Promising Results from Cancer Study A new experimental vaccine(疫苗)has shown promising results in the fight against lung cancer. In a small Texas-based study, a vaccine developed by scientists at Baylor University Medical Centre in Dallas, USA, cured lung cancer in some patients and slowed the progress of the disease in others. Researchers have reported encouraging findings from this small study. Forty-three patients suffering from lung cancer were involved in these trials. Ten of these patients were in the early stages and thirty-three in the advanced stages of the disease. They were injected with the vaccine every two weeks for three months, and were carefully monitored for three years. In three of the patients in the advanced stages of cancer, the disease disappeared and in the others, it did not spread for five to twenty-four months. However, no great difference was seen in the patients in the early stages of the illness. This new vaccine uses the patient’s own immune system. It is made specifically for each patient and is injected into the arm or leg. It stimulates(刺激)the body’s immune system, which then recognizes that the cancer cells are harmful, and attacks and destroys them. The vaccine could be effective against other forms of cancer. It offers great hope for the treatment of cancer in general, although further studies are needed before such treatment can be widely used.

Music Used As a Healing Therapy 1. Music has long been used to treat patients suffering from different problems. In 400 BC, its healing properties were documented by the ancient Greeks. More recently, in both world wars in the last century, medical workers used music therapy(疗法)with people suffering from trauma(外伤). Currently, it is used as a treatment for many diseases, such as cancer, and it has also been used with patients with long-term pain and learning disabilities. 2. There is growing evidence that music can caused physical changes to the body which can improve our health. In the Welcome Trust study, which took place over three years at the Chelsea and Westminster hospital in London, patients were asked to listen to musical performances. As a result, it was found that stress levels were significantly reduced, recovery times were improved, and fewer drugs were needed. 3. These very positive results are partly due to general well-being(良好的健康状况). It is already accepted that when people feel happy and have a positive approach to life, they are more likely to feel better and recover from disease quickly. Music increases this feeling of joy and adds to the recovery process. 4. However, not all these benefits can be attributed to an increase in general well-being. Music has other effects which have not yet been understood. According to Professor Robertson, a scientist and musician, some effects of music are mysterious and are, therefore, being investigated further. It has been suggested that the sounds and rhythms of music help stimulate the brain and send electrical messages to the muscles. 5. Science, however, demands facts and hard evidence. Many in the medical profession have not yet recognized the healing benefits of music, since reports have been based mainly on various stories of evidence. These new studies could provide proof to doctors that music is a suitable treatment for many conditions. One day doctors may even “prescribe“(开处方)music, but that could be a long time in the future.

A Doctor in the House Brushing your teeth twice a day should keep the dentist away. But if a group of scientific researchers have their wish, it will make the rest of your body healthy too.【B1】______It is one of many gadgets(小装置)proposed by engineers and doctors at the Center for Future Health in New York-others include a pair of glasses that help to jog your memory, and a home camera designed to check for cancer. The devices seem fanciful, but the basic principles are simple. The gadgets should make it easy for people to detect illness long before it strikes and so seek treatment far earlier than normal.【B2】______In the long run, the technology may even prevent illness by encouraging us to lead healthier lives. Intelligent bandages(绷带)are a good example. Powerful sensors within the bandage could quickly identify tiny amounts of bacteria in a wound and determine which antibiotics(抗生素)would work best.【B3】______ Socks are long overdue for a makeover. In the future they will be able to automatically detect the amount of pressure in your foot and alert you when an ulcer(溃疡)is coming up. All the projects should have far-reaching implications, but the biggest single development is a melanoma(黑瘤)monitor designed to give early warnings of cancer.【B4】______If a problem is found, the system would advise you to get a check-up at your doctor’s surgery. If all this sounds troublesome, then help is at hand.【B5】______A standard computer would be able to understand your voice and answer questions about your symptoms in plain English and in a way which would calm your nerves. A. The device could be used to take a picture of your body each week, then compare it with previous images. B. That is going to be the difficult part. C. The cut could then be treated instantly, so avoiding possible complications. D. Instead of relying on hi-tech hospitals, the emphasis is shifted to the home and easy-to-use gadgets. E. Experts are also working on a “digital doctor“, complete with a comforting bedside manner. F. A toothbrush that checks blood sugar and bacteria while your brush is currently in development in USA.

The Development of Ballet Ballet is a dance form that has a long history. The fact that it survives to this day shows that it has adjusted as times have changed. Ballet began in the royal courts during the Renaissance. At that time it became common for kings and queens, as well as other nobility(贵族), to participate in pageants that included music, poetry, and dance. As these entertainments moved from the Italian courts to the French ones, court ladies began participating in them. Though their long dresses prevented much movement, they were able to perform elaborate(复杂的)walking patterns. It was not until the 1600s that women dancers shortened their skirts, changed to flat shoes, and began doing some of the leaps and turns performed by men. It was also in the 1600s that professional ballet began. King Louis XIV of France, himself a devoted dancer, founded the Royal Academy of Dance. The five basic feet positions from which all ballet steps begin were finalized. In the late 1700s another important change occurred. Ballet began to tell a story on its own. It was no longer simply dance to be performed between acts of plays. Elaborate wigs(假发)and costumes were eliminated. By the early 1800s dancers learned to rise on their toes to make it appear that they were floating. Classical ballet as we know it today was influenced primarily by Russian dancing. The Russians remained interested in ballet when it declined in other European countries in the mid-1800s. One of the most influential figures of the early 20th century was Sergei Diaghilev. His dance company, the Ballets Russes, brought a new energy and excitement to ballet. One of his chief assistants, George Balanchine, went on to found the New York City Ballet in 1948 and to influence new generations of dancers.

Late-night Drinking Coffee lovers, be careful. Having a quick “pick-me-up“ cup of coffee late in the day will interrupt your sleep. As well as being a stimulant(兴奋剂), caffeine interrupts the flow of melatonin(褪黑激素), the brain hormone that sends people into a sleep. Melatonin levels normally start to rise about two hours before bedtime. Levels then peak between 2 am and 4 am, before falling again. “It’s the neurohormone(神经激素)that controls our sleep and tells our body when to sleep and when to wake, “says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the body’s levels of this sleep hormone. Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six volunteers slept less well after a cup of caffeinated coffee than after drinking the same amount of decaf(脱咖啡因咖啡). On average, subjects slept 336 minutes per night after drinking caffeinated coffee, compared with 415 minutes after decaf. They also took half an hour to drop off, twice as long as usual. In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine(尿)sample. Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those in decaf drinkers. In a paper accepted for publication in Sleep Medicine, the researchers suggest that caffeine blocks production of the enzyme(酶)that drives melatonin production. Because it can take many hours to eliminate caffeine from the body. Ohayon recommends that coffee lovers switch to decaf after lunch.
