2020年安徽农商行考试英语知识练习题（9）

　　The American Heart Association and other groups have said for many years that people could reduce the chance of suffering a heart attack by eating less of the foods rich in cholesterol （胆固醇）. These include such foods as meats, milk products and eggs. The Heart Association noted a number of studies which show that nations where people eat a lot of high cholesterol foods have a higher number of deaths from heart disease.

　　However, the new report disagrees. It was made by the Food and Nutrition Board of the United States National Academy of Sciences. The new report by a team of 15 scientists said there is no evidence to link cholesterol in food directly to heart disease. It noted seven major studies involving people whose diet was changed to include only foods low in cholesterol. The studies found only a very small reduction in the number of heart attacks and there was no reduction in the number of heart attack deaths.

　　Other studies have shown similar results. They found that a change to low cholesterol foods will have only a minor effect on the amount of cholesterol in a person's blood and only a minor effect on the number of deaths.

　　Medical scientists hope that two huge new studies may settle the cholesterol dispute. The tests are designed to learn if low cholesterol foods or anti-cholesterol drugs, or both, can reduce the amount of the substance in the blood and reduce the chance of a heart attack. The two new studies will be finished in the next year or two.

　　The new Academy of Sciences report also discussed other possible links between food and disease. The scientists, in general, they are deeply concerned about some of the recent advice given about food. They noted that a number of private groups, government agencies and several popular books have advised that people can prevent heart disease, cancer and other sicknesses by changing the kinds of foods they eat. The new report said there is often no good scientific evidence to support such advice. In fact, the scientists said such ideas often produce only false hopes or unnecessary fears.

　　High cholesterol foods include ____?

　　A. eggs, meats and milk products

　　B. potatoes, green vegetables and tomatoes

　　C. corn, wheat and beef

　　D. sugar, rice and butter






 

　　【答案】A。高胆固醇的食品包括鸡蛋、肉类和牛奶制品。这是一般常识，而且在短文中有明确表达：These include such foods as meats, milk products and eggs. A项选择正好符合题意，故为正确答案。B项蕃薯、青菜和西红柿。薯类和蔬菜不含脂肪，不含胆固醇。C项玉米、小麦和牛肉。玉米、小麦含有淀粉，自然没有胆固醇，牛肉虽然含有少量的胆固醇，但在C项选择里占有三分之一的份额，故不能归到胆固醇食品的行列。D项糖、大米和奶油，和C项选择一样，也不能归为含胆固醇食品一类。故本题应选A。
