George Eberhardt turned 107 last month, and scientists would love to know how he and other older folks like him made it that far. So he's going to hand over some of his DNA.

He's one of 100 centenarians (百岁老人)taking part in a project that examines some of the oldest citizens with one of the newest scientific tools ： wholegenome sequencing (全基因组测试)，the deciphering of a person's complete collection of DNA.

Scientists think DNA from very old healthy people could offer clues to how they have lived so long. And that could one day lead to medicines to help the rest of us stay disease-free longer.

"It's very hard to get to 105 without some genetic advantages," says Dr Thomas Perls, a geriatrics(老年医学)expert at Boston University. Dr Perls is helping find centenarians for the Archon Genomics X Prize com?petition. The X Prize Foundation, best known for a space-flight competition, is offering up $ 10 million in prize money to researchers who decipher the complete DNA code from 100 people older than 100. The contest will be judged on accuracy, completeness and the speed and cost of sequencing.

Mr Eberhardt played and taught tennis until he was 94 and says he's participating in the X Prize project because he's interested in science and technology. It's not clear his genes will reveal much. Nobody else in his extended family reached 100， and he thinks only a cou?ple reached 90， he says in a telephone interview.

So why does he think he has lived so long? He attributes it to 70 years of marriage to his wife, Marie. She in turn cites his "intense interest in so many things" over a lifetime, from building radios as a child to pursu?ing a career in electronics research.

But scientists believe there's more to it, and they want to use genome sequencing to investigate. Dr Richard Cawthon of the University of Utah, who is see?king longevity genes by other means, says it may turn up genetic features that protect against multiple diseases or that slow the process of aging in general.

Every hour spent outdoors each week can reduce a child's chance of becoming short-sighted by two per cent. Children who are short-sighted spend an average of 3. 7 fewer hours a week outside compared with those who have normal vision, a study has found.

Short-sightedness runs in families and has also been linked to a host of factors. They include the amount of time spent focusing on near objects and levels Gf physical activity. But simply spending time out of the house may be enough to protect the eyesight. Being outdoors can reduce the amount of time that children spend in reading or playing computer games, researchers said.

Between 15 and 20 per cent of British people are short-sighted, but the problem is much more serious in parts of East Asia. There, as much as 80 per cent of the population is short-sighted. One ?tudy compared children living in different countries. It found that those in Australia had better vision on average than people of the same age in China and Singapore. The Australian group read and achieved as much as those in other countries, but they were found to spend more time outdoors.

Dr Sherwin, one of the researchers who did the study, said the benefit from being outdoors could be linked to increased UV radiation(紫外线辐射）.Short?sightedness is caused by having longer eyes and some studies have shown that some chemicals affected by UV rays may control the length of the eye. A lack of sunlight could make such chemicals grow too much, he explained.

He said, "It could be caused by not enough UV radiation, and it could also be caused by spending less time looking into the distance or not enough physical activity.”

1. What is the main idea of the passage?

A. Children's short-sightedness can be cured.

B. There are several causes of children's short?sightedness.

B.     Not taking part in enough physical activities.

C.     Spending little time looking into the di.stance.

Many people have influenced various aspects of my life, based on their personal characteristics, accomplish?ments, and values. I have been fortunate to have had numerous teachers and professors who I respect for their patience and intelligence. There are artists that have inspired me by their natural talents and original creativi?ty. I value many political leaders, who have inspired me by their contributions to society, and their abilities to change our futures. But of all the people I have known in my life, the person I admire most is my father.

As the youngest girl in my family* I always consid?ered myself to be "Daddy's little girl". While I grew up, it always made me sad to see so many of my friends and neighbours without a father or father-like figures around. This helps me appreciate how my father always takes an interest in his children's lives. In every aspect of my life my father continuously pushes me to excel, so I could accomplish my work outstandingly among my people. Whenever I feel like giving up, or have a ques?tion or a concern, I know I can always call on him for advice. From him I have also learned that sometimes you have to put others' needs ahead of your own, but you should make sure you are not taken advantage of by others. His strength seems to be unbreakable during hard times, and he is extremely determined to accom?plish anything he sets his mind on, no matter how tiny it is. I highly respect him for how he stands up for what he believes in, and will never back down. I have always admired his open mind, compassion for people, and sense of understanding. He is a very reserved man, but to everybody's surprise, he has a great sense of hu?mour, and always knows how to put a smile on the faces of his wife, his children and his friends.

Living in his affection and instruction, I am very proud of my father. He also professes how proud he is of his children, and is still there to support us in what?ever we are involved in.

If you have decided to lose the extra pounds, then you surely know that the only way to do that is by combining workouts with a healthy, balanced and nutri?tious diet. However, there are some types of drinks that will speed up the fat burning and help you lose weight quicker than you normally would, and here you will find

2 of the most efficient ones ：

Green tea has been used for hundreds of years due to its numerous benefits, and weight loss is just one of them―although green tea alone will only help you lose a few pounds? it will certainly serve as a great addition to your diet in the long run. Drinking one cup of tea per day will deliver all the antioxidants(抗氧化剂)you need and it will also help you burn fat at a faster pace by promoting the metabolism (新陈代谢).These teas are perfect for burning more calories as well as for increas?ing your overall energy levels and for suppressing your desire to eat. These teas help you remove the extra pounds by suppressing your desire to eat, thus decrea?sing the amount of food you would normally consume every day. Green tea is said to also help you reduce stress and relax better.

Fruit juices are delicious, easy to prepare and very rich in nutrients, vitamins and minerals―besides this, there are literally hundreds of different fruits you can choose from, and pears and cranberries(越橘)are only two of the most delicious, most efficient and most popular ones given the fact that they contain high amounts of vitamin C. Not only will the cranberry and pear juices help you lose weight by promoting your me?tabolism ,but they will also increase your overall energy levels and deliver your body all the essential vitamins and proteins that it so much needs. Meanwhile, it is known that the cranberry juice is essential for preven?ting various infection of the bladder (膀腕).What's more, pears contain mineral substances and are essential for a healthy lifestyle, not to mention that they are rich in vitamin C and calcium, the latter being particularly important for keeping your bones healthy and strong.
