Eat fewer calories,but more food Slimming down can help prevent disease,and cutting way back on the amount you eat may even slow the aging process.When nutrition researchers invited themselves over for dinner in kitchens across the globe-from Greece to Japan to the state of Pennsylvania--they discovered a stomach-satisfying secret to good health:Pile your plate high with vegetables and fruits,add respectable parts of beans and whole grains,and ignore high-calorie food like cheeseburgers,cream sauces,and fatty meats. Use exercise as an anti-aging vaccine Exercise can help you gain a better quality of life as you age.It's no secret that physical activity strengthens muscles,burn calories,and puts a happy bounce in your step.But recently,researchers discovered a new,extra benefit:Exercise acts as a powerful way against the aging process itself. When exercise physiologists put healthy people aged 60 to 85 on Weight-training programs for six months then tested them for signs of free-radical damage,they were surprised by the results.By the end of the study,low-intensity exercisers had a drop in free-radical damage,while high-intensity exercisers had a slight increase. Find something interesting to do Life is always busy no matter what your age.But the truth is,when people are retired,time usually does become more available for adults after 60.With this time come choices.The easy one is merely to relax:watch more TV,eat out more often,talk on the phone as much as you want.The better choice?

Ques: Jack Andraka from Maryland won the grand prize at the 2012 Intel International Science and Engineering Fair. It is the largest high school science competition in the world. The Maryland teenager is the youngest winner of the $75,000 prize. He was chosen from among 1,500 students in 70 countries. Jack Andraka invented a test for pancreatic cancer . He started to learn it after losing a close family friend to the disease. "I went on the Internet and I found that 85%of all pancreatic cancers are found late, when someone has less than 2% chance of survival , " he says, "and I was thinking,' That's not right. We should be able to do something.'" He found that early discovery is important to increasing the chances of surviving the disease. The Maryland teenager asked to work in a laboratory at Johns Hopkins University in Baltimore and was allowed. There he developed a simple paper test, which can recognize the disease in a single drop of blood. His test has proved correct 90% of the time. It also is 100 times more sensitive than other tests. "It costs 3 cents per test, and then it takes only 5 minutes to run," he said. Jack's success wouldn't have been possible without Anirban Maitra, a professor at Johns Hopkins. He was the only person among the 200 researchers Jack wrote to who showed interest in his project. "I was very surprised that this was a 15-year-old who was writing this. I wanted to meet this clever young man and see what he wanted to talk about and so I called him over for an interview . " Jack worked in Professor Maitra's laboratory, completing his project in 7 months. The government has given the Maryland teenager patent rights to the pancreatic cancer test. He is now talking with companies about developing the test into a simple product. Whatever happens, the professor believes Jack Andraka's name is one we will be hearing again over the next 10 to 20 years. We can infer from the text that Jack Andraka _ . A) left a deep impression on Professor Maitra B) was thought highly of by companies C) got support from others easily D) wasn't afraid of failure

Question: What is great art? On the one hand, we can all see that great art is old art which is called great. But how do we know which art of our own times is great, and which will be forgotten? And who decides? These are important questions, for the great art of the past often was not considered great during its own time. When Shakespeare and Charles Dickens were writing, for example, most critics considered them as hack writers with little or no literary ability. Similarly, Van Gogh and many of the other Impressionist painters of the late nineteenth century were not allowed to participate in events involving what were thought to be the "real" painters of the time, and often they were very poor. Yet today their paintings often sell for millions of dollars, while those so-called "real" painters are now barely remembered. So what makes great art? Can, for example, rock music be great art? Music videos? Cartoons and comics? Those who call themselves critics of the fine arts often have been the last to recognize great art in the past, and we can probably expect this to be the situation today. Critics often don't recognize great art because they tend to be prejudiced against what is popular. Popular works, whether they are novels, movies, or comics, are usually considered to be produced for the sake of money only, and not for the sake of art. But popularity, it seems to me, is one of the three signs that a present-day work of art may come to be thought of as great. The other two are that it is groundbreaking, and that it is inherently beautiful. Many works have one or even two of these qualities of being popular, unusual, and beautiful. But having all the three often will mean that a work of art will someday be seen to be great, though it may take a good spoonful of time, such as a century or two, to know for sure. What can be inferred from the passage? A) Critics have changed their attitudes to great works. B) Most of the opinions of critics are valueless. C) The work of art itself, not the critics, determines its greatness. D) Works of Impressionist painters will be great one day.
