If you ever visit an English village, make sure to look out for morris dancing. Undoubtedly one of the strangest traditions of English culture, morris dancing is a form of folk dancing that dates back to the 15th century. If you ever get the opportunely, you really have to see it.

    Men and women wearing old-fashioned, shabby clothing dance in the streets of towns and villages across the country during the holiday periods. Women wear long, frilly(有褶皱边的) skirts and men wear short trousers with bells attached to them. They dance to traditional folk music which is often played on traditional musical instruments.

    Some groups carry heavy black sticks which they beat against each other while they dance. Other groups wave handkerchiefs in the air while they perform. The dances are usually performed near a pub so that when it's over, the dancers and audience can sing some traditional folk songs over a pint of beer. The celebrations will often continue long into the night, by which point most people are too drunk to think about performing again.

    Morris dancing is a great English tradition but it's facing a big crisis. As the years go by, fewer and fewer young people are joining morris dancing groups. The dancers are getting older and older and eventually, if nothing is done to change this trends, the tradition will die out within the next few decades.

    If you've ever had the fortune to see morris dancing, you may understand why teenagers aren't rushing to sign up. Putting it to the point, it's not exactly the coolest thing for an 18-year-old to be doing. Why dress up in bells and funny costumes when you could be going clubbing? Or playing sport? Or doing anything else?

    However, it would be a great shame to lose such a fun and lively part of England's history and culture. It's important to look after some traditions and customs especially when it's something as harmless and happy as morris dancing. So here's a toast to the next generation of would-be morris dancers! Let's hope they don't leave it too late.

    For thousands of years, we have looked for ways to measure time. Early humans found that the regular movements of the sun, the earth> the moon, and the stars made good ways to measure time. The rising and setting of the sun were used to distinguish (辨别) day from night.

    But, eventually, people needed to tell time more accurately, or exactly. So, by using the sun's position in the sky, they divided the day into dawn, morning, midday and evening.

    Then it was noted that the sun cast a changing shadow as it moved across the sky. Time could be told more accurately by setting up a stick and marking the positions of the sun's shadow. It was the ancient Greeks who divided each position of this “sundial (日晷)” into hours.

    But the sun doesn't always shine. So, for the past 6,000 years, many other ways of keeping time have been tried. Slow-burning candles were divided into hours, and the hourglass was invented. When all the sand in the top of an hourglass has shifted to the bottom, an hour has passed.

    Later, the pendulum (摆钟), with its regular back-and-forth movement of weights, was used to move the hands on a clock. Pendulums are still used in grandfather clocks.

    Today, even more accurate clocks are in use, such as battery-operated quartz clocks (石英钟), digital clocks, and clocks run by electrical tuning forks and tiny atoms. These atomic clocks are the most accurate clocks ever invented. The exact time can be kept to within 1 second a century.

    Life is filled with regrets. {#blank#}1{#/blank#}When we look back, we always wish that we had made better choices. Then what can we do to avoid future regrets？

How to stay focused in class

    Being relaxed during class is a bad habit, and it is also bad to your grade. Focusing in class not only proves to teachers that you are a capable student but also shows that you have the ability to control yourself, which will be very important.

    {#blank#}1{#/blank#} No matter how much you want to sit with your friends during the class, try your best to avoid them. Talking with friends around you is not going to give you the focus in class. This will get you into trouble.

    Look at teacher and make eye contact. Your teacher is not just standing up there talking.{#blank#}2{#/blank#} Show the teacher that he or she has your full attention by looking them in the eye. This person should have your full attention at all times during class.

Take notes. By taking notes, you'll be able to "get into" the lesson. Write down key points as your teacher speaks. And listen to the key phrases such as "This is important" "This is the main idea" "This will be the test" etc.{#blank#}3{#/blank#}

    Get involved in class discussions. This is a wonderful way to become a more focused, successful student. When a teacher asks a question, offer to answer it.{#blank#}4{#/blank#} This shows the teacher that you are listening carefully during the class.

    Ask a question.{#blank#}5{#/blank#} This really shows your teacher that you want to be better, and can recognize the things you are having difficulty with. Chances are that someone else in the class has the same question （and was too afraid to ask!）. They'll be relieved, and so will you.

A. Avoid sitting with friends.

B. This can help you listen more attentively.

C. If he or she ask for an opinion, share your own.

D. Talking with friends makes you lose interest in class.

E. He or she is trying to give you an acceptable education.

F. The more quickly you answer, the more attention you pay.

G. If you don't understand something, never be afraid to ask.

    A new Magic Bench designed by Disney Research lets you interact (互动) with lovely animated (动画的) character—and no special glasses or earphones are required. Instead, the complete environment-the seat, the sitter and the cartoon characters-is mirrored on a screen opposite the bench making it possible for others to watch the scene unfold.

    How does the illusion work? A camera and sensor catch images and gather depth information about physical objects the bench and the person. And then computer translates them into the 3D animations. Meanwhile sensors of touch built into the bench deliver shaking that is happening at the same time and speed to animated actions on the screen, creating the illusion that the animated figures are occupying real-world space next to the user.

    "Our goal for this project was: hear a character coming, see them enter the space, and feel them sit next to you," said Moshe Mahler, principal digital artist at Disney Research. Unlike the traditional mobile technology, one of whose limitations is that only a single user can see its illusion, the Magic Bench allows groups of people to gather in a single environment and collectively participate in an augmented—reality (扩充实境) experience, all at the same time.

    In a video show, a small cartoon donkey runs into view and kicks the bench, causing sharp sound and making the seated person jump in surprise. Another test shows two people on the bench, reacting as they feel an animated rabbit skip up beside them and jump up and down. When a user passes his hand over the rabbit, a shadow moves across its head, as though it were occupying the same physical space as the person next to it.

Customs on either side of the Atlantic

    We all know that Britain and the US are two countries connected by a common language. But in fact, {#blank#}1{#/blank#} as BBC did in a recent story called 8 Situations When Britons Behave Differently From Americans. Below Teens has picked out four for you. Take a look.

    When someone knocks into you.

    If someone bumps into an American, the victim will most likely look the accidental aggressor in the face and expect an apology. If however, {#blank#}2{#/blank#} chances are that the victim will say "sorry" before the other can make his or her own apology.

    {#blank#}3{#/blank#}.

    Britons don't all change into evening dress for supper like what you may have seen in popular TV shows like Downton Abbey. But they do tend to make an effort when going out for dinner somewhere nice. Americans, however, will probably wear a casual shirt to a fancy eatery.

    When you drift finish your food.

    When dining out at a restaurant, {#blank#}4{#/blank#}. They think the food is somehow "tainted" once they've poked at it with a knife and fork. In the US, wrapping it up to take home is a standard practice.

    When you get into a taxi.

    Britons will give the cab driver an address, then assume that's it for the interaction until it's time to pay. Even if they're being taken in a roundabout way, {#blank#}5{#/blank#}. In the US, however, most passengers think nothing of telling the driver what route to take after telling him or her the destination.

A. When you get dressed for dinner

B. When you go out with your friends

C. the differences are more fun to observe

D. they're very unlikely to say anything

E. the victim happens to be British
