I. 可数名词名词可分为可数名词和不可数名词两部分。

其中，可数名词是表示能够计算的人或物的名称，他们通常有单数和复数的形式。

单数通常用a,an或者是one来表示。

an用在元音字母的前面。

如：a desk, an apple, one boy.·可数名词的变化规则1、直接在单词的后面加-s.photo---photos book---books egg---eggs student---students pen---pensvillage---villages cloud---clouds flower---flowershand---hands map---maps girl---girls2、如果单词以s,x,ch,sh结尾，通常要在单词后面加-es.bus---buses class---classes box---box dress---dresses peach---peacheswatch---watches fish---fishes3、以辅音字母+y结尾的单数名词要把y变为i，再加-es.如果y的前面是元音字母，则直接加上-s.family---families story---stories baby---babies day---days toy---toys boy---boys4、以f,fe结尾的单词，要把f,fe变为v，再加-es.knife---knives wolf---wolves shelf---shelves5、以-o结尾的名词，如果不是外来词或缩写，就加-es，否则加-s构成复数。

goose---geese foot---feet tooth---teeth woman---women man---mensheep---sheep fish---fish deer---deer people---people child---childrenmouse---mice7、有些名词是通常以复数形式出现的，如：shoes, pants, boots, glasses等。

1II.不可数名词1.一般来说，不可数名词主要是以物质名词与抽象名词为主。

它们通常没有复数形式，也不能与a ,an 连用。

在表示“一”或“几”的数量概念时，不可数名词必须与相应的量词连用。

如果时表示复数的数量关系时，则把量词变化，不可数名词不变。

修饰不可数名词的数量词语有：some, any, much, a lot of, a little等。

例如：a box of milk 一盒牛奶some water 一些水much food 大量的食物 a little time 一点时间2.some 与any 词语辨析some与any都表示“一些”，但它们的用法不同。

some用在肯定句中。

而any用在否定句与一般疑问句中。

同学们要特别注意的是：some还可以用在客气请求的一般疑问句中。

例子：I have some beautiful stamps.（肯定句）I don’t have any beautiful stamps.（否定句）Do you have any beautiful stamps?（一般疑问句）A: Can I have any some bananas?B: Sure.（客气请求的一般疑问句）3.many ,a lot of ,much 词语辨析many ,a lot of ,much ,这三个词都是表示“许多”。

many是用来修饰可数名词, much用来修饰不可数名词，a lot of则用来修饰可数与不可数名词。

例子：Peter has many friends .（可数名词的前面）Peter has much food for his birthday party. （不可数名词的前面）Peter has a lot of friends. （可数名词的前面）Peter has a lot of food for his birthday party. （不可数名词的前面）·不可数名词的归类1、表示液体：water, juice, milk, coffee, coke2、表示自然现象：snow, rain, ice3、表示食品类：rice, jam, honey, meat, bread, mutton, beef, tofu, eggplant, pork, chicken,fish, food4、其它类：newspaper, news, homework, housework21.给出下列单词的复数形式。
