Our class made a survey, " don't let your worries. " About fifty percent of the students in our class are worried about their homework and Research ( academic ). And they feel overly stressed. About thirty percent of the students think that their parents and they were very strict. They usually do not follow their parents. The other twenty percent said they would be weak health. They complain that, they have little time for their hobbies or sports. So I hope our teacher will give us less homework.
