Most people work or study from Monday to Friday．The weekend is usually a time of rest．But today’s Chinese teenagers can hardly rest during the weekends．
According to a survey, 24％ of the Grade 8 students in Beijing have classes at the weekend．Over 40％ of the middle school students have less than eight hours’ sleep each night because of study．
And this doesn’t happen only in Beijing．Ji Chunying is a Grade 9 student in Guangzhou．The 14-year-old girl has to get up at 6∶45am on Saturday．Then she has classes all the day．On Sunday, she goes to extra(额外)classes for math and physics．But Ji doesn’t complain．She says her classmates all work very hard．
Finding time to have fun
Zhao Ming, 13, is from Zhanjiang, Guangdong．Zhao’s weekend is less busy．But he still spends Saturday in school．On Sunday, after finishing homework, he plays basketball．“I feel happy because I still have time to do the things I like,”he said．Some students are much luckier．Ding Yi, a Grade 8 student from Laiwu, Shandong, is one of them．During the weekend, Ding usually gets up at 8∶00am．Then she spends some time doing homework．After that she is free to go shopping or watch TV．“My teacher said I don't need to push myself too much．Learning well at school is enough,”Ding said．“I feel pretty lucky．”

Do you know something about tree rings(年轮)? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?
A tree will grow well in a climate(气候)with lots of sunshine and rainfall．And little sunshine or rainfall will limit(限制)the growth of climate by studying the tree rings．For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside．If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year．If it is near to the eleventh ring, then the climate that year was bad．
Tree rings are important not only for studying the history of weather but also for studying the history of man．Many centuries ago there lived a lot of people at a place in New Mexico．But now you can find only sand there－no trees and no people．What happened?
A scientist studied the rings of dead trees there．He found that the people had to leave because they had cut down all the trees to make fires and buildings．As all the trees had gone, the people there had to move．
