There was a little boy who got angry easily. His father gave him a bag of nails(钉子) and told him that every  16  he got angry, to drive a nail into the back wall. The first day the boy had 17  37 nails into the wall. Then he put fewer and fewer nails. He found it was　18   to be not angry than to drive those  19  into the wall. 　Finally the day came when the boy didn't get  20  at all. He told his father about it and the father suggested that the boy now pull out one nail for each day that he was able to be not angry. The days  21  and the young boy was finally able to tell his father that  22  nails were gone. The father took his son by the hand and led him to the  23　. He said, "You have done  24 , my son, but look at the holes in the wall. The wall will  25  be the same. When you say things 　26 , they leave a scar(伤疤) just like this one. You  27  put a knife in a man and draw it out. It won't matter  28  you say I'm sorry, the wound（伤口） is still there. A mental hurt is as bad as a physical one. Friends are a very rare jewel, indeed. They make you  29  and encourage you to succeed. They lend an ear, they share a word of praise, and they always　30　 to open their hearts to us.

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(丑陋的) 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(自信) 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’s teeth are damaged(破坏) 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(牙医) and ask for help. He can help improve your teeth and tell you how to take care of them.

Smiling can help you to feel more confident and make other 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 children should laugh about 300 times a day, while adults should laugh between 7 and 15 times a day. So please smile and laugh now!

　　　 This year the marathon in my hometown took place in the hottest month.My job was to follow behind the runners to see if any of them needed medical care.

　　　 “We should stay behind the last runner, so take it slowly，” I said to the driver, Bob.

　　　 “Let's hope that the last runner is fast！” He laughed.

　　　 Soon the front runners started to disappear, and I saw a woman in a white T?shirt.

　　　 “Bob, look！”

　　　 We knew we were already watching our “last runner”.She was different from the others because of her age.

　　　 “I think she is over 60, too old for any sports match.How can she finish a marathon？” Bob said.

　　　 We watched in silence as she slowly moved forward.We would move forward a little, then stop and wait for her.Then we would move a little bit more.

　　　 As I watched her try to put one foot in front of the other, I found my heart beating for her.I wanted her to stop, but at the same time, I hoped that she wouldn't.

　　　 Soon she was the only runner that we could see.Tears ran down my face.She was so great! For her, it wasn't about beating the other runners or winning something; it was about finishing what she had decided to do.

　　　 Later in my life, when I think things are too difficult, I will think of the woman—the last runner.

　　　 By the way, she did make it to the finish line that day, when the other runners and the cheering crowds had long gone home.
