常见误用提醒

使用 profitless:This project is profitless for me to do. → This project is profitless for me. (错误用法中 'to do' 冗余,因为 'profitless' 已直接描述项目性质,正确用法应简洁表达。)

使用 profitless:He felt profitless after the failure. → He felt that the effort was profitless after the failure. (错误用法将 'profitless' 误用于描述人的感受,它应修饰事物如努力或活动,正确用法需明确主语。)

使用 profit:I profit a lot from this book. → I profited a lot from this book. (profit 作为动词时,在一般过去时或完成时中需要变化形式,这里应用过去式 profited 表示已发生的获益。)
