My classmates are doing a good job of their plans: some students intend to travel, they want to go to Beijing, the West Lake, Mountain and so on; other students plan to read more books at home, in order to prepare for future study; there are some students prepare physical exercise, and maintain good health.
I have to spare time to help my parents to do some household chores, studying the original knowledge. I believe that my summer vacation will be very substantial.
