求一篇关于介绍耳机的英语作文中学生作文一两百字左右！！！！！

Nowadays many students listen to music and learn English with earphones. As for your trouble with ears and bad memory, I’m afraid you spend too much time listening with earphones. In fact, listening to music while doing your lessons may result in less concentration on your study. Besides, the overuse of earphones does harm to your hearing. There are many ways we can enjoy music and learn English. For instance, a recorder or a radio may be a good choice. However, if you do need to use an earphone, you should rest your ears for at least ten minutes every hour but do not use it more than 2 hours a day. I hope things will get better soon.
