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."

When I asked my daughter which item she would keep: the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said "the phone". Personally, I could do without the phone entirely, which makes me unusual. Because the telephone is changing our lives more than any other piece of technology.

Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been at school with all day. If the phone did not exist, would she have anything to talk about?

Point 2 The mobile phone means that we are never alone. !' The mobile saved my life, "says Crystal Johnstone. She had

an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance(救護(hù)車) to her rescue.

Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are, where they are going, and how their last meeting went.

Point 4 The telephone separates us. Antonella Bramante in Rome says, "We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near--but we didn't meet for the first two weeks!"

Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously (同時地) on chat lines (at least my daughter does. I wouldn't know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they're space-walking. And, with the phone line hooked up to the computer, we can access(進(jìn)入) the Internet, the biggest library on Earth.

1.How do you understand" Point 1—The telephone creates the need to communicate,... "？

A. People don't communicate without telephone.

B. People communicate because of the creating of the telephone.

C. People communicate more since telephone has been created.

D. People communicate more because of more traffic.

2.Which of the following best shows people's attitude towards mobile phones?

A. Mobile phones help people deal with the emergency.

B. Mobile phones bring convenience as well little secret to people.

C. Mobile phones are so important and should be encouraged.

D. Mobile phones are part of people's life.

3.Which points do you think support the idea that phones improve people's life?

a. Point 1. b. Point 2. c. Point 3. d. Point 4. e. Point 5.

A. c, d B. a, e C. a, c D. b, e

4.It is possible to talk to several complete strangers simultaneously through .

A. the TV screen B. a fax machine

C. the phone line hooked up to the computer D. a microphone

5.The best heading for the passage is .

A. The power of Phones B. Kinds of Phones

C. How to Use Phones D. Advantage of Phones
