我想问
1)i would like (some) coffee 为什么是用(some )可以说成 i would like a coffee 吗?如果不行的话...为什么有些句子却可以 比如说:i would like a sandwich
2)到餐馆时,如果我想要点一份早餐,怎么说
是can i have a (one) breakfast 需要加one吗?
或i would like a breakfast
还是i want a breakfast,i'll have a breakfast
3)is he Chinese 还是was he chinese 是要用过去式还是现代式
各位请纠正我,谢谢师父们
