1、学习必备 精品知识点 小学英语语法汇总（蓝本）可数名词与不可数名词“分家”一、可数名词与不可数名词的区别 可数名词是可以按个数来计算的普通名词，分为个体名词(表示某类人或事物中的个体，如 worker,farmer,desk,factory 等)和集体名词(表示作为一个整体来看的一群人或一些事物，如 people,family 等)。不可数名词是不能按个数来计算的普通名词，分为物质名词(表示无法分为个体的物质，如 meat,rice,water,milk,orange 等)和抽象名词(表示动作、状态、情况、品质等抽象概念，如 work,homework,time,health,friendsh
2、ip等)。强调：不可数名词默认为单数，用 is 或者 was；不要根据 some、any、a lot of等词去作判断。二、可数名词的家务事 可数名词有单数和复数两种形式。指一个人或一件事物时，用单数形式；指两个或多个人或事物时用复数形式。名词由单数形式变成复数形式的规则如下：1.一般的名词词尾直接加-s。如：book books house houses day days 读音：清辅音后读s，浊辅音和元音后读z。2.以 s,ss,ch,sh,x 结尾的在词尾加-es。如：bus buses glass glasses watch watches dish dishes box boxe s
3、读音：iz 3.以辅音字母+y结尾的，将 y 改为 i 再加-es。如 city cities factory factories 读音：z 4.以 f 或 fe 结尾的，将 f 或 fe 改为 v 再加-es。如：half halves leaf leaves knife knives wife wives thief-thieves 读音：z 5.特例（常考）child children mousemice man men womanwomen policeman policemen (规律：man men)tomato tomatoes potato potatoes 注：黑人 英雄 土
4、豆 西红柿加 es 其余加-s,如：photo photos hero h eroes negro negroes 读音：z foot feet tooth teeth oo 变 ee sheep,Chinese,Japanese,fish 单、复数同形 people 单数形式表示复数意义，要求谓语动词用复数；people 的复数形式 peoples 通常指多个民族。三、不可数名词的家务事 1.不可数名词没有复数，作句子主语时，谓语动词用单数形式。如：The food is very fresh.2.有的不可数名词也可以作可数名词，有复数形式，但意义发生变化。如：water(水)waters(
5、水域)orange(橘汁)oranges(橘子)3.很多的不可数名词表示泛指时为不可数，表种类时就可数，意义不发生变化。如：fruit fruits food foods fish fishes hair hairs 4.计算不可数名词的数量，要在数词和不可数名词之间加上“量词+of”如：a glass of water a piece of paper a bottle of juice 5.判断步骤：如是 am、is 或 was原形 读句子读该单词认识该单词理解意思看 be 动词 如是 are 或 were加 s 或 es 学习必备 精品知识点 A.用所给名词的适当形式填空 1.How m

10、 orange,an old man,an English watch,an hour 2、定冠词：the 用在单数或者复数名词前，没有具体意思，翻译为这、那。基本用法：（1）表特指某（些）人或某（些）事物。如：The map on the wall is new.（2）表示说话者双方都知道的人或事物。如：Look at the picture,please.（3）表示再次提到前面谈过的人或事物。如：This is a stamp.The stamp is beautiful.（4）用在表示世界上独一无二的事物前。如：the sun太阳 the moon月亮 the earth地球 （5）用在
