求翻译：你应该在课上参与小组讨论，表达自己的想法，也可以在课间和同学交谈。在日常生活中，我认为你可以主动问候同学，对同学友好，帮助同学等。同时你也需要积极参加班级活动，例如参加运动会，歌咏比赛等。以上便是我的建意。是什么意思？

You should participate in group discussions in class, express their ideas, or to talk to the class and students. In daily life, I think you can proactively greet students, friendly to students, helping students. At the same time you also need to actively participate in class activities, such as games, singing contest, and so on. Above is what I built.
