　　There’s a lot of joy in living,

　　And it all comes back to you
　　When you add a little sunshine

　　For years scientists have asked themselves a question “Why do we smile?” No other animals smile—only human beings, so does smile help us to survive in any way? The answer seems to be that smiling helps us to relax, reducing tension and preventing illnesses which are caused by stress. On the whole, smiling is really good to us.
　　But some people may still think: if you’re unhappy, it can’t do you any good to smile, can it? Actually, it is not true. Apparently the opposite effects of smiling are just the same whether you feel like smiling or not. Scientists in Californian asked a group of actors to act five different feelings; happiness, sadness, anger, surprise and fear—just using their faces.
　　During they were acting, the change in their heart rate, blood pressure and temperature were written down. Most of the feelings they acted didn’t cause any changes, but when the actors smiled, their heart rate and their blood pressure went down. This happened even though they were only acting! So even if we really feel sad inside, smiling also seems to make us feel better.
　　Besides those, smiling also helps to keep things in perspective. Being interfered by friends or a flat tyre won’t seem quite so bad if you can see the funny side. So if you find yourself in a stressful situation, try to imagine how it must seem to an outsider and let yourself giggle. As a psychologist once wrote: “If people try to show a positive reaction instead of a negative one, this will eventually become part of their personality. If you start to smile, in time you will actually become happier.”
　　So, forget about the unhappy things, face life with a smile, it will make our life more colorful!

　　第二个答案：Today，I read an interesting movie which name is “Akeelah and the spelling bee. ”This movie is based on the traditional game in America called“ spelling bee”. The story is about an 11-year-old girl Akeelah Anderson. Her father died when she was five years old. During her childhood, she lived a poor life with her mother So she can’t afford going to school. Fortunately, she was born to be a good word speller ——she could remember a word instantly. One day, someone told her that she could sign up the “spelling bee”, while her mother didn’t allow her to take part in the competition. A teacher named Larabee want to help her with spelling. At last, after a hard training process and learnt appropriate training methods, she won the championship.
　　I like Akeelah,for she is a sunny girl. She has an optimistic attitude towards life——she went through a lot of difficulties, but she became more confident. Each time she failed , she always said： “It was not a big deal”. I think we should learn from Akeelah. She never complains and she overcame difficulties with her optimistic mind.
　　Nowadays, many people complain that life is bad. For example, if my parents don’t buy my favorite things for me, I will hate them. But to Akeelah, She doesn’t have a father and she only can talk with his photo! In this world, some children are orphans. Now think about, I meet the pain, what! So, I think I should be good to parents, and cherish the time being with them.
　　Many great people also have a lot of difficulties on their road of life. Such as Martin Luther King. He met Kennedy and called for the adoption of new civil rights law- the right to equality for blacks. Martin’s life is like Akeelah’s, they both don’t mind others' strange vision, proceed without hesitation to the dream, and so they can be successful.
　　If you want to be a great person, you need to work hard. Remember the saying: The genius is a special passion! It's not stupid, and you will get a lot. Success has many ways, but the best way is to catch any opportunity to study like a short break between classes when you can read a book or only an article; when you wait a bus on bus station, you can write a poem, when you on the way to school, you can spell some words, at least two, using the money to buy some useful books.it’s better than buying food and toy.....don’t waste time, money and energy to do useless things!
　　And in this story, Larabee sponsored Akeelah a lot. He made her realize their dreams, and let her have a better future. He is not only a good teacher but also making Akeelah feel the warmth from her father. At the same time he made Akeelah happy, too.
　　At last,I think everyone need to be confident,just like Akeelah says: Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. You are the child of God. Your playing small doesn't serve the world. There's nothing enlightened about shrinking so that other people won't feel insecure around you. We are all meant to shine, as children do. We are born to make manifest the glory of God that is within us. It's not just in some of us; it's in all of us. And as we let our light shine, we unconsciously give other people permission to do the same. As we're liberated from our own fear, our presence automatically liberates others.
　　Let’s be a good and a confident person and try to face life with smile!

