语法专项II. 名词:在我们身边存在着形形色色的人和事物,它们都有自己的称呼,我们用来称呼它们的词就是名词,概括来说表示人、事物、地方、现象等的名称的词都叫名词。一. 名词的种类:名词可以分为专有名词和普通名词,普通名词又分为个体名词和集体名词,物质名词和抽象名词。 1. 专有名词:专有名词是指人、地方、团体、机构等特有的名词,它的第一个字母必须大写,专有名词前一般不加冠词。 A. 表示人名:Li Bai,Mr Black,Doctor Zhang B. 表示地名:China,London,Zhong Guan Cun Street. C. 由普通名词构成的专有名词:the Spring Festival, the Palace Museum. 2. 普通名词:普通名词指一类人或东西或一个抽象的名标,它可以进一步分为个体名词、集合名词、物质名词和抽象名词四类。 A. 个体名词:表示某类人或事物中的个体:student,teacher,car. B. 集合名词:表示若干个体组成的集合体;family,police,people. C. 抽象名词:表示动作、状态、品质、感情等抽象的概念:music,love D. 物质名词:表示无法分为个体的物质或实物:water,tea,air二. 名词的数:表示可以计算数目的人或物称为可数名词,表示一个用单数,两个以上用复数,可数名词单数前面一般要用不定冠词a / an,可数名词复数是在单数名词后面加“s”或“es”。可数名词复数前不能用不定冠词a / an。 1. 单数可数名词,表示“一”的概念,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。 eg:a book, a tree, a shark an octopus,an apple,an egg 2. 复数可数名词:在英语中,如果要表示“二、三、四,”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。 A. 名词复数的规则变化。 a. 在一般情况下,词尾后加-s。 books,cups,beds,boys,horses b. 以s,x,sh,ch结尾的词,词尾加-es,读|iz| buses,boxes,dishes,watches c. 以f或fe结尾的词,先将f或fe变成v,再加-es,读|vz| halfhalves,knifeknives d. 以o结尾的词,词尾加-es或-s。 zoos,photos,radios,tomatoes,potatoes e. 以辅音字母加y结尾的词,先将y改为i再加-es。 cities,families,babies B. 名词复数的不规则变化。 manmen,toothteeth,childchildren,sheepsheep C. 有些名词只有复数形式 clothes,trousers,pants,glasses 3. 不可数名词表示量的概念时,在这些词前加上数量词。 eg:a cup of coffee,a piece of paper,three slices of breadII. 不定代词,我们所学的不定代词有all,both,each,every,some,any,many,much,(a)few,(a)little,either,neither,other,another,no,none以及含有some-,any-,no-等的合成代词,这些不定代词大都可以代替名词和形容词,在句中作主语、宾语、表语和定语。一. some,any及其合成词的用法。 1. 基本用法 some,any可与单、复数和不可数名词连用。 some用于肯定句中,而不能用于疑问句中,any一般用于否定句,疑问句和条件句中。 eg:I have some interesting books. There is some yogurt in the bottle. I dont have any money. Were there any sharks in the aquarium? 2. 特殊用法 在疑问句中,一般不用some,只有当问句表示一种邀请或者请求,或期待一个肯定的回答时才能用some。 eg:Would you like some more tea?二. all,both的用法 1. all代表或修饰四个以上的人或事物,或不可数的东西。 eg:We all like eat potato chips. All the students in our class went to the zoo. 2. both是指“两者都” eg:The twins both have long hair. There are many trees on both sides of the street.三. many,much,(a lot),a few,few,a little,little。这些词都可以表示数量,并且都可以修饰名词。 1. many,a lot,a few,few修饰可数名词;much,a lot,a little,little修饰不可数名词。 2. many,much,a lot,a few,a little表示肯定的意思:few,little表示否定的意思。 eg:How much relish do we need?
