Food and Cancer

Medical experts have suspected for many years that there is a strong link between what a person eats and
cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of
developing cancer. A team of Chinese and American scientists did the study.They are from American
National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical Sciences in Beijing.
The Journal of the National Cancer Institute published the results of the study. About thirty thousand people
between the ages of 40 to 69 took part in the study.They were from the northern central Chinese area of
Linxian.Most of them took vitamins and minerals everyday for five years.
Linxian was chosen because the people there have an extremely high rate of cancer of stomach and
esophagus.Researchers believe that fungus and molds in local foods may be partly responsible for the high
cancer rate.Researchers divided those people into eight groups.Seven of the groups received different
mixtures of vitamins and minerals daily.The amounts of the vitamins and minerals were 1 to 2 times greater
than what American health officials say is needed.The eighth group received sugar pills that had no effect.
Those who seemed to gain the most received a mixture of a form of vitamin A called β-carotene,vitamin E
and the mineral selenium（硒）.The vitamin and mineral are believed to prevent damage to cells caused by
cancer-causing substances.Researchers reported a 1 3 percent drop in cancer rates in those who took
β-carotene,vitamin E and selenium.They also found a 10 percent drop in the number of deaths caused by
strokes from bursting blood vessels.
Scientists warn that it is too soon to know if the effect would be the same among people in other
countries.They note that the people in Linxian eat foods that lack necessary vitamins and minerals.Chinese
officials will continue to record the health records of the people in Linxian for many years.For now officials
reportedly are considering using the results of the study.They want to find a way to improve the health of
people in Linxian and other small towns in China.

All those people who took part in the study received vitamins and minerals.
A:Right
B:Wrong
C:Not mentioned

参考答案

参考解析
解析：文章第一段第一句“Medical Experts have suspected for many years that there is a strong link between what a person eats and cancer.They say a new study provides the first evidence that vi- tamins could reduce a person ' s chance of developing cancer.”意思是“医学专家很多年来一直怀 疑人们的饮食和癌症之间有直接的联系，他们（医学专家）一项新的研究提供了第一个证 据······”，因此可见新的研究结果不是意料之外，而是意料之中的。
文中说来自中美两家研究所的科学家们共同进行了此项研究，并没有提及具体人数。 故C为正确答案。
由文章第一段最后一句“Most of them took vitamins and minerals everyday for five years." 可知，大多数实验对象连续5年每天服用各种维生素及矿物质，因此可推知，实验大约持续了5 年。故A为正确答案。
文章第二段的开头说林县人胃癌及食道癌发病率极高，但并没有说在国内是最高的。 故C为正确答案。
文章第二段中提到，研究者认为，此地食物中的真菌和霉菌是癌症发病率高的一个原 因。故A为正确答案。
文章第二段中提到，研究者把实验对象分成8组，其中的7组每天服用不同的维生素和 矿物质混合物，第8组服用毫无作用的糖丸。故B为正确答案。
文章最后一段第一句“Scientists warn that it is too soon to know if the effect would be the same among people in other countries."，意思说“目前太早了还不能知道是否这个影响对其他 国家的人们是一样”；最后一句“They want to find a way to improved the health of people in Linx- ian and other small towns in China."，在最后一句中提到仍然是宁夏和中国的其他小城市的问 题。因此判断问题干句的说法不正确。第3部分：概括大意与完成句子

考题 共用题干 Napping to a Healthier Heart?1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heartdisease patient should affect that person’s treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in theJournal of the American Medical Association.5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelatedstudy earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children. But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in theUnited States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not takenaps.6 The researchers say napping may improve heart health by reducing stress.They say the researchsuggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.If a person has a high level of NT-proBNP_________.A: where fewer pepole die from heart problemB:whether they have the risk of heart attack,heart failure or stroke C:would probably have lower rates of heart diseaseD:how to test a person's NT-proBNP level in the blood by himselfE:his heart muscle would be under pressure in some wayF:that napping is of great benefit to women too

The first appearance usually is between the ages of 18 and 25.In some cases it develop3 after a tragedy,like the death of a loved one,or some other difficult situation.In the United States,the National Institute of Mental Health says more than two million people are af- fected in any one-year period.The American Psychological Association says panic disorder is twice more like- ly in women than men.And it can last anywhere from a few months to a lifetime.Panic attacks can be dangerous一for example,if a person is driving at the time.The Chesapeake Bay Bridge in the state of Maryland is so long and so high over the water,and it is famous for scaring motorists. There is even a driver assistance program to help people get across.Some people who suffer a panic attack develop a phobia,a deep fear of ever repeating the activity that brought on the attack.But experts say panic disorder can be treated.

考题 共用题干 Food and CancerMedical experts have suspected for many years that there is a strong link between what a person eats and cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of developing cancer. A team of Chinese and American scientists did the study.They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical Sciences in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study.They were from the northern central Chinese area of Linxian.Most of them took vitamins and minerals everyday for five years.Linxian was chosen because the people there have an extremely high rate of cancer of stomach and esophagus.Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate.Researchers divided those people into eight groups.Seven of the groups received different mixtures of vitamins and minerals daily.The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed.The eighth group received sugar pills that had no effect.Those who seemed to gain the most received a mixture of a form of vitamin A called β-carotene,vitamin E and the mineral selenium（硒）.The vitamin and mineral are believed to prevent damage to cells caused by cancer-causing substances.Researchers reported a 1 3 percent drop in cancer rates in those who took β-carotene,vitamin E and selenium.They also found a 10 percent drop in the number of deaths caused by strokes from bursting blood vessels.Scientists warn that it is too soon to know if the effect would be the same among people in other countries.They note that the people in Linxian eat foods that lack necessary vitamins and minerals.Chinese officials will continue to record the health records of the people in Linxian for many years.For now officials reportedly are considering using the results of the study.They want to find a way to improve the health of people in Linxian and other small towns in China. The rate of cancer of stomach and esophagus in Linxian is the highest in China.A:RightB:WrongC:Not mentioned
