    Lots of people stress out about talking in front of the class or getting laughed at if they make a mistake in front of an audience. {#blank#}1{#/blank#}The “stress hormones" that your body produces at times like these can actually help you focus.

    But when worry and stress about performing get to be too much, these hormones give people that “red alert(紧急状态)” feeling—the one that causes you to feel cold or sweaty, or get butterflies in your stomach. {#blank#}2{#/blank#}

    Be prepared. {#blank#}3{#/blank#} Rehearse(排练) as much as you can and practice in front of others at every opportunity. Most of all, think positively. Tell yourself “I'll be OK" or “I can do this" even if you are not 100% sure of it

    Look after yourself. Before big performances it's easy to let taking care of yourself slip as you spend too much time on rehearsals and practice. {#blank#}4{#/blank#} Exercise can also help you feel good, and along with sleep and nutrition, is an excellent way of keeping those stress hormones from getting out of control.

    Find out what the experts do. You can find books, DVDs, and online information about how to give your best when you perform, depending on what type of performance you're preparing for. {#blank#}5{#/blank#} Or ask the cast of your school play or your drama or music teacher how they beat stage fright. And if your parents or grandparents ever performed, they may have their own secrets to share.

    While it's wonderful to share a special trip with friends or family, traveling alone is another experience. {#blank#}1{#/blank#}

1）. Meet new people.

    People who are traveling alone seem more approachable to others. Before you know it, you could be chatting with some interesting folks at a sidewalk cafe or even joining a group of like-minded people on the beach. {#blank#}2{#/blank#}

2）.Do everything you want and nothing you don't want.

    Have you ever been hesitant to do that half-day at the spa you are eager for because you feel bad leaving your travel partner with nothing to do? {#blank#}3{#/blank#} If you want to “waste” the day sitting at an outdoor bar drinking a cocktail instead of sightseeing, you won't have to answer anyone.

3）.{#blank#}4{#/blank#}

    If traveling makes you a good, smart person, then traveling alone makes you better and smarter. Taking a trip by yourself might seem frightening. However, once you take the courage and get over your fears, you'll feel a sense of energy. A successful single vacation can inspire you to try new things in life.

    Have you ever been bored and decided to check social media, only to find out that your best friend is at Disneyland, that one of your classmates is eating delicious pizza at your favorite pizza store, and that one of your soccer teammates is climbing the Eiffel Tower in Paris? Have you ever had that feeling that others are experiencing things and enjoying life more than you are? Oh, man! You're missing out!{#blank#}1{#/blank#}Researchers call that feeling the fear of missing out or FoMO.

    {#blank#}2{#/blank#}It's so easy today to see what your friends are doing from the social media. Unluckily, we only have so much time in the day and only so much money to spend on food or entertainment. It would be impossible for us to enjoy all the same activities we see others take part in on social media.

    Rather than realizing this basic truth, though, we usually let FoMO lead us to compare our lives with those of others on social media. {#blank#}3{#/blank#} Why? We know all the sides of our lives— both good and bad, but all we see on social media are the picture-perfect moments others share.

    {#blank#}4{#/blank#}FoMO makes us check social media more frequently, leading to addiction and a negative cycle that can be hard to break. Researchers have found that social media and FoMO can cause serious negative results, including feeling of depression, loneliness and boredom.

    {#blank#}5{#/blank#}Researchers advise that we stop looking to social media for happiness. Instead, we should focus our attention on our real lives, including the people around us and all the things we're grateful for.

B. At least that's what you might think.

C. This certainly leaves us feeling dissatisfied.

D. So how do we break the cycle and avoid FoMO?

E. Over 75% of young people report feeling FoMO from time to time.

F. As famous Theodore Roosevelt said, "Comparison is the thief of joy".

G. If you let FoMO control you, the only thing you'll really be missing out on is your own life.
