throughout history, many famous faces have battled diseases before, during, or after they made a name for themselves. lou gehrig lou gehrig had his baseball career cut short by amyotrophic lateral sclerosis (als). examination of rawhide a movie starring (由主演) lou gehrig showed that he still functioned normally in january 1938. however, the diagnosis of als was soon confirmed a year later. he was so loved and well-known that als became known worldwide and the disease is now commonly referred to as “lou gehrigs disease”. muhammad ali in 1984, arguably the greatest boxer in history was diagnosed with parkinsons disease, a condition affecting the central nervous system. however, ali continues to remain as active as possible, lighting the torch at the 1996 summer olympics and attending president barack obamas inauguration (就职典礼). he has also been an activist for parkinsons research and set up the muhammad ali parkinson center in 1997.wilma rudolph wilma rudolph was considered as the fastest woman in the world after winning three gold medals in track-and-field in the 1960 olympics. what makes people more surprised was that she was paralyzed (使瘫痪) by the poliovirus as a young child. she eventually recovered, but her left foot was slightly disabled. by the time she was 12, she had also survived several other serious illnesses. kareem abdul-jabbar in november, 2009, kareem abdul-jabbar, who was named one of 50 greatest players in nba history, announced he had chronic myeloid leukemia, a slow-growing cancer of the white blood cells. he had been

began making bracelets (手链) when she was six. family and friends loved her designs and asked for more. when admirers suggested that raeann sell her bracelets, she realized she wanted to do just that and donate the money to help kids with special needs, like her brother derek.raeanns older brother, derek, has cri du chat syndrome. children with cri du chat usually have problems understanding ideas and might have a hard time learning to talk. many also have weak muscles (肌肉) that can cause problems with walking or using their fingers to pick things up. the term cri du chat means “cry of the cat” in french. babies with cri du chat often have a high-pitched cry that sounds like that of a little cat.over the years, dereks teachers helped him learn sign language and gestures. they also taught him skills such as recognizing letters, cutting with scissors, and understanding basic math. raeann wanted to donate money to dereks school. “i just wanted to help my brother,” she says, “and the people who help him.”at first, raeann focused on creating jewelry that would raise awareness for cri du chat. but people started requesting bracelets to wear as a symbol of support and awareness for a variety of other diseases and disorders. to create those symbols, raeann researched the color most often associated with raising awareness for the disease or disorder, such as pink for breast cancer or orange for leukemia.in the end, it turned out to be a great idea. in only a few years, raeann has donated more than $30,000 to local charities. raeanns mom says that working on the bracelets has developed the generosity and kindness that already existed in her daughter. raeann plans to keep making bracelets and raising dollars for charities. “i just want to keep going on with it,” she says,

people of all ages for more than one hundred years. the russian word for the doll is “matryoshka”, the traditional design being that of a young russian woman dressed in russian native costume with a scarf on her head. the first four letters, “matr” is the russian word for mother. so the nesting doll represents both the national motherland and actual motherhood and fertility (生育力). this explains why the traditional set is painted like women, ending with the smallest a baby. nesting dolls are typically all the same cylindrical (圆筒状的) shape, yet painted as many different characters. they are made into father christmas, easter bunnies with eggs, political figures, animals, career dolls, disney figures and more, the favorite being the traditional family of nesting dolls. the number of a set of dolls is usually 5 or more, decreasing in size, placed one inside the other, usually ending with the innermost doll of a baby which does not open. in some sets of 12 or more, the smallest can be so tiny that a magnifying glass (放大镜) has to be used for painting the faces.these dolls are the most famous russian national souvenir; however, they did not originate from the country which made them popular. sergei maliutin, a painter from russia who worked at a folk craft workshop, saw a set of japanese wooden dolls representing the seven gods of fortune in 1890. this inspired him to create his own set of eight dolls, consisting of the outermost being of a girl holding a rooster, five inner girl dolls, one boy doll and the smallest, a baby.the russian nesting dolls were then shown at the world exhibition in paris and they earned a bronze medal. afterwards, other craftsmen in russia began making these dolls. now they can be found in craft shops and online stores. if you find yourself in a quandary as to what to get someone as a gift, just consider the russian nesting dolls.58. how is paragraph 2 mainly developed?a. by analyzing causes. b. by following time order. c. by giving descriptions. d. by making comparisons. 59. which of the following sets of nesting dolls was made by sergei maliutin?60. the underlined part “in a quandary” in the last paragraph can best be replaced

of “matryoshka”d. an introduction to russian nesting dollsd the first ever human head transplant (移植) is now possible. dr. sergio canavero believes that the technology now allows doctors to carry out the frankenstein-style procedure, which has been tested out on animals since 1970. up until now there has been no way to successfully reconnect the spinal cord (脊髓), leaving the subjects paralyzed from the point where the transplant was connected.recent advances have meant that reconnecting the spinal cord is now possible, and it is believed that the breakthrough means that previously deadly diseases could be cured. however, other experts cannot accept the idea. professor anthony warrens, from the british transplantation society, said, “connecting a head to a body is impossible for human beings today. the whole idea is bizarre.”in 1970 robert white successfully transplanted the head of a rhesus monkey (恒河猴) onto the body of a second rhesus, and dr. sergio canavero, a member of the turin advanced neuromodulation group, has suggested a similar method. “the greatest technical difficulty in such an attempt is of course the reconnection of spinal cords between two creatures. it is my opinion that the technology only now exists for such linkage,” he said. “it is argued that several up to now hopeless medical conditions might benefit from such procedure.”he believes that a team of 100 could perform the operation in 36 hours at a cost of 8.5 million. both heads would have to be removed at the same time, and reconnected within an hour. “this is no longer science fiction. it could be done today now. if the operation is done it will provide a few people with a great amount of extra life,” he said. “the only reason i have not gone further is lack of a huge amount of money for the operation.” however, dr. calum mackellar, from the scottish council on human bioethics, added, “this sounds like something from a scary movie.”62. what has been the key to human head transplant?a. the choosing of human heads.b. the reconnection of spinal cords. c. lack of a huge amount of money.d. strong disagreement of the public.63. the underlined word “bizarre” in paragraph 2 probably means _.a. exciting b. clear c. strange d. unpleasant64. robert whites experiment on rhesus monkeys shows _.a. the possibility of reconnecting the spinal cordb. the difference between animals and humansc. a breakthrough in human head transplantd. some unsolved technical difficulties65. the last but one paragraph mainly talks about _.a. the operation of human head transplantb. the development of transplant technologyc. how to perform the operation successfullyd. whether the operation is worth performing第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。headachesa
