Question

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 (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."

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. separate cells from a cancer tumour

2. According to Neil Hunt, research into brain cells ______.

A. will get finished as early as possibleB. will make people discover dementia

C. will affect the brain growth in many ways

D. will help to treat some diseases in nerve system

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

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

 

Answer 1

1.C

2.D

3.D

4.B

【解析】本文介紹了英國科學家對人類大腦進行的一項研究，希望能夠了解人類大腦的工作原理，為了一些精神疾病找到解決方法。

1.C

【試題解析】推理題。根據(jù)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.可知這個研究的目的在于研究人類的大腦是如何工作的。故C正確。

2.2】D

【試題解析】推理題。根據(jù)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 (癡呆)."可知這樣的研究會讓我們發(fā)現(xiàn)一種有用的工具來研究癡呆這樣的疾病。說明D項的說法是正確的。

3.3】D

【試題解析】細節(jié)題。根據(jù)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可知這個研究的最大的問題就是缺少資金。故D正確。

4.4】B

【試題解析】目的意圖題。根據(jù)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可知本文介紹了英國科學家進行的一項對人類的大腦的研究計劃。故B正確。

【長難句解析】

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

【翻譯】然呢榮，現(xiàn)在最大的挑戰(zhàn)是我們的資金短缺，這會減緩我們的研究。

【分析】本句中含有一個that引導的表語從句that we are greatly short of fund, which will slow our research，that在句中不充當任何成分，只是一個引導詞而已。另外句中還有一個非限制性定語從句which will slow our research，which指代前面缺少資金這件事情，在句中做主語。
