Great inventors like Thomas Edison have impacted people's lives with their inventions. While their contributions are certainly valuable, other amazing inventions were actually created by children!

    The trampoline

    Trampolines are great for both fun and exercise, but they are a fairly recent invention. In the 1930s, George Nissen was inspired to make a bouncy "net" after seeing a circus performance. He thought it more entertaining for performers to continue bouncing instead of landing in a net. So, at the age of 16, he made it by stretching thick cloth in a metal frame.

    The Popsicle

    Cold weather led to the creation of a delicious invention-the Popsicle. Frank Epperson was just 11 years old when he accidentally created his first Popsicle. He was making himself a soda drink and left his glass outside overnight. When he found it in the morning, it had frozen solid with the stir(搅拌)stick still in the glass. And the first Popsicle was born.

Braille

    Three-year-old Louis Braille experienced a serious eye injury that blinded him in both eyes. He struggled to read by moving his fingers across raised letters, but that proved very difficult. At the age of twelve, Louis learned about a communication system where messages could be read silently with fingertips. He changed it and created Braille. It's now used around the world!

BEACON

    When Hannah Herbst was just 14 years old, she was named America's Top Young Scientist for inventing a device called BEACON. After receiving a letter from her Ethiopian pen pal, Hannah was inspired to create a device that could convert the energy from ocean waves into electricity which she hopes will help people without easy access to electricity.

    When Sarah Wishnia received an iPad from her daughter, "It was like Greek to me." Max Rosenblum showed her how to socialize on Facebook and shop on Amazon with her new device. With Max's help, Elena learned to give orders to Sin, Mike familiarized himself with Waze and Honey began searching for information about movies, restaurants and books on her smartphone. Max is 16, a rising junior in Davie. His students are residents of Coral Gables, fascinated by technology and eager to learn about this brave new frontier. Max began offering his tech coaching for seniors a year ago, after he helped his grandmother with her iPhone and iPad. He taught her how to text and use Facebook. He also downloaded a Scrabble app for her to play. "She loved it," he said, not without a trace of pride.

    That experience inspired him and his parents, Adam and Heather. They reached out to a connection at Coral Gables and launched a website, techmaxed.com. He also recruited (招募) other teens to teach the one-on-one lessons in Coral Gables. These youths go to the retirement communities at least once a month. Though teaching a class might appear to be more expedient, soon Max found out that group sessions simply didn't work. "People are at different levels, and it was hard to teach that way," he said. "It's much better to give them individual help." "Most people come more than once," he added. "I have my regulars."

    "First he showed me how to get my email on the phone," Rosen, 88, said, "and then he wrote up a short step-by-step guide for me so I could remember." Max admits that teaching older adults takes time, but he figures he's also paying it forward.

    "Maybe when I'm 87 and there's new technology," he said, "somebody will teach me, too."

The Chinese Doctor Who Beat the Plague (瘟疫)

    In the winter of 1910, Dr. Wu Lien-teh stepped off a train in the northern Chinese city of Harbin. He was there to solve a medical mystery, at great personal risk. Over the past few months, an unknown disease had swept along the railways of northeast China, killing 99.9% of its victims. The Qing Imperial court had sent the Cambridge-educated Dr. Wu north to stop the epidemic (流行病).

    When Dr. Wu arrived in Harbin on Christmas Eve, 1910, he carried little in the way of medical instruments and had only one assistant. One of Wu's first acts upon arrival was to set up special quarantine (隔离) units and to order lockdowns to stop infected persons from traveling and spreading the disease. He had teams check households for possible cases, and even managed to convince authorities to completely close the railways in the early weeks of 1911. Of particular concern was the upcoming Chinese New Year holiday, which had become a great annual migration of people traveling across the country to see their families.

    Thanks to Dr. Wu's efforts, the number of plague victims began to die down, and by March 1, 1911 the epidemic was fully contained. The pneumonic (肺炎的) plague outbreak of 1910-1911 lasted nearly four months, affected five provinces and six major cities, and accounted for over 60,000 deaths. It is clear that without the brave and decisive actions taken by Dr. Wu it could have been much worse. Had the epidemic gone unchecked, allowing holiday rail passengers to spread the disease to the rest of China could have meant a catastrophic loss of life and possibly a global health crisis.

    In April 1911, Dr. Wu chaired an International Plague Conference in Shenyang, attended by scientists from 11 countries including the United States, Great Britain, Russia, Japan and France. They praised Dr. Wu for his handling of the 1910-1911 outbreak. For a time, Dr. Wu was the world's most famous plague fighter, a title he defended in a malaria epidemic in China in 1919, and a return of plague in 1921.

    I sent a message to my sister at 12: 30 p. m. during my lunch to ask her about my father's progress. He was having his second knee surgery and my expectations were the same as the previous successful surgery. My brother picked me up from school and we headed for the hospital.

    When we arrived at the hospital, my first question was "How is he doing?" My father was connected to a breathing machine and his face was very swollen. I tried my best not to cry because I was supposed to interpret for him what was happening as the nurses did not speak Spanish. I had never seen my father this way. He looked so fragile and different from the strong man I knew. I asked him how he was doing and he said he was fine. I returned to the lobby and I was in a state where I realized that my hero, best friend, and love of my life was in a dangerous state and at this point anything could happen.

