2、ading Comprehensio(总题数：1，分数：71.00)Cholesterol and Heart Disease Do you know your cholesterol level? Many people dont. A high level of cholesterol in the blood is an important risk factor for heart disease. Some people say that the danger of heart disease is exaggerated. However, heart disease is a m

3、ain cause of death in developed countries. Every year more than one million Americans have heart attacks, and half of them die. People With heart disease suffer chest pains that make simple activities, such as walking, shaving, or taking a shower, difficult. Research has proven that cholesterol leve

4、ls are Connected with heart disease. One project in Massachusetts has studied the same group of men and women since 1948. The researchers have found that the people who have high levels of cholesterol have more heart attacks. A natural substance in the blood, cholesterol comes from the liver. The am

5、ount of cholesterol is affected by diet and by physical qualities we inherit from our parents. One kind of cholesterol sticks fat to the walls of arteries, making them smaller and finally blocking them. It produces a condition called “hardening of the arteries,“ which causes heart attacks. With tiny

6、 cameras, doctors can see blood circulating through the heart valves. Angiograms (血管造影照片) are x-rays of the heart arteries. They show fat deposits and blockages caused by high cholesterol. Heart disease begins in children as young as 3 years old. It occurs earlier in boys than in girls. Nearly half

7、of teenagers have some fat deposits on their artery walls. Heart disease develops faster if we have high cholesterol levels and also smoke. What is a safe level of cholesterol? Adults have a high risk of heart attack if their cholesterol level is above 240 milligrams per deciliter (1/10 公升) of blood

8、. Below 200 is better. In the Massachusetts study, no one with a cholesterol level below 150 has ever had a heart attack. However, about half of American adults have cholesterol levels above 200. To lower our cholesterol level, we must change our eating habits. Anything that comes from an animal is

9、high in fat and high in cholesterol. The American Heart Association National Cholesterol Education Program says that fat should be no more than 30 percent of our diet. Blood cholesterol levels start to fall after 2 to 3 weeks of following a low-cholesterol, low-fat diet. Dietary changes alone can re

10、sult in a 10 percent reduction of the average persons cholesterol level. Aerobic exercise helps, too. Artery blockage can be reduced by as much as 40 percent through changes in diet and amount of exercise. We must educate everyone, including children in elementary schools. We must teach them respons

11、ibility for their health through classes in nutrition and aerobic exercise. For example, the smart snack is fruit. Children must be served fruit in the school cafeteria, along with low-fat meals. Schools must send recipes home with the children. Parents must include children in planning and preparin

12、g meals and shopping for food. Adults, including persons over the age of sixty five, can lower their cholesterol by 30 or 40 percent. It is never too late to change. One man began his health program when he was seventy- three. By the time he was seventy-seven, he had lowered his arterial blockage fr

13、om 50 percent to 13 percent and his cholesterol from 320 to 145 without drugs. He went on a vegetarian diet with only 10 percent fat, plus programs to reduce stress and get more exercise. A low-cholesterol diet that cuts out most animal products and high-fat vegetables may be unfamiliar to people. T

14、he Heart Association says to use no added fat of any kind. Dont fry food in oil. Cook it in water, vinegar, or vegetable water. Learn about grains and vegetables. Avoid egg yolks (the yellow part of the egg). Eat potatoes, beans, low fat vegetables, and fruit. People often complain about low-fat die

15、ts before they have had time to get used to them. Food can taste good without cream, butter, and salt. You can use olive oil, mustard, fresh herbs, or yogurt instead. A new diet can cause general anxiety, when people feel worried and nervous about what is going to happen. They must learn to deal wit

16、h the changes in their lives. Sometimes major changes in diet or lifestyle are easier than minor ones because the results are bigger and faster. Fast results encourage us. How can you control the amount of fat in your diet if you eat in restaurants? Restaurants must provide healthy meals that are lo

17、w in fat, salt, and cholesterol. A diet is a personal thing. Restaurant owners should not make customers feel embarrassed because they want to follow a diet that is good for them. Restaurant owners must learn to give equal service to customers on a healthy diet. Some restaurants have items on the me

18、nu marked with a heart to show that they are low in fat, cholesterol, salt, or sugar. A few restaurants serve only these recipes. Heart disease causes one out of every four deaths in East Harlem in New York City. The East Harlem Healthy Heart Program is an educational program. It has 2 goals: to get

19、 people to change their diets and to find volunteers to help run educational activities. One way it educates is by street shows. Actors wear costumes and carry big pieces of plastic fat. They entertain so people will listen. Groups of children perform songs and dances that educate people about heart

20、 disease and diet. Volunteers lead walking and exercise groups to show people how to begin exercising. Volunteers also stand in supermarkets to suggest healthy food choices to shoppers. The volunteers have shoppers taste two kinds of milk to see which tastes better. Most people are surprised that th

21、e low-fat milk tastes better than the whole milk. Shoppers are encouraged to buy low-fat milk instead of whole milk. Education costs money, but it also brings results. In 1983, only 35 percent of the American public knew their cholesterol levels. By 1990, 65 percent of the people had had theirs chec

22、ked. People feel better if they lower their cholesterol through diet. Healthy people are more confident. They are more attractive to themselves, as well as to others. Their friends stare at them because they look so healthy. We can prevent heart disease by living a healthful lifestyle and eating the

23、 right kind of diet.

42、 developed is unknown. They probably came about just to give children something to do. In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly determined, boys pattern their play after the activities of thei

43、r fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world. What is remarkable about the history of toys is not so much how they changed over the centuries but how much the

44、y have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the world and their persistence to the present that is amazing. In Egypt, the Americas, China, Japan and among

45、the Arctic (北极的) peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles. Because toys can be generally regarded as

46、a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the oxcart to the automobile is a direct line of ascent (进步). The progress from a rattle (拔浪鼓) used by a baby in 3000 BC to one used by an infant today, ho

47、wever, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials. （分数：177.50）(1).The reason why the toys most boys play with are different from those that girls play with is that _.（分数：35.50）A.their soc

48、ial roles are rigidly determinedB.most boys would like to follow their fathers professionsC.boys like to play with their fathers while girls with their mothersD.they like challenging activities(2).One aspect of “the universality of toys“ lies in the fact that _.（分数：35.50）A.technological advances have greatly improved the durability of toysB.the improvement of craftsmanship in making toys depends on the efforts of universitiesC.the exploration of the universe has led to the creation of new kinds of toysD.the basic characteristics of
