Question

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。In recent years, research on the human brain has been attracting more and more scientists. 【1】 If we compare a human brain to a hard disc(硬盘), what the scientists are doing is to make better use of the hard disc.Experiments have started on animals. In 1999, a transplant(移植) experiment was done at the Defense and Military Physiology Research Institute in the U.S. and turned a bear into a dolphin(海豚). 【2】They were made of the memory area in the dolphin’s brain containing information about swimming. They obtained 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. 【3】 It proved to be a highly successful experiment and a bear was turned into a dolphin.Not long ago, another memory transplant was performed at the Motor Nerve Research Institute of the University of California. The experiment had an entire transplant of the memory area. 【4】 The transplant was performed froma dog named “Genius” to a dog named “Idiot”. “Genius” could understand and 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 at all since its birth. It became an animal with nothing in its brain, without any memory.【5】When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” had; it was good at memorizing and sensible. It could follow every gesture and any command given by itsmaster. But “Genius” gave no response to its master, and in fact did not recognize him at all.

A. The experiment was a complete success.

B. Then it was released(释放) by means of electric power.

C. One of the latest research topics is how to change the human brain or combine it with the computer.

D. Different images have different meanings in the memory area.

E. It included actions, moods, logic, words, images, etc.

F. Discoveries show that messages are carried by the central nervous system in the brain.

G. Using the most advanced technology, detailed images were produced.

【解析】试题分析:本文讲述了科学家对人脑的研究，主要讲述了对人脑移植的研究和在动物身上的实验。

【1】C考查对上下文的理解和推理判断能力。根据If we compare a human brain to a hard disc(硬盘),如果我们把人脑比作硬盘，C选项One of the latest research topics is how to change the human brain or combine it with the computer.最新的一个研究是如何改变人脑或者把人脑和电脑连在一起，符合，故选C。

【2】G考查对上下文的理解和推理判断能力。根据They were made of the memory area in the dolphin’s brain containing information about swimming它们是由海豚脑中包含游泳信息的记忆区域形成的， G选项Using the most advanced technology, detailed images were produced.使用最先进的技术能产生细化的图像，符合，选择G.

【3】B考查对上下文的理解和推理判断能力。 根据Later the information was transplanted into the action memory area in the bear’s brain.信息被移入熊脑中的行动记忆区，B选项Then it was released(释放) by means of electric power.它通过电能被释放，符合，故选B。

【4】E考查对上下文的理解和推理判断能力。根据The experiment had an entire transplant of the memory area.实验对记忆区进行了整个的移植 ，E选项It included actions, moods, logic, words, images, etc.它包括了行动、情绪、逻辑、语言、图像等 ，符合，故选E。

【5】A考查对上下文的理解和推理判断能力。根据When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” had两只狗醒来时，愚蠢的那只掌握了聪明的那只的所有能力 ，A选项The experiment was a complete success.实验很成功符合 ，故选A.