　　the power of a smile （微笑的力量）
mmm | july 11, 2007 – 11:04 am | so many people underestimate the power and importance of a smile, that simple little facial expression characterized by an upward curving of the corners of the mouth.

a smile has many meanings: pleasure, friendliness, welcome, amusement, and many more; and it is part of a universal body language that doesn’t need any extra interpretation.

plus a smile, with all its simplcity and beauty, can be a very important factor in many aspects of our lives:

- you fall in love with a new country you visit because its people greet you with a welcoming smile everywhere you go; other countries you just don’t like even though they might have more history, nature, entertainment and whatnot because their people don’t seem so friendly or accepting.

- you feel like buying from a certain store when the vendor welcomes you in with a smile, sometimes even if you wouldn’t intially have bought anything; and in other stores, even though they have exactly what you need or better, you decide to walk away because the vendor doesn’t look welcoming at all.

- you want to give a waiter a good tip when he serves you with a smile, even if the food turns out not that good; on the other hand, sometimes you’ll have some of the best food ever, but you won’t feel like giving the waiter a tip, even if you do, because he was grumpy.

more and more examples from our everyday life show how much a simple smile can change everything.

forever engraved in my mind will be the smiling faces of the people of thailand, the friendly pizza delivery boy, the welcoming supermarket vendor, the nice cashier at the bank, …etc.

it is these smiles that keep me wanting to go back, and that keep us all wanting to go back; looking at it from another view, if we break it down using business sense, a smile is one of the most effective means to generate sales and develop customer loyalty.

on top of all that, a smile is a very simple and easy thing to do, so it amazes why no one bothers to do it, it not only makes the person in front of you better, but it also makes you feel better as well, and i’m not making this up, it has been psychologically proven.

personally, i’d like to see more smiling faces in this world; in the airports when i enter a new country, in companies, government agencies, restaurants, hotels, banks, everywhere; and i think it is up to governments to campaign about this, and even make it obligatory in certain important places like airports, hospitals, hotels…etc.

let’s all simply smile.

中文
俗话说：“笑一笑，十年少，愁一愁，白了头。”因而我们面对生活，应有一种积极乐观的态度。
世界上有一种不会凋谢的花朵，那就是微笑；它不分四季，不分南北，只要有人群的地方就会开放。越是纯洁的心灵，越是为其之美。
近期央视“艺术人生”和“新闻调查”栏目相继向全国电视观众介绍了一个人，这个人叫丛飞。丛飞是谁？他是深圳一个普通的歌手，一个没有固定工作没有单位的30出头的男人，但就是这个脸上始终带笑的歌手，在11年的时间里，他参加了400多场义演，捐出了自己辛辛苦苦挣来的300万元，资助了178名贫困学生。如今他是一个病人------一个被诊断为“胃癌晚期”却连医疗费也付不起的病人，但是他始终用微笑面对生活。当然，丛飞还有另外的一些很光荣的头衔：爱心大使、五星级义工、中国百名优秀志愿者。而丛飞在接受采访时则笑着说：“有人说我有3个头衔：傻子、疯子、神经病。”
一个被诊断为“胃癌晚期”却连医疗费也付不起的病人也能用微笑面对生活，为什么我们不能呢？有人说：“活着就是幸福，就是胜利，就是一切。”可我却不这么认为。如果人在生活中，连起码的微笑也没有，那他会幸福吗？如果我们用微笑面对生活，生活也会用微笑面对你。
微笑像阳光，给大地带来温暖；微笑像雨露，滋润着大地。微笑拥有和爱心一样的魔力，可以使饥寒交迫的人感到人间的温暖；可以使走入绝境的人重新看到生活的希望；可以使孤苦无依的人获得心灵的慰藉；还可以使心灵枯萎的人感到情感的滋润。俗话说的好，笑一笑，十年少。永远微笑的人是快乐的，永远微笑的面孔是年轻的！微笑犹如阳光挥洒大地的盎然；清风抚摸树林的温暖；夕阳燃烧天空的炽热；浪花冲刷礁石的激情……
幸福的诠释是微笑；快乐的意义是微笑；温暖的真谛是微笑；挫折的鼓励是微笑；坚强的象征仍然是微笑。阳光雨露，鸟语花香，对于每个人都公平给予； 欢乐喜悦，烦恼忧伤，却属于每一个人私有。 生命总是美丽的，不是苦恼太多，只是我们不懂生活； 不是幸福太少，只是我们不懂把握。 面对生活，不论是失意，还是挫折； 不论是阴云密布，还是困难重重， 我要选择微笑。

