Good afternoon, and welcome to England. We hope that your visit here will be a pleasant one. Today, I would draw your attention to a few of our laws.

    The first one is drinking. Now, you may not buy wine in this country if you are under 18 years of age, nor may your friends buy it for you.

    Secondly, noise. Enjoy yourselves by all means, but please don't make unnecessary noise, particularly, at night. We ask you to respect other people who may wish to be quiet.

    Thirdly, crossing the road. Be careful, the traffic moves on the left side of the road in this country. Use pedestrian crossing(人行横道) and don't take any chance when crossing the road.

    My next point is about rubbish. It isn't lawful to drop rubbish in the street. When you have something to throw away, please put it in your pocket and take it home, or put it in a dustbin.

    Finally, as regards smoking, it is against law to buy cigarettes or tobacco if you are under 16 years of age.

    I'd like to finish by saying that if you require any sort of help or assistance, you should contact the police, who will be pleased to help you. You can call, write or directly go to any policeman.

    A student is learning to speak British English. He wonders: Can I communicate with Americans? Can they understand me? Learners of English often ask: What are the differences between British and American English? How important are these differences?

    Certainly! There are some differences between British and American English. There are a few differences in grammar. For example, speakers of British English say “in hospital” and “Have you a pen?” Americans say “in the hospital!” and “Do you have a pen?”. Pronunciation is sometimes different. Americans usually sound theirs in words like “bird” and “hurt”. Speakers of British English do not sound theirs in these words. There are differences between British and American English in spelling and vocabulary. For example, “color” and “honor” are British, “color” and honor” are American.

    These differences in grammar, pronunciation, spelling and vocabulary are not important, however. For the most part, British and American English are the same language.

    The American Academy of Pediatrics (AAP) (儿科学) just released its updated guidelines for children's media use.

    The recommendations reflect what all parents know: children need less screen time, which indicates that they desperately need more free time to develop their imagination, a sense of wonder and discover their passion and purpose.

    Our children are over-stimulated, over-scheduled and under pressure to perform academically and beyond school. This weakens their ability to build creative thinking skills essential to self-discovery. Creativity occurs when kids have time for curiosity and exploration. With children spending up to eight hours a day on media devices and additional hours engaging in scheduled activities, opportunities for growth disappear.

    What we are not so sure about is how to get our kids to want the free, screenless time which we know will benefit them. It may sound counter-intuitive (违背直觉的) but today's kids need coaching to experience and discover the benefits of free time.

What came to parents easily a few decades ago has become a challenge for our generation. It's not that yesterday's parents knew more about child development; they simply had fewer choices. Boredom and relaxation were an inescapable part of daily life. Today, they mean, "I'm a bad parent and not doing enough to get my kid ahead."

    Recently, I had an eye-opening revelation while watching my 11-year-old daughter play in a softball game. I have six children and have attended dozens of such game. I know the drill—or thought I did. Families settled in for the day with lawn chairs, cold drinks and cousins. These brothers and sisters would gradually chat with each other. Games of catch and hide-and-seek began, and friendships were formed then. At crucial moments, the newfound friends turned their attention to the field to cheer on their teams.

    But that wasn't happening. Though there were at least 15 children by the sidelines (球场边线), I didn't hear any of them. They sat in silence using their individual tablets (平板电脑). Even with the score tied in the final inning (垒球比赛的一局), not a single child watched the game or spoke to each other. The situation was strange and revealing: Kids have more planned activities and passive entertainment at their fingertips than ever before, but less free time to dream, imagine and focus on what they truly love.

I understand that making time for "nothing" is difficult in a world where we are constantly worried our kids will fall behind if they aren't good at academics. But I refuse to sit back and watch this loss of childhood. We are taking back childhood. Imagination needs time and space to blossom.

If your kids are like mine, asking them to imagine will at the beginning be difficult. That's because they haven't developed the skills and muscle memory to make it second nature. I hope the AAP guidelines prompt all of us to set needed screen time limits for our children. Personally, I am practicing strategies to "develop imagination" in my children. Imagination, like a sport, requires practice, training, motivational speeches, rewards and extreme patience.

