可数名词和不可数名词的概念
Countable nouns：noodles，potatoes，carrots，cabbages
可以计数的名词称为可数名词。大多数水果、蔬菜属于可数名词
一般有单数与复数两种形式，单数形式前面可加a, an或数词来修饰.

an用在辅音音素开头 a cow a uniform a book a car
[ ju n f m]
[ a (r)]
Uncountable nouns：mutton，milk，beef，rice
不可计数的名词称为不可数名词。主食、肉类、饮料多属于不可数名词
没有复数形式，前面不能用不定冠词a,an,也不能直接加数词，但可以跟某些量词短语搭配，表示数量。
如: a glass of water, two cups of tea.
可数名词变复数形式比较多样,其变化规则如下：
变化规则 例子 1 一般情况下，直接末尾加-s book-books pen-pens dog-dogs
2 以s、x、sh、ch结尾，末尾加-es watch-watches box-boxes bus-buses
3 以“辅音字母+y”结尾，变y为i，再加-es baby-babies story-stories candy-candies
以“元音字母+y”结尾，直接末尾加-s boy-boys day-days toy-toys

不规则变化 例子 改变单词中间的元音字母 man-men woman-women

其余的国家加-s American-Americans German-Germans
（德国人）
不可数名词量的表达
不可数名词的量可以用 “a/an/基数词+表示量的名词（类似语文量词） + of + 不可数名词” 表示，这些表示量的名词有单复数形式的变化。这一结构作主语时，谓语动词的单复数形式要与表示量的名词保持一致。常见的量词有：piece(条、块、片、张、份、则)；glass(玻璃杯) ； cup(茶杯) ； bottle(瓶)；basket(篮)、bag(袋)、box(箱，盒)等。
eg：a piece of paper 一张纸 three pieces of paper 三张纸
a piece of meat 一块肉 a piece of bread 一片面包
a glass of milk 一杯牛奶 a cup of tea 一杯茶
six bottles of water 六瓶水 a basket of food 一篮食物
a bag of rice 一袋大米 a box of juice 一箱果汁
There is a bottle of juice on the table. (谓语动词is与a bottle保持一致)
There are three bowls of mutton soup on the table. (谓语动词are与three bowls保持一致)
