Thinking is basically a of making connections in the brain.

I found out one time that doing a favor for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.
Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed（解散）. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible for your own acts. For a long time, she talked about honesty and emphasized the fact that when people do something dishonest, they are really cheating themselves. She made me promise that I would think seriously about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.
Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued to believe that I had cheated on the test.

By the mid?nineteenth century, the term “icebox” had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in places like hotels and hospitals, and by some forward?looking city businessmen in fresh meat, fresh fish, and butter. After the Civil War (1861～1865 ), it also came into household use. Even before 1880, half of the ice sold in New York, Philadelphia, and Baltimore, and one?third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, early form of the modern refrigerator，had been invented.
Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, people only had some simple and basic knowledge of the physics of heat. The common idea that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Early efforts to save ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance needed for an efficient icebox.
But as early as 1803, a Maryland farmer, Thomas Moore, had been in the correct direction. He owned a farm and used an icebox of his own design for the transportation of his butter to a market in the village of Georgetown. And there he found that customers would pass up the rapidly melting goods of his competitors to pay a higher price for his butter, still fresh and hard in neat, one?pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.As a result，Moore managed to earn a large sum of money.

People talk about energy everywhere. Green energy, for example. Then, energy independence. It has a nice ring to it. Doesn’t it? If you think so, you’re not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession(经济衰退).
"Energy independence" and its rhetorical(修辞的) companion "energy security" are, however, unreliable concepts that are rarely thought through. What is it that we want independence from, exactly?
Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that oil from elsewhere.
The first reason is that we need it to keep our economy running. Yes, there is a trickle(涓涓细流) of biofuel(生物燃料) available, and more may become available, but most biofuels cause economic waste and environmental destruction.
Second, Americans have basically decided that they don’t really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to tolerate the environmental influence of domestic(国内的) energy production in order to cut back imports?
Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don’t read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.
There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to keep its economy stable. When that flow is interrupted, we feel the pain in short supplies and higher prices. At the same time, we get massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.
1.What does the author say about energy independence for America?
A. It sounds very attractive.
B. It ensures national security.
C. It will bring oil prices down.
D. It will protect the environment.
2.Why does America rely heavily on oil imports?
A. It wants to expand its storage of raw oil.
B. Its own oil reserves are quickly running out.
C. Its own oil production falls short of demand.
D. It wants to keep its own environment untouched.
3.What does the author say about oil trade?
A. It improves economic efficiency.
B. It makes for economic recession.
C. It brings benefit only to the sellers.
D. It saves the cost of oil exploration.
4.What is the author’s purpose in writing the passage?
A. To explain the increase of international oil trade.
B. To raise Americans' awareness of the energy crisis.
C. To argue for America’s dependence on oil imports.
D. To stress the importance of energy protection.

When you get tired of homework, several minutes’ walk in a nearby green park helps you relax at once. Or you may stand facing the lake or the seas. They will calm (not to be excited or nervous) you just like the green plants.
Wonder why? Color is a key part of the answers. Since it is so, green and blue help make people feel more quiet and safe.
All colors have special power. Scientists have found that many colors have specific effects on people’s mind and feelings.
Try an easy and interesting experiment and you’ll see how color “misleads” you sometimes. Wrap (包装) two boxes of the same size with colored paper, one red and the other white. Then weigh the two boxes with your hands. Which one is heavier? Most people will think that the red box is heavier, even though they weigh the same.
Colors can affect learning. Scientists have found that students spend more time reading if they read information written in blue text. Blue helps most people calm down and think more.
Clever uses of colors in daily life are to be seen everywhere. Hospitals and libraries seldom paint their walls, tables and desks red. They use light colors, like light blue or green. Red makes people excited while light colors help them relax. Haven’t worked out how color affects your daily life? Start with your small room. Try to make some changes in it and you’ll get to know how important color is!
