• battle

  Battle suggests a long, hard struggle and often pairs with personal challenges like illness or addiction, besides literal fighting; it is usually transitive, without a preposition.

• combat 本词

  Combat is more formal and typically pairs with large-scale, abstract problems in policy or news contexts, such as crime or trafficking, rather than personal illness.

  combat 语气更为正式，通常与犯罪、贩毒等大规模、抽象的社会问题搭配，多见于政策或新闻语境，而不用于个人疾病等情形。

  The government launched a new campaign to combat drug trafficking.

  政府发起了一项新运动来打击贩毒活动。

Battle and combat both mean to fight hard against something. Battle is stronger, for a long, hard struggle, used for personal problems like illness or addiction. Combat is more formal, common in news or policy language, for big problems like crime or drug trafficking.

battle 和 combat 在这个意义上都表示“奋力对抗某事物”，但语气和使用场合不同：battle 语气较强，常指长期而艰苦的斗争，多用于个人经历（如疾病、成瘾）或实际战斗；combat 更为正式，多见于政策或新闻语境，用来描述应对犯罪、贩毒等社会性问题。这里不比较 battle 作名词“战斗”和 combat 作名词“格斗”的用法。
