假设最近你班同学针对是否有必要上培训课进行了一次讨论.请根据下面的中文提示,用英语写一篇短文介绍这次讨论内容.

Recently we had a heated discussion on whether a training class for students is necessary or not in our class. Some students are favor of it because they think attending a training class is a great way to study with a teacher and students can not only review what they have learned in school but also get some additional knowledge. Others don’t think so because they don’t think a training class can help the students master knowledge. Also, they think students need to have a good rest after school. In my opinion, it is necessary for those who are weak in a certain subject to attend a training class .
