Scientists think it will be possible to record people's dreams and then interpret them, according to a new report.
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(影像) 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(神经元) 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 visualisation would be of limited help when it came to interpreting the "complex dream narrative".
In addition to get a detailed picture of individual neurons subjects had to have electrodes implanted(植入电极) 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(癫痫).
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.According to the passage, psychologists try to interpret people’s dreams______.
| A．by recording higher level brain activity |
| B．by comparing people’s memories of their dreams with an electronic visualization |
| C．by asking about people after their dreams |
| D．by linking certain neurons with specific objects or concept |

When 47-year-old volunteer Susan Boyle stepped onto the stage of Britain’s Got Talent and announced she was unemployed, had never been married and “never been kissed, actually”, few in the audience would have wondered why. This Ms Boyle, looking unfashionable, from a village in Scotland, shocked the three judges and the audience with the song I dreamed a dream from the musical Les Miserables on a show of Britain’s Got Talent, one of the hottest reality shows in Britain.
She couldn’t hide the awkwardness when walking to the center of the stage in a housedress, and everyone — including the judges — seemed laughing at her when she said she wanted to be as successful as Elaine Paige. As soon as she began singing, however, everyone in the auditorium fell silent, then rose within seconds to applaud her incredible voice as the celebrity judges sat open-mouthed, and remained standing to the end.
After her performance, one of the judges Piers Morgan said, “Without doubt that was the biggest surprise I’ve had in three years of this show. When you stood there everyone was laughing at you. No one is laughing now. That was amazing.” Actress Amanda Holden followed, “I’m so thrilled because I know that we everybody were against you. I honestly think that we were all being very cynical (愤世嫉俗的) and I think that’s the biggest wake up call ever.”
Susan obviously won over the hearts of millions around the world with sensation spreading across the Atlantic. Hollywood actors Ashton Kutcher and Demi Moore — who between them have nearly 1.5 million followers — speak highly of her. Kutcher posted a link to the video clip (片段). The Scottish talent made her live American debut via satellite connection on CBS’s The Early Show, doing an interview and singing live from her room. And she already accepted an invitation from talk show host Oprah Winfrey.

Shopping in the United States changes a lot．About ninety years ago most people shopped in small stores that were owned by one person or a family．Women went from the bakery to the butcher's to the grocer and on to the fruit and vegetable seller in order to get their food for the week．

Learning new words is learning new ideas: High school students can take control of
their learning by always looking up new words and finding out what they mean. They should keep a dictionary and a thesaurus close at hand.
Make clear lists: Students should make a list of everything that they need to get done. They should check off assignments（作业）once completed. They should include clear due dates.
Make a commitment: Active learners will resolve to keep up –to-date from the start. They will avoid procrastinating. They will complete most of their work as early as possible.
Independent work is best: Students will do all assignments independently—they will never copy! Students who copy are passive learners. Passive learners do not give their mind a chance to think on its own.
Organization is key: Students should keep an excellent folder and notebook. All problems should be clearly stated and solutions given. All tests and quizzes should be corrected and used as study guides for exams and finals.
All actions without solutions are dead: Active learners will always show their work needed to solve a problem. Active learners will never turn in a list of answers without giving an explanation or a solution.

According to the United States government, people are classified as homeless if they have no place to stay and no expectation of finding a place for the next thirty days．Although technically accurate, that is an impersonal assessment of an enormous and very human problem．
The homeless population represents all of us Americans．It includes men and women, the elderly, children, and infants．Its members are from all ethnic groups．What they have in common is poverty．
Currently in the U．S．, thirty-nine million people live in poverty．When money is really tight, paying the rent or buying food often becomes a choice．Government assistance in the form of food stamps does help but, as one homeless man explains, you can’t pay the rent with food stamps．
With no money for rent, the streets and homeless shelters become the alternative．
Although men constitute the largest group within the homeless population, homeless women with children are rapidly joining them．In fact, one quarter of the homeless people in the U．S．are teenagers and young children．
People may become homeless for numerous reasons．However, there are certain factors that many of these individuals have in common．They include a lack of adequate education and job skills．A majority of the teenagers and adults have not completed high school．
The abuse of alcohol and drugs is also a common factor．One third of the adult homeless population abuses alcohol．While one quarter of the same group uses drugs．
Some members of this population suffer mental health problems．Within the past several years many institutions for the mentally ill have been closed and their patients sent “home”．Unfortunately, a number of those people have no home to go to and they are unable to adequately look after themselves．
Job loss in today’s economy has also become a real factor in the loss of people’s homes．The breakup of families through abandonment and divorce are also contributing factors, particularly when there are children involved．The parent who is left to care for the kids with inadequate income may be forced to depend on the homeless shelters to put a roof over their heads．The writer thinks that the U．S．government’s definition for the homeless reveals ________．
| A．an insincere attitude toward the homeless |
| B．an unbearable attitude toward the homeless |
| C．an uncivilized attitude toward the homeless |
| D．an unsympathetic attitude toward the homeless |

During a state of deep relaxation, several physiological changes take place in the body: the body’s oxygen consumption is reduced; the heart beat decreases; muscle tension and sweating ease, and there is decreased sympathetic （交感的） nervous system activity．This restful state not only allows the body to repair and restore itself, but it has a calming effect on the consciousness．
How to achieve this state of relaxation, however, is a matter of opinion, and in some medical circles, a matter of controversy．A recent report by Dr．David Holmes of the University of Kansas in the journal “American psychologist” said that simply sitting in an armchair has just as many beneficial characteristics for the body as meditation （冥想） does．Researchers of other relaxation techniques disagree．These experts believe that more structured techniques, such as meditation, lead to a condition of deep relaxation．
The debate goes on, but one thing appears to be clear: the relaxation response can be reached by a number of methods, and the methods themselves are not as important as getting there．One day, one method may work best; on another day, an alternative method may be more appropriate．Once you are aware of all the methods, you can find the one that works best on you．
Some of the relaxation techniques are meditation, auto analysis and progressive muscle relaxation response．More than just sitting quietly in a chair, they have the added benefit of structure and discipline, and for these reasons appear to be more effective for most individuals．According to the passage, which of the following statements is NOT true when a person is in a state of deep relaxation?
| A．The body takes in less oxygen． |
| B．The heart beats less frequently． |
| C．Muscles become tense and the body sweats easily． |
| D．The consciousness becomes more or less calmed． |
People seem to agree that ____．
| A．sitting in an armchair benefits a person as meditation does |
| B．structured relaxation techniques are more beneficial for a person |
| C．to achieve a state of deep relaxation is possible through various means |
| D．what people are all struggling for is a state of deep relaxation |
In the third paragraph, the phrase “getting there” means _____．
| A．arriving at one’s destination |
| B．getting what one wants most |
| C．finding out a suitable relaxation technique |
| D．reaching a state of deep relaxation |
The author’s attitude toward relaxation discussed in the passage is best described as ______．
| A．sceptical | B．objective | C．optimistic | D．critical |
