Looking good can matter a lot when you are a teenager. Of course the budget(财政） matters a lot, too. Luckily, fashion trends (流行趋势) in the UK mean that getting the right image doesn't have to cost the earth. Here's a quick guide to which looks are hot this year.

    For girls, the 70s are back. Wide-legged jeans, platform shoes and skirts that reach the feet are again in fashion among UK teens, topped off with colored, shining eyeshadow. Girls can have fun mixing and matching bright shades. Colors like pink, orange and light yellow-green are all perfectly fit. Shorts and mini-skirts are still popular in cold weather. By wearing a pair of tights underneath ( 在..底下), girls can stay warm as well as fashionable in the winter.

    How about boys? To look lively, fans of skateboards and snowboards can dress in skinny jeans accompanied by a T-shirt topped off with a baseball cap or a woolen hat. Music is often an inspiration for fashion, and hip-hop music fans like to dress in baggy jeans, T-shirts, baseball caps and sneakers. For those who can afford it, designer clothing is a must, especially if the logo is showing.

    Do you want to live forever? By the year 2050,you might actually get your wish-if you are willing to leave your biological body and live in silicon circuits (半导体电路). But long before then, perhaps as early as 2020,some measures will begin offering a semblance of immortality (虚的永生).

    Researchers are confident that the technology will soon be able to track every waking moment of your life? Whatever you see and hear, all that you say and write, can be recorded, analyzed and added to your  personal chronicles (履历). By the year 2030, it may be possible to catch your nervous systems through electrical activities, which would also keep your thoughts and emotions.

    Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher. Small electronic equipment will make preparation for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to microseosors under your scalp (头皮) and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.

    At first, the Soul Catcher's companion system-the Soul Reader-might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand how the brain is working inside, so reading your thoughts and understanding your emotions might not be possible. But these signals could be kept for the day when they can be transferred to silicon circuits to revitalize minds everlasting entities (永生实体). Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.

For people who choose not to live in silicon, semblance of immortal it would not be as useless as they thought. People would know their lives would not be forgotten, but would be kept a record of the human race forever. And future generations would have a much fuller understanding of the past. History would not be controlled by just the rich and powerful, Hollywood stars, and a few thinkers in the upper society.

    Summer heat can be dangerous, and heat leads to tragedy far too often. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.

    For Bishop Curry, a fifth grader from McKinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch(草图) of a device he called "Oasis."

    The device would attach to car seats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the car seat, it would begin to circulate cool air. Curry also designs the device using GPS and Wi-Fi technology, which would alarm the child's parents and, if there was no response from them, the police.

    Curry's father believes that the invention has potential. "The cool thing about Bishop's thinking is none of this technology is new," he said. "We feel like the way he's thinking and combining all these technologies will get to production faster." His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.

    In January, Curry's father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis' potential that they have raised more than twice that--over $46,000.

    Curry's father remembers the first time he saw his son's sketch. "I was so proud of him for thinking of a solution," he said. "We always just complain about things and rarely offer solutions."

    What do Leonardo da Vincii, Marie Curie, and Albert Einstein have in common? They were all left-handed, along with other famous people including Brad Pitt Prince William, and Barack Obama. In fact, an estimated 13 percent of the world's population may be left-handed and still most people around the world are right-handed.

    What makes a person become right-handed rather than left-handed? As yet no one really knows for sure. One simple idea suggests that people normally get right-handedness from their parents. Studies have found that two right-handed parents have only a 9.5 percent chance of having a left-handed child, whereas two left-handed parents have a 26 percent chance of having a left-handed child. Another common theory is that left-handed people suffer mild brain damage during birth, which makes them left-handed. However, if this theory were true, it would not explain why the percentage of left-banded people is so similar in every society, when birth conditions vary so much from society to society.

    Whatever the reasons behind it, people's attitudes toward left-handedness have changed a lot over the years. Statistics show that although 13 percent of young people (10-20 years old) are left-handed, only 6 percent of the elderly are left-handed. Left-handed children used to be punished until they began using their right hand like other children, but today people who are left-handed are no longer looked down on nor are they considered abnormal. For most people today, either case is perfectly acceptable.

    Craft (手工艺）is becoming a heritage industry — but a record of disappearing skills might just come in handy in the future.

    Mr. Lobb (of John Lobb the bootmaker) mentioned that custom clothing and shoe-making were once the norm for everyone. How come，then，today a pair of normal Lobbs would set you back over £2,000? The price has obviously gone up because of lack of competition and higher wages，but would custom clothing once again be affordable to all if the demand was there? Do we just wave goodbye to these skills，or should we fight to maintain them?

    The disposable (一次性的）culture we “enjoy” today has existed in our life for almost two generations now. We like our products to be made by either a robot or invisible，cheap hands so that we can accumulate them cheaply and frequently. The concept of “craft” is something that's now largely considered to be strange，and seems to be limited to museums and dusty, independent shops. Hobby crafts such as knitting do undergo revivals (复兴)from time to time，but I think that's because they are seen as short-lived fashionable leisure pursuits rather than a craft worthy of revivals on a commercially feasible (可行的)scale.

To drive a revival in any of these crafts, you would probably need to apply the same marketing techniques that are used to sell any other items today. The consumer must believe that they just have to have it. If they don't have it now, it will either go up in price or go out of fashion — both reasons enough in themselves for a shopper to act.

    But does it finally matter if these skills will no longer serve any practicable use in the decades to come? I don't know the answer to that，but I have long thought it would be a good idea if we “banked” these skills somehow，just as we are not attempting to do with seeds. You just never know whether we'll need them in the future. Maybe it's time to establish a worldwide network of volunteers to record，through the written words and videos，as many of these dying skills as possible. Actually, a rough look on YouTube fills me with hope that an army of willing volunteers is probably out there already and just needs someone or something to gather them together.

    Stephen Hawking is one of the most famous scientists in this century. He was born in 1942. He's world well-known on space and time. Stephen was searching some very big questions, such as "How did the universe begin? How will it end?"

    Stephen was a student at Oxford University. He studied math and science. Then, at the age of twenty, he became sick. He was so young, but the doctors said to his family, "He has only two more years to live." As a matter of fact, the doctors were wrong – he didn't die. He can't walk but he uses a wheelchair. He can't feed himself and get in or out of bed himself. But he refused to give in to the condition. He talks with the help of a computer. After Oxford, Stephen went to Cambridge University. Three years later, in 1965, he became a doctor of philosophy(哲学).

    Because of his serious health problems, it was difficult for him to draw or to write. So he started to think in pictures. With this new way of thinking, he became one of the most famous scientists in the world. In 1981, he met the Pope(教皇) in Rome. They talked about his ideas. Then in 1988, he wrote his first important book, A Brief History of Time. It sold more than 5.5 million copies in 33 different languages. He was once invited to China, he impressed us with his self-confidence, humorous and witty(风趣的) conversation.(谈话)
