可数名词不可数名词专讲

1、初中英语可数名词和不可数名词专讲一、名词：名词是所有事物的名称，包括人、物及抽象概念。名词分为普通名词和专有名词两大类。名词在句子中作主语，宾语或表语等。1 .专有名词：专有名词是某些人、事物、机构、组织等特有的名称。主要包括：人名、地名、国名、党派名称等。如：Churchill （丘吉尔）、Tokyo （东京）、China （中国）等。Guangzhou, Mike, UNESCO 一般情况下第一个字母要大写，前面不加定冠词the o2 .普通名词普通名词是某类人、事件、物体和抽象概念的名称。根据所指代物体的特征，普通名词又可分 为以下四类：A.个体名词：表示人或物体中可以数清的单个体。如：

2、 student （学生）、pen （钢笔）、birdB.集体名词：（即集合名词）表示由个体组成的集合体。如： people （人民）、police （警察）、 family （家庭）、class等C.物质名词：表示构成物体物质的不可数名词，或表示无法分为个体的物质的名词。如：water （水）、air （空气）、wood （木头）、milk （牛奶）等。D.抽象名词：表示动作、状态、品质、情感等非具体化的抽象概念。如：work （工作）、peace （和平）、love （爱）等。一般来说，个体名词和集体名词多为可数名词，物质名词和抽象名词多为不可数名词。二、可数名词和不可数名词。一）不可数名

3、词不可数名词意味着这些名词只能是单数，没有复数形式，不能与数目字如one, two等连用，也不能加不定冠词a（n）。不可数名词没有单数、复数之分，但我们在生活中有时候又必需给这些 词计量，我们于是采用这种方法：a+表示这些东西的单位+of+不可数名词如：a cup of tea, a box of milk, a piece of paper等。如果为了表示多个的概念，我们就将表示这些东西的单位变成复数即可。如：a cup of tea-3 cups of tea a box of milk-12 boxes of milk A piece of paper-100 pieces of pap

4、er*需要注意的是，a.当物质名词转化为个体名词时为可数。比较：Cake is a kind of food.蛋糕是一种食物。（不可数）These cakes are sweet.这些蛋糕很好吃。（可数）b.当物质名词表示该物质的种类时，可数。例如：This factory produces steel.（不可数）We need various steels.（可数）c.当物质名词表示份数时，可数。例如：Our country is famous for tea.我国因茶叶而闻名。Two teas, please.请来两杯茶。2）抽象名词表示具体的事例时也可数。例如：four freedoms

5、 四大自由 the four modernizations 四个现代化注意事项：1.不可数名词没有复数变化，不能用 a, an,但可用the,或不用冠词，如：bread is the usual eakfast.2虽然不可数名词没有复数变化，但量词超过一时要加复数。如： three cups of coffee, fivebottles of water 3有量词修饰时注意名词是否可数，不可数时用单数，可数时用复数，如：ten bags of riceten baskets of eggs二 ） 可数名词:一般来说个体名词和集体名词可以用数目来计算，称为可数名词。可数名词有单数和复数两种形式。

6、例如：a book, two books, a student, three students, a family, many families名词单数变复数变化如下：1 . 词尾直接力口 s 如：cat-cats bag-bags da广days friend ffriends; catfcats; style fstyles;sport fsports; piece fpieces2 . 以 s, x, sh, ch结尾的词力口 es 如：class-classes match-matches boxboxes dish - dishes例：busbuses;fox foxesmatchm

9、knife -knives; life -lives; leaf -leaves; sc （围巾）-scarves口诀：树叶半数自己黄，妻子拿刀去杀牛；架后窜出一只狼，就像小偷逃命忙。解释：leaf （树叶）half （一 半）self （自己）wife （妻子）knife （刀子）calf （小牛）shelf （架子）wolf （狼）thief （小偷）life （生命）但是，也有例外。口诀：海湾农奴信酋长，悬崖证据上顶房。在这些词中，由单数变复数时，直接在词尾加-s构成，即：海湾（gulf - gulfs）农奴（serf - serfs）信（belief -beliefs）酋长（chief

10、 - chiefs）,悬崖（cliff -cliffs）证据（proof - proofs）上顶房（即房顶、屋顶roof - roofs）5以辅音加o 结尾的词常加es, 如 : tomatoes, potatoes, heroes. 元音加 o 结尾直接加S.如:radios, zoos, pianos.特殊情况：photos以-o结尾的名词，如果不是外来词或缩写词，就加-es,否则加-s构成复数。（有生命的加es,无生命的加s）口诀：黑人和英雄吃土豆和西红柿negroes and heroes eat tomatoes and potatoes反例：radioradios, pianofp

JuiceHow many 和 how much 的用法这两个字虽然都是，很多的意思，但many后面是接可数名词，而 much后面是接不可数名词一、所修饰词的不同how many用来修饰

21、可数名词的复数，它的句式是：How many+复数名词+一般疑问句十how much 用来修饰不可数名词，表示数量，也可单独使用。二、 how many 的用法1 .对there be句型中主语的数量如：some, five, only one等提问时，如果主语是可数名 词,不管主 语是单数还是复数一般都用复数形式提问，因为问话人不知道具体的数量是多 少，而且many只 能接可数名词复数形式，所以be 一定要用are.即用How many+可数名t复数+are there+地点/ 时间状语的句型结构.例如 :(1) There is a book on the desk.网 how many

22、改为特殊疑问旬) How many books are there on the desk(2)There are seven days in a weekX(戈U线部分进行提问 ) How many days are there in a week 记忆口诀 how many在句首洛词复数跟着走，一般问句紧相随，其它成分不要丢.2、 how much的用法(1)用来询问事物的数量，后接不可数名词。例如： How much milk is there in the glass玻璃杯里有多少牛奶(2)用来询问事物的重量。例如：一 How much does the pig weigh这头猪多重E

23、ighty kilos.(3) how much意为“多少钱”时，可单独使用，也可构成词组 how much money,但英语 中常省略money,用来询问某物的价钱、价格。(注意：how much询问价格时，它的回答若是中国的货币单位应采用汉语拼音 yuan,fen来表 示，几角常采用几十分来表示，字母用小写，且不用复数。例如： 一How much is the eraser 这块橡皮擦多少钱一Ninety two fen.九角二分。(4)用来询问数字计算的结果，相当于 what。例如：一How much is three plus one 三力口一等于多少 IC's four.等
