还得问几个问题，不好意思

我就是猪头

1.

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

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

But you did over your cough a lot faster.是什么意思？

2. 什么是treading course ？

3. 什么是take tickets? 查票？

4. They will refund you all the ten percent if you let them know right away. 是什么意思？refund是退10%还是90%？
