It worked
有效

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?"

Tom早上老起不來，所以上班總是遲到?！∷睦习宸浅Ｉ鷼?，警告他如果他不能有所改善的話就炒他的魷魚。于是，Tom去看醫(yī)生，醫(yī)生給了他一顆藥丸并告訴他要在睡覺前服下這顆藥。Tom照醫(yī)生的話做了，睡得非常之好，事實上，他在早上鬧鐘響之前就起來了。Tom從容不迫地吃完早餐，然后興高采烈地開車上班去了。
“老板”，Tom說，“那藥真管用，我的睡眠好極了！”
“是夠管用的，”老板說，“問題是，昨天你人哪去了”？
