A healthy amount of sunshine may be the secret to staying young. British scientists have discovered.

Vitamin D is produced naturally by the skin in response to (¶Ô¡­µÄ·´Ó¦) 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 become more susceptible (Ò×ÊÜÉ˺¦µÄ) to certain 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 show 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."

Professor Tim Spector, a co-author of the report, added, " Although it might sound absurd(»ÄÌƵÄ), 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 percent of the body's supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals(Öà).

Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.

We are often unable to pay close attention to what we hear. Just like when we try to grab a sponge(º£Ãà) that is full of water, some water will run out of it. But sometimes we try to remember everything a speaker says and try to take in a speaker¡¯s every word as if every word was equally important. We try to remember all the names, all the dates, and all the places. In the process we often miss the speaker¡¯s main point.

Erik Waldman works at a design company. Knowing he had never been good at budgeting his money, he was determined to begin thinking about his economic future. When his employer circulated an e-mail announcing a financial planning workshop(ÑÐÌÖ»á), Erik signed up right away.

The first session was about retirement planning. Simone Fisher, the lecturer, explained that 7 of 10 Americans between the ages of 22 and 35 do not have a regular savings plan. Erik wrote down every number Simone mentioned.

"If you want to have a retirement income equal to 75 percent of your current salary," Simone continued, "you will need to save at least of 6 percent of your present earnings, taking into account future inflation rates(ͨ»õÅòÕÍÂÊ). In the meantime, I want to stress that the most important thing is to start saving now."

Erik recorded all the statistics Simone used. When she opened the floor(×ÔÓÉ·¢ÑÔ) for question, Erik raised his hand and said, "I have two question. When is the best time to start saving for retirement? And how can I figure out my savings target if I don¡¯t know what inflation rates will be in the future?"

This is a typical example of losing the speaker¡¯s point by concentrating on details. Erik had fixed his mind on remembering all the statistics in Simone¡¯s presentation, but he blocked out the man message. Rather than trying to remember everything, we should concentrate on main ideas and evidence.

1.What does the author mean by saying "Just like when we ... run out of it."?

A. We tend to reject what others say.

B. We always try to remember all details.

C. It is difficult for us to remember all things.

D. We often fail to focus on what we are listening to.

2.During the workshop, Erik .

A. got Simone Fisher 's main idea

B. focused on the lecture's details

C. showed little interest in the lecture

D. didn't agree with what Simone had said

3.When hearing Erik's questions, Simone would most probably think .

A. they are very good questions

B. Erik was an excellent listener

C. it was hard to answer the questions

D. his questions were meaningless

4.The passage is written to help those who want to be .

A. a good listener B. a financial planner

C. an excellent lecturer D. a successful employee

A kind father lost about 57 kg in just six months after being shamed dieting when he became too fat to play with his young daughter. Chris Willis, 47, tipped the scales at 172 kg following a lifetime of fatty foods. But overweight Chris turned to dieting when he realized he was too fat to play with his ten-year-old daughter, Sophie, who had a passion for running.

The determined dad cut out all the fatty foods he had enjoyed, and began exercising. He now weights 105 kg after losing 10 kg every month since July. Chris, who lives in Shepreth. Cambridgeshire with his wife Jackie. 51, a coach driver, said: ¡°The hardest thing was seeing my little girl in the garden and not being able to join in because I was so unhealthy. But now I am making up for lost time---we do so much together and it is just great.¡±

Chris used to consume an incredible 5,000 calories a day, before he switched to healthy lifestyle. On average he would eat five slices of bread for breakfast as a mid morning meal before a full English breakfast. He would then eat a sandwich, a large pack of crisps and a pasty for lunch before chewing a whole packet of biscuits in the afternoon. For dinner Chris would demolish a curry(¿§·È) and, ice cream, and also drink four pints of beer very quickly, before feeding on fatty snacks all evening.

Amazingly Chris claims he still eats the same amount---but has simply cut out the unhealthy fatty foods. Chris said: ¡°'My family and friends have been so supportive and my wife and daughter are so pleased for me. In fact it¡¯s them I did it for more than anyone else. The whole journey has been amazing and I am still shocked myself that I have managed to lose so much weight.¡± Chris is now aiming for a new target weight of 96 kg.
