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

D. whether the operation is worth performing
答案：
【語(yǔ)篇解讀】 本文是說(shuō)明文。文章主要介紹了人體頭顱移植手術(shù)的可能性。
1. B 解析：細(xì)節(jié)理解題。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，到目前為止，人體頭顱移植的關(guān)鍵在于脊髓的再結(jié)合，故選B項(xiàng)。
2. C 解析：詞義猜測(cè)題。由前面的Connecting a head to a body is impossible for human beings today可知，Anthony Warrens教授認(rèn)為這種想法太荒謬了，故選C項(xiàng)。
3. A 解析：推理判斷題。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，恒河猴頭顱移植手術(shù)的成功使得脊髓再結(jié)合成為可能，故選A項(xiàng)。
4. A 解析：段落大意題。文章倒數(shù)第二段主要介紹了手術(shù)所需的時(shí)間、費(fèi)用、進(jìn)行手術(shù)的條件及其好處等，故選A項(xiàng)。
