Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Millions of U.S. college students will have to shoulder more of the cost of their education under federal rules imposed late last month through a bureaucratic(官僚政治的) adjustment requiring neither Congressional approval nor public comment of any kind. The changes, only a slight alteration in the formula governing financial aid, are expected to diminish the government's contribution to higher education by hundreds of millions of dollars, starting in the autumn of 2004. But they will also have a ripple effect across almost every level of financial aid, shrinking the pool of students who qualify for federal awards, tightening access to billions of dollars in state and institutional grants, and heightening the reliance on loans to pay for college.
How much more money this may require of students and their parents will vary widely, changing with each family's set of circumstances. Some families may be expected to pay an extra $100 or less each year, while others may owe well over $1,000 more. While many college administrators characterized the change as a backdoor way to cut education spending, without public discussion, the Department of Education said it was simply executing its responsibilities under federal law.
Whether furnished by colleges, states or the federal government, the vast majority of the nation's $90 billion in financial aid is dictated by a single, intricate equation known as the federal need analysis. Its purpose is to make out how much of a family's income is truly discretionary(自由支配的), and therefore fair game for covering college expenses. Much like the federal income tax, the formula allows families to deduct some of what they pay in state and local taxes. But, this year, the department significantly reduced that amount, in some cases cutting it in half. On paper, at least, that leaves families with more money left over to pay for college, even though state and local taxes have gone up over the last year, not down.
In the 2004—2005 academic year, when the changes first take effect, parents who earn $50,000 a year may be expected to contribute $700 or so beyond what they are already paying, according to an independent analysis conducted by a consulting firm that helps universities set enrollment and aid. Those earning about $25,000 may owe only an extra $165 or less, while families earning $80,000 could be expected to pay an additional $1,100 or more.
The expression "ripple effect"(Para. 1) most probably means" __________ ".
A．A hard working ambitious young man.B．A young man good at managing his time.C．A colle

Cholesterol and Heart Disease
Do you know your cholesterol level？ Many people don't. 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 main 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 levels 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 amount of cholesterol is affected by diet and by physical qualities we inherit from our parents. One kind of cholesterol sticks fat to the wails of arteries, making them smaller and finally blocking them. It produces a condition called "hardening Of the arteries," which causes heart attacks. With tiny 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 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. 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 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 result in a 10 percent reduction of the average person's 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 responsibility 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 preparing 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 from 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. The Heart Association says to use no added fat of any kind. Don't 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 d
