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．”

1.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．

2.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．

3.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．

D．People have adopted the four healthy habits after knowing they're good．

4.What would be the best title for this passage?

A．Smoking and Drinking Cuts You 14 Years

B．How to Live a Much Healthier Life

C．Healthy Habits May Give Extra 14 Years

D．How to Make Your Life Longer Than Others

It was a beautiful Sunday morning, and Maggie and I were returning from our walk through the woods．We were only a couple of blocks from home when I spotted a cell phone and a credit card sitting on the road．We took them home．We always find amazing things on the street and she looks upon them as a movable feast-a chicken wing here or a barbecue rib （肋骨）there．

I found another cell phone a few years back, too, and called a number in its phone book．I explained the situation to the guy who answered．He said it was his sister's and that he'd come to pick it up, which he did．

And that was that．No verbal thank-you, no written thank-you, no “here's a box of chocolates” thank-you．

I didn't have time to call anyone on my latest found cell phone．I was pouring myself coffee when it started to shake and dance across the kitchen counter．

“Who's this?” someone asked when I picked up．

“Who's this?” I countered（反问）．“Sarah?”

She was surprised at my knowing her name until she realized her name was on the credit card．“Could you send them to me?” she asked．

She lives in Arlington, which is 2 miles from my house．

“Hmm, no, ”I replied, adding that I thought she could come to get them, and that if I wasn't at home, they would be in my mailbox．

A day later, when I was out for a run, someone got them back．There wasn't even a piece of paper put in the mailbox with “Thanks” on it．In this age of e-mail and cell phone, there's really no excuse．Years ago, I found something more precious than a $100 bill on the street：a driver's license．I saw  that its owner lived a couple of blocks from me, so I called him up．He asked whether I could slip the license through his front door．

“I guess I could, ”I replied．

And that was that．

Broken rubber bands and flat tires requiring replacement could soon be a thing of the past．

French researchers have developed a new kind of rubber that can repair itself when broken．The new rubber is made from widely available materials including vegetable oil and a common industrial chemical．All the materials are considered safe to the environment and can be easily reused．

The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch．When cut, the rubber can be made new again, simply by pressing the two broken ends back together．

The product can be repaired at room temperature, around twenty degrees Centigrade；other self-healing materials require higher temperatures for repair．

Traditionally, rubber substances are made from huge molecules（分子）connected by strong chemical links, or bonds．The new rubber is made of smaller molecules．The molecules are linked together using hydrogen bonds．When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks（超分子网）．When the rubber is cut, the molecules attempt to connect with whatever molecule is near them．When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new．

However, time is an important element in the process．If the broken ends are not brought together quickly, a repair is not possible．This is because molecules will form bonds with molecules on their own side．The inventors say the surfaces of the rubber can be repaired within a week of being separated．

The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris．The organization is part of France's National Center for Scientific Research．The new material is described in greater detail in the research publication Nature．

 A very little boy was spending his Saturday morning playing in his sandbox. He had with him a plastic pail (桶) and a shiny, red plastic shovel (铲). In the   36   of creating roads and tunnels in the sand, he   37   a large rock in the middle of the sandbox.

The boy dug around the rock,   38   to move it off the dirt. At first, he wanted to carry it out of the sandbox with his hands; however, it was too heavy. Later, with much   39  , he pushed the rock across the sandbox by   40   his hands. When the boy got the rock to the   41   of the sandbox, he found that he couldn’t roll it up and   42   the little wall.   43  , the little boy pushed, but every time he thought he had made some   44  , the rock tipped (翻滚) and then fell back into the sandbox. The little boy pushed and pushed, but his only   45   was to have the rock roll back.

Finally he   46   tears. All this time the boy’s father watched from his living room window   47   the drama was unfolded. The moment the tears fell, a large   48   appeared across the sandbox. It was the boy’s father. Gently but   49  , he said, “Son, why didn’t you use all the strength that you had?”

Defeated, the boy   50   back, “I did! I did! I used all the strength that I had!”

“No, you didn’t. You didn’t ask me for help.” The father   51   down, picked up the rock and dropped it off the sandbox.

Do you have “rocks” in your life that need to be   52  ? Are you discovering that you don’t have   53   it takes to lift them? There is someone who is willing to give us the   54   we need. Maybe, it’s sometimes a good idea to ask others for   55   when we meet difficulties we can’t overcome.
