最近你的朋友Tom在他的微博上发了这样一个帖子:
These days, I feel my school life is very boring. Every day I do the same things—taking lessons, doing exercises and taking exams. Every day I take the same way—classroom, playground and dining hall. Every day the teachers say the same thing to us: Study hard and try to enter a better high school. . .
I want to make my school life easier and more colorful. What should I do?
