Some young people are worrying about acnes(青春痘) on their faces, and some are worrying about their figures(身材). Do you know 1 on earth(到底,究竟) the secret of beauty is? Think of smile and health, and then you may find the 2 .
Maybe you are not 3 with your big nose, your small 4 or your weight(体重). Don't waste energy and feelings on the way you look . In fact, when you become an 5 and look at pictures of your past time, you'll find how cute you are.
6 is the best way to make you beautiful. When people are happy, they look nice. When people smile or laugh from the7 of their hearts(心脏), they look very beautiful.
Don't worry about your weight too much. Don't 8 food for it. No one lives 9 health. So you need to eat healthy food and do enough exercise.
When you accept(接受) what you have 10 and enjoy them, you will really become pretty “inside and out”.

根据短文理解,选择正确答案。
The size and shape of your ears show your character more than any other part of the face. Other parts of the face change shapes as we get older, but ears do not change their shape. They only change in size.
Reading people's character from their ears is a very old science. In the past people thought that a person's ears with colour was dangerous. They also thought that the shape of the ears showed if a person was musical or not. Today, too many people believe that the size and shape of the ears help you know if a person is musical.
Ears are all different, and each different thing has a meaning. Next time you look at a person, see if his or her ears are large, medium-size, or small. Look at the lobes(耳垂). Do they stick to the face? Ears that are always red mean that a person may get angry easily. Ears that are always cold and nearly white colour mean that a person has a nervous(紧张的) character.
