Passage Two

One day I was at the airport waiting for a ticket to New York and the girl in the ticket office said, "I'm sorry, I can't sell you a ticket. Our computer is down."

"If your computer is down, just write me out a ticket."

"I can't write you out a ticket. The computer is the only one allowed to do so."

I looked down on the computer and every passenger was just standing there staring at the black screen. Then I asked her, "What do all you people do?'

"We give the computer the information about your trip, and then it tells us whether you can fly with us or not."

"So when it goes down, you go down with it."

"That's good, sir. '

"How long will the computer be down?" I wanted to know.

"I have no idea. There's no way we can find out without asking the computer."

After the girl told me they had no backup (备用) computer, I said. "Let's forget the computer. What about your planes? They're still flying, aren't they?"

"I wouldn't know," she said, pointing at the dark screen. "Only 'IT'knows. 'It'can't tell me.

By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people started to cry and still others kicked their luggage.
