1、小学英语语法基础知识大全蓝本小学英语语法汇总（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
2、, friendship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 dis
3、hes box boxes 读音：iz3. 以辅音字母+y结尾的，将y改为i再加-es。如 city cities factory factories 读音：z4. 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：z5. 特例（常考） child children mousemice man men womanwomen policeman policemen (规律：man men) tomato tomatoes potato potatoes 注：黑人
4、英雄 土豆 西红柿加es其余加-s,如：photo photos hero heroes negronegroes 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) wat
5、ers (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esA.用所给名词的适当形式填空1.

That is her ruler. = That is hers. 看后面有没有名词，如有，就用形容词性物主代词；如无，就用名词性物主代词。 牢记：单数复数人称 代词主格Iyouhesheitweyouthey宾格meyouhimherit
