Workload Too Demanding
We are at senior high school. Every day, we have many exercises that we can＇t complete and many books that we can＇t finish reading. The teachers continually repeat the words that we are already able to recite.
Teachers and students all work hard in order to improve the percentages① of those entering college. But the burden of work in class is so heavy that we have little time to do sports, which has left many of us in poor health. What＇s worse, many students have lost interest in their studies altogether.
It is known to all that good health is as important as knowledge. Virtues② such as bravery, discipline and love of our motherland can＇t be learned only in classes, but should also be learned through social practice. We should be given the time and opportunity to be exposed to society so we can learn what can＇t be taught from books.
We are young and we have young hearts. We love study as well as amusements. We hope that the number of exercises class will be reduced so we can take part in more after-class activities. In this way we will be able to learn much more and be more effective in our studies.

本文第一段和第二段前半部分是摆学校课业负担重的事实，谈的是原因。从第二段后半部分开始分析负担过重带来的结果。作者分析了四种结果，即负担过重会影响身体健康（poor health），会使学生失去学习兴趣（lost interest），会使学生学不到社会公德（social virtues），还会使学生失去娱乐活动（amusements）的机会。所以，本文是一因多果说明文。
