题目

一段英文对话,
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吗?一个胃痛?胃痛可数么?
2、I had a stomachache earlier——为什么要用earlier而不是early?即,表示“我之前胃痛”为什么要用比较级?
3、you're not eating heathy foods.What have you been eating?——为什么要用进行时态（现在进行时和完成进行时）,而不是一般时态?

答案

回答如下：1 可以加 a.这里的a不是一个的意思,而是一个特定的冠词,一个固定搭配.相类似的还有 A HEADACHE,CATCH A COLD等等~2 earlier 是指之前,而early是指很早的意思,两个词语意义不一样.有时要注意,形容词的比较...
