Tom had this problem of getting up late in the morning and was always late for work. His boss was mad at him and threatened to fire him if he didn't do something about it. So Tom went to his doctor, the doctor gave him a pill and told him to take it before he went to bed. Tom slept well, and in fact, beat the alarm in the morning. He had a leisurely breakfast and drove cheerfully to work. "Boss", he said, "The pill actually worked!" "That's all fine" said the boss, "But where were you yesterday?"汤姆早上老起不来，所以上班总是迟到。他的老板非常生气，警告他如果他不能有所改善的话就炒他的鱿鱼。于是，汤姆去看医生，医生给了他一颗药丸并告诉他要在睡觉前服下这颗药。汤姆照医生的话做了，睡得非常之好，事实上，他在早上闹钟响之前就起来了。汤姆从容不迫地吃完早餐，然后兴高采烈地开车上班去了。 “老板”，汤姆说，“那药真管用，我的睡眠好极了！” “是够管用的，”老板说，“问题是，昨天你人哪去了”？
