Aggressive这个英文词儿可有意思了，咱们得好好唠唠：
1. 最常用的意思就是"好斗的、侵略性的"，比如说"这人特aggressive"就是说他老爱跟人干架
2. 但有时候也不全是贬义，可以表示"积极进取的"，比如"aggressive marketing strategy"就是"激进的营销策略"，这词儿得看语境
3. 医学上指"病情发展迅速的"，比如说"aggressive cancer"就是"恶性程度高的癌症"
4. 商业领域里说"aggressive growth"就是"快速扩张"，这词儿用在这儿还挺正面的
5. 体育比赛里"aggressive play"就是"进攻性打法"，跟"防守型"对着干
补充说明：这词儿在中文里得灵活处理，有时候得翻译成"强势的"，有时候得说"咄咄逼人的"，得看具体场合。比如"aggressive personality"可以翻成"强势性格"，但要是说"aggressive behavior"可能就是"攻击性行为"了。
