sticking-plaster可不可数?

sticking-plaster是不可数的
例如
Then she put some sticking-plaster round his finger.
have some breakfast 可以这样用的
例如
Mother:Well,at least have some breakfast before you go.
妈妈：至少在走之前吃点早饭吧.
We almost forget to have breakfast.Some one is selling hotdogs nearby,let's go get some!
光顾着玩了,大家都忘记了自己还没有吃早餐,正好旁边有买热狗的,赶快买几个填填肚子!
可以加定冠词 the 和补丁冠词 a的
例如
They have already had the breakfast before they got to the hotel.
在他们到达旅店之前已经吃过早饭了.
We have a breakfast buffet.
我们有自助早餐供应.

这是美语AmE。英语BrE就直接是plaster。不可数。
但要表达很多的时候，通常可以加s。跟fish这类词差不多。
