some advice对吗?some不是修饰可数名词吗,advice是不可数名词呀?

some advice的用法是对的
some 的后面可以跟可数名词也可以跟不可数名词，
如：
some跟可数名词：some apples;some oranges
some跟不可数名词:some fish;some water

可以的,以为some 有表示某个...的意思
如some one表示某个人

牛津高阶英汉双解词典
some
(used with [U] ns 与不可数名词连用) an unspecified amount of 一些; 若干:
There's some ice in the fridge.冰箱里有些冰块儿.
Some mail came for you this morning.今天上午有你的邮件.
You left some money on the table.你把钱落在桌子上了.
(used with pl [C] ns,usu referring to three or more 与复数可数名词连用,通常指三个或三个以上) an unspecified number of 一些; 若干:
Some children were playing in the park.有些小孩儿在公园里玩儿.
Why don't you give her some flowers?何不送给她一些花?
我删了一些多余的部分.这样比较清晰了.
根据some与不可数名词可以连用.所以some advice 是正确的

some有“某个，某些”的意思。这样翻译就是“某些意见”
