In 50 years of traveling, Colin McCorpuodale has visited every country in the world except three. And everywhere he goes, he sends himself a postcard. He always chooses a postcard with beautiful scenery (风景). Usually he writes just a short message to himself. However, he wrote an interesting story on his latest one, from the Malians Island.

Mr. McCorpuodale lives in London. On one of the walls in his room, you can see a large map of the world. There are hundreds of little red pins (大头针) stuck in it. “These pins mean a lot to me.” says Mr. McCorpuodale, “I follow the rule. I'm allowed to stick one in only if I've been in a place for more than 24 hours.”

Naturally, Mr. McCorpuodale has his favorite places. New Zealand, he describes as “a wonderful country”. About China, he says, “This is the country in the world which is completely different. There is no European influence. ”

Wherever he goes, Mr. McCorpuodale takes with him a photo of his wife, a candle, a shirt with a secret pocket and a pen.

So why does he do it? For the postcards or the travels? Mr. McCorpuodale laughs, “Neither. Only for the meaningful life.”

    "Listen carefully to what I say,"  the time traveler said, "I shall tell you something that you will not agree."

    "Why will we not agree?" I asked.

    "Because the science and mathematics you know are not correct," he said. "You believe there are only three dimensions(三维空间)-length, breadth(宽) and thickness."

    "There is nothing to argue with that, "  the youngest member of our little group said.

    "Exactly!"  the time traveler answered, "But there is also a fourth dimension - time."

    "We all know about time, " another member of the group said. "Time passed."

    "I do not agree,"  the time traveler said, "Length, breadth and thickness do not pass. They stay in the same place in space.  We move about them. I can prove that time is the same. It does not pass. We move in time the same way that we move in breadth, length and thickness."

    None of us believed the time traveler, and we argued with him for many hours.

    "If we could travel back in time,"  the scientist said, "We could do things to change the future."

    "If we could travel forward in time," the doctor(博士) said, "we could do things that change our present."

    The time traveler smiled, "It is clear," he said, "that there is only one way I can show you that I am right. We must do an experiment. Please wait here."

    He left the room and soon returned, carrying what looked like a clock.

    "This is a model of a time machine. It took me two years to make it," the time traveler said. "I want all of you to understand that when I start the machine, it will immediately travel in time and disappear from the present."

    He turned to the youngest of all. "Give me your hand," he said.

    The young man put out his hand. The time traveler took it and placed it on the machine. Immediately, there was a sudden wind, and the little machine disappeared.

    I was certain this was not a trick, but the doctor was not so sure.

    "Are you asking us to believe," he said, "that the machine is now in a different time?"

    "Certainly! In my laboratory, a full-size machine is almost complete. As soon as it is complete, I shall send myself on a journey through time. Would you like to see my machine?"

    "Are you serious about this?" the doctor asked.

    "I have never been more serious about anything," the time traveler said, "Come."

    We followed him to his laboratory. There, we saw the actual machine, not quite complete, but large enough for a man to sit in.

    A lion is tired very much and sleeps on the ground one day . A cat runs after a little mouse . The mouse runs around and comes to the lion .

    It was Saturday again. Grace and Karen disliked Saturdays. That was another thing the twins had in common. They shared the same clothes and tied their hair in the same manner. In fact, it was hard for their classmates and teachers to tell them apart sometimes.

    Unlike their classmates, they had to get up early every Saturday to prepare for their lessons. Grace had to attend the art lesson and Karen had to attend her ballet lesson. "How I wish I could do something different today," said the twins with one voice. All at once, an idea came to Grace and Karen at the same time. "How would you like to be me for a day?" they asked each other. It seemed like a wonderful plan to them. After giving each other a description of their own mends. Grace put on Karen's ballet dress while Karen put Grace's brushes and paints into her bag. Then they left for their classes.

    When the art lesson started, Karen was lost. Unlike Grace, Karen was poor at drawing. When the art lesson finally ended, Karen didn't dare to hand in her work.

    Meanwhile, Grace was struggling in the ballet class as well. As she had no idea about the dance steps, she had to follow her classmates blindly. As a result, she kept knocking into them. Their ballet teacher became impatient with her, "Karen, you should remember the basic steps. You can't rely on copying what others are doing."

    When Karen and Grace got home, they were tired out. They decided that they would never try to be someone else they were not. It seemed that the grass was not always greener on the other side.

    I love movies. Among all of them, I prefer movies that I can get inspiration (激励) from. The Pursuit of Happiness is such a movie. This movie is based on the true story of Chris Gardner, a salesman who managed to build a future for himself and his five-year-old son Christopher. Chris Gardner was having a hard life in San Francisco in 1981. His wife hated to have a poor life so she left home. Gardner and his son were abandoned by her.

    While trying to sell his products, Gardner met Jay Thistle, a successful stockbroker (股票经纪人). His new relationship with Jay helped him earn an internship (实习) in a stock company. Without any pay, Gardner was not able to afford the apartment. He and his son had to sleep on the streets, in homeless shelters and even behind the locked door of a bathroom in the subway station.

    Gardner never let other people in the company know about his bad condition He arrived at the office early and stayed late each day. As an intelligent man, Gardner developed a number of ways to make his work faster and better. And he finally got the job because of his excellent performance.

    With confidence and the love and trust of his son, Chris Gardner got back on his feet and opened, his own company. He reached his American dream at last. And his story has encouraged me to realize my dream.
