But why do we like it so much? It's not enough to answer: 'Because it tastes nicE.' So do other foods. But do you know any other food which some people have to keep closed until their guests arrive? They know that if they open the chocolate on their own, they'll probably go on eating until they feel slightly ill. And it isn't just the sugar that people likE.In the 17th century, when chocolate first arrived here as a drink, people did not put sugar in it because sugar was too expensivE.

听力原文：W: We all have drawers full of snapshots but what are they? A piece of history, a record of happy memories or a testament to the fact that the camera can indeed lie? Gerald is one of the editors of a book called The History of Domestic Photography. Gerald, as an art form, photography is really only just over a century olD.How has it developed in domestic use?M: Well, It's developed by being all of those things that you mentioned really. People are looking for pictures that will record their families and their homes and so the photographic technology has got closer and closer to the home—more and more informal. So if you look at the early pictures in people's albums—those taken when grandmother was a girl—in everybody's albums you'll find these very stiff, posed portraits, some of them studio portraits, and then you look at contemporary pictures today, you know, you find the family at play, you find snapshots which show children laughing, you find the holiday pictures, so it's changed over the years, become more relaxed, less of an ordeal.W: Gerald, is there a conflict, as there is in other artistic areas, between the low art of the domestic photographer and the high art of the professional?M: No, there's no conflict. I, as a professional photographer, don't take any family snaps because my children would never pose for me as a photographer at all. And if it hadn't been for my wife with her instamatic camera taking pictures, I wouldn't have any record at all of their younger years. I detect a sort of use now more by women using very easy-to-use, throw-away cameras almost, and certainly in my family it seems to be the women who are taking the pictures rather than the men.W: As you say, all the photographic companies, all the Kodak ads are directed at women. You know the kind of thing, even a woman can do this very simple photography. Taking pictures couldn't be easier these days. What about these ones then that you've got here? You've actually brought pictures that your wife has taken.M: Yes, these are not great photographs, but they are very important memories for me and they will be for my children—though they won't thank my wife for taking some of these poses. But it's interesting what you can do. The page here is a series of little cut-outs that my wife took. There are maybe twenty pictures here and they haven't all got great backgrounds. I mean, you were asking the difference between amateur and professional photography. Professional photography will have good backgrounds. Ruth would just go round and take pictures because they were good little fun moments and what she's done is cut out the best bits of it. She's got rid of, you know, the annoying chair in the background or whatever and just made one picture out of twenty bits of picturE.W: But they're all lovely, smiling, oh, not that you haven't got lovely, smiling children, but does the camera in a way tell us lies about ourselves?M: You're right. People do play up to the camera and this is the greatest problem. Among this lot here, there aren't any pictures of children looking bad tempereD.We do react to the camerA.As soon as the camera comes out you sort of go into a pose, if you likE.Probably that's their weakness really as family snaps.W: Or is it weakness? Isn't that just what they are? I mean...M: There's something missing. There's something missing from the family album. That is, anger, bad temper, you know the foul days, the sulks.W: Thank you very much.Questions:11.According to the interview, what is the big difference between pictures of old days and contemporary pictures?12.What is the subject Gerald never photographs?13.According to the interview, what do photographic companies want people to think about taking photos?14.According to the interview, which of the following statements is NOT true about pictures taken by amateur photographers?15.What does the interviewee mean by sugA.Contemporary pictures focus more on domestic issues.B.These days, having one's photograph taken is more informal.C.In the old days, people only took pictures of their grandmothers.D.The photographic technology is more advanced nowadays.

听力原文： You may grind your teeth at night. According to a recent survey, at least 8 to 10 percent of the adult population share this malady. It's called sleep bruxism. There's a waking version, too. But the origins are different and the effects are seldom as bad as during sleep.'It's much like having a large football player standing on the tooth,' says Dr. Noshir Mehta, chairman of general dentistry at Tufts University School of Dental MedicinE.During sleep bruxism, he explained, the upper and lower teeth may come into direct contact as much as 40 minutes per hour, and with a force of about 250 pounds. You can compare that with normal circumstances, when a person's teeth make contact for about 20 minutes a day while chewing, and with only 20 to 40 pounds of pressurE.Sleep bruxism is not a disease, but a sleep disorder, the third most common one behind sleep talking and snoring. It is more prevalent in children, and its origins may be different in adults.'The exact causes are unknown,' said Dr. MehtA.He explains that in the 1960s bruxism was thought to be the body's response to 'malocclusion', or problems with how the upper and lower teeth fit together; but that theory was discredited for lack of clinical evidencE.Stress was later thought to be the cause, but this failed to explain why not everyone with sleep bruxism was stressed and not everyone with stress ground their teeth. More recent research indicates some relationship of sleep bruxism to neurochemicals, but there is still disagreement on how significant a role they play.Whatever underlying causes science may show in time, the more immediate contributing factors for sleep bruxism are better understooD.The medical literature shows that stress, smoking, alcohol, caffeine and other factors may set off or worsen the condition.So what should a grinder do? Some people tried relaxation techniques like yoga, exercise, biofeedback and hypnotherapy. Much as these may have helped their overall health, they didn't seem to kick the football player out of their beds.Right away, dentists suggest fitting the mouth with a mouth guard, a small plastic device with a price tag of $ 300. It covers some or all of the teeth to protect them against damage, but does not stop the grinding or clenching itselF.You can also get an over-the-counter version at the drugstore for $20. However, 'the over-the-counter guards are usually better than nothing,' said Dr. MehtA.They protect the teeth, but may also be more likely to induce a chewing response and increase bruxism; they can also cause irreversible damage to the arrangement of the teeth, and so should be used only temporarily.Dr. Lavigne of the Canadian Sleep Society says people who wake up with headaches or jaw pain may clench or grind their teeth, and should consult their dentist, or doctors. There, patients may be directed to try some of the techniques or others. These approaches may reduce bruxism, but since there is no known cure, only the effects can be reliably treateD.In the end, mouth guards are still the best defensE.After all, if you're going to square off against a football player every night, you need padding.Questions:16.What is sleep bruxism?17.Which of the following statements is true about sleep bruxism?18.Which of the following is NOT suggested as an immediate cause of sleep bruxism?19.The doctor suggests that the over-the-counter mouth guard can only be used occasionally.
