some 和 any 的用法
some 和 any 均表示“一些”，作定语既可修饰可数名词，也可修饰不可数名词
some 一般用于肯定句中，any 多用于疑问句、否定句和条件句中
I have some pens.
He has some money.
Do you have any pens ?
Does he have any money ?
I don't have any pens.
If you have any pens, borrow me one.
但在疑问句中，说话人在表达请求、建议时，希望得到肯定回的答，应用 some
why not buy some apple？
为什么不买些苹果呢？
Would you like some more meat ?
你想再来点儿肉吗？
Shall I pour you some water ?
要不要我给你倒点水？
注意：
① some 有时可以和可数名词单数一起用，意为“某个”, 相当于 a certain
I once stayed at some hotel in Singapore , but I can't remember which one.
在新加坡，我曾在某个宾馆里住过，但我记不起来是哪个了。
② any 用在肯定句中, 意为“任何的”
You can visit me at any time.
你可以随时来找我。
