Recently, scientists are reported to have grown a living human “brain”. The team at Aston University in UK 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.”
1.UK scientists grow a living human “brain” in order to ______.
A. separate cells from a cancer tumor

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

D. will make people discover dementia
3.From the last paragraph, we can know that ______
A. the technique provided by HRT is not fully developed
B. the research program lacks financial support
C. animal tests are no longer allowed by law
D. a million people suffer from brain diseases
4.The text is meant to ______.

科目:高中英語 來源:2015-2016年湖北武漢華中師大第一附中高一下期中英語卷(解析版) 題型:閱讀理解
When people introduce themselves, I always hear them say “I’m just a housewife”. I don’t understand why their introduction is always filled with regret and self-pity. Is it really a crime to be a housewife? Is it really embarrassing (令人尷尬的) when you choose not to work outside and instead choose to work in your home? Is income the only mark of being proud of what you are doing and how you are spending your life?
How could you be “you are just a housewife” when the basic social unit of society depends on you and your service? Isn’t it surprising that even if your day starts before everyone and ends after everyone, you still don’t feel that you have accomplished(實(shí)現(xiàn))anything? A housewife works for the longest hour, shelling out every responsibility of the house, supporting your husband, child studies, caring for elders, managing finances, paying bills, grocery shopping, cooking according to individual taste, cleaning, entertaining family and friends, maintaining a pleasant environment at home, remembering things that others have forgotten, looking after each and every requirement of the family members, etc. A housewife could be anyone: daughter, wife, mother, teacher, financial advisor, fashion designer and consultant, nurse, gardener, driver, cook, and so on. Don’t think you are not being paid for it. You get the reward that no money can offer—the love and affection (摯愛) of your family, their trust in you, a happy home and your own satisfaction.
It is you who choose to be in this occupation, willingly or for any other reason. After a busy day, all wait to return to the comfortable home set by you. They know you will be there to absorb all their stress and tiredness and relax them. Would the life have been the same had you been working outside to earn some money? Would you along with your family have been able to buy all the content in life that you are enjoying now with that money?
Respect yourself for what you are. Introduce yourself to the world with the same dignity. The world understands the importance of your job; it’s time to make them accept it. Introduce yourself with pride and with twinkle in your eyes “I am a housewife”. Kick that “just” out.
1.What is the housewives’ feeling when they say “I’m just a housewife” in the author’s opinion?
A. Nervous. B. Comfortable.
C. Regretful. D. Satisfied.
2.According to the author, the true value of the housewives lies in the following EXCEPT _______.
A. the harmony of their family
B. family members’ trust in them
C. the stable income of their family
D. the love and affection of their family
3.What does the author advise housewives to do when they introduce themselves?
A. Take care not to make a mistake.
B. Pick up self-confidence and pride.
C. Try to make others understand their life.
D. Understand the importance of their jobs.
4.How does the passage mainly develop?
A. By following the order of time.
B. By offering some questions.
C. By making comparisons.
D. By giving examples.
