The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before.

    But just as in face to face communication, there are some rules of behavior that should be followed when on line. {#blank#}1{#/blank#}  Imagine how you'd feel if you were in the other person's shoes. For anything you're about to send: ask yourself, “Would I say this to the person's face?” If the answer is no, rewrite and reread. {#blank#}2{#/blank#}

    If someone in the chat room is rude to you, your instinct(本能) is to fire back in the same manner. But try not to do so. {#blank#}3{#/blank#} If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

    {#blank#}4{#/blank#} Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. {#blank#}5{#/blank#} At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended（冒犯）. It is not polite to ask others personal questions such as their age, sex and marital(婚姻的) status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.

    A lot of kids and adults say they get nervous during social situations. Maybe it's speaking up in class or making a phone call or just trying something new. You might feel butterflies in your stomach, or your heart may beat faster or you get suddenly sweaty. {#blank#}1{#/blank#} And if fear of being embarrassed or making a mistake is getting in your way, there are some things you can try on your own to help.

    {#blank#}2{#/blank#}

    Experts agree that avoiding situations that make us anxious can actually make things worse in the long run. Getting out of something you didn't want to do might make you feel better in the moment, but you will still feel anxious the next time you're asked to do it.

    Push yourself.

    While leaving your comfort zone isn't easy, it can be very good for you. That's because anxiety tends to go away when you start doing the things that make you anxious.{#blank#}3{#/blank#}You might find you have the skills to handle it. And next time you're in that situation you might feel less self-conscious.

    Practice a lot.

    As an experiment, try doing something that makes you nervous.{#blank#}4{#/blank#} Whatever you do, you'll find that it gets easier over time. That's because by practicing the things that make you nervous you are actually improving your ability to easily handle them.

    Relax yourself.

    Instead of trying to relax by watching television or visiting a website, try a deep relaxation practice that has a physical effect on the mind.{#blank#}5{#/blank#}

A. Don't avoid something.

B. Being nervous is uncommon.

    Are you suffering from FOMO—that is, Fear of Missing Out? Research shows that a growing number of young people are with worrying reasons for their sleep and schoolwork.

    {#blank#}1{#/blank#}You aren't able to do your best unless you sleep well. Most experts agree that the optimum（最适宜）number of hours is eight, and this has been accepted as common sense for as long as I can remember. However, I was young once and know most of you get much less sleep than that.

    I read an interesting article in a teachers' magazine recently.{#blank#}2{#/blank#} Worryingly, the results showed that teenagers are facing a new problem. They may go to bed and get up at appropriate times, but a growing number are waking up in the middle of the night, not to use the bathroom or have a snack, but because of FOMO.

    According to the article, the number of students waking up during the night to check social media is growing. Afraid of missing a comment or opportunity to take part in a chat, teenagers are waking at all times of the night, going online and getting involved. {#blank#}3{#/blank#}

    Experts are worried about this growing trend and the report reveals some worrying statistics: 23% of 12 to 15-year-olds wake up nearly every night to use social media. {#blank#}4{#/blank#} One in third of the students are constantly tired and unable to function to their full capacity.

    So I'd like to ask you to be responsible when it comes to social media. Switch off your devices at night. The world won't end and your social media will be waiting to greet you in the morning! {#blank#}5{#/blank#}

A. But things are getting out of hand.

B. I give you my word that you won't have missed anything important.

C. Another 15% wake up at night once a week for the same reason.

D. They did a study of 848 students in Wales.

E. FOMO is the fear that everyone else is having more fun and more excitement than you.

F. All happens when they should be sound asleep.

G. Everybody knows how important it is for students to get a good night's sleep every night.

    It's not easy to talk with teens about their relationship with screens.{#blank#}1{#/blank#}

    Open with a discussion of young children's tech use

    Rather than asking teens to put down iPads, introduce a discussion on babies' tech use. {#blank#}2{#/blank#}When I had my eighth graders read an article about banning iPads for children under two, the class were interested.

    Admit your tech problems

    One of my students wrote that she would like to prevent the whole family from using tech facilities. Clearly, someone in her home was having some tech use problems. {#blank#}3{#/blank#}We can't tell kids to put down their devices if we continue to use them.

Keep a balanced opinion

    We adults wouldn't be able to live in today's society without screens, so we shouldn't expect teenagers to do so either. {#blank#}4{#/blank#}It's improved our lives in many ways. Before we start talking about its challenges, we need to realize its opportunities, too.

    Deal with the topic like you would nutrition (营养)

    If children weren't making good food choices, we would never take their lunches away and make them stay hungry. We would teach them how to eat healthy and help them learn to set new habits: {#blank#}5{#/blank#}Instead of taking their devices away, we should help them keep a balance with technology.

A. The same should go for technology.

B. Technology isn't a bad habit to be got out of.

C. This will invite teens to talk about the subject.

D. Teens need face-to-face communication with adults.

E. One of teens' fears is that we'll take their devices away.

F. So we need to be open about our own tech habits as well.

G. Here are a few ways that will make the discussion easier and more productive.

    World records can be set even if you are over 100 years old. Robert Marchand was born in 1911 in northern France. He enjoys riding a bicycle, and started cycling seriously when he was in his 60s. {#blank#}1{#/blank#}

    On Wednesday, a crowd gathered at the Velodrome National, about 30 kilometers outside of Paris. {#blank#}2{#/blank#} The record for one hour is held by Britain's Bradley Wiggins, a former Tour de France winner.
