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!

Ways to Have an Amazing Day

    I am a big believer in the Law of the Harvest: we harvest what we sow. If we plant the seeds of success every day, we will get a successful harvest. {#blank#}1{#/blank#}

Try new things

    So many of life's great experience wait just on the other side of our fears or our comfort zone. When the opportunity to try something new comes up, ask yourself, “Why not?” {#blank#}2{#/blank#} Don't miss out on the great moments that are waiting all around you every day!

Keep learning

    When we were kids it seemed that every day had something new that we had not experienced before. That is why young children will ask their parents “Why?” about a thousand times a week. {#blank#}3{#/blank#} A lifetime of learning leads to a love for life.

Be kind

    It has been said that you can measure a person by how he treats the people who can do nothing for him. How often do you stop to talk to the people you meet with every day？One great way to get more out of your day is to fill it with people you know. {#blank#}4{#/blank#} And take a moment to learn a little about them.

Find a purpose

    {#blank#}5{#/blank#} It may be to run a marathon, write a book, start a business, develop a product, or learn a new hobby or profession.

A. Have one or more big “life goals”.

B. If we don't plant enough, we cannot have a good harvest.

C. We are learning and growing.

D. You have to make the most of every day in life.

E. Provide meaningful services for other people in any situation.

F. Many of the great moments in life are linked to new experiences.

G. The best way to know more people is to be kind to everyone you meet.

    Bill Gates and the president of General Motors have met for lunch, and Gates is going on and on about computer technology. "If automotive technology had kept pace with computer technology over the past few decades, you would now be driving a V-32 instead of a V-8, and it would have a top speed of 10, 000 miles per hour," says Gates. "Or, you could have an economy car that weighs 30 pounds and gets a thousand miles to a gallon of gas. In either case, the sticker price of a new car would be less than $50.Why haven't you guys kept up?"

    The president of GM smiles and says, "Because the federal government won't let us build cars that crash four times a day."

    Why is that funny (or not funny, as the case may be)? Human beings love to laugh, and the average adult laughs 17 times a day. Humans love to laugh so much that there are actually industries built around laughter. Jokes, sitcoms and comedians are all designed to get us laughing, because laughing feels good. For us it seems so natural, but the funny thing is that humans are one of the only species that laughs. Laughter is actually a complex response that involves many of the same skills used in solving problems.

    Laughter is a great thing—that's why we've all heard the saying, "Laughter is the best medicine." There is strong evidence that laughter can actually improve health and help fight disease. In this article, we'll look at laughter—what it is, what happens in our brains when we laugh, what makes us laugh and how it can make us healthier and happier. You'll also learn that there's a tremendous amount that no one understands yet.

    Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

    Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It's this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

    Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

    However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

    As a result, she says, some of the injuries associated with running, such as runner's knee, are uncommon among race walkers. But the sport's strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

Darrion Cockrell,who wasn't much of a student,has been named Missouri's Teacher of the Year—the state's highest honor for educators,becoming the first male since 2015 to capture the state's top award.

Cockrell—the child of "a drug-addicted mother" and a father who was killed when he was four years old—was in and out of the childcare centers and eventually became a gang (帮派) member.In his speech,he shouted out the special people who helped to guide him down the right path when he was going off track.

He thanked his teacher Ken who provided him with life advice while he lived in a boys' group home."He taught me it's OK to be tough,but at the same time,it's OK to be compassionate (富有同情心的),"Cockrell said."He was like a father figure to me."

The teacher—affectionately known as "DC"—also expressed his gratitude to the football coach that adopted him when he was in the 7th grade and helped to change his whole perspective (视角) on life."When I changed the way I looked at things,the things around me started to change,"he said."I had a lot of struggles and a lot of hurdles,and if not for those educators,I would not be here today."

Now,Cockrell hopes to make an impact on the students at Lindbergh Schools' Crestwood Elementary in St.Louis,where he's been teaching physical education since 2015.Among his many accomplishments at the school is his development of the"Crest-Fit"training program for teachers,students and parents.

"Missouri is fortunate to have so many high-quality educators,and Darrion will be a wonderful representative as our state's Teacher of the Year,"Commissioner of Education Margie Vandeven said in a statement."He guides his students towards long-term physical and mental wellness,and the connections he has established will impact Crestwood children for years to come."
