More than a decade ago, cognitive scientists John Bransfgord and Daniel Schwartz, both then at Vanderbilt University, found that knowledge was not the ability to retain facts or apply previous knowledge to a new situation but a quality they called "preparation for future learning." The researches asked fifth graders and college students to create a recovery plan to protect bald eagles from extinction. Shockingly, the two groups came up with plans of similar quality (though the college students had better spelling skills). From the standpoint of a traditional educator, this outcome indicated that schooling had failed to help students think about ecosystems and extinction, major scientific ideas.
The researches decided to go deeper, however. They asked both groups to generate questions about important issues needed to create recovery plans. On this task, they found large differences. College students focused on critical issues. The college students had cultivated the ability to ask questions, the foundation of critical thinking. They had learned how to learn.
Museums and other institutions of informal learning may be more suitable to teach this skill than elementary and secondly schools. At the Exploratorium in San Francisco, we recently studied how learning to ask good questions can affect the quality of people's scientific inquiry. We found that when we taught participants to ask "What if?" and "How can?" questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit—asking more questions, performing more experiments and making better interpretations of their results. Specially, their questions became more comprehensive at the new exhibit.
This type of learning is not limited to museums of institutional settings. Informal learning environment tolerate failure better than schools. Perhaps many teachers have too little time to allow students to form and pursue their own questions and too much ground to cover in the curriculum. But people must acquire this skill somewhere. Our society depend on them being able to make critical decisions about their own medical treatment, says, or what we must do about global energy needs and demands. For that, we have a robust informal system that gives no grades, takes all comers, and is available even on holidays and weekends.

It seems that the great desire among the young is to be popular. The desire to be popular can force you into looking and acting like everyone else. You can lose yourself in a sea of identical hairstyles and thinking styles.
I was forced to think about popularity not too long ago in a talk I had with my daughter. Margy had to change schools when my busy work schedule made it necessary for me to move houses. I suppose that, for a girl in her teens, entering a new school is like spending a season alone in the tropical jungles. At least that’s how Margy found it at first. However, as the school year drew to a close, one student after another came to her. I told Margy that I would have been more concerned if she had been an instant social success in her new school. Nobody can please everyone. If you try to do so, you will find values as lasting as soap bubbles blown into the air.
Some teenagers claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up listening to the same record. Their reason for thinking or acting in a certain way is that the crowd is doing it. They have come out of their cocoon into a larger cocoon.
I know that it has become harder for a young person to stand up against the popularity wave. Our way of life makes a young nonconformist stand out like a Martian. These days there’s a great barrier for the young person who wants to find his or her own path. But the barrier is worth climbing over. You may want to listen to classical music instead of going to a party. Well, go to it. Be yourself. Popularity will come with the people who respect you for who you are. That’s the only kind of popularity that really counts.

Ever feel like you’ve been hit on the head after a bad night’s sleep? According to scientists, the thought isn’t as unbelievable as it seems.
A study found going without sleep for just one night causes changes in the brain similar to those that occur after a blow to the head. The researchers said the healthy young men examined in the study showed a sudden increase in the same chemicals which indicate brain damage. Professor Christian Benedict, of Uppsala University, Sweden, explained that the chemicals NSE and S-100B are biomarkers for brain damage, such as concussion(脑震荡). He said, "What we found was their levels in the blood rose in the group that went without sleep for a night. This was not to the extent that would happen after a head injury, for instance, but it was still significant. During sleep, the brain cleans poisonous substances off itself."
Benedict also said previous studies which linked a lack of sleep with increased risk of Alzheimer’s, Parkinson’s and multiple sclerosis could applaud his study. The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep contributes to a loss of brain tissue, he explained. Benedict, whose study is published in the journal Sleep, added, "In conclusion, the findings of our experiment indicate a good night’s sleep may be critical to maintaining brain health."
A third of the UK population suffer from sleep-related problems, while the average person now sleeps for only seven hours a night, compared with almost nine a few decades ago. Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart disease, while less than eight hours’ sleep a night can lower the IQ the next day.
1.If you don’t sleep for a night, what will happen?
A.NSE and S-100B will increase.
B.The brain damage will be likea head injury.
C.You will suffer from concussion.
D.The brain will get rid of poisonous substances.
2.What do we know about previous studies?
A.They found reasons for brain disorders.
B.Their findings were published inSleep.
C.They were supported by Benedict’s study.
D.They focused on brain health.
3.What can we infer from the last paragraph?
A.UK people have the worst sleep.
B.Man’s intelligence is affected by sleep in a way.
C.People were smarter in the past.
D.A lack of sleep causes all brain-related problems.
4.What’s the main idea of the passage?
A.Eight hours’ sleep is important.
B.Regular sleeping patterns improve health.
C.Sleep loss is close to a blow to the head.
D.Human brains work during sleep.
We may not be aware of it, but ordinary family homes in the U.S. and the rest of the world are not energy-efficient.
Most of their energy goes to heating and cooling, and a lot of it is wasted, as warm air and cool air escape through fireplace chimneys and thin or poorly fitting windows and doors. A passive house loses almost none."Imagine a thermos(保温瓶),"said housing developer Brendan O’Neill."You have insulation(隔绝) everywhere, and it’s basically completely sealed. And so the idea is to build a house like a thermos. So the windows are sealed. There’s insulation completely surrounding the building. We make it as sealed as possible."
A 147-square-meter passive house, presented by O’Neill Development Corp. as a demonstration unit just outside Washington, was brought to the site in two boxes. "Once it’s set and put together, it takes about four weeks to complete the outside construction, to put down carpets," O’Neill said. "If everything is set in place, you put a house like this together in about four months.”The total cost of building it was $325,000, or about 17 percent more than constructing an ordinary house. But its utility(公用事业) bill is only around $20 monthly, or one-tenth the amount for the average house of the same size.
While passive houses have been around for a long time, the idea has never taken root in the U.S. There was no driving force to push it.
However, David Peabody, an architect who designs passive houses said, "I think climate change is now becoming a larger issue. And I think building standards are catching on to that. So people are becoming more aware of energy."Peabody said the cost of building passive houses could come down."What really makes sense for truly affordable housing," he said, "is to build multi-storey buildings."
1.Why aren’t ordinary family homes energy-efficient?
A. Building them wastes much energy.
B. Their energy mainly goes to heating and cooling.
C. Their sealing performance is poor.
D. They have no insulation around at all.
2.What is the feature of a passive house?
A. There’re no windows or chimneys.
B. There’s little space to place furniture.
C. Its building cost is relatively high.
D. It takes about four weeks to build one.
3.What’s David Peabody’s attitude to the future of the passive house?
A. Cautious.B. Optimistic.C. Skeptical.D. Concerned.

John, a heavy smoker, once feel bad-tempered. His hands started shaking and he coughed a lot, so he turned to his doctor for help. “Quit smoking,” the doctor advised. Find the advice sensible from several points, such as money, healthy, and cleanliness, John decided to give up smoking. However, for several hour without a cigarette, John was nervous and had a difficulty in concentrating, inability to sleep, what made him more hungry for a cigarette. He said to himself, “One more, I will quit it tomorrow. Tomorrow will be a suitable day of me to break away from the bad habit…” Then he picked up a cigarette which made her relaxed.
