一段英文對(duì)話,
A:What's the matter?
B:I had a stomachache earlier.I think I ate too much.
A:Really?Or maybe you're not eating heathy foods.What have you been eating?
B:I have been eating a lot of meat.
1、stomachache前面可以加a嗎?一個(gè)胃痛?胃痛可數(shù)么?
2、I had a stomachache earlier——為什么要用earlier而不是early?即,表示“我之前胃痛”為什么要用比較級(jí)?
3、you're not eating heathy foods.What have you been eating?——為什么要用進(jìn)行時(shí)態(tài)（現(xiàn)在進(jìn)行時(shí)和完成進(jìn)行時(shí)）,而不是一般時(shí)態(tài)?
