To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．

After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't．

“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”

Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．

Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．

“We can't say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what's theoretically（理论上地）possible．”

“Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”

Which of the following DOESN'T belong to the four healthy habits?

A．Eat five servings of fruits and vegetables a day．

B．Do proper exercise in the morning every day．

C．Drinking alcohol in the proper amount every day．

D．Having a cigarette before going to bed every day．

We can learn from the passage that ．

A．Susan Jebb did not take part in the study．

B．the study observed people as well as tested specific changes．

C．there's no need for people under 45 to adopt these good habits．

D．only those from first class can benefit from these healthy behaviors．

What can be inferred from the passage?

A．All the people are well aware of the harm of their bad habits．

B．People aged 45 to 70 have bad habits in the United Kingdom．

C．Governments should take measures to help people change their bad habits．

A healthy dose of sunshine may be the secret to staying young, British scientists have disclosed.
Vitamin D is produced naturally by the skin in response to sunlight and may help to slow the ageing process and protect against heart disease, according to the study.
Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres - a biological marker of ageing found in DNA．As people get older, their telomeres get shorter and they are easy to have illnesses.
But the study found women with high levels of vitamin D had comparatively longer telomeres - a sign of being biologically younger and healthier.
The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.
Lead researcher Dr Brent Richards said: "These results are exciting because they prove for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D．
"This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer."
He said further studies are required to confirm the findings.
Professor Tim Spector, head of KCL's twin research unit, and a co-author of the report, added: "Although it might sound absurd(荒谬的), it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process."
Vitamin D made by the action of sunlight on the skin accounts for 90 per cent of the body's supply, but lower levels can also be obtained through food such as fish, eggs and breakfast cereals.
Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.

Recreational tree climbing is taking root in the ecotourism industry, and it's sending guys like Tim Kovar to far off reaches of the globe. Kovar, a tree-climbing instructor, recently returned to the U.S. from Brazil, where he spent time developing a tree-climbing operation thanks to the "slow travel" movement.

Slow travel, is like the slow food movement, the practice of giving fast food in favor of homegrown cooking—the kind that takes hours to prepare and enjoy. Likewise, slow travel urges visitors to experience a place's natural surroundings and learn about the ecology in a way not afforded by extreme games.

"Tree climbing is a slow activity," says Kovar. "It's not something you do quickly and then you're on to the next thing or event." There is no such thing as a quick climb, especially for beginners. This wasn't a race against the clock or the fellow climbers. In fact, tree climbing is unlikely to ever become a feature of the extreme games. Many climbers refuse competition. There has already been so much competition in the world.

"When you stand below the tree, it can be amazing," Rusel DeMaria says, looking affectionately up at Michael's Triumph, a 150-foot-tall tree. But reaching the treetop, he adds, is an entirely different feeling. Likewise, his wife, Viola Brumbaugh, kneels on the ground and asks Michael's Triumph for permission to climb. "It goes a lot smoother that way, "She says.

And climbing has been included into many educational programs. New Tribe offers guided climbs through its school, Tree Climbing Northwest, where "we teach enough tree biology and forest ecology to raise awareness in our students," says New Tribe present Sophis Sparks. "We know that the tree climbing experience deepens personal appreciation for trees. After climbing, people value trees more and are motivated to support preservation. This is not just to preserve their playground."

Perhaps that is why he struggles with the term "recreational tree climbing," saying, "I prefer to call it inspirational tree climbing."

1.What do slow travel and the slow food movement have in common?

A. They take people a long time. B. They are related to the eco-tourism industry.

C. They advocate protecting nature. D. They cost people little money

2.What do we know about tree climbing from the passage?

A. People compete to see who can climb to the top first.

B. It favors the experience of enjoying nature.

C. It is a kind of extreme sport and needs a lot of effort.

D. People view it as a challenge to climb the tallest tree in a forest.

3.Brumbaugh kneels on the ground before climbing trees to ___________________.

A. beg for the safety of climbing B. Expect to climb faster than her husband

C. Show respect for the tree D. ask for permission of her husband

4.Sophia Sparks prefers the term "inspirational tree climbing" because it ____________.

A. provide people with more chances to play outside

B. bring a lot of pleasure to life

C. Deepens personal love between each other

D. Makes people realize they should protect trees

5.What's the best title for the passage?

A. Tree-climbing travelling B. Slow travel movements

C. Dangers of climbing D. Respect for nature
