17、lores C. Jerusalem CME Church D. Ezkiel W. Cullen HouseB For decades, public health officials have puzzled over a surprising fact about HIV: Only about 10-20 percent of infants who are breastfed by infected mothers catch the virus. Tests show, though, that HIV is indeed present in breast milk, so th

18、ese children are exposed to the virus multiple times daily for the first several months of their lives.Now, a group of scientists and doctors from Duke University has figured outwhy these babies dont get infected. Human breast milk naturally contains a protein calledTenascin Cthat neutralizes HIV an

19、d, in most cases, prevents it from being passed from mother to child. Eventually, they say, the protein could potentially be valuable as an HIV-fighting tool for both infants and adults that are either HIV-positive or at risk of contracting the infection.The research, published inProceedings of the

20、National Academy of Sciences, was inspired byprevious workby other researchers showing that, both in tissue cultures (组织培养) and live mice, breast milk fromHIV-negativemothers was naturallyendowed withHIV-fighting properties. Scientists suggested that a few different proteins in the milk could potent

21、ially be responsible, but no one knew which one.As part of the study, the researchers divided breast milk into smaller fractions (部分) made up of specific proteins via a number of filters (过滤) separating the proteins by size, electrical charge and othercharacteristicsand tested which of these fractio

22、ns, when added to a tissue culture, prevented the cells from being infected by HIV. Eventually, theyfound that one particular protein was present in all the HIV-resistant fractions but in none of the others: Tenascin C.Tenascin C works by blocking a key protein onHIVs envelopethat normally ties up t

23、o a receptor on a T cells membrane called CCR5. In doing so, Tenascin C prevents HIV from mixing with the T cell and injecting its RNA inside.Still, the researchers say that other natural elements in milk might play a role in fighting HIV as well. “Its clearly not the whole story, because we do have

24、 samples that have low amounts of this protein but still have HIV-neutralizing activity,” the studys lead author Permar says.“So it may be actingin concert withother antiviral and antimicrobial factors in the milk.”Whatever those other factors are, though, the finding vindicates (证明的正确) recent chang

25、es toUN guidelinesthatrecommend even HIV-positive mothers in resource-poor countries should breastfeed, if theyre taking anti-retroviral drugs to combat their own infection.The next steps, Permar says, are determining which area of Tenascin C is active and whether it can effectively prevent transmis

26、sion in a live animal. If it works, it could potentially beincorporated(合并) into an HIV drug with broader applications. Its evenpossiblethat it could someday be adapted to reduce the risk of HIV transmission in adults as well as infants.19. What is the main idea of Paragraph 1?A. The breast milk fro

27、m an infected mother doesnt contain HIV at all.B. Its less likely for infants feeding on infected mothers breast milk to catch HIV.C. The possibilities of infants catching HIV have nothing to do with infected mothers.D. Children breastfed by infected mothers wont catch HIV though exposed to it frequ

28、ently.20. Why did the researchers divide breast milk into smaller fractions?A. To find out Tenascin C.B. To make up specific proteins.C. To add them to a tissue culture.D. To test what prevents cells being infected.21. Which of the following about Tenascin C is true?A. It has become an effective too

29、l in fighting HIV.B. It was first found by Permar and her research group.C. It can prevent transmission in a live animal effectively.D. It can sometimes prevent mother-to-child transmission of HIV.22. What can we know about Permar and her research group according to the passage?A. They have found a

30、cure for HIV.B. They have helped changeUN guidelines.C. They will do more researches on Tenascin C.D. Their finding is based on their previous work.CHe leant down to the pickpocket. The heaving and gasping had stopped, but he was still making a show of his breathlessness.“Thats better,” Mallon said.

31、 “Can you stand up? Try to stand up. Here,” he said, and gripped the pickpockets arm and forced him upright until he saw his face for the first time. As the pickpocket labored for breath, he gazed up at Mallon with his dark eyes.“How could you?”they asked.Mallon might have said, “Because you tried t

32、o steal from me.” But he was still conscious of the flush of joy hed felt when his blow struck home when he knew hed hurt the man. Where that joy came from he couldnt say, but he knew that its roots were deeper than some clumsy failed theft.Fat drops of rain began to patter on theawning(雨篷).“How are

33、 you?” Mallon said. “Can you walk?” The pickpocket turned away and leant against the store window with both hands, and his head sank lower as his shoulders rose and fell. A gray-haired woman inside the store rapped on the glass and made a shooing motion. When the pickpocket ignored her, she rapped h

34、arder and kept rapping.“I have to go,” Mallon said. “Im sorry.” He looked up at the sky. “Im sorry,” he said again, and stepped into the rain and walked quickly up the street.One of the Bangladeshi umbrella sellers was working the corner, and Mallon had just paid seven euros when he heard a woman sh

35、outing. He didnt want to look back but did. It was the woman from the shop, pushing and batting the pickpocket away from the window while he bent down and covered his head like a boxer trying to get through the last seconds of a round. Mallon slipped his wallet back into his jacket pocket and took t

36、he umbrella that the Bangladeshi had opened for him.The pickpocket was out on the sidewalk now, in the rain. The woman stood just under the awning with her arms crossed over her chest.“Excuse me, madam,” Mallon said, coming up to them. “This man isnt well. He needs to rest a moment.”“I know these pe

37、ople,” she said. “Our Romans dont want them here.”The rain fell in sheets, ran down the pickpockets shinyscalpand face, down his leather jacket.“Here,” Mallon said, and offered him the umbrella, but he only looked at Mallon with his hurt dark eyes and then lowered his head again. Mallon bumped him i

38、n the shoulder with the handle of the umbrella. “Go on take it!” he said. And finally, with a beaten, unwilling look, the pickpocket did.And that was when he saw a taxi round the corner with a light glowing on its roof. Mallon ran out waving his arm and the cab turned sharply to the pavement, sendin

39、ga lot ofwater over his shoes. He opened the door but couldnt help looking back. The pickpocket had lowered the umbrella to the ground upside down and was leaning on theshaft, head low, neck bared to the sky.“Wait,” Mallon said to the driver. He went back and grabbed the pickpockets sleeve and pulle

40、d him to the cab. “Get in,” Mallon said, and took the umbrella and pushed him into the back seat. He leaned inside. “O.K., where do you live?”“No Gypsies!” the driver said. He was twisted around, glaring at the pickpocket.“Gypsy? Look, hes not well. Ill pay,” Mallon added.The driver shook his head. “No Gypsies. Get him out,”Mallon looked at the drivers nameplate: Michele Kadare. “Its the law,” he said, “If you dont take us, Signor Kadare, Ill report you and youll lose your license. Believe me I am quite serious.”The driver fastened those pale eyes o
