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

Carlos had been in New York for five months now, and he detested it. He would never forget the day when the plane landed. His parents had big smiles on their faces as they discussed the wonderful new life they would have in this great city. His older sister and brother looked in wonder and excitement at the buildings. Uncle Miguel and Aunt Esperanza thought of the good jobs they would get. Grandmother and Grandfather told him what a lucky boy he was to come to this wonderful city. But Carlos was lonely. The city looked big, cold, and dirty to him.
They lived in an apartment in Manhattan. There were stores and cinemas close to their home. But Carlos didn’t want these things. He loved his home in the country in Puerto Rico; he loved the green fields, the hot sun, and the lovely beaches.
He didn’t want to go to school because it made him think of his friends at home. And he didn’t want to learn a new language that could never describe the world as beautifully as his own.
He began to go down to the dock(码头), because this made him feel closer to Puerto Rico. He sat down and watched the ships. He would often find a man also sitting there looking at the sea. The man was Eric-a taxi driver who came there to escape from the noisy traffic.
Eric noticed the young boy and felt his sadness. One day he said, “Yes, it’s hard to leave your homeland. I remember when I left Norway 15 years ago. I know it’s hard to start a new life in a new country, but let’s face it. I did it and you can do it, too.”

Many people love keeping the pets (dogs, cats, horses, etc) and have them as their good friends. In Canada, people usually take their pets to animal hospitals to give them injections (注射) so that they won't carry diseases before they keep them in their houses. They have special animal food stores, though they can get animal food in almost every kind of stores. Some people spend around two hundred Canadian dollars a month on animal food.
When you visit people's houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals.

I had a lot of teachers that I loved. However, the teacher that I remember most was Mrs. Green from Marianna, Florida. She was my 5th grade teacher. Since I was a new student, not only in her class, but at the school, she made my time there much more pleasant. I immediately began to like her. She was really funny and I knew that she liked me. She made learning fun. I remember one day for Christmas holidays, she taught us how to make ornaments(装饰物) from eggs. My parents still have some of the ornaments I made.
She made me leader for many group projects and that made me feel special. I think that would make any child feel special, especially when a child is in a new place with no friends. She made me want to be like that. Not to pick a “favorite” student, but to make every student feel that they are special. That year, I received the Presidential Academic Award(美国总统学术奖) . I was really proud and so were my parents.
Looking back at it, I think the reason why I did so well was that I felt important. Students do better when they feel like they are important or loved. Mrs. Green always gets to know her students and forms personal relationships with them, which I will try to do some day. I just hope that there will be a student who finds me to be their favorite teacher as I found her to be mine. The author’s life in the new school was very _______.
| A．hard | B．happy | C．common | D．boring |
What can we learn from the second paragraph?
| A．The author was Mrs. Green’s favorite student. |
| B．The author was the pride of her parents. |
| C．The author was once received by the President. |
| D．The author always felt lonely in Mrs. Green’s class. |
What will the author probably do in the future?
| A．become a teacher | B．become an artist |
| C．become a leader | D．become the President |
How does the author feel about Mrs. Green’s help?
| A．Sorry | B．Afraid |
| C．Hopeful | D．Thankful |
