What is the greatest thing in the world? It is a smile. A smile can start a     1    (友谊) and make us feel warm and joyful.

Last year when I     2    (进入) a new school as a middle school student, I had no friends and felt     3    (孤独的).

One day, when running in the playground, I was tripped by a stone and fell onto the ground. I tried to stand up but couldn’t because my knee     4    (受伤) badly. I felt so bad but then a hand came into my sight. As I looked up, I saw a big smile. It was from my new classmate Leo. I grabbed the hand without thinking     5    (两次) and stood up. From then on, Leo and I became good friends.

    6    (然而), even best friends argue sometimes. Leo and I are no exception. Last week after arguing, I went home. That night after calming down I     7    (后悔) my bad temper. But I was embarrassed to talk to Leo. After sending an emoji of a smile to Leo’s mobile phone, I waited and was     8    (担忧的) Leo would never talk to me again. Then I heard the ring of a video chat and when I accepted the chat, I saw a face with a big smile on the screen. I was really     9    (感动的).

You can see how great the power of a smile is. Try to give other people a smile every time and you will       10    (改善) the world!

People in the small town feel     11    (worry). The town     12    (use) to be very quiet. However, these days, something unusual is     13    (happen) in our town. Victor, a teacher, is really nervous. When he     14    (interview) by the town newspaper, he said that he     15    (hear) strange noises outside the window. His wife thought that it     16    (can) be an animal. But Victor and his friends thought it must be teenagers     17    (have) fun. One woman in the area saw something     18    (run) away, but it was dark, so she was not sure. Everyone in the small town is feeling uneasy, and everyone has his or her own ideas. There must be something     19    (visit) the homes in the neighborhood. What is it? People have no idea. Most people hope that this animal or person will simply go away. But the noise-maker is having too much fun     20    (create) fear in the neighborhood.

Mr. Jenkins has several big shops in the city. He’s very rich but he does his best     21    (pay) the persons who work in his shops less. And they all hate him.

Several months ago a young woman borrowed thirty thousand dollars from him. But she couldn’t return the money to him in time. He went to her and made her     22    (give) her ring to him which cost more than fifty thousand dollars. He put it into his wallet and went home happily. But when he got to the bus stop, the bus     23    (leave). He hurried to get on and left his wallet outside. He didn’t find it until he got home. He hurried     24    (make) promise, ＂If someone finds my wallet and returns it to me, I     25    (give) half the money to him.＂

An old woman who     26    (wait) for another bus that day found the wallet. She sent it back to Mr Jenkins. But he changed his mind.

＂There are two rings in my wallet,＂ said Mr. Jenkins, I won’t give half of the money in my wallet to you until you return the other ring to me.＂

＂I     27    (see) only a ring in the wallet,＂ the old woman said and took the man to a judge and told him what     28    (happen) to them. The judge said to Mr. Jenkins, ＂I’m sure you have lost a wallet in which there are two rings and some money. But there is only one ring in this wallet. I     29    (not think) it’s yours. Wait for some days. Perhaps someone will be able to return your wallet to you.＂

Then the judge turned to the old woman and said, ＂Take the wallet home. If the loser doesn’t go to get it back in three days, it     30    (belong) to you.＂

（2017﹒山东威海）My best friend has two first names. One is Heather, and the other is Na-ri. I     31    (never see) her use the name Na-ri. But today, for the first time, she is writing a letter with this name.

She     32    (born) in South Korea and adopted by American parents when she was two years old. One day, she told me about her childhood. When she went out to dinner, some South Korean strangers tried to talk to her in Korean She didn’t understand what they     33    (say), so she just looked at them. She said that she still remembered how they looked at her. Their eyes seemed to say, ＂Poor girl! You are an abandoned child.＂ From that day, Heather tried to keep saying to herself that she was American.

Two days ago, she received a letter from South Korea. The letter     34    (send) to Na-ri. She was so surprised that she couldn’t open the letter. So I did it for her. The letter was written in Korean. I said, ＂Heather, you should ask someone     35    (read) this for you. It was written in Korean.＂ But she was silent.

Yesterday, on the way home, I saw her     36    (cry) on a bench near my house. ＂What is it, honey?＂ I said. She told me that her birth mother had blood cancer, and the only cure for her illness might be Heather’s blood. I asked how she knew this. Heather said she had learned Korean secretly. Crying hard, Heather only repeated, ＂What should I do? What should I do?＂ I really had no answer.

This morning, Heather called me. ＂     37    you be with me when I write a letter to South Korea?＂ I gladly went over to her house. Heather didn’t seem to have slept at all. I hugged her and told her everything would be Okay. Now I     38    (sit) in front of Heather, watching her write a letter. She hasn’t told me what she is writing, but I can guess.   Heather is writing, ＂Na-ri is coming, mother.＂
