词义辨析

v. (动词)

lag, dawdle, delay, loiter, procrastinate

• 这组词都可表示因行动或动作缓慢而使进步受阻或工作没有完成。它们之间的区别是:delay常指拖延某事(如出发、完成必要的工作等); procrastinate常指因懒惰、匆忙、冷淡或拖拉的习惯造成耽搁; lag主要指不能保持应有的速度去达到某个目的; loiter主要指进行中或完成工作时的耽搁,也可指因闲逛而落后; dawdle语义比loiter稍弱,侧重闲散、思想不集中而多花时间或浪费时间。例如:
• He procrastinated in making an appointment to see his doctor.他迟迟不与他的医生预约看病。
• The small boy soon became tired and lagged far behind.这小男孩一会儿就累了,远远地落到了后面。
• We don't increase our earnings by loitering over our work.我们靠磨洋工是不会增加收入的。
• Ade dawdled all the way to school.艾德在上学途中磨磨蹭蹭的。

词源解说
