Although most games have winners and losers, the goal of sports is not to win every game. The real goals include getting exercise, having fun, and learning important social skills, like good sportsmanship.

    Good sportsmanship is all about respect. Good sports (具有运动家品格的人) respect their teammates and also their opponents. They respect their coaches, and they also respect the referees or other officials involved in their games. {#blank#}1{#/blank#} They yell at their teammates and they talk back to coaches or referees.

    Kids usually learn sportsmanship — good and bad — from the adults in their lives. {#blank#}2{#/blank#} If parents and coaches show disrespect to other fans, referees, or each other, kids will likely act the same way on the field.

    {#blank#}3{#/blank#} Some of them are very basic and easy to do, like shaking hands with other players before a game. Other examples may take a little more courage, such as acknowledging a great play made by the opposing team.

    Learning good sportsmanship is important because it helps you develop an attitude of graciousness (礼貌) and respect that will carry over into all the other areas of your life. {#blank#}4{#/blank#} Being a good sport in the classroom will eventually lead to being a good sport in the workplace.

    So be a good sport in whatever you do！ {#blank#}5{#/blank#} When others see you acting in a way that makes it clear that winning isn't the most important thing, you can move on to focusing on the important things, like having fun, getting exercise, and improving your skills!

A．Good sportsmanship can be shown in many ways.

B．On the contrary, bad sportsmanship is all about disrespect.

C．The example you set can be a powerful teaching tool for others.

D．Players' parents and coaches set examples that kids tend to follow.

E．We can be good sports by encouraging others but not laughing at them.

F．Starting as a good sport earlier will help you be a good sport as you get old.

G．If you're a good sport on the field, you'll also likely be a good sport in the classroom.

    Wouldn't it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language?

    In a recent Wall Street Journal article, technology policy expert Alec Ross argued that, within a decade or so, we'll be able to communicate with one another via small earpieces with built-in microphones. That's because technological progress is extremely rapid. It's only a matter of time. Indeed, some parents are so convinced that this technology is imminent that they're wondering if their kids should even learn a second language.

    It's true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “No es bueno dormir mucho” as “It's not good to sleep too much.” Replacing a word with its equivalent (同义词) in the target language is actually the “easy part” of a translator's job. But even this seems to be a discouraging task for computers.

    It's so difficult for computers because translation doesn't—or shouldn't—involve simply translating words, sentences or paragraphs. Rather, it's about translating meaning. And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time.

Think about all the related clues that go into understanding an expression: volume, gesture, situation, and even your culture. All are likely to convey as much meaning as the words you use.

    Therefore, we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.

    For those concerned about wrinkly old skin, It might be a creative solution: an elastic(有弹性的) “second skin” that can be smoothed on to make aged tissue look more youthful.

    The wearable film, developed at the Massachusetts Institute of Technology (MIT), has shown promise in a series of small experiments where it was applied to wrinkles, under-eye bags and areas of dry skin. When applied to the face or body, the thin, transparent layer sticks to the skin and supports the tissue, making it look and behave like younger skin, its producers claim.

    “What we've been able to do is create a cream that you can put on the skin, and then when it's on the skin it can actually form, essentially, an elastic second skin,” said Bob Langer, who led the research. Tests in the lab found that the polymer film (高分子膜), which is only 70 thousandths of a millimetre thick, reduced the appearance of wrinkles and under-eye bags, and helped keep moisture in areas of dry skin.

    The layer is designed to be applied in the morning, then peeled off at night. In previous studies, the second skin withstood normal daily wear, and the stresses and strains of exercise and swimming, without falling off or causing irritation. It also survived exposure to rain.

    “It's something you can wear for a whole day or longer, depending on the physical forces thatget applied to the area where it is worn, "said Daniel Anderson, who helped develop the product at MIT. “You can't tell you're wearing it.”

    While normal cosmetics can mask imperfections on the skin, the new coating changes the way skin behaves by giving it the elasticity of young skin. It was developed with help from two companies.

    One of the most striking findings of a newly research in the UK is that of the people interviewed, one in two believes that it is becoming more difficult to meet someone to start a family with.

    Why are many finding it increasingly difficult to start close relationships? Does modem life really make it harder to fall in love? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for money or status. A man doesn't expect his wife to be in (唯一的) charge of running his household and raising his children.

    But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence.

    In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soul mate was limited by geography, social convention and family tradition. Although it was never clear，many marriages were essentially arranged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster ( 牡蛎), you surely have a better chance of finding a pearl.

    But it seems that the old conventions have been replaced by the limitations of choice. The expectations of partners are raised to an unmanageable degree: good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression.

    We think that a relationship can be perfect. If it isn't, it should be ended. We work to protect ourselves against future heartache and don't put in the hard emotional labor needed to build a strong relationship. Twelve-hour work at the office makes relaxed after-hours dating difficult. The cost of housing and child-raising creates pressure to have a stable income and Career before a life partnership.

    The world is a greener place than it was 20 years ago. A study published in the journal “Nature Sustainability” said that recent satellite data reveals a greening pattern that is strikingly prominent in China and India. The study shows that human activity in China and India dominates this greening of the planet, thanks to tree planting and agriculture. The effect comes mostly from ambitious tree-planting programs in China and intensive agriculture in both countries.

    “China and India account for one-third of the greening,” said lead author Chi Chen of Boston University. “ That is a surprising finding, considering the vague idea of land degradation (毁坏) in populous countries from overexploitation,” added Chen.

    China alone accounts for 25 percent of the global net increase in leaf area with only 6.6 percent of global vegetated area. The greening in China is from forests (42 percent) and croplands (32 percent), but in India, it is mostly from croplands (82 percent) with minor contribution from forests (4.4 percent).

    China's outsized contribution to the global greening trend comes in large part from its programs to conserve and expand forests with the goal of preventing land degradation, air pollution, and climate change.

    “Once people realize there is a problem, they tend to fix it,” said Rama Nemani, research scientist and co-author of the study. “In the 1970s and 80s in India and China, the situation around vegetation loss was not good. In the 1990s, people realized it, and today things have improved. Now we see that humans are contributing.”

    Land area used to grow crops is comparable in China and India—more than 770, 000 square miles—and has not changed much since the early 2000s. Yet these regions have greatly increased both their annual total green leaf area and their food production.

    This was achieved through multiple cropping practices, where a field is replanted to produce another harvest several times a year. Production of grains, vegetables, fruits and more have increased by about 35%～40% since 2000 to feed their large populations.
