READY or not, the college application season has begun. There are two main kinds of early admissions programs: Early Action and Early Decision.

    Early Action is a great choice for the well-prepared student. Students apply early, and are allowed to apply under an Early Action program to as many colleges as they choose. The biggest advantage for students is that colleges let them know early – in most cases, before Jan 1. Roughly 15 percent of colleges and universities offer an Early Action option(选择). Oct 15 is now the first deadline for many colleges and universities. This movement toward earlier deadlines is especially popular in the Southeast, with many of the large public universities leading the way. North Carolina State University, the University of South Carolina and the University of Georgia all have an Oct 15 Early Action deadline.

    Early Decision is a promise that cannot be reversed. Students who are accepted must take back their other applications and should attend that school. Students are allowed to apply to just one school under an Early Decision program. Early Decision deadlines are in early November, with colleges letting students know by mid-December. Many students believe that they are more likely to be accepted if they apply for Early Decision, but it actually depends.

       In some cases there is big increase in students being accepted, and at other colleges it is not that big at all. Generally, the strongest students are applying early. Athletes and students with focused interests are encouraged to apply for Early Decision.

    Cold weather during winter months may keep many people from leaving home and running in the open air.

    However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one's performance.

    Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.

    That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body's dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.

    This information comes from sports scientists at St. Mary's University in London. John Brewer is a professor of applied sport science at St. Mary's.

    For this study, he and other researchers put a group of people into a room they called an "environmental chamber." The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.

    "We've got a group of subjects into the environmental chamber, we've changed the conditions to replicate the summer or winter and we've got them to run a 10km under both of those conditions and taken various measurements on each runner while they've been completing their 10km."

    Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.

    More than a hundred years ago, two boys were fishing in a small river. They sat in a heavy-bottomed boat, each holding a long, bent pole in his hands and eagerly waiting for "a bite". When they wanted to move the boat from one place to another they had to push against a long pole into the bottom of the stream.

    "This is slow work, Robert," said the older of the boys. "Yes, Christopher, and it's hard work, too." answered Robert. "I think there's some better way of moving a boat."

    Christopher advised rowing it and Robert promised to make some paddles (桨). The next day Robert's aunt heard a great noise in her house. The two boys were there, busily working. "What are you making, Robert?" she asked. He told his plan. His aunt laughed and said, "Well done! I hope you'll succeed."

    After much work, they succeeded in making two paddle wheels. They were very rough, but strong and usable. They fixed each of these wheels to the end of an iron rod (长杆) which they passed through the boat from side to side. The rod was bent in the middle. When the work was finished, the old fishing boat looked rather strange, with a paddle wheel on each side. The boys lost no time in trying it. One of the boys could guide the boat while the other turned the paddle wheels.

    That night when Christopher went home, he told his father a wonderful story. "Robert Fulton planned the whole thing," he said, "and I helped him make the paddles and put them on the boat." When Robert Fulton became a man, he didn't forget his experiment with the old fishing boat. He kept on thinking and working, until at last he succeeded in making a boat with paddle wheels that could be run by steam. He's now honored as the inventor of the steamboat.

    A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy (精确) and speed, The Telegraph reported.

    Perhaps, some parents disagree with this idea, saying, "Switch off the music and concentrate!" Well, if that's the case with your parents, you might now be able to convince them that you have science on your side.

    The company gave 26 participants（参与者）a series of different tasks for five days in a row, including spell checking, mathematical word problems, data entry, and abstract reasoning. The participants completed these tasks while listening to music or no music at all.

    The results showed that while music was playing, 88% of participants produced their most accurate test results and 81% completed their fastest work. David Lewis, chairman of Mindlab International, told The Telegraph, "Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state... they are going to become more positive about the work."

    However, you may have a list of your favorite songs, but not all kinds of music match all homework. For maths or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. In the study, pop music enabled participants to complete their tasks 58% faster than when listening to no music at all. If you are reviewing your English writing, pop music is the best choice, as it is the best kind for spell checking. It cut mistakes by 14%, compared to listening to no music. After finishing your homework, do you often take time to check your answers? Maybe, some dance music is suitable for you.

    Once upon a time, two brothers who lived on neighboring farms fell into conflict(冲突) . It was the first serious one between them in 40 years of farming peacefully side by side. In the end, they fell apart.

    One morning, a man with a carpenter's toolbox came for some work. The elder brother said, "I have a job for you. Look at the farm across the creek(河沟). My younger brother lives there. It was he who used his bulldozer(推土机)to dig the creek last week to spite(刁难) me. So I want you to build me a fence, an 8 – foot – high fence, in order not to see his place any more." The carpenter smiled and said, "I see. I'll try to do a job that satisfies you." Then the elder brother went downtown.

    At sunset when the farmer returned, the carpenter had just finished his job. The farmer's eyes opened wide! To his surprise, there was no fence there at all! Instead, there was a bridge stretching from one side of the creek to the other! A fine piece of work! He saw his younger brother coming to him with the hands outstretching. The brothers stood at each end of the bridge, and then they met in the middle, taking each other's hands. They turned to see the carpenter lift his toolbox on his shoulder.

"No, wait! Stay a few days. I've a lot of other work for you," said the elder brother. "I'd love to stay on," the carpenter said, "but I have so many more bridges to build."

    Science has a lot of uses. It can uncover laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation(诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

    Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't?

    To answer these questions, Brooks surveys a wide range of disciplines(学科). Considering this, you might expect the book to be a dry recitation of facts. But Brooks has structured his book in an unorthodox(非常规的), and perhaps unfortunate, way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

    On the whole, Brooks' story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong or memorable characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks' attempt to translate his tale into science.
