Question

19．Brain Transplants
Research on the human brain has been attracting more and more scientists in recent years．（71）GIf we compare a human brain to a hard disc，what the scientists are doing is to make better use of the hard disc．
The idea that a human brain could be transplanted （移植） may come from Frankenstein．In 1999，an experiment turned a bear into a dolphin （海豚）．（72）FThey were made of the memory area in the dolphin's brain containing information about swimming．They had a series of useful information，which was saved into a button-sized chip （芯片）．Later the information was transplanted into the action memory area in the bear's brain．（73）CIt proved to be a highly successful experiment and a bear was turned into a dolphin．
Recently，another memory transplant was performed at the Motor Nerve Rescarch Instance of the University of California．The experiment bad an entire transplant of the memory area．（74）BThe transplant was performed from a dog named Cenius to a dog named idiot．Cenius could follow up to 100 gestures and orders made by its master．It was a real genius in memorizing．However，Idiot had no contact with people since its birth．It because an animal with nothing in its brain，without any memory．
（75）AWhen the two dogs woke up，Idiot had grasped all the abilities Cenius possessed； it was good at memorizing and sensible．It could follow every gesture and any command given by its master．But Cenius gave no response to its master，and did not recognize him at all．

A．The experiment was a complete success．
B．It included actions，moods，logic，words，images，etc．
C．Then it was released （釋放） by means of electric power．
D．Different images have different meanings in the memory area．
E．Using the most advanced technology，detailed images were produced．
F．Discoveries show that messages are carried by the central nervous system in the brain．
G．One of the latest topics is how to change the human brain or combine it with the computer．

Answer 1

分析 本文屬于說明文的閱讀范疇．主要介紹了科學家在大腦移植中所做出的努力，通過動物進行實驗，經(jīng)過努力最終取得了成功，并對人類大腦的移植提供了可靠的依據(jù)．

解答 GFCBA
71．G．考查上下文的理解能力．前面提到科學家對大腦的研究更加感興趣，后面說把大腦比作計算機硬盤，那么G項中描述的最近的一個話題就是如何把人類大腦和計算機聯(lián)系起來符合文章的內(nèi)容；故選G．
72．F．考查上下文的理解能力．本段提到了大腦移植，并以熊與海豚為例，那么接下來敘述的自然是研究發(fā)現(xiàn)的問題，故選FDiscoveries show that messages are carried by the central nervous system in the brain．信息主要是由大腦中的中樞神經(jīng)輸送的．
73．C．考查上下文的理解能力．這是敘述的實驗的步驟Later the information was transplanted into the action memory area in the bear's brain，C項中的then緊承上文進行敘述，故選C．
74．B．考查上下文的理解能力．開頭一句說明這是進行的另一項實驗，結(jié)合The experiment bad an entire transplant of the memory area可知，后面描述的是實驗包含的環(huán)節(jié)等，所以B項It included actions，moods，logic，words，images，etc．與此相吻合．
75．A．考查上下文的理解能力．通過后面的描述Idiot had grasped all the abilities Cenius possessed； it was good at memorizing and sensible．It could follow every gesture and any command given by its master．可知，實驗取得了成功；故選A．

點評 對于選句填空這種題型要搞明白上下文之間的邏輯關系，要根據(jù)對話者所說的語氣及語義關系來做出判斷；只要符合文章的結(jié)構(gòu)、通順合理即可．
