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.

Thousands of people living in the Chinese capital will celebrate the start of the Chinese New year by heading for the ski resorts (滑雪场). Never mind that Beijing's dry weather seldom produces snow. It is cold enough in winter for snow-making machines to make a covering for the hills north to the capital. And the rapid growth of a pleasure-seeking middle class has formed t
he basis for this new craze(热潮）
Since Beijing's first ski resort was opened ten years ago, the sport has enjoyed astonishing increase. There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr. Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that
could soon lead Chinese to head for the ski resorts of Europe, In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can't really match the equipment and services of some ski resorts in Europe.
Beijing's skiing craze is partly a result of the recent increase in private (私有的) cars. This has led to the growth of a leisure industry in the capital's suburbs (郊区), which until the late-1990s were unreachable to ordinary people, According to Mr. Wei, about 40% of the visitors to his resort come in their own cars. The rest are bused in by schools, businesses or government offices.
The problem is making money. Starting ski resorts requires quite a lot of money; hiring land from the local government, preparing the hills, buying snow machines, making sure there are enough water and electricity to run them, and buying ski equipment for hiring out to customers.
The ski resort where Mr. Wei works cost nearly $4 million to set up. And. as so often in China when someone comes up with a good idea, many others rush in and price wars break out. Beijing now offers some of the cheapest ski training classes in the world, though with most people rather new to the sport, expecting a few more doing the same job.What does this text mainly talk about?
| A．Convenience for skiers brought about by private cars. |
| B．Skiing as a new way of enjoying one's spare time. |
| C．Things to be considered when starting a ski resort. |
| D．A sudden increase of ski training classes in Beijing. |
Why are some Chinese likely to go skiing in Europe?
| A．To visit more ski areas. | B．To ski on natural snow. |
| C．For a large collection of ski suits. | D．For better services and equipment. |
The underlined words "leisure industry" in Paragraph 3 refer to ----
A. transport to ski resorts B. production of family cars
C. business of providing spare time enjoyments D part-time work for people living in the suburbs What is the main problem in running a ski resort?
| A．Difficulty in hiring land. | B．Lack of business experience. |
| C．Price wars with other ski resorts, | D．Shortage of water and electricity, |

Chinese people are now living happier and longer than before. According to the latest study, the number of people over 60 years old is 130 million, making up 10 percent of the whole population, and increases at a rate of 3 percent per year. This marks that China has stepped into the aged society. It is the Chinese tradition to respect, love, support, and help old people, and the aging problem has received more and more attention from the society.
China has built the system to protect and serve old people’s legal (法律的) rights and interests, gradually developed social insurance, public health services and social welfare (福利) projects for old people, and als
o applied the minimum living standard protection (最低生活保障) system for the aged who are unable to work and receive no supports. Now, China is bringing the aging problem into the work of sustainable (持续的) development according to China’s conditions, to build and develop a social security system for old people, set up a system combined with the state, collectives (集体) and families to solve the problem of “the elderly should be provided for”. The life of China’s old people is more colorful along with the fast and sound economic development of the country.
Old people in today’s China who don’t have to consider their food and clothing hope to live more colorfully. The happy psychology (心态) of the aged makes them thir
sty for knowledge. Strong and healthy old people can be seen everywhere of the country. They learn new knowledge, surf the Internet, practice handwriting and drawing, and take part in fashion shows, exercises and entertainments. Their active and sound living attitude encourages the youth around and they are in fact an important role in ensuring a stable and peaceful society.The underlined part “thirsty for” (in the last paragraph) means “________”.
