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______.

My wife and I used to feel that it was impossible to be a true friend to someone whose name we didn’t know. How wrong we were! Years of Sunday-morning bus trips through the city with the same group of “nameless” people have changed our thinking. Before the bus takes off, we all join in a conversation: where’s the silent woman who sits up front and never responds to our cheery greetings? Here she comes. Her worn clothing suggests she doesn’t have much money to spare, but she always takes an extra cup of coffee for the driver.
We get smiles from a Mexican couple as they get on the bus hand in hand. When they get off, they’re still holding hands. The woman was pregnant late last year, and one day her change of shape confirmed that she’d delivered the child. We even felt a little pride at the thought of our extended family.
For many months, our only sadness lay in our inability to establish the same friendship with the silent woman at the front of the bus. Then, one evening, we went to a fish restaurant. We were shown to a table alongside someone sitting alone. It was the woman from the bus.
We greeted her with friendly familiarity we’d shown all year, but this time her face softened, then a shy smile. When she spoke, the words escaped awkwardly from her lips. All at once we realized why she hadn’t spoken to us before. Talking was hard for her.
Over dinner, we learned the stay of a single mother with a disabled son who was receiving special care away from home. She missed him desperately, she explained. “I love him… and he loves me, even though he doesn’t express it very well,” she murmured. “Lots of us have that problem, don’t we? We don’t say what we want to say, what we should be saying. And that’s not good enough.” The candles flared on our tables. Our fish had never tasted better. But the atmosphere grew pleasant, and when we parted as friends—we shared names.All the following statements can describe the woman except ______.

Squirrels often communicate with whistles, chirps and chucks, which sound like the word “chuck”. Whistles and chirps are like the sounds that many birds make. Now scientists have translated some of their squirrel-speak.
Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls. The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍）their responses. Some squirrels lifted their heads up and became alert(警惕的）. Creatures that were more frightened simply ran for their lives and dived into caves.
"In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger. ' " Hare told. Discovery News.
Hare and some other researchers believe such sounds are part of an advanced language that develops just as all other communication systems.
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behavior, thus increasing the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too. According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms.
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害兽）. Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.The text mainly talks about _______ .
| A．the ways for squirrels to escape from their enemies |
| B．the comparison between squirrels and chickadees |
| C．the calling for the protection of squirrels |
| D．the study on the language of squirrels |
If a squirrel is in a very dangerous situation, it would probably make ____.
| A．whistles with chucks | B．pure chirps |
| C．whistles without chucks | D．repeated chucks |
The underlined word “tidings” in paragraph 6 probably means ____.

What can be learned from this text?
| A．Squirrels communicate with each other as humans do. |
| B．Some squirrels understand the recorded alarm calls. |
| C．Other animals also well understand the language of squirrels. |
| D．Birds such as chickadees don’t have their own language. |
| Café en Seine The wildly luxury (奢华) new art style of this huge bar has been a huge hit since it first opened in 1995, and while it may not be the “in” place it once was, it is still very popular with the after-work crowd and out-of-towners.

We regularly hear how important consumer spending is for the economy. The story goes like this：the more consumers spend，the more money circulates in the economy, which contributes to healthy job growth and profits. Keynes, a British economist，went as far as to say that individuals saving their money may actually be hurting the economy. Sounds troubling, doesn’t it?
Fear not. You aren’t actually hurting anyone else by saving money. Strong economic growth only comes from one place：savings. Not consumption. In fact，economic activity should not be mistaken for economic growth. For example，somebody takes their money, walks into a store, and purchases goods. The store increases its revenue.
But what happens to all of those goods and services that people have chosen not to consume by saving their money? Simple：Other people are allowed to consume them. Think of it this way：When you lend out your savings, you are actually saying，“Here, I am not going to consume right now, so why don’t you?” Banks simply play the middleman：they collect lots of people’s savings and then lend out lots of funds.
It takes an unbelievable amount of goods and services to construct a building. It takes food, shelter, and entertainment for all of the workers, as well. Without savings，it is quite impossible to finance such a construction. The coordination(协调)between savings and consumption is a necessary basis for sound economic growth. This coordination is also why consumer lending (say , to borrow a big sum of money to buy a car) is not productive，in a strict sense. It doesn’t increase the net (净的) amount of wealth of an economy. Those savings could have been used to construct, say, factory equipment.
None of this means consumption and spending are “bad” things. They simply do not make us wealthier. After all, the final goal of production and savings is to consume. But to say that consumption is the engine of economic growth is to put the cart before the horse. Or, to rephrase: the consumption of wealth can never make you wealthier. Happier, perhaps. Wealthier, no.What is the author’s attitude towards Keynes’ theory?
| A．Approving. | B．Reserved(矜持的). |

| D．The Truth about Savings and Consumption |
In her new book, “The Smartest Kids in the World,” Amanda Ripley, an investigative journalist, tells the story of Tom, a high-school student from Gettysburg, Pennsylvania, who decides to spend his senior year in Warsaw, Poland. Poland is a surprising educational success story: in the past decade, the country raised students’ test scores from significantly below average to well above it. Polish kids have now outscored(超过……分数) American kids in math and science, even though Poland spends, on average, less than half as much per student as the United States does. One of the most striking differences between the high school Tom attended in Gettysburg and the one he ends up at in Warsaw is that the latter has no football team, or, for that matter, teams of any kind.
That American high schools lavish more time and money on sports than on math is an old complaint. This is not a matter of how any given student who plays sports does in school, but of the culture and its priorities. This December, when the latest Program for International Student Assessment(PISA) results are announced, it’s safe to predict that American high-school students will once again display their limited skills in math and reading, outscored not just by students in Poland but also by students in places like South Korea, Belgium, the Netherlands, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.
Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader—a mother with three children in the school—was asked about the school’s flaws(暇疵). When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”
One of the ironies(讽刺) of the situation is that sports reveal what is possible. American kids’ performance on the field shows just how well they can do when expectations are high. It’s too bad that their test scores show the same thing.Tom decides to spend his senior year in Poland because _______.
| A．there are striking differences between the 2 countries |
| B．Polish kids are better at learning |
| C．sports are not supported at schools in Gettysburg |
| D．he intends to improve his scores |
According to Paragraph 2, we know that _______.
| A．too much importance is placed on sports in America |
| B．little time is spent on sports in Japanese schools |
| C．American high schools complain about sports time |
| D．PISA plays a very important role in America |
