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.

1.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

2.What’s the best title for this passage?

A. Scientists plan to record people’s dreams

B. Psychologists try to ask people about their dreams

C. Dream experts want to interpret the complex dream narrative

D. The Nature researchers intend to treat patients for brain seizures

3.According to Dr Cerf’s research, when a patient thinks about a famous film star, ______.

A. various neurons will identify the star as famous

B. a particular neuron will become bright with excitement

C. the star will appear in his brain

D. the star’s face will light up

4.The underlined word “coma” in the last paragraph most probably means______.

A. the lost of the ability to hear

B. being unable to control one’s movements

C. the state of being unconscious (无意识的)

D. being unable to move

Most people want to be successful, but never stop to think what it will really take to get there in their chosen field. If it means going back to college for 2 years of night school, could you do it ? If it means reading a book a week for about 6 months in order to really master a new skill ? If you aren’t prepared to do any of those things because they are outside of your comfort zone, then you can forget being succesful. I guarantee you will never reach your goals in life, unless your goals are to be ordinary.

The biggest killer by far is the dreaded “ comfort zone ” where most people live in their entire life. And the funny thing is that people just can’t wrap their heads around the fact that people who have reached some success get tons of time to just relax, but only because they’ve earned it ! If you haven’t built a successful business, or in some way built a career that allow you so much freee time, then you are stuck in the grinding world of nine-to-five jobs everyone else. So how comfortable is that ?

So what can you do about it ? Well, find a way to make something happen in your life--- build a business around your favourite hobby, write a book and publish it, or take a course in stock trading and become an expert at that, working on making enough money to retire. If you don’t take massive action that puts your way of your comfort zone, you will never be successful at much of anything. I promise--- and I don’t make many promises !

Finding real happiness in life can be a mystery for many. That’s why I wrote The Road to Happiness for those who want real success and happiness in life, including spirituality and all the gifts life has to offer.

Don’t wander aimlessly through life. Get focused on your goals, start helping others in need, and live life to the fullest ! Life is too short to be anything but happy.

A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth．

Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）．

But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works．

The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it．This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence．

First they measured fluid intelligence of volunteers using standard tests．Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard．During the course, they needed to ignore irrelevant items, monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time．

The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively．To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training．

The results, published Monday in The Proceedings of the National Academy of Sciences，were striking．Improvement in the trained groups was a lot greater．Moreover，the longer they trained, the higher their scores were．All performers，from the weakest to the strongest，showed significant improvement．

“Our results show you can increase your intelligence with proper training．” said Dr Jaeggi, a co-author of the paper．“No one knows how long the gains will last after training stops,” he added, “and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains．

1.By writing the article，the writer intends to ______________．

A. inform the readers of a new study

B. call on people to be trained to increase intelligence

C. prove one’s born brainpower can be improved

D. tell people the improved intelligence will last forever

2.The researchers thought the key to improving the intelligence was ______________．

A. memorizing telephone numbers　　　

B .improving working memory

C. training in concentration　　　　　　　

D. recalling a card

3.The following aspects of the training help increase intelligence EXCEPT___________．

A. ignoring irrelevant items　　　　　　　　

B.monitoring ongoing performance

C.managing two tasks at the same time　　

D.using previous experience

4.When the experiment was conducted, the researchers______________．

A.trained the four groups for the same period of time

B.only made comparisons between the four groups

C.compared the four groups with control groups

D.trained the four groups together
