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.

Subway transfer

“Transfer” is a word frequently used by volunteers helping visitors choose the best way of transport during the ongoing Beijing Olympics to save time.

On the seven subway lines now in operation, the transport authorities have set up a total of 16 transfer stations:

Transfer between Line 2 and Line 1 at Jianguomen and Fuxingmen stations；Transfer between Line 2 and Line 5 at Chongwenmen and Yonghegong stations;

Transfer between Line 2 and Line 13 at Dongzhimen and Xizhimen stations; Dongzhimen station can also bring you to Beijing Capital International Airport via the Airport Line；

Transfer between Line 1 and Line Batong at Sihui and Sihuidong stations；

Transfer from Line 1 to Line 10 at Guomao station to reach Zhongguancun, the north Third Ring Road (going north and west) or Jinsong (going south).

Via Line 10, transfer to Line 8 at Beitucheng station to reach the Olympic central zone, where the “Bird’s Nest” and other venues are located; transfer to Line 5 at Huixinxijie Nankou; transfer to Line 13 at Zhichunlu and Shaoyaoju stations; Sanyuanqiao station takes you to the airport via the Airport Line.

China news, Beijing, Feb. 9 – Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.

    Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US.

    The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?

     At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate(控制) the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.

What is the average housing price per square meter in China?

     A. 8000 yuan      B. 10000 yuan       C. 7000 yuan      D. It’s not mentioned here

Which of the following does NOT support the idea that the average housing price in China

  is even higher than in the United States?

    A. Chinese houses can not be compared with houses in US in terms of building quality,

  environment and supporting facilities.

    B. American people’s average income is several dozen times higher than that of Chinese

 people.

    C. The houses in US are not sold in terms of building area, as most Chinese property

 developers do when they sell their houses.

    D. There are more people who need houses in China.

What is the main idea of this passage?

    A The housing price in China is so high that the government should do something useful to

 prevent it.

    B. There are some bubbles in Chinese real estate market

    C. The average housing price in China is even higher than in the United States

    D. Chinese government issued a set of policies that aimed to benefit the public.

How many measures are mentioned in the last paragraph in order to reduce the high housing

 prices?

    A. Four               B. Three                C. Five                  D. Two
