不可数名词前面不能用a或者an来修饰，也不能在后面加s或者es，要用量词词组，如:
a piece of cheese/news/paper/advice…
a bar of chocolate/soap…
a pound of tea/sugar/tobacco…
a tin/glass/cup/bottle… of
some和any都可以表示一些，但是any用于疑问句和否定句中，some用于肯定句中，两者均可以修饰可数名词和不可数名词，如：
Is there any water in that cup?
Is there any birds in that tree?
No, there is not any.
Yes ,there are some.
