填空题How Deafness Makes It Easier to Hear Most people think of Beethoven's hearing loss as an obstacle to composing music. However, he produced his most powerful works in the last decade of his life when he was completely deaf. This is one of the most glorious cases of the triumph of will over adversity, but his biographer, Maynard Solomon, takes a different view. (1) . In his deaf world Beethoven could experiment, free from the sounds of the outside world, free to create new forms and harmonies. Hearing loss does not seem to affect the musical ability of musicians who become deaf. They continue to "hear" music with as much, or greater, accuracy than if they were actually hearing it being played. (2) . He described a fascinating phenomenon that happened within three months: "my former musical experiences began to play back to me. I couldn't differentiate between what I heard and real hearing. After many years, it is still rewarding to listen to these playbacks, to 'hear' music which is new to me and to find many quiet accompaniments for all of my moods. " How is it that the world we see, touch, hear, and smell is both "out there" and at the same time within us? There is no better example of this connection between external stimulus and internal perception than the cochlear implant. (3) . However, it might be possible to use the brain's remarkable power to make sense of the electrical signals the implant produces. When Michael Edgar first "switched on" his cochlear implant, the sounds he heard were not at all clear. Gradually, with much hard work, he began to identify everyday sounds. For example, " The insistent ringing of the telephone became clear almost at once. The primary purpose of the implant is to allow communication with others. When people spoke to Eagar, he heard their voices "coming through like a long-distance telephone call on a poor connection. " But when it came to his beloved music, the implant was of no help. (4) . He said, " l play the piano as I used to and hear it in my head at the same time. The movement of my fingers and the feel of the keys give added ' clarity' to hearing in my head. " Cochlear implants allow the deaf to hear again in a way that is not perfect, but which can change their lives. (5) . Even the most amazing cochlear implants would have been useless to Beethoven as he composed his Ninth Symphony at the end of his life. A. No man-made device could replace the ability to hear. B. When he wanted to appreciate music, Eagar played the piano. C. Still, as Michael Eagar discovered, when it comes to musical harmonies, hearing is irrelevant. D. Michael Eagar, who died in 2003, became deaf at the age of 21. E. Beethoven produced his most wonderful works after he became deaf. F. Solomon argues that Beethoven's deafness "heightened" his achievement as a composer.

填空题 (46) . If there is one which I take leave to doubt then it is older people who create it, not the young themselves. Let us get down to fundamentals and agree that the young are after all human beings people just like their elders. (47) : the young man has a glorious future before him and the old one has a splendid future behind him: and maybe that is where the rub is. When I was a teenager, I felt that I was just young and uncertain that I was a new boy in a huge school, (48) . For one thing, being a problem gives you a certain identity, and that is one of the things the young are busily engaged in seeking. (49) .They have an air of freedom, and they have not a dreary commitment to mean ambitions or love of comfort. They are not anxious social climbers, and they have no devotion to material things. All this seems to me to link them with life, and the origins of things. It's as if they were in some sense cosmic beings in violent and lovely contrast with us suburban creatures. All that is in my mind when I meet a young person. He may be conceited, ill-mannered, presumptuous or fatuous, but ! do not turn for protection to dreary cliches about respect for elders as if mere age were a reason for respect. I accept that we are equals, (50) .A. There is only one difference between an old man and a young one.B. People are always talking about "the problem of youth".C. and I will argue with him as an equal, if I think he is wrongD. and I would have been very pleased to be regarded as something so interesting as a problem.E. I find young people exciting.F. It is very enjoyable to teach young children.