    Next morning, there was no wind and we were half a mile from the eastern coast of the island. Although the sun shone bright and hot, I hated the thought of Treasure Island, afraid of what would happen there.

    Guns were given to all the honest men. Hunter, Joyce, and Redruth were told what was happening, and were less surprised than we expected them to be. Then the captain went on deck to talk to the crew.

    They all became happier at once. I think they thought they would find the treasure lying around on the beach! After some talk, six men stayed on board, and the others, with Silver, got into the small boats.

    I then had the first of the mad ideas that help ed to save our lives. If six men were left, we could not take control of the ship; and because only six were left, the captain's men did not need my help. So I quickly went over the ship's side and into the nearest boat.

    No one took much notice of me, only one man saying, “Is that you, Jim?” But Silver called from the other boat, wanting to know if it was me. Then I began to worry if I had done the right thing.

    The crews rowed to the beach and our boat arrived first. I ran towards the trees. Silver and the rest were a hundred metres behind, and I heard him shouting, “Jim, Jim!” But I took no notice, pushing through trees and bushes, and ran until I could run no longer.

    I was pleased to lose Long John and began to enjoy looking around this strange island. I crossed wet ground and came to a long, open piece of sand, then went on to a place where the trees had branches that were thick and close to the sand.

    Just then I heard distant voices, Silver's among them, and hid behind a tree. Through the leaves, I saw Long John Silver and another of the crew talking together.

    “I'm warning you because I' m your friend, Tom,” Silver was saying.

    “Silver,” said Tom: “You're old and you're honest, or so men say; and you've money, too, which lots of poor seamen haven't. And you're brave. Why let yourself be led away with that kind of scoundrel? I'd rather die than—”

    Suddenly, there was a noise of distant shouting, then a long horrible scream. I had found one honest man here, and that terrible, distant scream told me of another．

    “John!” said Tom: “What was that?”

    “That?” replied Silver. His eyes shone like pieces of broken glass in the sun: “That'll be Alan.”

    “Alan!” cried poor Tom: “An honest and true seaman! John Silver, you've been a friend of mine, but for no longer. You've killed Alan, have you? Then kill me, too, if you can!”

    The brave man turned his back on Silver and began to walk back to the beach. With a shout, Silver threw his crutch through the air. It hit poor Tom between the   shoulders, and he fell to the ground with a cry.

    I fondly remember road trips as a child, sitting in the sunny backseat of my mom's car, daydreaming about other worlds and fantastic adventures. As I've grown older, my daydreams have become increasingly occupied less with fantasy but more with the reality of my past and future. Nearly everyone daydreams about their future and reflects nostalgically (念旧地) or negatively on moments of the past. These moments can provide inspiration, but if you spend too much time daydreaming in this fashion, you may be reducing your success in the present.

    If you've ever planned a vacation, you're familiar with the impatient days tapping at your desk, dreaming of the lazy, relaxing days to come. Unfortunately, sometimes you end up comparing the real vacation to your imagined one, and it doesn't live up to the standard. Reflecting nostalgically on the past can also prevent present enjoyment. It is equally fun to reflect on past achievements or fun events, but it's possible to be so consumed with happy memories that you miss opportunities to create more.

    We've all made mistakes that we're ashamed of; reflecting on them is an important step in correcting those mistakes and becoming a better person. But dwelling（细想）too long on your past can also be negative. If you dwell too long on a past mistake, you can begin to equate（使等同）yourself with your past and feel farther away from the person you want to be. Train your brain to think quickly about the past and future, and take only the information and inspiration that you need in order to be the best person you can without resting on your glory moments or your mistakes.

    If your identity is not dependent on the past or future, every experience is new and every day is a blank page for you to write. A fun mental exercise is to always tell yourself that you're experiencing things for the first time. So take advantage of each moment you're given.

The Alexander technique

    Until earlier this year, I didn't know anything about the Alexander technique—and saw no reason to think I should. One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they'll go away, but I eventually went to the doctor. After examining me, he said, "You actually have bad posture (姿势). Go off and learn the Alexander technique." Three months later I could walk straighter and sit better.

    The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercise-based. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly.

    The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines.

    So who was Alexander and how did he come up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (声音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teacher-training school, which is still successful today.

    So if you're walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.
