countable / uncountable nouns 可数/不可数名词
可数名词与不可数名词
名词按其所表示的事物的性质可分为可数名词和不可数名词。可数名词表示可以用数目计数的名词；不可数名词表示不能直接用数目计数的名词。
用法区别
单复数形式：
可数名词 → 有单数和复数两种形式
不可数名词 → 没有单复数之分
修饰词：
可数名词 可直接用不定冠词a/an或具体的基数词修饰，如an apple, two girls
可用many，a few， few，some，any，a lot of，lots of 等词（组）修饰
不可数名词 不能直接用不定冠词或具体的基数词修饰。表示确切的量时，需用“冠词/基数词+表示计量单位的名词+of+不可数名词”结构，如a piece of bread, four cups of water
可用much，a little，little，some，any，a lot of，lots of 等词（组）修饰
谓语动词：
可数名词：作主语时，谓语动词与主语的单复数保持一致
不可数名词：作主语时，谓语动词用第三人称单数形式
提问（数）量：
可数名词 → 用how many提问
不可数名词 → 用how much提问
There are six apples on the table.
The bread tastes delicious.
Five spoons of honey are just right for the cake.
当不可数名词前表示计量单位的名词是复数时，谓语动词用复数形式
情况 构成方法 读音 例词

fox → foxes 狐狸
watch → watches 手表
dish → dishes 菜
以辅音字母加y结尾的名词 变y为i，再加-es 读/ z/ factory → factories 工厂
victory → victories 胜利
可数名词单数变复数的规则
规则变化：
以f(e)结尾的名词 变f(e)为v，再加-es 读/vz/ wife → wives
妻子
leaf → leaves
叶子
以o结尾的名词 词尾加-es 读/z/ tomato → tomatoes
西红柿
potato → potatoes
土豆
词尾加-s photo → photos

巧记感叹句的用法
Think and answer
How to determine (确定) whether to use what or how in an exclamatory sentence
一去：去掉主语和谓语部分（去主谓）
二看：看主语前有名词还是有形容词、副词或者没有其他单词。若有名词，用What；若有形容词或副词, 用How（是否有名词）。
三注意：What 类型单数名词前必须加 a/an，取决于形容词首音素； How 修饰“形容词+单数名词”; 当名词前面有many/ much/ few/ little，表示“多多少少”的时候，通常也用How来引导感叹句。
一去：去掉主语和谓语（去主谓）
1. _____ an interesting story Leo told me!
2. _____ I wish I could be an artist when I grow up!
3. _____ helpful tools they are! They help me a lot.
4. Jim rode around the lake yesterday. ______ great fun
