It seems that the great desire among the young is to be popular. The desire to be popular can force you into looking and acting like everyone else. You can lose yourself in a sea of identical hairstyles and thinking styles.

    I was forced to think about popularity not too long ago in a talk I had with my daughter. Margy had to change schools when my busy work schedule made it necessary for me to move houses. I suppose that，for a girl in her teens，entering a new school is like spending a season alone in the tropical jungles. At least that's how Margy found it at first. However，as the school year drew to a close，one student after another came to her.I told Margy that I would have been more concerned if she had been an instant social success in her new school. Nobody can please everyone. If you try to do so，you will find values as lasting as soap bubbles blown into the air.

    Some teenagers claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up listening to the same record. Their reason for thinking or acting in a certain way is that the crowd is doing it. They have come out of their cocoon into a larger cocoon.

    I know that it has become harder for a young person to stand up against the popularity wave. Our way of life makes a young nonconformist stand out like a Martian. These days there's a great barrier for the young person who wants to find his or her own path. But the barrier is worth climbing over. You may want to listen to classical music instead of going to a party. Well，go to it. Be yourself .Popularity will come with the people who respect you for who you are. That's the only kind of popularity that really counts.

    Do you ever dream about climbing Mount Everest, which is 8,848 meters high? If so, you're not alone. Every year, thousands of people try to climb the world's highest mountains or walk across deserts. Let's take a look at some of the 21st century's greatest adventurers (冒险家).

    Ed Stafford

    Ed Stafford from the UK is the first person to walk along the Amazon River from the mountains of Peru to the mouth of the river in Brazil. There are many dangerous animals in the rainforest, but he was only bitten by ants and mosquitoes. On his trip, Ed had to find fruit and nuts or catch fish each morning. He used a radio to ask the people of the rainforest for food and help. Many people came to meet him and guide him through the rainforest. While he walked, Ed wrote a blog to tell the world about climate change and destruction (破坏) of the rainforest.

    Gerlinde Kaltenbrunner

    Gerinde Kaltenbrunner from Austria is one of the world's greatest climbers and has climbed all the world's mountains over 8,000 metres. It's very difficult to climb in the cold weather and storms, but Gerlinde loves it. Now she spends her time climbing and helping a charity for poor children in Nepal.

    Meagan Mcgrath

    Some adventurers are always looking for a new challenge. Meagan Mcgrath from Canada has climbed mountains, ridden a bike across Canada and run races in the desert to raise money for the disabled.

    Erik Weihenmayer

    Erik Weihenmayer from the United States has climbed mountains and ridden a bike through deserts. Amazingly, Erik is blind and he wants other blind people to have active lives too. He has taken groups of young blind people climbing in Nepal.

    Alvin Irby, a former kindergarten and first-grade teacher, was at a barbershop when he saw one of his former students sitting in the shop with a bored look on his face. That's when Irby realized that by pairing barbershops and books, he might be able to inspire young black boys to read.

    Four years ago, he launched Barbershop Books as a way to not just get books into the hands of young black boys, but to also create community reading spaces in a place where kids go frequently. Since its inception in 2013, the program has created kid-friendly reading spaces in 50 barbershops in 12 states throughout the United States.

    Irby isn't the first person to see the connection between barbers and books and boys. Hair stylist Courtney Holmes, launched a program a few years ago offering free haircuts to kids as long as they read to him while he cuts their hair.

    That's the kind of environment that Irby wants to promote with his program. The reading spaces created by Barbershop Books help to spark an interest in books by showing kids that reading is about more than just spelling and vocabulary skills, it's about making reading a low-stress activity that can help them relax, laugh and have fun.

    “Our belief is that if we can create positive reading experiences early and often for young black boys, then they will choose to read for fun because they will identify as a reader,” Irby noted, adding, “This is really what Barbershop Books is about, getting young black boys to say three words: I'm a reader.”

Irby's idea is catching on, and it will continue to spread thanks in part to the National Book Foundation. Barbershop Books recently won the organization's 2017 Innovations in Reading prize, which is given to Programs that use reading to make a social impact.

Does your school have any problems with discipline? What happens when students step out of line? Here are some examples of bad behaviour:

    Playing truant(missing school without permission from parents).

    Stealing, smoking, hitting, swearing(说脏话), running, kissing.

    Cheating in exams.

    Calling a teacher or another pupil bad names.

    Not doing homework.

    Not listening or not paying attention in lessons.

    Wearing unsuitable clothes.

Here are some of the ways that UK school children can be punished:

Exclusion: a pupil is asked to leave the school and not come back. The pupil has to find a new school or a different method of education.

Suspension: a pupil cannot enter the building or attend lessons until the school has a meeting about their situation. Suspension can last from one to 45 days. The pupil is usually given work to do at home with a special teacher.

Detention: a pupil is asked to stay after school and work for 30—60 minutes before they Can leave.

Lines: a pupil has to write a sentence many times(e.g.100 or more)on a sheet of paper, e, g, “I must not shout in class”.

    Freya MacDonald, a 15-year-old pupil from Scotland, made the news when she refused to accept her school's punishment. Her family says that she was given 11 detentions for trivial things in class and coming into school through a fire door.

Freya says that repeated detentions disrupted her fight to an education under Scottish law and made it difficult for her to learn. She refused to return until the school respected her civil rights. She wants the headmaster and her teachers to sign a letter to promise this. Hundreds of schools in Scotland were told not to use detention as a punishment because of her legal action.

Many UK schools now give parents a home-school contract, explaining their discipline and rules. Parents must sign this document to agree that they accept the school's rules and discipline and that they are responsible for their child's behaviour.

    Slowly but surely  we're moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.

    “5G is one of those signs, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It's pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基础设施) construction. There's lots of data behind that task, which is why we need high speed.

    Augmented reality glasses and virtual headset haven't yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.

    Ericsson stated at February's Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.

    But don't get too excited. There's still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn't concentrated only in big cities.

    When traveling in England, here are some things to keep in mind.

    When taking the underground in England, once on the underground train, stand clear of the closing doors. They can give you a pretty hurtful knock if they hit you. When getting on or off the tube train, make sure you mind the gap(缝隙)! This varies from a few inches to a foot at some of the stations.

    The saying that English food is boring and tasteless isn't true, at least not anymore. You'll find a huge variety of international restaurants, especially in London. Make sure you eat some of the old-fashioned traditional foods in pubs, and wash it down with some local beer!

    Come prepared for any sort of weather ——even if the day starts off well, it's likely that the temperature will change. The best thing to do is layer(分层穿套) your clothes so that you can add or reduce as necessary.

    The British are in general very polite people and will expect at least basic politeness from travelers. Pleases and thanks go a long way! At the same time  they like playing jokes on others. Don't be surprised or offended if you're called darling, dear, dearie, flower, love, chick, chuck, me duck, son, ma'am or any other similar pet name by someone you don't know. It's quite normal.

    England is generally quite safe, but you'll need to be more careful in London and the other large cities, especially at night. Choose an underground train that has plenty of people in it and avoid suburban underground stations at night. There are many night buses you can catch, but try not to do this alone. A licensed cab is often the best choice. Try and leave valuable things in your hotel room, as pickpockets(扒手) do operate in some areas. Be careful of bags especially when in some busy areas.
