    小知识

    When you can't keep up with your fellow marathon runners, you can say that you lag behind them.

    The word lag describes a kind of slowness or delay. As a noun, it means a slowing: “The coach was disappointed by the lag in her swimmers' best times that day.” When you lag behind someone, you fall back or don't measure up. A student who struggles with math, for example, might say that his grades lag behind his best friend's. In the 1550s, lag meant “last person.”

    单词用法

    动词辨析
    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。
