Question

Scientists in theUKhave grown a living human "brain". The team at Aston University created a 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 programme. He explained, "We are aiming to be able to study the human brain at the most basic level, using an actual liv?ing human cell system. Cells have to be alive and oper?ating efficiently to enable us to really understand how the brain works. The experiment involves changing cells from a cancer tumour (肿瘤)and making them be?have 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 signifi?cantly 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 re?search could lead to a useful tool for looking into dementia (痴呆）."

The technique could also provide a way to carry on animal tests and is being supported by the Humane Re?search 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 scien?tists with a new and highly relational human experimen?tal model to help them understand the brain better and develop new drugs to control the related disease. How?ever, the biggest challenge at present is that we are greatly short of fund, which will slow our research.，，

Answer 1

【文章大意】本文介绍了英国科学家对人类大脑进行的一项研究，希望能够了解人类大脑的工作原理，为一些精神疾病找到治疗方法。

C推理判断题。根据文章第二段中的"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 op?erating efficiently to enable us to really understand how the brain works."可知，这个研究的目的在于研究人类的大脑是如何工作的。故C项正确。

D推理判断题。根据第三段最后的"Neil Hunt, chiefleaderof the research group, said, 'It is still very early days, but in the fu?ture the research could lead to a useful tool for looking into de?mentia (痴呆）."可知这样的研究会导向一种有用的工具来研究痴呆这样的疾病。故D项是正确的。

D 细节理解题。根据文章最后一句"However, the big?gest challenge at present is that we are greatly short of fund, which will slow our research.'"可知，这个研究目前最大的挑战就是缺少资金。故D项正确。

B 目的意图题。根据文章第一段"Scientists in the UK have grown a living human'brain，. The team at Aston University created a tiny bunch of cells which act like a mini nervous systern."可知，本文介绍了英国科学家对人类的大脑进行研究的一项计划。故B项正确。
