　　This happens to students in America．Now it’s time to start a homework revolution(变革)．

　　Do students in the United States receive too much homework? According to the National Education Association, a student should be assigned(布置)no more than 10 minutes per grade level per night．For example, a first grader should only have 10 minutes of homework, a(B)grader, 20 minutes, and so on．This means that a student in my grade－seventh－should have no more than 70 minutes of work(C)each night．Yet this is often doubled, sometimes even worse!

　　It’s no good giving students too much homework．According to research, kids are developing more illness at school, such as stomachaches, headaches and sleep problems than before．

　　Some people have different ideas, saying that homework prepares kids for doing better in high school, better in college, and(F)今后找到更好的工作．But too much homework is sapping students’ strength, curiosity(削弱学生的个性和好奇心), and most importantly, their love of learning, is that really what teachers and parents want?
