     Dr. Glenn Tisman, a cancer specialist, knew his young neighbor, Ray Bateman, had an unusual mind.

But he had no idea at the time that 12-year-old Ray had the ability to become his partner in cancer

research.

     Ray' s parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner (吸

尘器). When he was ten, he speedily constructed the family color television from a kit.Later, he

succeeded in assembling (组装) a complex stereo system after two experts had failed to do the job.

     When Ray was ten, he convinced his parents to buy him a computer.In a short time, Ray was able to

do amazing things with the computer.Ray shared his enthusiasm for computers with Dr. Tisman, who

used a computer for his research. The two discussed computers and medicine frequently.Amazingly, Ray

understood the biology and chemistry related to Dr. Tisman's medical research without any previous

instruction.

     Ray then worked with Dr. Tisman after school.He helped conduct research with the equipment and

kept it in working order.The purpose of the research was to test the effectiveness of mixing an old cancer

drug with certain vitamins.Ray analyzed patient test results by computer, while Dr. Tisman handled all

patient contact.Together, they came up with solid research that helped advance cancer treatment.

     In 1988, 14-year-old Ray went with Dr. Tisman to a meeting of the American Federation for Clinical

Research (AFCR) , where Ray presented their initial research findings.Using terminology (术语) beyond

the grasp of most kids of his age, Ray told the scientists how the new drug mixture caused fewer and

milder side effects for cancer patients.

     A year later, Ray returned to the meeting to update the findings of his and Dr. Tisman' s research. By

then, he had become well-known for his devotion to finding cures for sick patients.Stories about him

appeared in hundreds of newspapers around the world.He appeared on television newscasts and talk

shows.

     Ray continued to spend most free hours working with Dr. Tisman.The two began studying the effects

of vitamins on babies inside the womb.However, Ray' s main interest remained cancer treatment, and he

continues his research today.

某大医院一位眼科博士，因急于为两位病人进行角膜移植，而又一时找不到现成的供体角膜，所以在太平间"盗取"了一病死者的尸体角膜用于移植，获得成功。此事后被死者家属发现，以未经本人生前及死者家属知情同意，严重损害了死者及其家属的权益为由，将该医生告上了法庭。经调查得知：接受眼角膜移植手术的两位病人与该医师无特殊关系；死者生前与该医师无利害冲突；该医师也未由此谋取分文私利，只是不了解有关要求。

该医师的行为出现了动机与目的、手段与效果严重背离的问题，其主观上的根本原因在于（）。

A.对患者知情同意权的无知

B.对医学创新的期望值很高

C.想以此改变人们的陈旧观念

D.想为科室创收作贡献

E.以上都不对
