In the past, it was often considered
28、 a death sentence. But many patients now live longer【C1 】_of improvements in discovery and treatment. Researchers say death【C2】_in the United States from all cancers combined have fallen for thirty years. Survival rates have increased for most of the top fifteen cancers in both men and women, and fo
29、r cancers in【C3】_. The National Cancer Institute and the Centers for Disease Control and Prevention studied the number of cancer survivors. A cancer survivor is defined【C4】_anyone who has been found to have cancer. This would include current patients. The study covered the period from 1971 to 2001.
30、The researchers found there are three【 C5】_as many cancer survivors today as there were thirty years ago. In 1971, the United States had about three million cancer survivors. Today there are about ten million. The study also found that 64% of adults with cancer can expect to still be【C6】_in five yea
31、rs. Thirty years ago, the five-year survival rate was 50%. The government wants to【C7】_the five-year survival rate to 70% by 2010. The risk of cancer increases with age. The report says the majority of survivors are 65 years and older. But it says medical improvements have also helped children with
32、cancer live【C8】_longer. Researchers say 80% of children with cancer will survive at least five years after the discovery. About 75% will survive at【C9】_ten years. In the 1970s, the five-year survival rate for children was about 50%. In the 1960s, most children did not survive cancer. Researchers say

After the shock they may remain unconscious, becom
36、e semiconscious or be conscious but confused and dazed, at least for a time. Flashes of light may continue passing before their eyes, and blindness and deafness may follow. The nervous system may be badly affected, causing paralysis, pain in the limbs and even hemorrhage. There will be burns where t
37、he lightening passed through the body, and like all electrical bunts, they are often deep and sever. All persons, especially campers and hunters, should know how to give first aid to someone who has been struck by lightening. Do not be afraid to touch the victim. You wont get a shock. The lightening
38、 has already been grounded. Remember that speed is of the greatest importance in severe cases. The first thing to do is to loosen tight clothing about the throat and waist. Then clear the air passages of mucus (黏液) if present, and apply artificial respiration if necessary. Give mouth-mouth resuscita
39、tion if needed, or give oxygen if available. Many victims thought to be dead have been revived after treatment. Send someone for a doctor as soon as possible, but dont leave the victim alone. If a doctor is not available, take the person to a hospital as soon as the person can be safely moved. Signs
40、 of shock are: pale, cold, sticky skin; weak, rapid pulse; shallow, irregular breathing or, in extreme cases, no breathing at all. To treat shock, you must keep the patient lying down with the head lower than the feet and cover him or her with a blanket but watch out for overheating. Giving a stimul
41、ating hot tea or coffee will help, but only if the patient is thoroughly conscious. After breathing has been restored and shock is treated, treat the burns. Apply some salve and cover them with a clean cloth or a sterile dressing. If conscious, the patient will be badly frightened, so do all you can
42、 to reassure. A little knowledge and a helping hand may save someones life.61 The passage mainly talks about_.（A）which metals conduct electricity best（B） where to go in a thunderstorm（C） how to treat someone struck by lightening（D）how to make mouth-to-mouth resuscitation62 According to the passage,

And indeed, cu
46、tting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrateswhich break down into amino acids and sim
47、ple sugars, respectively, and can be used to strengthen and energize the body dietary fat is more easily converted to body fat. Therefore, its more likely to stay on buttocks, thighs and bellies. But cutting fat from your diet doesnt necessarily mean your body wont store fat. For example, between no
48、nfat and regular cookies, theres trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight
49、 gain. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasnt losing weight. Then he showed his food diary to his coach and revealed hed been eating half a pound of jelly beans a day. “They dont have any fat, “ he explains. But they had enough sugar to keep him from shedding an ounce. Nonfat foods become add-
