听力原文：Are you afraid to raise your hand in class, even when you know the answer？ If you are, most people would say that you're shy.
If you feel shy, you're not alone. Nine out of ten people are at least a little shy. But however shy you are, scientific evidence seems to show that it isn't your fault. You may have been born that way.
How do psychologists measure shyness？ One way is by observation. They keep detailed records of people's actions—like how often these people speak to others, or how long it takes someone to say hello to a stranger.
Another way to measure shyness is to ask people questions. The test only takes about 10 minutes. It asks questions like "Do you like going out a lot？" and "Do you have many friends？" People must answer either yes or no. These questions can predict how people actually behave in social situations. Suppose the test tells you that someone is shy. Chances are good that that person will act shy.
When scientists measure shyness, they're really comparing degrees of shyness. In other words, when researchers say people are shy, they really mean they are more shy than others.
Why does the speaker say that it isn't a fault to be shy？

David: Can you spare a moment, dear？ I want you to listen to this letter.
Sally: Go ahead, then.
David: Dear Sir, my wife and I arrived home last night after a holiday arranged by your firm, in
Jersey. We stayed at the hotel described in your brochure as a comfortable, medium-sized hotel, with a magnificent view of the sea, offering courteous, old fashioned service and excellent food, served in a relaxed friendly atmosphere.
Sally: Yes, that's what the brochure said.
David: In fact the hotel is situated at least half a mile from the sea. Our room overlooked a car park...
Sally: Through the gates of which motor vehicles were constantly arriving or departing.
David: Yes, that's good. The food was strictly beef-burgers and chips or fish and chips. Wine was available, but at exorbitant prices, and as for the courteous, old-fashioned service, the majority of the staff were foreign and virtually incapable of speaking or understanding the English language.
Sally: Yes, that's quite true.
David: In addition to this, we were most unhappy with the arrangements for our journey home. We were instructed to catch the 11:00 am ferry...
Sally: Wasn't it 12:00？
David: No, 11:00... but this was apparently delayed and we did not get away till 6 o'clock in the evening. Now that our holiday is over, it seems fairly pointless writing this letter, but I should like you to know that we were most disappointed with the hotel and travel arrangements and shall certainly not be booking any futurc holidays through yours. Yours faithfully, David Smith.
Sally: Yes dear, that' s a very good letter.
