Question

【題目】閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。

Research on the human brain has been attracting the attention of more and more scientists in recent years. 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 (移植) a chip into human brain. This innovation (創(chuàng)新) may make everyone’s dream come true. If we compare a human brain to a hard disc, what the scientists do is to enlarge the capacity (容量) of the hard disc. There are some difficulties in such transplant experiments, but scientists 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 studies were made of the swimming action memory area in Ted’s brain by the scientists. They got a lot of useful information. The 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 memory transplant was performed at the Motor Nerve Research Institute of the University of California. 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. “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 all the abilities “Genius” possessed. It could follow every gesture and order given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.

【1】We can learn from the passage that _____.

A. the two experiments are about memory transplants

B. the scientists exchanged the dolphin’s and the bear’s brains

C. there is no possibility of changing the human brain

D. “Idiot” got only some abilities “Genius” possessed after the experiment

【2】The scientists did the two experiments to _____.

A. see if animals can be taught some special skills

B. see if animals can share some common knowledge

C. learn if it’s safe to do such transplant experiments

D. make preparative research on changing the human brain

【3】The underlined sentence “The operation was a complete success” in the last paragraph means that _____.

A. the dogs exchanged their memories

B. the dogs could live as before

C. the dogs were as clever as human beings

D. the dogs were safe

【4】It could be inferred from the passage that in the future _____.

A. human beings will be healthier

B. animals will be more tender

C. human beings may get knowledge more quickly

D. animals will cause more damage to the environment

【3】A

【4】C

【解析】

試題分析：本文屬于科普類閱讀，主要介紹了人類對(duì)記憶移植進(jìn)行的相關(guān)研究，介紹了在動(dòng)物身上進(jìn)行的兩次成功的移植試驗(yàn)。

【1】A 細(xì)節(jié)理解題。根據(jù)第二段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.和第四段前兩句Recently, .......The transplant was performed from a dog named “Genius” to a dog named “Idiot”.可知文章中介紹了兩個(gè)與記憶移植有關(guān)的兩個(gè)實(shí)驗(yàn)。光顧A正確。

【2】D 推理判斷題。根據(jù)第一段最后一句There are some difficulties in such transplant experiments, but scientists never give up.和第二段第一句 Experiments were started on animals.可知在記憶移植方面有很多的困難，但是科學(xué)家并沒(méi)有放棄，他們首先在動(dòng)物身上進(jìn)行了有關(guān)的實(shí)驗(yàn)。目的是為人類的記憶移植進(jìn)行準(zhǔn)備。故D項(xiàng)正確。

【3】A 句意理解題。根據(jù)第四段第二句The transplant was performed from a dog named “Genius” to a dog named “Idiot”.可知這項(xiàng)研究是在兩條狗身上進(jìn)行的。本句The operation was a complete success. 指這個(gè)研究很成功，也就是說(shuō)兩條狗成功地交換了記憶。故A項(xiàng)正確。

【4】C 推理判斷題。根據(jù)文章第一段可知我們使用記憶移植這一方法，可以把其他的記憶通過(guò)芯片植入我們的頭腦中。這樣我們可以迅速第獲得更多的知識(shí)。故C項(xiàng)正確。