　　A smile can change your day - "If you're not using your smile, you're like a man with a million dollars in the bank and no checkbook." Quote "A smile is a curve that sets everything straight." "A smile is the light in your window that tells others that there is a caring, sharing person inside." "Life is short but a smile takes barely a second." "What's the use of worrying? It never was worthwhile, so pack up your troubles in your old kit-bag, and smile, smile, smile." "Sometimes your joy is the source of your smile, but sometimes your smile can be the source of your joy. "Life is like a mirror, if you frown at it, it frowns back; if you smile, it returns the greeting." They say a smile is a frown turned upside down. You can make a choice to be sad or be happy. As for me, I have lots of things that make me smile, and sometimes even laugh out loud. Something that never fails to make me smile is seeing people fall. Don’t think I mean that in a mean way, and don’t deny that you haven’t laughed at this too. I’m not talking about people falling down stairs or off buildings or anything scary like that. Poem Smile because it’s contagious
Smile because it’s healing
Smile because it makes people wonder
Smile because it’s raining
Smile because you’re tickled.
Smile because you’re happy
Smile because you’re idle.

Smile affectionately to show your love
Smile smugly as you’ve done your work.
Smile pleadingly to get what you want
Smile forgivingly to pardon the jerk.

Smile because you’re confused
Smile because you’re lost without a plan.
Smile because you want to
and smile just because you can! Katy Larkin Smile to someone you don't know and it may make their day. Why would one want to smile at someone they don't know especially in this crazy world we live in? Think about the days that you have had when life just seemed so difficult.

Smile, and sometimes can be a life to retain power.
"To retain the life of laughter," tells the story of a place in the true story of the war years, in the story, a huge smile to show her magic.

He visited every day to face the smiling general, the generals began to ignore him, then, he has a little goodwill, and began to talk to him ... ... three months after the date on the blink of an eye later, shot By the time this is a very strange shot: General cite shot on the left hand, right hand to give back to the team that can be a continuation of the war. His turn, he closed his eyes, waiting for death to come, this time, his generals to see, he slowly raised his right hand ... ...
This is the life-saving force, which is hard to imagine the magic! Every day to a general apology to smile, even from its own bottom line back to the original point of death, this not the great power of a smile?

