Trampolining

    What's more fun than standing still? Jumping up and down on a springy piece of fabric (织物)! This activity is known as trampolining and it's sweeping the nation.

    The idea of trampolining is ancient. Eskimos have been throwing each other in the air for thousands of years. Firemen began using a life net to catch people jumping from buildings in 1887. {#blank#}1{#/blank#}

    A gymnast named George Nissan and his coach Larry Griswold made the first modern trampoline in 1936. {#blank#}2{#/blank#} They named their equipment after the Spanish word trampolín, which means diving board. The men wanted to share their idea with the whole world. In 1942 they began making trampolines to sell to the public.

    Trampolines may be fun, but they can also be dangerous. {#blank#}3{#/blank#} Clubs and gyms use large safety nets or other equipment to make it safer. Most trampoline injuries happen at home. Since trampolines are more affordable than ever, injuries are even more common.

    These injuries happen for many reasons. People may bounce too high and land out of the trampoline or onto the springs. {#blank#}4{#/blank#} Perhaps the worst injuries happen when untrained people try to do flips (快速翻转). Landing on your neck or head can cause injuries or even kill you.

    {#blank#}5{#/blank#} There are many things that you can do to practice safe trampolining. Trampolines have been around for a while now. They have brought a lot of joy to many people. They can be a good source of exercise and activity. They can help people improve their balance and moves. But they can also be deadly. It is important to follow some professional guidance. Be sure that you are practicing safety while having a good time. Happy bouncing!

    Being a fit and healthy person is very important for lots of people today.{#blank#}1{#/blank#}

Thanks to fitness apps and gadgets (小玩意) , people can measure every step they take, what they eat and every calorie they burn.

    Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

    Schedule yearly exams. {#blank#}1{#/blank#}Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#}Two-thirds of Americans spend up to seven hours a day using computers or other digital (数字的)products.   This frequent eye activity increases the risk for eye tiredness. Experts recommend （建议）that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#} As part of a healthy diet, eat more fruits and vegetables each day. Vitamins C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. {#blank#}5{#/blank#} Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

How to stay focused in class

    {#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 is not going to help you stay focused in class and will cause trouble, too.

    Look at the teacher. Your teacher is not just standing up there talking — they're trying to give you an acceptable education. Show the teacher that he or she has your full attention, by looking him or her in the eye.{#blank#}2{#/blank#}

    Take notes. By taking notes, you'll be able to "get into" the lesson.{#blank#}3{#/blank#} Listen for key phrases such as, "This is important," "This is the main idea," etc. This can help you listen more intently (专心地); you'll have something to do and focus on.

    Get involved (参与) in class discussions. This is a wonderful way to become a more focused and successful student. When a teacher asks a question, offer to answer it.{#blank#}4{#/blank#}This shows the teacher that you're listening intently 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're having difficulty with. Chances are, someone else in the class has the same question (and is too afraid to ask!). They'll be relaxed — and so will you.

A. Do your best.

B. Avoid sitting with friends.

C. Don't try to finish your old notes in class.

D. Write down key points as your teacher speaks.

E. If he or she asks for an opinion, share your own.

Does your mood change with the seasons?

    Some people find that when the temperature goes down, so do their spirits. {#blank#}1{#/blank#}They eat more and gain weight. They have trouble sleeping. They can't think clearly.

    Here are some ways you can beat the winter blues:

    Get out in the sun. Some experts say that winter blues happen because we get less sunlight in the winter than we do in other seasons. Some say that the decrease in sunlight can make us feel sad.{#blank#}2{#/blank#}

    Get some exercise. A walk or other exercise will make chemicals called endorphins (内啡肽) flow through your body. Endorphins are natural "feel good" chemicals.

    {#blank#}3{#/blank#}Avoid having too much sugar. If you are eager for sugary foods (like cookies or candy), it may be a sign that you need more protein, like meat, chicken, or fish.

    Avoid holiday stress. Cut back if you have too many things to do. Make sure you have some quiet time to yourself.{#blank#}4{#/blank#}Get some rest. Studies show that most teens need about nine hours of sleep each night. The average teen, though, gets only about six or seven hours of sleep per night.
