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、

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、
