Question

15．Darek Fidyka，a 38-year-old Bulgarian，had been paralyzed （瘫痪的） from the chest down for four years after a knife attack．Scientists from Britain and Poland took cells from his nose，transplanted （移植） them into his back and re-grew his spinal cord （脊髓）．Now he can walk and even drive a car．The doctors were delighted but said it was the first step in a long journey．
The breakthrough came after 40 years of research by Professor Geoff Raisman，who found that cells had the possibility to repair damage to nasal （鼻腔的） nerves，the only part of the nervous system that constantly re-grows．"The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself，"Professor Raisman said．
Polish doctors injected （注射） the nasal cells into Mr．Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue．The nasal cells appear to have caused the spinal nerves to repair themselves．
Professor Raisman achieved this with rats in the late 1990's，but this is his greatest success．"I think the moment of discovery for me was Christmas in 1997 when I first saw a rat，which couldn't control its hand，put its hand over to me．That was an exciting moment，because I realized then that my belief that the nervous system could be repaired was true．"
Doctors chose the easiest case for their first attempt-it might not work for others．But there is real sense of hope that an idea once thought impossible has been realized．
David Nicholls，who helped provide money for the breakthrough，said information about the breakthrough would be made available to researchers across the globe．
"What you've got to understand is that for three million paralyzed people in the world today，the world looks a totally brighter place than it did yesterday，"he said．
22．Why did Professor Geoff Raisman choose cells from nose？A
A．The nervous system in the nose can repair itself．
B．Cells from the nose can be easily transplanted．
C．The nervous system in the nose has more cells．
D．Cells in the nose are able to re-produce rapidly．
23．How did the operation work for Darek Fidyka？D
A．The nervous system in the spinal nerves can repair itself．
B．The nerves from his ankle cured the patient of the injury．
C．The nasal cells re-produced and spread over very quickl y．
D．The nasal cells helped the spinal nerves to repair themselves．
24．What made Professor Geoff Raisman begin to believe the nervous system can be repaired？D
A．His former study with other people．
B．His operation on a paralyzed patient．
C．His sudden thought about Christmas．
D．His unusual experience with a sick rat．
25．David Nicholls'words suggest thatB．
A．the world will become a better and brighter place
B．paralyzed people of today have the hope recovery
C．the report of the breakthrough will be published soon
D．researchers across the world will carry out the operation．

Answer 1

分析 本文通过一例成功的手术向我们介绍了一项新的医学发明，把鼻腔细胞移植到其它受损器官帮助修复，治愈瘫痪病人．

解答 22．A 细节理解题．根据文章第二段第一句话中的…who found that cells had the possibility to repair damage to nasal （鼻腔的） nerves，the only part of the nervous system that constantly re-grows可知鼻腔细胞神经能够修补受伤的部位，并且能再生长．因此答案选A．
23．D 细节理解题． 根据文章第三段Polish doctors injected （注射） the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue．The nasal cells appear to have caused the spinal nerves to repair themselves可知利用鼻腔细胞移植，可以帮助脊髓神经自我修复，使Darek Fidyka能够行走和开车，因此答案选D．
24．D 细节理解题．根据文章第四段第一句话Professor Raisman achieved this with rats in the late 1990's，but this is his greatest success．可知是通过小白鼠的实验才得到了启发，有了医学发现，因此答案选D．
25．B 推理判断题．根据文章最后一段What you've got to understand is that for three million paralyzed people in the world today，the world looks a totally brighter place than it did yesterday可知David Nicholls对这项发现充满希望，希望能治愈更多的瘫痪病人，现在的世界比昨天更光明．因此答案选B．
