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 profitable:This job is very profit. → This job is very profitable. (“profit”是名词,不能直接作表语形容事物;应使用形容词“profitable”表示“有利润的”。)
