Question

【題目】Scientists in UK have grown a living human “brain”. The team at Aston University created tiny bunch of cells which act like a mini nervous system.

They believe it could help find a cure for worse mental conditions like Parkinson’s disease. Professor Michael Coleman is leading the research program. He explained，“We are aiming to be able to study the human brain at the most basic level, using an actual living human cell system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works.” The experiment involves changing cells from a cancer tumor(腫瘤) and making them behave like brain cells.

Although far from finished, researchers hope the false brain cells will give them a greater understanding of how real brains work. This, in turn, could significantly further research into conditions which affect the brain. Neil Hunt, chief leader of the research group, said，“It is still very early days, but in the future the research could lead to a useful tool for looking into dementia (癡呆)．”

The technique could also provide a way to carry on animal test and is being supported by the Humane Research Trust (HRT). The scientists predict that over the next ten years a million people will develop dementia. Professor Coleman believes their findings could change this. He said，“We hope our research will provide scientists with a new and highly relational human experimental model to help them understand the brain better and develop new drugs to control the related disease. However, the biggest challenge at present is that we are greatly short of fund, which will slow our research.”

試題分析：本文是一篇科普類說明文。主要介紹了英國科學(xué)家們正在進(jìn)行培養(yǎng)腦細(xì)胞的實(shí)驗(yàn)，希望通過這樣的實(shí)驗(yàn)?zāi)芨�好地理解人類大腦結(jié)構(gòu)，從而幫助人們治療一些腦部疾病。

【1】選C 細(xì)節(jié)理解題。根據(jù)第二段中的““We are aiming to be able to study the human brain at the most basic level, using an actual living human cell system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works.” .”可知，他們希望通過這樣的研究試驗(yàn)來理解人腦是如何工作的。故選C。

【2】選D 細(xì)節(jié)理解題。根據(jù)第三段最后一句中的“It is still very early days, but in the future the research could lead to a useful tool for looking into dementia (癡呆)．”可知，現(xiàn)在研究尚處于初期，但將來可能會(huì)成為研究癡呆疾病的有效手段。故選D。

【3】選D 細(xì)節(jié)理解題。根據(jù)最后一段最后一句However, the biggest challenge at present is that we are greatly short of fund, which will slow our research.”可知，現(xiàn)在研究最大的問題是缺少資金。故選D。

【4】選B 寫作意圖題。本文屬于科普類說明文，主要介紹了英國科學(xué)家們正在進(jìn)行培養(yǎng)腦細(xì)胞的實(shí)驗(yàn)，希望通過這樣的實(shí)驗(yàn)?zāi)芨�好地理解人類大腦結(jié)構(gòu)，從而幫助人們治療一些腦部疾病。故選B。
