positive [ˈpɒzətɪv] adj.积极乐观的；良好的；有把握的；确信；正面的
essay [ˈeseɪ] n.短文；散文；文章
关键使用提醒
1.作动词时，comment 是不及物动词，后面接宾语必须加介词 on 或 upon，不能直接说 “comment the issue”，正确表达是 “comment on the issue”。
2.“no comment” 是固定搭配，多用于新闻采访或正式场合，表示 “不发表意见”，注意 “comment” 不用复数。
3.初中写作高频场景：描述对书籍、电影、事件的看法时，用 “make a comment on” 或 “comment that” 能让表达更丰富。
比如 “我对这部电影的评论是它很感人”→ “I commented that the movie was very moving.”
