Samantha (her husband， John， called her Sam) left the doctor's house looking perfect， satisfied with her appearance.

    The year was 1862. It seemed that the war with the North would never come to an end. Sam's father had left as soon as possible， fighting for their land， for their new government， for the South.

    At last， Samantha reached the house that she and John owned. It was a cold， rainy night， and she was glad to be home. She stepped into the sitting room. John sat in an armchair， reading a book. When he saw her， he put the book down， and stood， reaching his arms out for her. They kissed briefly. He put a hand to her now slightly round belly(肚子) and asked， “What did the doctor say?”

    “He said the baby was fine and that I seemed healthy. Do you have any news?”

    “Surprisingly， yes.” John hesitated for a moment， as if deciding how he would stop what he was about to say， and then unwillingly continued， “I've been required to join the army.”

    Sam screamed， “What?” She was near tears. “But-but we're just starting out.” Her voice shook. “I thought that after two years of begging my mother to let the two of us get married that our life would finally be happy. Isn't there any way you can get out of this?”

    John answered， “I'm afraid not.”

        “Please. Please， John， if you love me， please get out of this. Break a leg or do something.” She began to cry. John comforted her， resting her head on his shoulder.

    “Sam.”

    “What?”

    “Name the child after me； name it John or Joanna. I'll come back as soon as I can. I promise.”

    Sam smiled， knowing that John never broke a promise. She put her hand to her belly， and， unknown to her， the baby was a girl.

    And unknown to both of them， the promise that John had just made would be the only promise he would ever break.

    She is a cute, quiet girl. As a daughter, she has no secrets from her mother, who is very pleased with her. But these days she has become not so open as before. She has a diary that she keeps under lock and key. Her mother cannot help worrying about her: What will I do if she falls in love, which is too early of her age? After all she is reaching the "dangerous time". These thoughts have caused trouble in the mother's mind.

    One weekend the girl came to tell her mother that she was going to the cinema with her schoolmate and would return late. This was the first time her mother agreed, and she couldn't help worrying because her daughter had never been away at night before. The mother waited till nine. She decided to go out to meet her daughter. Just at that time, she heard the noise of a car parking. She went to the window and saw her daughter waving goodbye to a boy. Her heart missed a beat.

    When the girl came in, the mother was watching TV, just like nothing had happened. "Mum, I'm going to bed."

    "All right. Go to sleep early."

    The next morning when the mother went to the daughter's room to do some cleaning, she found her diary left on the bed. After a few minutes' thinking, she at last opened it to the page of the night before. It reads: Mum, it's love that made you ask, but it would show your understanding of me if you hadn't.

    Mr. Jenkins liked all kinds of delicious food. As an important officer, he was often asked to dinner. The shopkeepers tried their best to fawn on(巴结) him. They knew it was good for their business. Now the officer got fatter and fatter. He could hardly go upstairs（楼上） at home and had to sleep downstairs. He often felt tired if he walked or did some housework. He was worried about it and had to go to a doctor. "Stop eating much fat(脂肪) and sugar, Mr. Jenkins," said the doctor, "or it will be worse for your health!" It was difficult for the officer to do it. He didn't do as the doctor said. He found something was wrong with his heart a few months later. Now he thought the doctor was right. And he had to be in hospital. "You must lose weight(减肥), sir," said the doctor, " unless you want to die soon!" "Could you tell me a way to lose weight, please?" "You must do some exercise first." "Which exercise?" "To move your head from side to side when you are invited to dinner!"

    When I was 13 years old, a boy gave me an important gift. It was a smile.

    It was the early autumn of my first year at a junior high school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone.

    Every time I heard the other students talking and laughing, I felt that my heart broke. I couldn't talk to anyone about my problem, and I didn't want my parents to worry about me.

    Then one day, my classmates talked happily with their friends, but I sat at my desk unhappily as usual. At that moment, a boy came into the classroom. I didn't know who he was. He passed me and turned back. He looked at me and without a word, smiled.

    Suddenly(突然), I felt the touch of something bright and friendly. It made me feel happy, lively and warm.

    That smile changed my life. I started to talk with the other students and made friends. Day by day, I became closer to everyone in my class. The boy with the lucky smile has become my best friend now.

    One day, I asked him why he smiled, but he couldn't remember smiling at me! It doesn't matter because all the dark days have gone. Now I believe that the world is what you think it is. If you think you are lonely, you might always be alone. So smile at the world and it will smile back.
