are breastfed by infected mothers catch the virus. tests show, though, that hiv is indeed present in breast milk, so these 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 and, 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 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 potentially 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 fractions, 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 to 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 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 changes 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 transmission 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.63. what is the main idea of paragraph 1?a. the breast milk from 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 frequently.64. 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.65. which of the following about tenascin c is true?a. it has become an effective tool 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.66. what can we know about permar and her research group according to the passage?a. they have found a 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.【参考答案】63. b64. d65. d 66. c阅读下列短文，从每题所给的a、b、c和d项中，选出最佳选项，并在答题卡上将 该项涂黑。abraham lincoln was born

his breathlessness.“thats better,” mallon said. “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 to 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 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 harder 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 shouting. 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 the 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.

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 in 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, sendinga 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 pulled 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 on mallon and turned and put his hands on the steering wheel. he raised his eyes to the rearview mirror and he and mallon exchanged stares.“o.k., mr. american,” he said. “you pay.”67. what does the underlined sentence in paragraph 2 indicate?a. mallon shouldnt have saved the pickpocket.b. the pickpocket didnt thank mallon for his offer.c. the pickpocket blamed mallon for his failure to steal.d. mallon must have beaten the pickpocket before helping him.68. where should the

drop out of school and report twice as much alcohol and tobacco use than their single classmates, according to new research from the university of georgia.romantic relationships are a trademark of adolescence ，but very few studies have examined how adolescents differ in the development of these relationships, said pamela orpinas ，study author and professor in the college of public health and head of the department of health promotion and behavior.orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. their teachers completed questionnaires (调查表）about the students* academic efforts. he found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. other students dated infrequently in middle school but increased the frequency of dating in high school.at all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,1 according to the journal article. study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters.dating a classmate may have the same emotional complications of dating a co-worker, orpinas said, when the couple break up. they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. it is reasonable to think this could be linked to depression and divert (转移）attention from studying.”4tdating should not be considered a ceremony of growth in middle school，”orpinas concluded.41.according to the passage, students who date in middle school may_a. have poorer academic performances b. be more likely to hurl othersc.enjoy better school livesd. are less likely to use alcohol and tobacco【答案】a【解析】细节理解题。根据students who date (约会）in middle school have significantly worse study skill
