A smile will tell people around you that you are a kind and friendly person. However, many people don’t smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn’t have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others’ teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them.
Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now.

I am a person who can get angry   26 . But after  27 a passage from my English teacher, things have changed  28 . I am studying at a boarding school, so I have to learn  29  how to study well, but how to get on well with others. Some of us are  30  while others are quiet. So it is  31 that people have problems and arguments.

Smiling at others is the easiest way to stop argument. Another way is to think  32 your ideas are right before having an argument. If others’ ideas are really not good, keep and open  33 . Try to forgive（原谅）them. Having a friend is  34 better than having an enemy after all. Also,   35 point out others’ mistakes  36 . If you really want to help them, send a letter  37 . On the other hand, if someone points out your disadvantages, don’t  38 . Just think this is a person who really wants to help you and make friends  39 you. Remember: Forgiving makes life  40 .
