The richest man in the world can now also claim a degree from the college he dropped out of three decades ago. Microsoft Chairman Bill Gates delivered the commencement address at Harvard University on Thursday, and was awarded the L. L. D. honorary doctorate . "Our speaker is known as the most influential entrepreneur of the personal computer revolution. He was named as one of the 100 most influential people in the world in 2004, 2005, 2006 and again in 2007, " said Harvard's president, Derek Bok. Then Bok spoke more directly to Gates: "Just think what you could have achieved if you had stayed another two years." Gates told the students, many of whom will soon be launching into full-time careers, that work isn't the only thing of importance. "Judge yourself not on the professional accomplishments but on how well you have addressed the world's inequities, how you have treated people who have nothing to do with you," he said. In recent months, Gates has been giving a larger part of his time and energy to the Bill & Melinda Gates Foundation, which focuses on issues including global health and education. In 2008, he plans to make the foundation his chief responsibility. But for the most part, the Microsoft co-founder stuck to the serious message about trying to make the world a better place. He urged the graduates not to get discouraged about seemingly intractable challenges of poverty and poor health. As many as 30,000 people were expected to attend the outdoor commencement ceremony. Gates wasn't the only high-profile speaker on the prefix = st1 /Cambridgecampus this week. On Wednesday, former President Bill Clinton delivered Harvard's Class Day speech. Gates and Clinton have collaborated on great efforts to fight the AIDS epidemic in developing countries. Recent past Harvard commencement speakers have included journalist Jim Lehrer in 2006, actor and writer John Lithgow in 2005 and United Nations Secretary General Kofi Annan in 2004. On this special day, Bill Gates has done all the following EXCEPT that _ . A) he claimed a degree B) he used much of his time and energy to his Foundation C) he gave a speech.

Q: Over the years, Americans have become used to salt. Most people have no idea how much salt they consume --on average, about 9 to 12 gram per person per day, according to the American Heart Association. That's twice the amount recommended by the government. A new study last week showed eating even a little less salt could greatly help the heart. The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes , four percent fewer deaths and eleven percent fewer new cases of heart disease. Researchers also found that the benefits would be greatest for African Americans and women. As a group, African Americans tend to have higher blood pressure than the general population, and "many studies suggest that they may be more sensitive to salt," says Dr. Kirsten Bibbins-Domingo, an epidemiologist at the University of California, San Francisco. Her analysis found that a reduction of 3 gram of salt per day would reduce heart attacks 8% on average; among African Americans, that rate would drop 10%. A similar result was found in women, whose stroke risk dropped 8% with a 3-g reduction in salt intake; in men, the risk fell 5%. They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt. However, other scientists say such a campaign is an experiment with the health of millions of people. Michael Alderman, a high blood pressure expert and professor at Albert Einstein College of Medicine in New York, says that eating less salt results in lower blood pressure. But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes. "Salt has other biological effects. Calling for reductions in the national diet could have good effects, as well as harmful results. There is not enough evidence either way." The passage is written mainly to _ . A) comment B) persuade C) introduce D) scold

Narayana Hrudayalaya, a complex of health centers based in southern India, offers low-cost, high-quality specialty care in a largely poor country of 1.2 billion people. By thinking differently about everything from the unusually high number of patients it treats to the millions for whom it provides insurance, the hospital group is able to continually reduce costs. Narayana Hrudayalaya's operations include the world's largest and most productive cardiac hospital, where the average open-heart surgery runs less than $2,000, a third or less what it costs elsewhere in India. Narayana Hrudayalaya's origins date back to 2001, when it built its massive cardiac center on the outskirts of Bangalore. But it has expanded since then into what founder Dr. Devi Shetty calls a "health city," a series of centers specializing in eye, trauma, and cancer care. Narayana Hrudayalaya now manages or owns hospitals in 14 other Indian cities. Expanding access is paired with a ongoing focus on efficiency. Typically, says Shetty, private hospitals in India focus on patients who can easily afford treatment. "We did it the other way around," he says. "This hospital is for poor people, but we also treat some rich people. We don't look at people who are sgabbily dressed and have trouble paying as outsiders. " Narayana Hrudayalaya's flagship hospital has 3,000 beds and negotiates for better prices and buys directly from manufacturers, cutting out distributors. In addition to cost-cutting, Narayana Hrudayalaya finds creative ways to make the economics work. The company started a micro-insurance program backed by the government that enables 3 million farmers to have coverage for as little as 22 cents a month in premiums . Patients who pay discounted rates are in effect compensated by those who pay full price Doing something--doing more, actually--is the point. By 2017, Shetty, 58, plans to expand from 5,000 beds throughout India to 30,000. Before becoming one of India's best-known health-care entrepreneurs, Shetty was its best-known heart... Narayana Hrudayalayastarted a micro-insurance to _ . A) cut down on the cost of the treatment B) get the support of the government C) make the company run smoothly D) attract more people to its hospital
