medicine可数吗?
medicine 表示“药”,尤指内服药,通常为不可数名词。如:
Don't take too much medicine. 药不要吃得太多。
The cough will pass away without medicine. 这种咳嗽不服药也会好的。
但指不同种类时,可用作可数名词。如:
Keep those medicines out of reach of the children. 把那些药放在孩子够不着的地方。
She has taken a lot of different medicines, but none have cured her disease. 她已服用了许多药,但没有一种药能治好她的药。
