How important is homework? According to the Los Angeles Unified School District(LAUSD), it’s not that important! The district has made a big change for the 2011-2012 school year. It started on July 1, homework counts for only 10% of a student’s grade. The district, the second largest in the country, says its new way can provide a fairer assessment(评定) of students’ homework and achievements.
The district hopes students only need to spend less time on homework and more time on hobbies and with their families. By reducing the weight of homework toward a student’s grade, a truer picture of the student’s knowledge will be shown in the achievement grade.
However, it doesn’t mean the students can throw out homework. It says that homework is a chance for students to practice their skills and a tool for students to prepare for coming lessons. Still, LAUSD is joining a growing list of schools that have controlled the amount of homework.
How much time children should spend on homework is a hot topic. Harris Cooper, a professor at a university, says that the proper amount of homework time is ten minutes a day multiplied by(乘以) the student’s grade. This means a third grader should spend 30 minutes a day on homework. And a sixth grader would spend 60 minutes. “Good homework in the proper amount will have better effects on them,” he said. “Bad homework or too much homework will have worse effects.”
But some people think homework is an important part of learning. They say many children just won’t try their best if homework doesn’t count toward their grade. Some teachers also think homework is important. They argue that students who do their homework perform better on tests and in school than those who do not. They are afraid that the new way will encourage students to pay less attention to homework.

The bell for class rang. All the students took out their 46 , waiting for the teacher. Our Chinese teacher, Miss Liu, had told us before that we were going to write a composition   47 class.
A minute passed, and another, 48 the teacher didn't appear. We began to wonder what was the matter with her. Was she ill? Or had she forgotten about the class? 49 could tell. Soon some students began to study other subjects, some students began to talk and even made   50 .
About ten minutes later, the door opened and Miss Liu 51 came in, smiling. She didn't say sorry to the class. We felt 52 angry. The teacher often told us never to be late for class and said it was 53 manners to be late. She also said that if we were late, we should make an apology (道歉) 54 at once or after class. But now she was late and had kept the whole class waiting for such a long time and didn't even tell us the reason. It was unfair. At this moment, Miss Liu picked up a piece of chalk(粉笔) and   55    "Teacher IsLate" on the blackboard and said that was the topic of our composition today. All of us smiled and understood what the teacher meant.
