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.”

New words：
eliminate[ɪˈlɪmɪˌneɪt] v.消除；消灭；清除；淘汰
词源拆解：
源自拉丁语 “eliminatus”。
由前缀 e-（出、离开） + 词根 “limen”（门槛） + 后缀 “-ate”（动词后缀）构成。
字面意思是 “跨出门槛、排除在外”
核心语义围绕“彻底去除不需要的事物”或“在竞争中淘汰对手”展开。

gender discrimination 性别歧视

关键使用提醒
1.区分 gender 和 sex：日常交流中两者都可表示 “性别”，但 sex 更侧重生理差异（如医学报告），gender 更侧重社会文化层面的性别认同（如性别平等）。
2.写作高频短语 gender equality 和 gender discrimination 可以直接套用，比如 “反对性别歧视”→ “oppose gender discrimination”。
