Each of us can live strong，healthy，energetic lives for a long time to come．The key？Actually，there are many of them．

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(自由基) 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? Discover something more meaningful to devote yourself to and do it wholeheartedly．

Wikipedia is an online encyclopedia（百科全书）．This name is a combination of“wiki" and “encyclopedia"． Wiki is the Hawaiian word for quick． Wiki websites are designed to enable users to make addition or edit any page Of the site．

Wikipedia has been accused of exhibiting systemic prejudice and mistakes．Critics argue that Wikipedia's open nature and a lack of proper sources for much of the information makes it unreliable,

Mention Wikipedia within the walls of academy and you'll find no shortage of opinions．That-s no surprise．Can an online encyclopedia that is edited by anyone be trusted as a credible information source? Should students be encouraged to use this tool? And is it even possible to discourage its users?

To find out, we performed a simple experiment．We selected 100 terms from the U．S．history textbooks, We chose a mix of items that students might be asked to research for a test or paper and we entered each item into Google to find out which websites the search engine suggests as the most useful links． The results are shocking． Google listed Wikipedia as the number one： 87 times out of 100．

Several conclusions can be drawn from this finding． First, people searching for information about these historical terms are finding the entries from Wikipedia helpful．Second, 6'banning" the use of Wikipedia appears hopelessly simple-minded．Jimmy Wales, one of Wikipedia's founders, told the New York Times, "They might as well suggest not listening to rock & roll either"．

To our untrained eyes, the information from Wikipedia appeared just as reliable．The reason why the content is mostly reliable is probably that these terms are rather mainstream．The high-school level content is less likely to be wrong than the subjects studied in graduate schools． So when primary and secondary students are researching history, Wikipedia is still a proper place to start．

1.Which of the following can best describe Wikipedia?

A．Wikipedia is from the Hawaiian language with the meaning of prejudice and mistakes．

B．Wikipedia is an online encyclopedia edited freely．

C．Wikipedia is an encyclopedia under public attack．

D．Wikipedia is a tool for enjoying rock & roll．

2.What does "it" in the second paragraph refer to?

In the quest for better health, many people turn to doctors, self help books or herbal supplements. But they overlook a powerful weapon that could help them fight illness and depression, speed recovery, slow aging and prolong life: their friends.

Researchers are only now starting to pay attention to the importance of friendship and social networks in overall health. A 10-year Australian study found that older people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the risk for obesity among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could promote brain health as we age.

“In general, the role of friendship in our lives isn’ t well appreciated,” said Rebecca G. Adams, a professor of sociology at the University of North Carolina, Greensboro. “There are a lot of things on families and marriage, but very little on friendship. It baffles me. Friendship has a bigger impact on our psychological well being than family relationships.”

Bella DePaulo, a visiting psychology professor at the University of California, Santa Barbara, whose work focuses on single people and friendships, notes that in many studies, friendship has an even greater effect on health than a spouse or a family member.

It isn’ t entirely clear why friendship has such a big effect. It may be because people with strong social ties also have better access to health services and care. Beyond that, however, friendship clearly has a profound psychological effect. People with strong friendships are less likely than others to get colds, perhaps because they have lower stress levels.

Last year, researchers studied 34 students at the University of Virginia, taking them to the base of a steep hill and fitting them with a weighted backpack. They were then asked to estimate the steepness of the hill. Some participants stood next to friends during the exercise, while others were alone.

The students who stood with friends gave lower estimates of the steepness of the hill. And the longer the friends had known each other, the less steep the hill appeared.

“People with stronger friendship networks feel like there is someone they can turn to，” said Karen A．Roberto, director of the center for gerontology (老年医学) at Virginia Tech.“ Friendship is an undervalued resource. The consistent message of these studies is that friends make your life better.”
