1     我今天很累。    2     We had a math test at school. It was very challenging. I studied a lot yesterday and stayed up very late.     3     I didn’t feel very well this morning. But I still think I did a good job in the test. I hope so! I’m afraid if I did badly, Mum and Dad may regret that     4     他们给我买了一辆这么贵的自行车。My friends say that I should not worry because I always get good marks in math,     5     but I’m still nervous about my results.
