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 ______.

English is a very interesting language. It has borrowed words from many other languages. Immigrants(移民) coming into the United States have contributed many words to the language, which have kept their original pronunciation. “Coolie” and “kowtow” were taken from the Chinese language, “kamikaze from the Japanese, “shampoo” from India, “blitz” from German, “amigo” and “Los Angeles” from Spanish and so on.
Many students have studied English for years, some as many as eight. However, some students still have difficulty in speaking fluent English. Some know many words but are unable to discern them when native speakers use them. In our Oral English classes we will focus on speaking and listening to native English speakers. For this reason, because we are trying to train your ears to hear English and your mouths to speak intelligible (易理解的) English, we will have a rule that ONLY ENGLISH will be spoken in our English classes. Anyone speaking Chinese in class will be required to pay a fine in order to encourage the speaking and understanding of English. If teachers enter a classroom and discover that anyone is speaking Chinese, they will require everyone in the room to pay the fine. It is everyone’s job to enforce the English-Only rule. It is for your benefit. It is because we want to accustom (使习惯于) your ears to hearing English.
Other subjects may be learned solely from books but the only way to learn a foreign language is to SPEAK IT! Students are often nervous about speaking in class at first but we hope to make the classes fun, so you will forget your nervousness and learn to speak out. Enjoy your classes.The first paragraph is mainly about________.
| A．the difficulty of learning English. | B．how interesting and various English is |
| C．different words in different languages | D．the immigrants’ contributions to America |
The underlined word “discern” in Para 2 can be replaced by___________.

A dog can’t speak words, but it can “talk”. It has feelings just as you do. At times it may feel angry or afraid. Watch a dog closely. You can see what it is trying to tell you. When you are afraid, you may look down shyly. A fearful dog looks away from you. It may run away too. When you are angry with people, you stare at them and press your lips together. An angry dog also stares. Sometimes the hair along its back stands up.
Do you feel guilty when you have done something you shouldn’t? Dogs can feel guilty, too. At times when I come home, my dog gives me a guilty look. Then I know he’s done something wrong.
Dogs need love and attention. Some dogs are very unhappy when they are left alone for a long time. Some dogs even snap(撕咬) if they don’t get enough attention.
You may have a dog or you may know a dog. Treat it well if you want to have fun with it. Play with it. Take it on walks. Don’t order it round too much. Try not to punish it one time and not the next for doing the same thing. Always remember, a dog has needs and feelings just as you do.

An old woman went suddenly blind. She promised a doctor a lot of money if he could make her see again. “If you fail”, she said, “ you will get nothing,” The doctor agreed with her.The doctor soon discovered what was wrong with her, but he decided not to cure her right away. Instead, each time he visited, he secretly took some of her things. When he had taken everything that he wanted, he cured her blindness and sent her a large bill. Now when the old woman could see again she noticed that all her things had gone and she refused to pay the bill. So the doctor took her before a judge.

Ideas about polite behavior are different from one culture to another. Some societies, such as America and Australia, for example, are mobile and very open. People here change jobs and move houses quite often. As a result, they have a lot of relationships that often last only a short time, and they need to get to know people quickly. So it’s normal to have friendly conversations with people that they have just met, and you can talk about things that other cultures would regard as personal.
On the other hand, there are more crowded and less mobile societies where long–term relationships are more important. A Malaysian or Mexican business person, for example, will want to get to know you very well before he or she feels happy to start business. But when you do get to know each other, the relationship becomes much deeper than it would in a mobile society.
To Americans, both Europeans and Asians seem cool and formal at first. On the other hand, as a passenger from a less mobile society puts it, it’s no fun spending several hours next to a stranger who wants to tell you all about his or her life and asks you all sorts of questions that you don’t want to answer.
Cross-cultural differences aren’t just a problem for travelers, but also for the flights that carry them. All flights want to provide the best service, but ideas about good service are different from place to place. This can be seen most clearly in the way that problems are dealt with.
Some societies have “universalist” cultures. These societies strongly respect rules, and they treat every person and situation in basically the same way. “Particularist” societies, on the other hand, also have rules, but they are less important than the society’s unwritten ideas about what is right or wrong for a particular situation or a particular person. So the normal rules are changed to fit the needs of the situation or the importance of the person.
This difference can cause problems. A traveler from a particularist society, India, is checking in for a flight in Germany, a country which has a universalist culture. The Indian traveler has too much luggage, but he explains that he has been away from home for a long time and the suitcases are full of presents for his family. He expects that the check–in official will understand his problem and will change the rules for him. The check–in official explains that if he was allowed to have too much luggage, it wouldn’t be fair to the other passengers. But the traveler thinks this is unfair, because the other passengers don’t have his problem.Often moving from one place to another makes people like Americans and Australians ______.
| A．like traveling better |
| B．easy to communicate with |
| C．difficult to make real friends |
| D．have a long–term relationship with their neighbors |

| B．People obey the society’s rules completely. |
| C．No one obeys the society’s rules though they have. |
| D．The society’s rules can be changed with different persons or situations. |
The writer of the passage thinks that the Indian and the German have different ideas about rules because of different ______.
| A．interests | B．habits and customs | C．cultures | D．ways of life |
If you think English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the earlier people learn a second language, the greater the effect is.
A team led by Dr. Andrea Mechelli, from University College London(UCL), took a group of Britons who only spoke English. They were compared with a group of “early bilinguals(通两种语言的人)”, who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference was.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills.
“Having two languages gives you two windows on the world and makes the brain more flexible,” he said, “You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading, writing and comprehension were all tested. The results showed that the earlier they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists. What does the underlined part “grey matter” (in Paragraph 2) refer to?
| A．Grey hair. | B．Material of the brain. |
| C．Intelligence. | D．Difficult situations. |
The experience of learning a second language can ________.
| A．change one’s brain completely | B．improve one’s maths skills |
| C．make one smarter than others | D．increase the ability to learn |
We can learn from the passage that ________.
| A．the researchers from UCL did another study in Italy |
| B．a similar study was done on native Italian speakers who learn English as a second language |
| C．the research done on the Italians showed a totally different result |
| D．it will be easier for one to travel around the world by learning a second language |
What’s the main idea of the passage?
| A．Learning a second language can help improve your brain power. |
| B．You should learn a second language that is not your native language. |
| C．If you want to learn a second language, you should do it at a certain age. |
| D．The research done by the researchers from UCL is very successful. |
