本文从“阐释社群”这一理论出发，对2015年底多家媒体推出的年度新闻评论评选及其颁奖辞、评论策划，以及部分知名评论员在个人微信公众号撰写的年终总结等文本展开分析，探讨评论员群体在“热点时刻”的阐释实践：他们是如何理解评论空间与言论表达之间的矛盾，又是如何建构移动新媒体平台上的评论标准，以及在强化身份认同、建构评论员共同体时，使用了怎样的话语策略，又存在怎样的价值分野。

From the perspective of “interpretive community”, this study analyzes several news organizations’ annual review awards and awarding citation, comment planning, and some wellknown commentators’ summaries on their Wechat accounts by the end of 2015. The study explores commentators’ interpretive practices, aiming to figure out how they interpreted the contradiction between speech restriction and free speech, how they established review criteria on mobile media platform, and the discourse strategies they used ,the value divisions they had during strengthening identities and constructed communities.
