微笑需要我們的心態(tài)上的放樂觀，平時多寬容大度一點、用欣賞的姿態(tài)看人。給予他人微笑，會在不知意時候收獲更多！
 
We all have our own idea of what the perfect smile should look like, whether we show a mouthful of pearly whites or keep our lips closed and turned up at the corners just so. New research suggests that there really is a proper way to smile, and it has everything to do with facial expression.
 
我們都有自己的想法，一個完美的笑容應(yīng)該是什么樣子，不管是露出你的大白牙齒，還是嘴角抬起，雙唇上揚(yáng)。一項新的研究表明，正確的微笑，這與面部表情有著密切的關(guān)系。
 
When we think of the perfect smile, we often envision a wide, beaming grin, with all of our teeth showing. However, Nathaniel Helwig and his colleagues at the University of Minnesota discovered that a genuine smile actually rests less on showing teeth and more on facial balance and symmetry .
 
當(dāng)我們想到完美的微笑時，我們往往會想到一個露出所有牙齒的微笑。然而，明尼蘇達(dá)大學(xué)的納撒尼爾·赫爾維希和他的同事發(fā)現(xiàn)，真正的笑容實際上并不是露出幾顆牙，而是更加均衡和對稱的面部表情。
 
Researchers looked at 3D computer-animated facial models of more than 800 participants. The computer-animated facial models underwent a series of facial transformations, with researchers changing the mouth angle, amount of teeth shown, the extent of the smile, and how symmetrical the smile was. Participants were then asked to rate the models’ smiles based on effectiveness, genuineness, pleasantness, and perceived emotional intent.
 
研究人員著眼于800多位參與者的3D電腦動畫面部模型。他們?yōu)檫@些模型做了一系列的面部轉(zhuǎn)換，改變了這些模型嘴角的弧度、露出的牙齒的數(shù)量、微笑的程度以及微笑的對稱度。然后參與者被要求基于有效性、真誠度、愉悅感以及所領(lǐng)會到的情感意圖來為這些模型的微笑評分。
 
The results of the study found that the most successful smile—one that was rated most pleasant, genuine, and effective—had a perfect balance of teeth, an ideal mouth angle, and a smile length that extended to what was dubbed the “sweet spot.” Smiles that demonstrated a quick sync of the left and right side of the face during smiling were also more highly related.
 
研究發(fā)現(xiàn)，最成功的微笑，也就是說，被認(rèn)為是最愉快和最真誠的微笑，最有效的，它顯示了牙齒非常勻稱衡，嘴角弧度完美和微笑的時間也被認(rèn)為是“最好的”。面部兩側(cè)的動作同步也與微笑有關(guān)。
 

As Science Daily notes, smiling makes up a good portion of our nonverbal communication, making it important to have a grin that will draw people to you and also seem sincere. It’s also worth noting that perfect smile could help improve your health too.
 
《每日科學(xué)雜志》指出，微笑在我們的非言語交際中占有很高的比例，微笑會吸引人們來到你身邊，還能使你顯得真誠，它使微笑顯得尤為重要。值得注意的是，一個完美的微笑還有助于改善你的健康。
