They claim to have developed a system which allows them to record higher level brain activity. Dr Moran Cerf told the journal Nature: "We would like to read people's dreams." Previously the only way to access people's dreams is for psychologists to ask about them after the event and try to interpret them. Dr Cerf hopes to eventually compare people's memories of their dreams with an electronic visualization of their brain activity. He told the BBC: "There's no clear answer as to why humans dream. And one of the questions we would like to answer is when do we actually create this dream?" The scientist believes his latest research shows that certain neurons or individual brain cells are linked with specific objects or concepts . He found that a particular neuron lit up when a volunteer thought about Marilyn Monroe. If a database was built up identifying various neurons with concepts, objects and people it would allow them to "read the subject's minds", according to Dr Cerf. However, Dr Roderick Oner, a clinical psychologist and dream expert, said that this kind of visualization would be of limited help when it came to interpreting the "complex dream narrative ". In addition to getting a detailed picture of individual neurons subjects had to have electrodes implanted deep in the brain using surgery. The Nature researchers used data from patients who had electrodes implanted to monitor and treat them for brain seizures . However, Dr Cerf said he hoped that it would be possible at a later stage to monitor people without invasive surgery .He said it would be "wonderful" to be able to read the minds of coma patients who are unable to communicate. Question: What's the main idea of the whole passage? Options: A: People can use many ways to interpret dreams. B: Scientists have different opinions about dreams. C: People's dreams will be recorded in the future. D: We have developed a system to record higher level brain activities.

One day one of his friends lost his wallet and asked Mark Twain to pay his train ticket for him. "But I don't have enough money to pay both your ticket and mine," Mark Twain said. The friend didn't know what to do. "We can do this," said Mark Twain." We can get on the train and when the conductor came to check the tickets , you can hide under my seat." Later, however, when the conductor came to check the tickets, Mark Twain gave him two tickets --- one for himself and one for his friend . Then he explained in aloud voice," My friend is a strange man. When he travels on a train, he does not like to sit on the seat." Of course everyone in the train looked at the poor friend under the seat and laughed at him loudly. Question: Why did the friend ask Mark Twain to pay his train ticket for him? Options: A: Because Mark Twain was very rich. B: Because the friend lost his money. C: Because Mark Twain was always ready to help others. D: Because the friend wanted to save his money.

Q: Read the article and select the best answer. Article: A good teacher is many things to many people. In my own experience, the people I respect the most and think about the most are the teachers who demanded the most discipline from their students. I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very vividly a sign over her classroom door. It was a simple sign that said, "Laboratory--in this room the first five letters of the word was emphasized , not the last seven." In other words, I guess, labor for her was more important than oratory, which means making speeches. She prepared her work very carefully and demanded us to do the same. We got lots of homework from her. Once she had broken her arm, and everybody in the class thought that maybe the homework load would be reduced, but it continued just the same. She checked our work by stamping her name at the bottom of the papers to show that she had read them. I think sometimes teachers who demand the most are liked the least. But as time goes by, this discipline really seems to benefit the students. Question: What's the writer's opinion of discipline? Options: A: It makes the students dislike their teachers. B: It does good to the students in the long run. C: It's too much for young children. D: It does more harm than good to the students.
A: B

Question: Read the article and select the best answer. Article: Whatever our differences as human beings are we all think we're more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic structure with the simple worm. But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome . To help them do this, they turned to the worm. The nematode worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better. What the worm told Sir John and his colleagues was that each of the cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up. Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death. Question: Sir John Sulston got a Nobel Prize for Medicine because he has_. Options: A: found that human beings are similar to the worm B: got the fact we share 40 per cent of our genetic structure with the simple worm C: found the computer which controls each of the cells in the human body D: proved that cell death is programmed

Researchers have developed a book with specially treated pages that can turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world. About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria. The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles of silver. The pages can be used as filters to remove harmful microorganisms that can pollute drinking water. The filter kills the organisms that pass through it. Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be cleaned. Ms. Dankovich, the inventor, says each page can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages. "The idea of classic texts--that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through _ " she says. Teri Dankovich and another researcher tested the drinkable book in Bangladesh, Ghana and South Africa. The tests proved to be successful. Water for Life, a non-governmental organization, has provided financial support for the project. Question: In which country did not the researchers test the drinkable book? Options: A: Bangladesh. B: Ghana C: South Africa. D: America.