填空题U. S. European Drug Officials Approve Inhaled Insulin A. form of insulin for people with diabetes to take by mouth is expected to be sold within a few months. The new medicine is called Exubera. The United States Food and Drug Administration and the European Commission both recently approved it for adults. It could make life easier for many diabetics who require daily injections of insulin to control their blood sugar levels. But it will not replace all insulin injections. And it is not for everyone. People who smoke or have stopped smoking for less than six months should not take Exubera. (1) Three drug companies — Pfizer, Sanofi-Aventis and Nektar Therapeutics — developed the inhaled insulin. (2) Experts say about fifteen percent of diabetics who need insulin do not take it. The treatment can involve several injections each day. Insulin is a hormone that the body uses to change food into energy. Failure to control blood sugar levels can lead to serious problems, including blindness and loss of blood flow to the feet. It can also lead to heart disease, stroke and kidney failure. Insulin has been sold as a drug since the nineteen twenties. This is the first new way to take it. Exubera uses a powder breathed into the lungs through a mouthpiece. Pfizer will study the long-term effects. It says some patients have reported a mild cough while using the inhaled insulin. (3) Many people do not know they have diabetes. There are two forms. Most diabetics have the Type Two form. Their body does not make enough insulin or cannot effectively use the insulin it produces. (4) Most Type Two diabetics do not take insulin. Their medicines can be taken by mouth. Diet, exercise and weight control are also important. Type One diabetes often begins in childhood. (5) Officials say diabetics with either type could use inhaled insulin, either before or after a meal. But Type One diabetics and some with Type Two would still need a longer-lasting injection at least once a day. A. With this type the body is unable to produce insulin. B. Pfizer recently bought the rights to sell it worldwide. C. The control of their blood sugar levels is most important for patients with diabetes. D. It is common in people who are overweight and not active. E. Some patients with lung disease should not take it either. F. People are advised to have their lungs examined before using Exubera, and at least once a year after that.

填空题The Dangers of Second-hand Smoke Most people know that cigarette smoking is harmful to their health. Scientific research shows that it causes many kinds of diseases. In fact, many people who smoke get lung cancer. However, Edward Gilson has lung cancer, and he has never smoked cigarettes. He lives with his wife, Evelyn, who has smoked about a pack of cigarettes a day throughout their marriage. 1 No one knows for sure why Mr. Gilson has lung cancer. Nevertheless, doctors believe that second-hand smoke may cause lung cancer in people who do not smoke because nonsmokers often breathe in the smoke from other people"s cigarettes. 2 The U. S. Environmental Protection Agency reports that about 53,000 people die in the United States each year as a result of exposure to second-hand smoke. The smoke that comes from a lit cigarette contains many different poisonous chemicals. In the past, scientists did not think that these chemicals could harm a nonsmoker"s health. 3 They discovered that even nonsmokers had unhealthy amounts of these toxic (有毒的) chemicals in their bodies. As a matter of fact, almost all of us breathe tobacco smoke at times, whether we realize it or not. For example, we cannot avoid second-hand smoke in restaurants, hotels and other public places. Even though many public places have nonsmoking areas, smoke flows in from the areas where smoking is permitted. It is even harder for children to avoid second-hand smoke. 4 Research shows that children who are exposed to second-hand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as are children of nonsmokers. The risk is even higher for children who live in homes where both parents smoke. People are becoming very aware of the dangers of second-hand smoke. 5 A. Recently, though, scientists changed their opinion after they studied a large group of nonsmokers. B. The Gilsons have been married for 35 years. C. This smoke is called second-hand smoke. D. However, second-hand smoke is dangerous to all people, old or young. E. As a result, they have passed laws which prohibit people from smoking in many public places. F. In the United States, nine million children under the age of five live in homes with at least one smoker.

填空题The Story of Lani Five-year-old Lani still takes seven medicines with her breakfast every morning. "She"s very good about it," says her father David. Lani is alive today because of her father David, in more than one way; when she was one year old she received part of her father"s liver in a liver transplant operation. Lani was born with a liver illness. 1 Doctors advised that a transplant was the only way in which she would live. The operation lasted 12 hours and needed two teams, one for the father and one for the daughter. 2 In these cases, the donor"s liver grows to normal size in about eight weeks. And the child"s liver becomes smaller. Lani spent three weeks in hospital after the operation. Because the receiver"s body tries to reject the new organ, the patient has to be given special drugs. 3 Although David left hospital after 10 days, he didn"t return to work until after three months. In order to reach the liver, the doctors have to cut through the stomach wall, which is strong and full of muscle. It therefore takes a long time to recover after this operation. 4 So far, only 16 of these liver-transplant operations have been carried out in Britain. 5 Doctors say, "If possible, we prefer to take a liver from a dead donor, usually a parent." Lani still has to look after her health, and she gets more tired than other children of the same age, but doctors hope that she will continue to get stronger and stronger. A. She had one operation when she was six weeks old, which was not successful. B. While these drugs are given, it is important that the patient does not catch any illness, not even a cold. C. In this operation a piece of liver, weighing about 250—300 grams, was removed from the father and transplanted into the daughter. D. David quickly recovered from the operation. E. However, they are more common in North America and Japan. F. David was finally able to ride his bike again after about a year.

