完形填空

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 　　4　　 it．Or he will fall asleep on the shoulder of the stranger 　　5　　 next to him．　　6　　 place where unplanned short sleep 　　7　　 is in the lecture hall where a student will start snoring(打鼾)so 　　8　　 that the professor has to ask another student to 　　9　　 the sleeper awake．A more embarrassing(尴尬)situation occurs when a student starts falling into sleep and the 　　10　　 of　the head pushes the arm off the 　　11　　, and the movement carries the 　　12　　 of the body along．The student wakes up on the floor with no 　　13　　 of getting there．The worst time to fall asleep is when 　　14　　．Police reports are full of 　　15　　 that occur when people fall into sleep and go 　　16　　 the road．If the drivers are 　　17　　, they are not seriously hurt．One woman's car, 　　18　　, went into the river．She woke up in four feet of 　　19　　 and thought it was raining．When people are really 　　10　　, nothing will stop them from falling asleep -- no matter where they are．
