some ice cream要加s吗

some ice cream不要加s，因为不可数。ice cream表示冰激凌时，是不可数名词，不用加s。ice cream既可以当可数名词，也可以当不可数名词，具体看是指抽象的冰淇淋，还是指具体一份或者两份冰淇淋。

例句

I'll buy you one if there is hot icecream.

如果有热的冰淇淋，就会给我买。

These children have made off with the whole icecream!

这些孩子们把冰淇淋全吃光了。

Don't always put away too much pie and icecream.
