常见误用提醒

使用 unhealthy:He is unhealthy because he eats too much. → He is unhealthy because he eats too much unhealthy food. (错误用法中“eats too much”不够具体,正确用法应明确“unhealthy food”以强调不健康饮食。)

使用 unhealthy:This habit is unhealthy for me. → This habit is unhealthy for my health. (错误用法中“for me”可能泛指,正确用法用“for my health”更准确描述对健康的影响。)

使用 healthy:I am health. → I am healthy. (health 是名词,不能直接作表语;healthy 是形容词,应使用 healthy 来描述状态。)