    I recalled on when I was a child. "I'm going to the store" were always his words, and that was without a doubt my cue to follow him. We would walk to the car, and sometimes if I was lucky, I got away with sitting in the front seat. We would arrive at the store and he always said "Get whatever you want and something for Ana"; Ana is my sister. My dad and I were best friends, he never showed preference with his children, but I just always happened to follow him. It was okay for me to cry when I wanted something because I was his youngest girl, he couldn't say no to me.

    All along my father had dedicated his life to giving us the best. Growing up does not necessarily mean that one must distance from our parents because it is childish; it is a time to take action and embrace the feelings because it is the right thing to do. Life presents us signals to acknowledge and value what is the most important in life.

    Can't Resist Junk Food? Study Suggests You Try This Simple Trick

    You're tired and hungry. Then you catch a whiff of something delicious, probably fried and almost certainly fattening. It is fried chicken!A new research says that exposing to the smell of junk food for at least two minutes can actually help you make healthier food choices.

    Let's take a closer look at this process. Have you ever noticed that whatever appetizing treat catches your nose's attention tends to be most appealing just after you first smell it? What will happen if you're standing in line after a couple of minutes?And recent science says that this is actually the right moment to walk away.

    The results of a series of experiments, including field studies at a supermarket and at a middle school cafeteria, show that extended exposure (of more than two minutes) to junk food smell (e. g., cookie smell) leads to lower purchases of unhealthy foods compared with healthy smell (e.g., strawberry smell)That is why long exposure to junk food smell can be as satisfactory as actually having it in your mouth, which in turn decreases the desire for consumption of junk food.

    When the exposure to smell of healthy food were examined, food choices were not profoundly influenced. The reason for this is that healthy food are not connected with reward in our brain and therefore have little influence on what we desire.

    So next time you're feeling you don't have the will power to resist that French fries, it might be as simple as sitting there and smelling all that sweetness for just a minute or two.

A. But wait a minute before you order.

B. It's a response that has been researched.

C. Get the satisfaction with none of the calories.

D. It isn't quite as irresistible as it was just moments ago.

E. However, it's not the same case with smell of healthy food.

F. It's the same as actually eating it because your desire to eat it is satisfied.

G. The brain doesn't necessarily distinguish between a pleasurable smell or taste.

    When people find out my son Sam is a competitive mathlete, they usually ask if my husband and I are "math persons". The answer is definitely not.

    Ninth grade was1for Sam. To prepare for a competition, he took2practice tests, which were sometimes as3as three hours. In the end, he didn't do as well as he'd hoped and was4by a math camp he'd applied to.

    He wandered into my office one day last spring, murmuring.

    "I just feel like the whole year's been a5."

    I get it. How many days-weeks, months-have I "wasted" writing the6scene over and over again? Writing a novel sometimes feels like two steps forward, one step back.7whenever I feel like that, I try to8myself that no matter what happens with my book, I've9the time I've spent working on it. The delight I find in writing is10for me.

    "Nothing's ever wasted. You may not have gotten the11you wanted, but as you try to solve the12problems, you are making progress with each effort you make."

    He shrugged (耸肩)."I feel like everyone else did better than me."

    Sam was talking about the13boards, where math kids come together to share resources and, more often than not,14their wins.

    "I know it feels that way, but it isn't true. You know people15their successes far more than their16," I said, as much to myself as to Sam.

    Just like Sam, I can't control the17, only my input. To devote time to something with no18of its success is risky and19. But, then again, so is everything.

    And you don't need to be a(n)20person to know that.

    As to garlic and raw onion, you might want to avoid their after-effects, but many of these(positive) unfriendly foods are good for you. In fact, although the smell on your breath may be bad, the effects are immediate and can last for hours. The reason is that garlic and onions contain something that is very smelly and can contributebad breath. As the foods are digested, the special oils they contain     (absorb) into your bloodstream and you breathe(they) out until the foods arc removed from your body. Despite all this, you should cat them. Those who add garlic and onions to food need(little) salt than those who do not. So it's66 healthier alternative, says Rebecca Valle, a dietitian at Alfred Hospital in Melbourne, Australia. "Garlic and onions can also protect against(disease) and promote good health," she says. So how do you enjoy them without(offend) everyone around you? Eating less of the garlic and onion and drinking plenty of water works. Drinking milk also helps reduce the thingscause garlic breath. Chewing gum, sucking on a mint or sipping peppermint tea will also help. But remember(see) your doctor if your bad breath continues.

    After graduating from high school, I'm going to be computer programmer, which I think is on great demand in the modem world. Moreover, my parents would like me to study medicine. They believe here are two reasons for being a doctor. One is that doctors usually deal with patients in person, which mean they are able to help people in need direct. The other is that doctors are so important that it is almost impossible for it to lose jobs. Up to now I have chatted with my parents for three time. To my disappointment, I was failed to persuade them. Now I am confusing about how to solve the problem.
