Ⅳ.阅读理解

The most frightening words in the English language are, “Our computer is down.”

You hear it more and more as you go about trying to conduct your business.

The other day I was at the airport attempting to buy a ticket to Washington and

the attendant said, “I'm sorry; I can't sell you a ticket. Our computer is down.”

“What do you mean your computer is down? Is it depressed？”

“No, it can't be depressed. That's why it's down.”

“So 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

drinking coffee and 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. Sometimes it's down for 10 minutes, sometimes for two hours.

There's no way we can find out without asking the computer, and since it's down,

it won't answer us.”

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 couldn't tell without asking the computer.”

“Maybe I could just go to the gate and ask the pilot if he's flying to

Washington，” I suggested.

“I wouldn't know what gate to send you to. Even if the pilot was going to

Washington, he couldn't take you if you didn't have a ticket.”

“Is there any other airline flying to Washington within the next few hours？”
