To Err Is Human
Everyone must have had at least one personal experience with a computer error by this time. Bank balances are suddenly reported to have jumped from $ 379 into the millions, appeals for charitable contributions are mailed over and over to people with crazy sounding names at your address, department stores send the wrong bills, utility companies write that they're turning everything off, that sort of thing. If you manage to get in touch with someone and complain, you then get instantaneously typed, guilty letters from the same computer, saying, "Our computer was in error, and an adjustment is being made in your account."
These are supposed to be the sheerest, blindest accidents. Mistakes are not believed to be the normal behavior. of a good machine. If things go wrong, it must be a personal, human error, the result of fingering, tampering a button getting stuck, someone hitting the wrong key. The computer, at its normal best, is infallible.
I wonder whether this can be true. After all, the whole point of computers is that they represent an extension of the human brain, vastly improved upon but nonetheless human, superhuman maybe. A good computer can think clearly and quickly enough to beat you at chess, and some of them have even been programmed to write obscure verse. They can do anything we can do, and more besides.
It is not yet known whether a computer has its own consciousness, and it would be hard to find out about this. When you walk into one of those great balls now built for the huge machines, and standing listening, it is easy to imagine that the faint, distant noise are the sound of thinking, and the turning of the spools gives them the look of wild creatures rolling their eyes in the effort to concentrate, choking with information. But real thinking, and dreaming, are other matters. On the other hand, the evidence of something like an unconscious, equivalent to ours, are all around, in every mail. As extensions of the human brain, they have been constructed the same property of error, spontaneous, uncontrolled, and rich in possibilities.
The title of the writing "To Err Is Human" implies that ______.
A.making mistakes is confined only to human beings
B.every human being cannot avoid making mistakes
C.all human beings are always making mistakes
D.every human being is born to make bad mistakes

听力原文:W: Yes, sir. Can I help you?
M: Um yes. I bought this radio-cassette player here a couple of weeks ago. Here's the receipt.
W: Ahha. That's fine. What seems to be the problem?
M: Well, it's been nothing but trouble since I bought it.
W: OK. Just let me take a note of this. Err, radio-cassette player.
M: The first thing is one of the speakers doesn't work properly. The sound is completely distorted with the radio or a tape.
W: Which one is it?
M: The right-hand one. Another problem is the left cassette player. It chews up tapes. It's completely mined two of my favorite cassettes.
W: Oh dear. The speaker and the cassette player.
M: One of the cassettes was brand new, oh, and the rewind switch doesn't work. Actually it never did.
W: OK. So there's the fight-hand speaker...the cassette player and...urn, the rewind switch. Is that it?
M: No, I'm afraid not. The aerial doesn't work properly. It's stuck.
W: Hmm, I see what you mean. The handle is broken too.
M: Yes, I'd forgotten about that. It's not very good, is it?
W: Err, no. But it's under guarantee and we can repair it. Just give me your name.
M: Jonathan Hall.
W: And phone number.
M: My home number is 67532, work is 78549.
W: 78549. And it is the, urn, 11th of February.
M: Yes. That's right.
W: OK. Mr. Hall. Here is your copy. We'll give you a ring when it's ready.

听力原文:W: Good evening, Mr. Brown, and welcome to the program.
M: Thank you!
W: I wonder if you could tell listeners more about the work you do?
M: Certainly.
W: Mr. Brown, I gather that you work for a company developing software for reading electronic books?
M: That is so.
W: Do you think there is much future in that?
M: Well, people buy music online, so why not books?
W: You have to read electronic books on a machine, don't you?
M: That is so, although of course you might be able to print them out on a printer.
W: So why should people read a book on an expensive machine when they can buy a cheap copy and carry it around with them and read it whenever they like?
M: That is an interesting point. People need time to become aware of the value of e-books.
W: Is it true that at the Frankfurt Book Fair, in 2000, there was a prize for the best books published in electronic form?
M: Yes, that is true, the prize was worth $100,000.
W: Who put up the money for the prize?
M: Err, software companies such as Microsoft and Adobe.
W: I suppose they are trying to encourage publishers to get the e-book business off the ground.
M: That's probably true.

Offices vary when it comes to dress codes. Some businesses have very high standards for their employees and set strict guidelines for office attire, while others maintain a more relaxed attitude. However, it is always important to remember that no matter what your company's attitude is regarding what you wear, you are working in a business environment and you should dress accordingly. Certain items may be more appropriate for evening wear than for a business meeting just as shorts and a T-shirt are better suited for the beach than for an office environment. Your attire should reflect both your environment and your position. A senior vice president has a different image to maintain than that of a secretary or sales assistant. Like it or not, you will be judged by your personal appearance.
This is never more apparent than on "dress-down days" when what you wear can say more about you than any business suit ever could. In fact, people will pay more attention to what you wear on dress-down days than on "business professional" days. Thus, when dressing in "business casual" clothes, try to put some flair into your wardrobe choices, recognizing that the "real" definition of business casual is to dress just one notch(等级) down from what you would normally wear on business-professional attire days.
Remember, there are boundaries between your career and your social life. You should dress one way for play and another way when you mean business. Always ask yourself where you are going and how other people will be dressed when you get there. Is the final destination the opera, the beach, or the office? Dress accordingly and you will discover the truth in the axiom(公理)that clothes make the man and the woman. When in doubt, always err on the side of dressing slightly more conservatively than the situation demands.
What is the passage mainly about?
A.What is the difference between professional and casual dress?
B.A president of a company should dress differently from a secretary or sales assistant.
C.How to dress properly in a business setting.
D.Improper dress will make a person feel uncomfortable.
A.系统故障
B.区间中继台故障
C.信道机故障
D.控制盒故障
