Question

Research on the human brain has been attracting more and more scientists in recent years., just like the booming(昌盛的)hi-tech industry. One of the latest research topics is how to change the human brain or combine the Computer and the human brain, i. e, to transport a chip into human brain. This innovation(改革) may take everyone’s dream come true .If we compare a human brain to a hard disc, what the scientists are doing is to enlarge the applicable capacity of the hard disc. For the time being, there are some difficulties in such transport experiments, but scientist never give up.

Experiments were started on animals .In 1996 , a transplant experiment performed at the Defense and Military Physiology Research institute in the U.S. turned a bear into a dolphin.

The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology, deep and detailed were made of the swimming action memory area in Ted’s brain by the scientists. They obtained a series of useful information, the signals transferred by the nerve system. Such information was saved into a button—sized chip, which was then transplanted into the action memory area in Tallinn’s brain. The information saved on the chip was released by means of electric power.

Recently, another comprehensive memory transplant was performed at the Motor Never Research Institute of the University of California. The comprehensive memory transplanted in the experiment included actions, moods, logic ,words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.

The transplant was performed from a 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 .”Idiot” was the younger brother of “Genius”. It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.

The operation was a complete success. When the two dogs woke up .”Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing , sensible. It could follow every gesture and other given but its master. But :genius” gave no response to its master, and in fact did not recognize him at all.

1.The purpose of the experiment is _______.

A. to combine the computer and the human brain

B. to make bear swim

C. to make some stupid dog turn clever

D. to enlarge the applicable capacity of human brain

2.Which of the following statement is true ?

A .The scientists transferred a button—sized chip with useful information in Tallin’s brain.

B. The comprehensive memory transplant was performed at the Motor Nerve Research University.

C. The second experiment wasn’t an entire transplant of the memory area.

D. The idiot was an animal with memory before brain experiment.

3.What dose the underlined word “success” refer to ?

A. The two dogs woke up.

B. They were both good at at memorizing .

C. The idiot grasped all the abilities .

D. The Genius grasped all the abilities.

4.According to the text, we can infer ______.

A.    a person can know more after the experiment

B. a bear can swim after being transferred a chip with relevant useful information

C. a dog can become clever after entire transplant of the memory area

D. it is really good for animals to have transplant experiment

 

Answer 1

1. 答案D。該題屬于主旨大意題。第一段說科學家并沒有放棄移植實驗，第二段第一句又說實驗是從動物開始的，由此可見，實驗的目的最終還是針對人。

2. 答案A。該題屬于事實細節(jié)題。選項B中地點應是Motor Never Research Institute of University of California ；文中明確指出這次實驗是一次記憶區(qū)域的完全移植，故選項C錯誤；選項中的“idiot”指的是狗“Genius”。

3. 答案C。該題屬于詞句釋義題。由最后臆斷可知，第二個實驗的目的是讓小狗 “idiot”被植入芯片或變聰明。故正確答案是C。

4. 答案B。該題屬于判斷推理題。由文中的實驗得知，當有用的信息芯片被完全移植到某一動物腦中時，可使動物具備與相關信息有用的功能。因此，B為正確答案。
