A robin may be the first ________ of spring．
DSince the gene, called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging, immunity(免疫)and resistance in humans, the scientists said.?“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,” said Robin May of the University of Birmingham, who led the study.?Populations across the world are aging at a surprising pace, bringing potentially big challenges for health and social care systems. A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays. Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.?“What we have found is that things like resistance and aging tend to go hand in hand,” May said in an interview.?May’s team compared longevity, stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAF-16 in each of the four species, and found that they were all quite distinct.?May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes, which scientists believe play a role in the aging process.?“The fact that subtle（微妙的）differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution,” May said.?71. In which section may the text appear in a newspaper? ? A. Education. B. Science. C. Entertainment. D. Culture. 72. According to May_________,.?A. resistance has a lot to do with aging? B. FOXO genes can be found in worms?C. genes play the same role in different species?D. new drugs will change the genes in older people73. What can we know from the third paragraph??A. New ways have been found to affect aging. ?B. Babies in the rich world will all live longer. ?C. Present social care systems are poorly managed.? D. Aging populations are causing more challenges.74. From the text we know that DAF-16.?A. is a gene that is only found in worms? B. can make people live longer?C. has an effect on aging and immunity? D. has been quite familiar to scientists75. What can be the best title of the passage?A. Scientists Find Gene Linked to Aging B. Population Aging Faster than ExpectedC. How to Make People Live Longer D. Gene Determines How Long We Live

Some people believe that a Robin Hood is at work, others that a wealthy person simply wants to distribute（分发）his or her fortune before dying. But the donator who started sending envelopes with cash to deserving causes, accompanied by an article from the local paper, has made a northern German city believe in fairytales（童话）.
The first envelope was sent to a victim support group. It contained ?10,000 with a cutting from the Braunschweiger Zeitung about how the group supported a woman who was robbed of her handbag; similar plain white anonymous（匿名）envelopes, each containing ?10,000, then arrived at a kindergarten and a church.
The envelopes keep coming, and so far at least ?190,000 has been distributed. Last month, one of them was sent to the newspaper’s own office. It came after a story it published about Tom, a 14-year-old boy who was severely disabled in a swimming accident. The receptionist at the Braunschweiger Zeitung opened an anonymous white envelope to find 20 notes of ?500 inside, with a copy of the article. The name of the family was underlined.
“I was driving when I heard the news,” Claudia Neumann, the boy’s mother, told Der Spiegel magazine. “I had to park on the side of the road; I was speechless.”
The money will be used to make the entrance to their house wheelchair-accessible and for a course of treatment that their insurance company refused to pay for.
“For someone to act so selflessly, for this to happen in such a society in which everyone thinks of himself, was astonishing,” Mrs. Neumann said. Her family wonder whether the donator is a Robin Hood character, taking from banks to give to the needy.
Henning Noske, the editor of the Braunschweiger Zeitung, said: “Maybe it is an old person who is about to die. We just do not know.” However, he has told his reporters not to look for the city’s hero, for fear that discovery may stop the donations.

3.It can be inferred from the passage that .
A. the donation will continue to come

“What we have found is that things like resistance and aging tend go hand in hang “ May said in an interview
May’s team compared longevity ,stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAV-16 in each of the four species and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes , which scientists believe play a role in the aging process. “The fact that subtle differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and many explain how differences in lifespan and related traits have arisen during evolution，”May said
1.In which section may the text appear in a newspaper?

2. According to May ,
A resistance has a lot of to do with aging B FOXO genes can be found in worms
C genes play the same role in difference species D new drugs will change the genes in older people
3.From the text we know that DAF-16
A is a gene that is only found in worms B can make people live longer
C has an effect on aging and immunity D has been quite familiar to scientists
