有几个PP2上的听力SCRIPT不懂意思，请各位大侠指教。

M：I don’t know I am going to get these done tonight. I’ve got two chapter history to read and thirty calculus problems to finish for tomorrow, and boy, do I have trouble with calculus?

F:  Well, you know it’s usually best to get the hardest work done first。

这里M作后一句是什么意思？

2、

M: I have two classes this afternoon and then I have to work tonight. And I feel miserable. Do you have any cold medicine?

F: Sure. I ‘ve got a bottle you could have. But you did over your cold a lot faster. Maybe just take it easy for a few days.

But you did over your cold a lot faster这句是什么意思？

3、

At this rate, I don’t think I am ever going to get better on writing. My composition mark has been the same all semester. Straight C.

What did your instructor say keeping your marks down?

What did your instructor say keeping your marks down是什么意思？

不好意思，问题有点多。谢谢。

M的最后一句话，象我们也经常说的，有点自嘲的意味，就是“天哪，我是不是对计算有困难呀。。”

意思就是说你确实恢复的挺快的了，不需要多吃药，休息几天就好了。。

上文说一直是C，所以才会问“那你的指导老师对一直把你的分数给的这么低怎么说。。”

建议下次提问的时候可以单题分开发贴，方便大家讨论回答。。呵呵

好运！