填空题The Drink Your Body Needs Most 1. Our bodies are estimated to be about 60% to 70% water. Blood is mostly water. And our muscles, lungs, and brain all contain a lot of water. Water is needed to regulate body temperature and to provide the means for nutrients (滋养物) to travel to all our organs. Water also transports oxygen to our cells, removes waste, and protects our joints and organs. 2. We lose water through urination (排尿), respiration (呼吸) , and by sweating. If you are very active, you lose more water than if you do not take much exercise. Symptoms of mild dehydration (脱水) include chronic pains in joints and muscles, lower back pain, headaches, and constipation (便秘). A strong smell to your urine, along with a yellow color indicates that you are not getting enough water. Thirst is all obvious sign of dehydration and in fact, you need water long before you feel thirsty. 3. A good rule of thumb (好的做法) is to take your body weight in pounds and divide that number in half. That gives you the number of ounces (盎司) of water per day that you need. For example, if you weigh 160 pounds, you should drink at least 80 ounces of water per day. If you exercise you should drink another 8-ounce glass of water for every 20 minutes you are active. If you drink coffee or alcohol, you should add at least an equal amount of water. When you are traveling on an airplane, it is good to have 8 ounces of water for every hour you are on board the plane. 4. It may be difficult to drink enough water on a busy day. Be sure you have water handy at all times by keeping a bottle for water with you when you are working, traveling, or exercising. If you get bored with plain water, add a bit of lemon for a touch of flavor. There are some brands of flavored water available, but some of them have sugar or artificial sweeteners that you don"t need.

填空题______ In the first place, Britain had the money necessary to finance the larger enterprises. England's supremacy on the seas had encouraged commerce, and Englishmen had been amassing wealth through there commerce and industry. The newly rich class in that country were not the aristocratic (贵族) group, but merchants and businessmen who were willing to devote themselves to industry and scientific agriculture.

填空题Electromagnetic Energy 1. White light seems to be a combination of all colors. The energy that comes from a source of light is not limited to the kind of energy you can see. Heat is given off by a flame or an electric light. On a cloudy day it is possible to get a sunburn even though you feel cool. Visible light and the kinds of energy that produce warmth and sunburn are examples of electromagnetic energy. 2. The sun is 93 million miles from the earth. Yet we can use energy from the sun because electromagnetic energy travels through space. 3. Many other kinds of energy are also types of electromagnetic energy. Radio, television, and radar signals travel from transmitters to receivers as low-energy electromagnetic waves. Infrared(红外线的)radiation is an electromagnetic wave. When it is absorbed by matter, heat is produced. Waves of infrared and visible light have more energy than waves of radio, television, or radar. Ultraviolet rays(紫外线)and X-rays are electromagnetic waves with even greater amounts of energy. Infrared radiation is used in cooking food and heating buildings. Sunlight and electric lights are part of our requirements for normal living. Ultraviolet radiation is useful in killing certain disease organisms. X-rays and gamma rays have so much energy that they travel right through solid objects. They can be used to detect and treat cancer. X-rays are used in industry to find hidden cracks in metal, and in medicine to reveal broken bones. 4. Usually we use electricity to generate electromagnetic energy. The source of most of our energy is the sun. Heat from the sun causes water to evaporate. When the water falls to the earth as rain, some of it is trapped behind dams and then used to operate electric generators. Other generators are powered by coal, but the energy stored in coal came from the sun, too. 5. Until recently, the source of the tremendous amount of energy given off by the sun was a puzzle. If the sun depended on chemical reactions, it would have used up all its energy long ago. Experiments with electromagnetic radiation led to the theory that mass can be converted into energy. About forty years after the theory was proposed, nuclear energy was harnessed(利用)by man. Chemical energy comes from electron(电子) rearrangement. Nuclear energy comes from a change in the nucleus of an atom. Compared with chemical reactions, nuclear reactions release millions of times more energy per pound of fuel. We now believe that the sun"s energy comes from the nuclear reactions in which hydrogen is changed into helium(氦). 6. Nuclear energy is beginning to compete with coal as an economical source of power to generate electricity. It is also being used to operate engines in large ships. Scientists continue to seek new and better methods of obtaining and using energy.
