Research on the human brain has been attracting more and more scientists in recent years, just like the booming 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 transplant a chip into a human brain. This idea may make everyone’s dream come true. If we compare a human brain to a hard disc（硬盤）, what the scientists are doing is to enlarge the capacity of the hard disc. For the time being, there are some difficulties in such transplant experiments, but scientists never give up.

Experiments have 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 available, deep and detailed images were made of the memory area in Ted’s brain containing information about swimming by the scientists. They obtained a series of useful information, the signals transferred by the nervous system. Such information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin’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 Nerve 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 making a transfer 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 and sensible. It could follow every gesture and any command given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.

57. The purpose of the experiment is _____.

A. to combine the computer and the human brain    

B. to enlarge the capacity of human brain

C. to make some stupid dog turn clever          D. to make bear swim

58. Which of the following statements is TRUE?

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

B. The first 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

59. What does the underlined word “success” refer to?

A. The two dogs woke up.

B. They were both good at memorizing.

C. The Idiot grasped all the abilities of Genius.

D. The Genius grasped all the abilities of Idiot.

60. 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 related useful information

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

D. it is really good for animals to have been involved in the transplant experiment
