以微笑为主题写一篇英语作文。求学霸！！

The easiest way to a great smile is to be happy. You can be happy all the time, but not everybody is; when you are not, you can think happy thoughts instead. Think about something or someone that you care about, or think about a joke that you just find hilarious. Remarkably, when you're feeling down, smiling can help cheer you up, even if you have to coax a smile out at first.
When we think of smiling, we think of the mouth, but the eyes may actually be more essential to a warm, genuine smile. Smiling with your eyes is difficult to describe--in general your cheekbones lift slightly and your eyebrows dip a little--but when you see it, you know it: it's that look of your eyes "lighting up" or "twinkling." To get a feel for how to make your eyes smile, get in front of a mirror and practice smiling, but concentrate only on your eyes. You may find it helpful to cover the lower part of your face with a piece of paper. Play around with it a bit, and you'll find that you can make your mouth smile when your eyes aren't smiling, and you can also smile only with your eyes. When your eyes do smile, remember how it feels, which muscles are working and how. With practice, you'll be able to smile with your eyes at will.
