      题目内容:

      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 tumour (肿瘤)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 (痴呆)."

      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."

      小题1:UK scientists grow a living human "brain" in order to ______.

      A.study the structure of human brain

      B.make use of living human cell system

      C.discover how human brain really works

      D.will help to treat some diseases in nerve system小题3: From the last paragraph,we can know that ______

      A.the technique provided by HRT is immature

      B.animal tests are no longer allowed by law

      C.a million people suffer from brain diseases

      D.the research program lacks financial support小题4: The text is intended to ______.

      A.tell us about a breakthrough in medical research

      B.introduce a research program in human's brain

      C.introduce the progress of drugs for dementia

      D.tell us about health problem in nerve system

      最佳答案:

      小题1:C

      小题2:D

      小题3:D

      小题4:B

      答案解析:

      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,为了一些精神疾病找到解决方法。

      小题1:C

      【试题解析】推理题。根据文章第二段2,3行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.可知这个研究的目的在于研究人类的大脑是如何工作的。故C正确。

      小题2:D

      【试题解析】推理题。根据第三段最后2行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 (痴呆)."可知这样的研究会让我们发现一种有用的工具来研究痴呆这样的疾病。说明D项的说法是正确的。

      小题3:D

      【试题解析】细节题。根据文章最后一句However, the biggest challenge at present is that we are greatly short of fund, which will slow our research可知这个研究的最大的问题就是缺少资金。故D正确。

      小题4:B

      【试题解析】目的意图题。根据文章第一段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可知本文介绍了英国科学家进行的一项对人类的大脑的研究计划。故B正确。

      【长难句解析】

      However, the biggest challenge at present is that we are greatly short of fund, which will slow our research."

      【翻译】然呢荣,现在最大的挑战是我们的资金短缺,这会减缓我们的研究。

      【分析】本句中含有一个that引导的表语从句that we are greatly short of fund, which will slow our research,that在句中不充当任何成分,只是一个引导词而已。另外句中还有一个非限制性定语从句which will slow our research,which指代前面缺少资金这件事情,在句中做主语。

      考点核心:
