A
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.”
1. 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.
2. The underlined word “bizarre” in Paragraph 2 probably means ________.
A. exciting B. clear
C. strange D. unpleasant
3. Robert White's experiment on rhesus monkeys shows ________.
A. the possibility of reconnecting the spinal cord
B. the difference between animals and humans
C. a breakthrough in human head transplant
D. some unsolved technical difficulties
4. The last but one paragraph mainly talks about ________.
A. the operation of human head transplant
B. the development of transplant technology

D. whether the operation is worth performing
答案:
【语篇解读】 本文是说明文。文章主要介绍了人体头颅移植手术的可能性。
1. B 解析:细节理解题。由第一段中的Up until now there has been no way to successfully reconnect the spinal cord及第三段第二句可知,到目前为止,人体头颅移植的关键在于脊髓的再结合,故选B项。
2. C 解析:词义猜测题。由前面的Connecting a head to a body is impossible for human beings today可知,Anthony Warrens教授认为这种想法太荒谬了,故选C项。
3. A 解析:推理判断题。由第三段中的In 1970 Robert White successfully transplanted the head of a rhesus monkey onto the body of a second rhesus可知,恒河猴头颅移植手术的成功使得脊髓再结合成为可能,故选A项。
4. A 解析:段落大意题。文章倒数第二段主要介绍了手术所需的时间、费用、进行手术的条件及其好处等,故选A项。
