There is an English saying:“{#blank#}1{#/blank#}.” Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. {#blank#}2{#/blank#}.

    Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. {#blank#}3{#/blank#}. If laughter exercises the body, it must be beneficial.

    Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐) the pain for the longest time was the group which listened to a funny program. {#blank#}4{#/blank#}.

    {#blank#}5{#/blank#}. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

A. Laughter can make one's life longer.

B. As a result of these discoveries, some doctors in the United States now hold laughter clinics in which they help to improve their patients' condition by encouraging them to laugh.

C. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which reduce both stress and pain.

D. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach and even the feet.

E. Although laughter helps cure the disease, doctors still can not put this theory into clinic practice.

F. Laughter is the best medicine.

G. They have found that laughter really can improve people's health

    Do you know that over ten million American kids go to camp every summer ?{#blank#}1{#/blank#} Back then, hot city summers made people feel bad and even unhealthy for children, so escaping to the country for a few weeks became popular. Today, kids have different reasons for making camp a part of their lives.

To meet new people

    Camp is a great way to make new friends and learn about different places and cultures. Michiko, 13, put it like this, “I loved camp. I met this girl named Manny who lives in New York and she is cool.{#blank#}2{#/blank#}We taught each other words.”

    To challenge (挑战) yourself

    {#blank#}3{#/blank#}Activities like trying new sports, learning new games, or pushing yourself to achieve something need a lot of courage. Arabella, 13, told us, “I went to summer camp and I passed my swimming test! I can hardly swim, so it was a big progress.{#blank#}4{#/blank#}”

    To experience nature

    There's a great big natural world out there, and going to camp helps you learn how beautiful and important it really is.{#blank#}5{#/blank#}Getting out into the woods or mountains can give you a better understanding of the world.

    I have two younger cousins starting their “Third Year of High School.” Though I don't talk to them often, I'm both excited for them and also worried. Are they growing up too fast? Are they eating right? {#blank#}1{#/blank#}

    I throw myself into anxiety. But, today, I stepped back for a moment and came to this realization: my cousins are smarter than my 16-year-old self. If I could go back in time, here's what I would say to myself.

    {#blank#}2{#/blank#} There's a time for everything—don't speed it up. This is especially true for love. Life is much longer than the distance from now until tomorrow.

    Maintain your digital diet. {#blank#}3{#/blank#} Being connected has benefits, but please don't become a victim of the internet.

    Study. You're just starting to define who you want to be and what you want to do. Make sure you study, get the grades, light the midnight oil. {#blank#}4{#/blank#} Study the other things in life—the people who are transforming your community and the simple stuff that makes our world go round. You will discover that each bit of detail will change how you view life.

    Be an upstander, not a bystander. Your biggest childhood regret is not standing up for that kid. The kid is the one who was accused of not fitting in right; the one whose shirt was always stained and whose eyes were dull. Your biggest regret is walking away. And, it doesn't matter if you turned away from the taunting（嘲弄）. It doesn't even matter if you were nice to him when the other kids weren't around. {#blank#}5{#/blank#}

A. Take your time.

B. You'll regret not being more sympathetic, more courageous, more of a leader.

C. Are they dating?

D. Don't be afraid of what will happen.

E. But, don't just study what teachers say you should.

F. Are you worried about your life.

G. You don't need to spend every waking moment on a device.

    {#blank#}3{#/blank#} Conduct research on the destination before you pack your bags and start traveling. Use online information to find how safe the place is. Find whether there will be any festival during that time. No doubt these events are great, but you need to remember that if you do not book hotels in advance, you many fall into trouble in festive seasons.

    Avoid cultural mistakes. Every destination has its own specific set of traditions and customs. Traveling is one of the best ways to learn more about tradition and culture, but take steps not to make cultural mistakes.{#blank#}4{#/blank#}

    Follow these five tips to avoid the common mistakes that make good roommate relationships worse.

    This summer, when earthquakes rocked Southern California on back-to-back days, it was a close-to-home reminder that we may one day experience the "Big One," a quake with the power to kill and destroy. A few people, however, saw something else: a photo opportunity. Tourists poured to a large crack in a highway to see evidence of the damage for themselves and, of course, take a quick selfie.

    {#blank#}1{#/blank#} It feeds so many of the weakest parts of ourselves: our born attraction to images of human faces instead of landscapes or objects, our interest in capturing memories, and yes, our need for social approval. Yet, it is easy to feel uncomfortable with selfies and even laugh at them, especially when they are risky or in bad taste. So why do we take selfies?

    Selfies have become so common that my grandma does them when we get together. {#blank#}2{#/blank#} Instead, selfies are a way for us to connect and communicate, and feel a more personal connection with people all around the world.

    In one example, researchers developed a #ScientistsWhoSelfie campaign studying how scientists posting photos of themselves with their work on social media influenced public opinion of the profession. {#blank#}3{#/blank#} "Those scientists in general were described as warmer, but no less competent," said Paige Jarreau, the lead author on the study.

    While some scientists refused at first, fearing that their colleagues would consider them self-centered or think they take their work less seriously, those concerns disappeared once researchers explained that it could help build public trust. "This is not just me taking a duck-faced (嘟嘟嘴) selfie or trying to look cute on camera," said Dr Jarreau. "This is me being able to better tell the story about my science in a way that helps people trust me."

    {#blank#}4{#/blank#} Dr Jarreau recalled a road trip she made to national parks, where she witnessed so many people taking selfies, she began taking photos of the selfie-takers themselves. "Ask yourself: Why are you posting that picture?" she said. "If there was a platform that didn't enable likes, would you post it?" After all, there are other ways to develop a social connection. You could send the photo to a private group. You could put it in a frame at home. You could be mindful in the moment by not taking it at all. {#blank#}5{#/blank#}

A. But if you do, watch your step.

B. There is no denying the draw of the selfie.

C. With each like, we feel better about ourselves.

D. The thought that selfie is the symbol of self-love is outdated.

E. However, most of us post mechanically, even madly, in our daily lives.

F. After all, people have been making self-portraits for long, in remarkably similar ways.

G. They found that photos with human faces helped improve impressions in a field that is often subject to negative stereotypes.
