一般情况下,some用于肯定句,any用于否定句,疑问句和条件句中,都表示“一些”的意思.
如果提问的人期待对方肯定回答时,或者表达自己诚意邀请对方做某事时,常用some,而不用any.
还要注意,当some与可数名词单数连用时,其意思变为“某一.”而不再是“一些”；而any与可数名词单数连用,用再肯定句中时,其意思是“任何一.”,而不是“一些”的意思.
注意理解下面的例句：
I have some Chinese stroy books,but I don't have any English ones.
Do you have any questions to ask me?
If you have any problem,turn to me!
Would you like some more tea?
Do you have any ink?
Do you have some ink?
尤其对比最后两句,上面那句是一般问题,而下面这句话表达问话人需要对方帮忙,需要对方提供给墨水,所以尽管是疑问句,也要用some.
