A super drug that could remove Alzheimer's(痴呆症) ，heart disease and diabetes(糖屎病) and help people live to 100 is being developed by scientists. Their research is based on the iden?tification of three genes that improve long and healthy lives and prevent diseases of aging. Medi?cally controlling the proteins made by the " longevity genes" will allow millions to live longer, predicts Nir Barzilai.

Those people whose DNA strongly features the three genes are 80 percent less likely to de?velop Alzheimer's. The genes also fight against the deadly impact of smoking, bad diet,obesity and lack of exercise.

Already，several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage the old people. "The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing," he said. "The biology we're trying to uncover is that if we can imitate that,long life can be really terrific."

Of the three longevity genes, two increase the production of so-called good cholesterol(胆固醇) ，which reduces the risk of heart disease. The third prevents diabetes. They were discov?ered by Dr Barzilai's team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the study group―which shared relatively few common ancestors―was 20 times more likely to hit the century. Dr Barzilai said, "Thirty percent of them were overweight and 30 percent smoked two packs of cigarettes a day for more than 40 years,however they could still live to 100."

But Andrew Ketteringham, of the Alzheimer's Society, said. " Alzheimer's disease, a most common disease, is likely to be caused by a combination of genetic disposition(遗传倾向) ，lifes?tyle and life events. Many genes are probably involved.”

A. magical medicine B. three special genes

C. having no disease D. once being sportsmen

( ) 2. Why does the discovery of the longevity genes mean a lot?

One Saturday morning after breakfast, I returned to my dormitory and saw the house parent chasing the beautiful butterflies, hundreds of which lived in the bushes around the orphanage. I carefully watched as he caught these beautiful creatures, one after another, and then took them from the net and stuck straight pins through their head and wings,pinning them onto a heavy cardboard sheet.

How cruel it was to kill something of such beauty. When the house parent went inside to answer the phone, I walked up to the cardboard and looked at the butterfly that he had just pinned to the large paper. It was still moving about, so I reached down and touched it on the wing,causing one of the pins to fall out. It started flying around and around, trying to get away but it was still pinned by one wing with another straight pin. Finally its wing broke off and the butterfly fell to the ground, still trembling. I tried to let it fly away before the house parent came back. But I failed.

When the house parent came back,he was angry with me though I didn't admit doing any?thing. He picked up the cardboard paper and started hitting me on the head. There were all kinds of butterfly pieces going everywhere. He threw the cardboard down on the ground and told me to pick it up and put it in the garbage can inside the back room of the dormitory and then he left. I sat there in the dirt for the longest time trying to fit all the butterfly pieces back together so I could bury them whole, but it was too hard to do. So I prayed for them and put them in an old torn-up shoebox and I buried them in the ground near the blackberry bushes.

Every year when the butterflies would return to the orphanage and try to land on me,I would try and shoo them away because they did not know that the orphanage was a bad place to live and a very bad place to die.

Jamie Carrion took her four-year-old daughter，Averie and her little son，Abel into her father's truck and began driving from her parents' home to her home several hours away. But,she hadn't realized how icy the roads were. Just a few miles into the drive,the truck rolled over several times and landed on the passenger side.

While the family warmed the shivering(发抖) child up with blankets, Zenk's father Patrick got into his truck to see what had happened. Just down the road,he came across a group of e-mergency vehicles, and a female driver crying. Police officers were searching for Averie in the snowy fields. "I think we have what you're looking for.
