There are times when people are so tired that they fall asleep almost anywhere. We can see there is a lot of sleeping on the bus or train on the 1 home from work in the evenings. A man will be 2 the newspaper, and seconds later it 3 as if he is trying to eat it. Or he will fall asleep on the shoulder of the stranger 4 next to him. Another place where unplanned short sleep goes on is in the lecture hall in the campus where a student will start snoring(打鼾)so 5 that the professor has to ask another student to 6 the sleeper awake.