微笑的力量
微笑，有时可以成为挽留生命的力量。
《挽留生命的笑》讲述了一个发生在战争年代的真实故事，在这个故事中，微笑展现了她巨大的魔力。
战争时期，一些德国兵因犯了极大的错误而被将军关了起来，其中有一名士兵特别想活着出去，但这种可能性太渺茫。他得知，他生命中的死亡通牒已下达了——还有三个月就会被枪毙，于是，他对生存不抱任何希望了。两个星期后，他平静了下来。他 每天都会对着来巡视的将军微笑，将军开始对他不理不睬，后来，对他有了一点好感，并开始和他交谈……三个月后的日子一眨眼就过去了，枪毙的时间到了，这是一种非常奇特的枪毙方式：将军举左手就枪毙，举右手就表示可以回到队伍继续打仗。轮到他了，他双眼紧闭，等待死亡的来临，可这时，将军看到是他，他缓缓地举起了右手……
这就是挽救生命的力量，这就是难以想象的神奇！每天给将军一个致歉的微笑，居然能把自己从死亡的底线拉回原点，这难道不是微笑的巨大力量？
如果我们都能微笑着面对每一个人、每一件事，微笑着面对成败荣辱，用微笑面对一切，用真正微笑的心灵感悟美好的生活，那将是无比快乐和幸福的。
嘴角一扬，就能画出一道美丽的弧线，这是多么简单的事情！可是，我们真的能每天为心灵添上微笑吗？没有——考试没考好，干脆破罐破摔；求职不成功，便心情低落；买彩票与一等奖只差一个数字，就捶胸顿足……
严格说来，这些琐事太微不足道了！但有时我们确实为这些事烦恼一整天，从而影响了许多该干的事情。
微笑是一种力量，微笑是一种习惯，习惯于微笑的人不会被小事牵着鼻子走，微笑不仅仅是脸部的表情，还是心灵的状态，微笑应该是发自内心的。故事中的那名士兵如果真的只有生硬的表情，那么，将军一定会认为只是一种讨好而已。
所以微笑是一种积极的心态，你对别人微笑，别人也同样会用微笑回答你。
微笑是心中的一束光，心中有光，则充满希望。
微笑是蕴藏在内心的爱，有魔力的爱。
微笑着面对生活吧！我们会发现，这个世界是那样美好。

How many times a day do you smile? Chances are it might not be enough. Smiling can change your mood, making you feel happy even when you didn't think you could. Think about it—people are always busy, whether they're late to work, shopping around, or running errands. We often forget how easy it is to smile and the significant effect it can have on improving your perspective. If happiness is not enough of an incentive to start smiling, well, for the hell of it, then maybe getting a beach bod is. While smiling may not directly burn calories, it might lead to a good laugh, which could burn anywhere from 10 to 40 calories per day! Science, people! After the jump, find out five more reasons to smile just because. The Frisky: New Study Says More Than Half Of All Couples Are Unhappy

A smile can…

1. ... get you something for free. One day while grocery shopping, I stopped by the Starbucks that recently opened inside the supermarket. I was in the mood for something new, and when I saw that they had a peppermint latte I was sold! I asked the young woman behind the counter for a peppermint latte with skim milk and she proceeded to take out her book of recipes. She was clearly new to Starbucks and did not know how to make the drink, but instead of being impatient, I simply smiled at her and waited. When my drink was ready, she handed it to me with a smile in return and said, "Enjoy it—it's on me." Shocked, I looked and her and asked why. She responded, "You simply smiled and were very nice and you don't see that around that often anymore." I enjoyed my free peppermint latte and kept smiling for the rest of the day.

2. ... simmer down an argument. Whether in person or via text or email, an argument with a boyfriend, girlfriend, loved one, or a co-worker is never easy. Smiling in a time of distress or anger can simply show the other person you are not being defensive. A smiley face can lighten or change the mood of a text message or email, where words are often misconstrued
3. ... attract that cute guy or girl you've been eying. My friends always ask me how I always get the guys that I think are cute. It's simple: I smile. I can't count the amount of times I've been at a bar staring at a hot dude across the room and just by sending over a simple smile, he knows the interest is mutual. This then gives him an incentive to introduce himself. Oftentimes men and women are intimidated or feel as if they will get shut down, so they don't introduce themselves. However, by smiling, you can take away this fear and make the sexy stranger even more interested and at ease. The Frisky: How Not To Flirt

4. ... open all kinds of doors. Smiling can open doors from the working world to your bedroom. This world is as big or as small as we make it—you never know who you're standing next to or who they might know. The truth is, sometimes getting ahead is about connections. Smiling shows a sense of confidence, warmth, and interest. You never know if that person standing next to you in line at the DMV is looking for an employee or a date. Smile at them and you might get lucky enough to find out!

5. ... make someone's day. Sending a smile across the room and receiving one in return always makes you feel good. You never know if someone is upset about something or someone. Maybe by smiling at them you might just brighten their day a little. Smiling is simple to do and may even turn something seemingly innocuous into a life-changing experience
