(2018·陕西咸阳高三模拟)No one can doubt the fact that education plays an important role in a person\'s life. However, different people prefer different ways of education. Recently, a survey in Canada found that about 40 percent of high school students are not in favor of daily homework, which quickly led to a heated discussion about whether daily homework should be ended or not in schools.
Some people insist that daily homework helps students a lot. Yet others are for the opinion that homework is nothing more than a routine activity that cuts time for leisure or physical exercise. It\'s true that
out-of-class activities should be valued in a student\'s development, but from my point of view, homework still plays an important role in one\'s life.
Doing daily homework is a way to build a foundation for a person\'s self-development. In the long run, student\'s study habits will be more developed and their awareness of the importance of learning will be raised by doing homework every day. An experiment carried out by the University of British Columbia found that former students who did homework every day still take part in self-study every day even though they have already graduated. Homework also helped give them a deeper understanding of how important education is in a person\'s life.
Students doing homework every day also have better time management skills, since daily academic exercises can help them plan their free time more effectively. Take me as an example, I spent a lot of time playing video games when I was in primary school when there was little homework to do. After I got to middle school, the time I spent on homework began to increase greatly. But it did not become a burden for me. Instead, it helped get rid of my gaming habit as well as improve my ability to manage time.
Doing homework not only develops students\' good habits and knowledge, but also improves their ability to manage their spare time. Although doing daily homework isn\'t ideal for everyone, people have to admit that the advantages it brings are more valuable than the harm.
