A friend of mine named Paul received an expensive car from his brother as a Christmas present. On Christmas Eve when Paul came out of his office, a boy was walking around the shinning car. “Is this your car ,Paul ?” he asked. Paul answered ,“Yes, my brother gave it to me for Christmas.” The boy was surprised . “You mean your brother gave it to you and it didn't cost you anything? Well , I wish…” He hesitated.

    Of course, Paul knew what he was going to wish for. He was going to wish he had a brother like that . But what the boy said surprised Paul greatly.

    “I wish,” the boy went on ,“that I could be a brother like that.” Paul looked at the boy in surprise, then he said again,“ Would you like to take a ride in my car ?”

    “Oh yes, I'd love that.”

    After a short ride, the boy with his eyes shining, “Paul, would you mind driving in front of my house?”

    Paul smiled a little. He thought he knew what the boy wanted. He wanted to show his neighbours that he could ride home in a big car. But Paul was wrong again. “Will you stop where those two steps are ?” the boy asked.

    He ran up to the steps. Then in a short while Paul heard him coming back, but he was not coming fast. He was carrying his little crippled* brother. He sat him down on the step and pointed to the car.

    “There it is , Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn't cost him a cent. And some day I'm going to give you one just like it…Then you can see for yourself all the nice things in the Christmas windows that I've been trying to tell you about.”

    Paul got out and lifted the boy to the front seat of his car. The shining—eyed older brother climbed in beside him and the three of them began an unforgettable holiday ride.

The most positive(乐观的) person I have ever seen is my dad! He is so positive that I do not1 hearing a single word from him which is related(相关的) to hopelessness!

Unlike most moms and dads, my dad never says things that make me feel2 He is always there to give me encouragement and help. 3 I do wrong things, he always tells me what's right in a positive way. For example, if I am in4 he often tells me to open the books he bought me. Then he asks me to read the 5 that can help me with the problems I'm facing. After that, we have a6 together. 

Even though I'm not always a good kid, my dad7 shouts or gets angry with me. I know that he's8 a day—a day when I grow up and understand things in my life. 

I can see the reason that he is so positive is because he believes in9 . And he believes that whatever10 , it is under control. So we have nothing to worry about. Be positive!

I like traveling alone. I have been to the Terracotta（兵马俑）, Disneyland and the Bird's Nest（鸟巢）. Attracted(吸引) by the beauty of the Great Wall, I flew there by myself this time.

At the entrance (入口), one short old woman followed me all the time. She wanted me to buy some cards. Finally, I became angry. "Don't you understand the meaning of ‘No'?" I shouted at her and left.

As soon as I walked along the Great Wall, I felt very excited. Then, when I was halfway, I found I was on a very dangerous road, and there were no walls. When the cold wind came, I was afraid. Suddenly, I heard a soft voice behind. Someone told me not to be afraid and she would help me. As I felt a pair of hands trying to keep me safe, I calm down(镇静).

Half an hour later, we arrived at a safer place. Feeling better, I turned around to see who she was. She was the short old woman. I felt humiliated for what I did and gave her a big hug (拥抱).

Through this experience, I learned that we should be kind to others because we never know what situation we'll be in and when we'll need help.

Qian Xuesen was born in Hangzhou, Zhejiang Province on December 11, 1911. In 1929, Qian placed third in the national college entrance examination and got a chance to attend Shanghai Jiao Tong University. There, he received a degree (学位) in mechanical engineering with an emphasis on railroad administration. In 1932, Shanghai was bombed and invaded by Japan. Qian graduated from Shanghai Jiao Tong University in 1934, and the following year he left China for graduate study in the US. 

In an age before computers, Qian's ability to quickly perform complex calculations attracted a group of rocket scientists at California Institute of Technology. Qian joined them and received his PhD degree in both aerospace and mathematics three years later. After he graduated, he became a professor as well as a researcher who studied rockets and missile (导弹) theories. 

In 1949, when the news of the birth of the People's Republic of China came to the United States, Qian Xuesen and his wife decided to return to China. In 1950, when they were ready to return home, they were stopped by US officials and sent to prison. With the help of Chinese government and his friends, he finally returned home. 

When he returned to China in 1955, our country's space research was almost deserted. In 1956, he set up the first research institute of rockets and missiles. And he personally trained the first generation of China's aerospace engineers. He was a pioneer and was honored as "The father of China's Missiles". He is the pride of the Chinese people. He made important contributions to the missile and space programs in China. 

He passed away on October 31, 2009 at the age of 98, but his history still encourages Chinese youth. His devotion to our country was expressed in his saying, "My career is in China, my success is in China and my destination is in China!" When someone said he could make much more money if he stayed in the United States, he laughed and said, "My family name is Qian, but I don't like qian. "
