We all have our own idea of what the perfect smile should look like,whether we show a mouthful of whites or keep our lips closed and turned up at the corners.When we think of the perfect smile,we often picture someone grinning,with all of our teeth showing,but based on new findings,less is actually more.Nathaniel He1wig and his colleagues at the University of Minnesota discovered that a successful,genuine smile actually rests less on showing teeth and more on facial balance and symmetry(对称).
For the study,researchers looked at 3D computer-animated facial models of more than 800 study participants.The computer-animated facial models went through a series of facial transformations,with researchers changing the mouth angle,amount of teeth shown,the degree of the smile.Participants were then asked to rate the models’smiles based on effectiveness,genuineness and pleasantness.
The results of the study found that the most successful smile had a perfect balance of teeth,an ideal mouth angle,and a smile length that extended to what was called the“sweet spot”.Smiles that showed a quick sync(同步)of the left and right side of the face during smiling were also more highly related.
Smiling makes up a good part of our nonverbal(非语言的)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.

Have you ever had one of those days when all you wanted to do was read an emotionally powerful story that would cause you to tears? Most of us tend to be attracted by stories that reach us on multiple levels, including sadness. There are plenty of books that make you cry (and sometimes laugh) and that you can really sink your teeth into. Here are four of them.
1. The Kite Runner
This realistic and moving description of life in Afghanistan accounts for the people who were badly affected by the Taliban. You’ll cry as you get to know the familial relationships and cruelty involved, but you’ll also get a sense of hope as you quickly read through this appealing novel.
2. The Book Thief
Let’s put it this way: Death itself is the narrator. The story is about a young girl named Liesel who has to live with foster parents during World War II. On the way to her new home, her brother dies, setting the gloomy tone for the story. There is hope, however, when Liesel discovers her love for reading and makes a relationship with a young Jewish man she helps hide from the Nazis.
3. The Fault in Our Stars
This is probably the most likely book on the list to make you cry, as it records the experiences of teens who are dying from cancer and living their last days in love. Their lifestyle is tragic and disturbing at the same time, as we watch their health worsen. The real tragedy is the love story between the main characters, who know that their romance is fruitless.
4. A Child Called “It”
Easily one of the saddest stories of abuse in recent decades, A Child Called It is based on the true story of Dave Pelzer, a boy from California who suffered at the hands of his cruel family. The tears will come from both sadness and the inspiration tied to Dave’s fight for survival in an environment where he is believed worthless.
1.What do the four books have in common?
A. They are all about cruel wars.
B. They all probably make you cry.
C. They are all about suffering children.
D. They are all adapted from true stories.
2.Which book is about a young victim whose family treated him cruelly?
A. The Kite Runner B. A Child Called “It”
C. The Fault in Our Stars D. The Book Thief
3.The passage is intended to __________.
A. advise us to buy some books B. inspire us to read more
C. explain why we love reading D. introduce some moving books

Last week, I along with my classmates was asked to attend a lecture, the theme of what was environmental protection. It was given by an university professor. The professor first has us to come up with some problems the earth was faced with. Then he offered some suggestions on what they could do to save our planet in an effectively way. Late after the lecture, I searched the Internet for more informations on this topic. Up to now，I learnt that the problem of air pollution is universal and that we were likely to run out of some natural resources. To make things worse , climate change is becoming a great threat for human beings.
