There is a lot of misunderstanding about studying. Most students have not been taught the principles behind really effective working. Imagine a graph showing the amount a person learns against the number of hours he works in a day. If he doesn’t do any work, he learns nothing (point 0). If he does an hour’s work he learns a certain amount (point 1). If he does two hours’ work he learns about twice as much (point 2). If he does more work he’ll learn still more (point 3). However, if he tries to do twenty-three and a half hours’ work in a day, he will be so tired that he’ll hardly remember anything: what he learns will be very little (point 4). If he did less work he’d learn more (point 5).
Now whatever the exact shape of the graph’s curve(曲线), made by joining these points, it must have a high point. Point “X” is the very maximum anyone can learn in the day. And this represents the optimum(最适度), the best, amount of work to do. It is the best possible compromise between adequate time at the books and fatigue(劳累). Fatigue is an absolutely real thing; one can’t escape it or ignore it. If you try to ignore it and press yourself to work past the optimum, you will only get on this downward slope and achieve less than the best – and then become very tired and lose your power of concentration.
The skill in being a student consists of getting one’s daily study as near the optimum point as possible. I cannot tell you what the optimum is. It differs with the type of work, it differs from person to person, and even in the same person it varies from week to week. You must try to find your own. Every day you study, bear this principle of the optimum in mind. When you feel yourself getting fatigued, if you find yourself reading the same paragraph over and over again and not taking it in, that’s a pretty good sign you’ve reached your highest point for the day and should stop. Most ordinary students find their optimum at five hours a day. Yours may be a little more or a little less – but if you get in five hours’ good work a day, you will be doing well.
Now, what are you doing with yourself when you aren’t working? Before examinations some students do nothing at all except sit in a chair and worry. Here is another misunderstanding. People often think that the mind works like the body; it does not. If one wanted to save one’s physical energy in order to cut the maximum amount of firewood, one would lie flat on a bed and rest when one wasn’t chopping. But the mind cannot rest. Even in sleep you dream, even if you forget your dreams. The mind is always turning. It gets its relaxation only by variety. That is what makes the mind rest.
When you’ve finished your optimum number of hours you must stop. You must not then sit around in the chair thinking about the work – that only tires without any learning. You must get out and do something. It doesn’t matter what – anything so long as you are actively doing something else but work.

If cars had wings, they could fly and that just might happen, beginning in 2012. The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its car-plane, the Transition, to customers by the end of 2012.
“It’s next ‘wow’ vehicle,” said Terrafugia vice president Richard Gersh. “Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”
The car-plane has wings that unfold for flying-a process the company says takes one minute-and fold back up for driving. A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you’re good to go. When you land, you hold up the wings and hit the road. There are no expensive parking fees because you don’t have to store it at an airport-you park it in the garage at home.
The car-plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Thrrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal(临界的) conditions.
The Transition’s price tag: $194,000. But there may be additional charges for options like a radio, , a transponder or a GPS. Another option is a full-plane parachute.
“If you get into a very awful situation, it is the necessary safety option.” Gersh said.
So far, the company has more than 70 orders with deposits. “We’re working very closely with them, but there are still some remaining steps,” Brown said.
【小题1】We can learn from the first two paragraphs that _________.
| A.car-planes will be popular in 2012-4-6 |
| B.people might drive a car-plane in 2012 |
| C.both the Transition and Ferrari can take off and land |
| D.Richard Gersh is the vice president of Massachusetts |
| A.fold and unfold its wings | B.unfold wings for flying |
| C.land in the airport | D.meet flying safety regulations |
A. The car-plane needs a runway to take off and land.
B. To meet aircraft regulations, the company has been working with FAA.
C. The car-plane may fly as high as normal planes.
D. People can park the car-plane in the garage at their home. 查看习题详情和答案>>

Autumn and winter are cold and flu seasons. Will the old advice about dressing warmly help prevent a cold, or if you get sick, should you follow the old saying, “feed a cold and starve a fever?” And what about that fever? Should you take medicine to reduce your temperature, or is it better to let the body treat the fever itself? Everyone seems to have an answer. But is popular wisdom valuable?
Doctor Nelson knows a lot about cold and flu seasons. Nelson says research may be just starting to provide proofs for long-held beliefs. For example, scientists for years were against the idea that getting cold and wet might cause colds or flu. But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses. So maybe it does make sense to wrap up warmly before going outside.
And what about feeding a cold and starving a fever? Nelson says if you have a cold and are hungry, you should eat. But a fever, especially a high one, suggests a more serious problem. He says people are usually not hungry when they have a high fever. Eating might even make a person sick. But drinking enough water is important. A fever easily makes the body lose water.
Finally, when should you treat a fever? Nelson says a fever should be treated if it stays at
40℃ or above for a day or more. A high temperature can damage brain cells. The doctor also believes in treating a fever if it prevents a person from sleeping.
Medicine like aspirin, for example, can be used to reduce pain and fever. But aspirin should not be given to children because it can cause serious problems.

Teachers and parents usually call attention to the pictures when they read storybooks to pre-school children. But a new study suggests that calling attention to the words and letters on the page may lead to better readers.
The two-year study compared children who were read in this way in class with children who were not. Those whose teachers most often discussed the print showed clearly higher skills in reading, spelling and understanding. These results were found one year and even two years later.
Shayne Piasta, an assistant professor of teaching and learning at Ohio State University, was an author of the study. She says most pre-school teachers would find this method manageable and would need only a small change in the way they teach. They already read story-books in class. The only difference would be increased attention to the printed text. “If you get children to pay attention to letters and words, it makes sense that they will do better at word recognition and spelling.” But she says research suggests that very few parents and teachers do this in a systematic way.
More than 300 children aged four and five were observed in classrooms. They came from poor families and were below average in their language skills. For thirty weeks, the children took part in a program called Project STAR--- Sit Together and Read. The project is based at Ohio State. It tests the short-term and long-term results of reading regularly to pre-school children in their classrooms.
There are different ways that adults can talk to children about print. They can point to a letter and discuss it, and even trace the shape with a finger. They can point out a word and discuss the meaning of the print or how the words tell the story. And they can talk about the organization of the print--- for instance, showing how words are written left to right in English.
