I climbed the stairs slowly，carrying a big suitcase，my father following with two more. By the time I got to the third floor，I was　1　and at the same time feeling lonely. Worse still，Dad　2　a step and fell，sending my new suitcases 　3　down the stairs. “Damn!”he screamed，his face turning red. I knew trouble was ahead. Whenever Dad's face turns red，　4　！
How could I ever　5　him to finish unloading the car without screaming at me and making a scene in front of the other girls，girls I would have to spend the rest of the  6  with？Doors were opening and faces peering out(探出)，as Dad walked with difficulty close behind. I felt it in my bones that my college life was getting off to a(n)　7　start.
“Enter the room quickly，”I thought. “Get him into a chair and calmed down.” But then again，would there be a chair in Room 316？Or would it be a(n)　8　room？

It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about Al Herpin. Al Herpin, it was said, never slept. Could this be true ? The doctors decided to see this strange man themselves.

Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day. They never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.

The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They found only one answer that might explain his condition. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason ? No one could be sure. Herpin died at the age of 94.
