这周让孩子们观看的TED很简短，但很有用：微笑的暗力量。下面是孩子们的一些分享。

1.      I once made a mistake on saying the title of this talk, and the name that popped out of my mouth ended up as “How to Smile before You Die”. But “the Hidden Power of Smile” is a totally different ted talk in comparison with “How to Live before You Die”. As the word “cortisol” is also mentioned in the talk, “the Hidden Power of Smile” expresses some stuff which is rather similar to my recommendation: “Body language shapes what we are”. I have to say that they have a lot in common, but being in common doesn’t mean being less worthwhile to be watched. The snack-sized talk “the Hidden Power of Smile” mainly focused on a tremendously important and commonly-known nonverbal expression – smiles. People smile before they are even born, and thank to “How to Smile before You Die”, I dare say that more than a dozen people die with smiles as well. Smiling is a global expression and could be part of humanity. Research results mentioned in the talk show that people can benefit longer and more well-being lives through smiling. Smiling, and perhaps some other nonverbal expressions, is also a possible way of mood-changing, which is also mentioned in my recommendation. The ted talk lasts less than 8 minutes, and the presenter’s presentation techniques are well done. We can learn a lot from him – both his idea and his presentation (not the accent part).

2.      I already know the hidden power of smiling, for I have already walked into a video about this. I have to say, I smile a lot of times, it is very hard to find me not smiling unless I’m in an extremely bad mood. One of my friends once asked me, “You like smiling don’t you, Jane?” I nodded in reply. Before I watched the two videos, I always thought that smiling makes your mood better, and I see that I am right. For example, today, one of my classmates drove me mad so I kept smiling like I used to, after half an hour, I was cheered up by just a smile. So my motto is: Keep smiling.

3.      Ron Gutman, who is the founder and CEO of HealthTap, free mobile and online apps for health info, talked about the hidden power of smile. He told us a lot of examples of the benefits of laughing, and made a lot of fun. I am a person who likes to smile and I have made my classmate who sits next to me like to smile, too. And he always says that it’s so bad I made him so love to smile! So I have the same feeling with the speaker. And I really feel that smile can give us power as 2000 bars of chocolate.

4.      Today, I watched a TED talk called The Hidden Power of Smiling. Before watching this talk, I’ve known that it is important to keep smiling. And this talk strengthens that idea. Smiling is a symbol of happiness. And happy feelings really affect our life. For example, we all know that feeling happy and smiling can let people feel more powerful, make people healthier, even cure some people’s illness. In addition, smiling can make the other people feel happy. When people are communicating, smile often means friendly. If someone fails and is very upset, give him (her) a warm smile and help him (her), he (her) can feel more happy and courageous, and may work harder to get success. So as a summary, we need to ‘Smile at the world, and it will smile back.’

5.      The speaker cited several researches to support his view that smiling will lead us to a better life, and, moreover, that we can predict an individual’s life by measuring the breadth of his/her smile. I enjoyed his speech for its fun content and the enthusiastic way he spoke. And there were two studies he mentioned that impressed me a lot. One is based on Darwin’s theory that smiling is not merely a result of feeling good, it can make us feel better as well by modifying the neural processing of emotional content in our brain. This idea supports the old saying that smiling a lot will make everything become better. Another study surprised me, too: that we need to experience a smile physically to better judge whether others’ smiles are fake or real.

6.      In the talk, Ron Gutman reviews studies about smiling and reveals some surprising results. Smiling originates from the natural instinct of humanity. We are actually born smiling. The power of smiling can go beyond the language barrier and is able to be commonly comprehended by all members of our species------even the hunter-gatherer tribes in Papua New Guinea! In everyday life, smiling is commonly considered as a way of expressing satisfaction and happiness. But some researches nowadays indicated that smiling can assist a lot in improving our way of life. English researchers investigated that the positive influence to our brain delivered by a smile One smile can generate the same brain stimulation as eating 2000 bars of chocolate or getting 16000 pounds. Smiling can decrease the level of dopamine, cortisol, and adrenaline, which act as accelerants of tension. Furthermore, Person who smiles more can live longer than the ones who smile less, which means that the frequency of your smiling can be a predictor of how long you'll live.  As a result, a simple smile can have a measurable effect on your overall well-being. So, in order to enhance your life quality, please smile more.

7.      This is quite a short talk. The speaker uses 8 minutes to tell the audiences one thing—smile more. Smile, is not only the result of feeling good. It can also change our feelings. He did many observations to show his opinion. As a result, the people who smiled a lot lived a longer life. And he said a smile is happier than 200 bars of chocolate in our brain. It may even be more than 250000 cash. That is really not bad. Just a smile, we can feel better, live longer, looks more friendly and so on. So smile more.
