子这些两个或两个以上的概念时,要用名词的复数形式,名词的复数形式是在单数名词后加上词尾-s或-es构成的。 变复数时情况如下: (1)一般情况下,在词尾加s. eg.book——books,dog——dogs,pen——pens,boy——boys 以轻辅音结尾的名词后的s的读音为[s],以浊辅音和元音结尾名词后的s读音为〔z〕。 (2)以s,x,ch,sh结尾的词名词变复数时,要在词尾加es.

英语祈使句详解讲课稿

英语祈使句详解 1.祈使句的概念 表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。用于祈使句句首的动词总是用原形,不能用其他形式。如: Shut the door! 把门关上! Have a cup of coffee! 喝杯咖啡吧! Let them go by train. 叫他们坐火车去吧。 祈使句的主语通常为第二人称(you),但一般都被省略,只有在特殊的情况下才把主语(you)补充出来。如:You be quiet! 你安静! You go and tell him, Chris. 克立斯,你去告诉他。 You wait here for a moment. 你在这儿等一会儿。 有时祈使句的主语也可以是everybody, somebody, anybody, nobody等不定代词。如: Stand up, everybody! 全体起立!Nobody move. 任何人都不许动。 2.祈使句表示强调 为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词do,此时通常译为“一定”“务必”等。如:Do be careful. 务必要小心。Do let me go. 一定让我去。 副词never和always有时可用于祈使句句首,表示强调。如: Never do that again. 再不要这样做了。 Always look in the mirror before starting to drive. 一定要先看看反光镜再开车。 3.祈使句的否定式 构成祈使句否定式的方法很简单,那就是在动词原形前加don’t——不管祈使句所用的动词为什么性质动词,情况都是一样。如: Open the window. 把窗户打开。→Don’t open the window. 别把窗户打开。Come next Monday. 下周星期一来。 对于以let us或let’s开头的祈使句,其否定式通常是在不定式之前放一个not。如: Let’s tell him the truth. 我们把实情告诉他吧。→Let s not tell him the truth. 我们不要把实情告诉他。 但在日常口语中,我们也可以把don’t放在let’s之前。如:Let’s don’t tell him the truth. 我们不要把实情告诉他) 4. 祈使句与连用please 为了使祈使句的语气变得委婉,我们可以在祈使句的句首或句末加上please——若加在句首,其后不用逗号;若加在句末,则通常会在please前加一个逗号。如: Step this way, please. 请这边走。Please type your letter. 请把你的信打出来。 Open the window, please. 请把窗户打开。 如果是否定祈使句,则通常将please加在don’t之前。如: Please don’t get angry. 请不要生气。 5.祈使句的时间概念 祈使句所表示的时间总是指将来,所以与它连用的句子原则上要用将来时态来与它呼应。如: Give me a hand, will you? 帮我一个忙,好吗? 由于give me a hand表示隐含将来意义,所以句中的will you 不能改为do you。 Try again and you will succeed. 你再试就会成功。由于句中的try again隐含将来意义,所以句中用了you will succeed,而不是you succeed。 Don’t do that again or you’ll be in trouble. 别再干那个了,否则你会有麻烦。句中的don’t do that again指的是以后不要再干那事了,由于隐含有将来意义,所以句中用了you’ll be in trouble,而没有用you are in trouble。6. 祈使句的省略 一般说来,祈使句总是要以动词原形开头,但是,在某些特殊情况下,我们可以只用一个词或短语来表示祈使句的意义。如: Just a few please. 请给几个就行了。 A little more slowly please. 再慢一点。 A pound of butter. 给我一磅黄油。Two teas and four coffees, please. 请来两杯茶和四杯咖啡。
