Once a king got two nice falcons(猎鹰)from his son. He had never seen such beautiful falcons before. He loved them so much and he ordered the best falconer to train them to fly.

    After several months, the king came to see how the training was going on. He found that one falcon had already been able to fly high in the sky, while the other was staying on the branch(树枝) of a tree quietly, just keeping still.

    The king called all his falcons together and ordered them to try every way they could to make the other falcon fly. But none of them succeeded. One day, while the king was taking a walk in the forest, an idea came to his mind. Maybe someone who knew the natural environment well could solve this problem. He sent for a farmer who lived in the forest into his palace to train it at once.

    The next morning, the king saw the other falcon flying above in the sky freely. “It is unbelievable !” shouted the king. How could you make it happen?”

    The farmer replied, “It's very easy. I just cut off the branch where the falcon rested.”

    It is always the same to human beings. We all have “two flying wings” in our hearts as well, but we often seem not to notice them and stay where we just for safety and comfort. We won't realize we can fly so high and freely until the “branch” we are resting on breaks.

    Death of science icon(巨匠)

    In modern history, there has perhaps never been a scientist as well-known as Stephen Hawking. Whether he was educating the world with his knowledge of the universe（宇宙）, or making fun of himself in TV shows like The Simpsons, it's hard to imagine what the world will be like but now Hawking is no longer in it.

    On March 14, the British physicist passed away at his home in Cambridge, England. Since then, many people have expressed their sadness in public, including British computer scientist Tim Berners-Lee, who invented the World Wide Web. “We have lost a great mind and a wonderful spirit,” Berners-Lee wrote.

    Hawking was an icon for many reasons, but he will be best remembered for his work in the field of science. Building on German scientist Albert Einstein's work, Hawking explained his belief that space started with the Big Bang, and will end with Black Holes. This idea kicked off a series of scientific studies including into the origin of the universe itself.

    Besides his work in science, he also managed to overcome many difficulties in his personal life. While studying at Cambridge University, he got a serious illness at the age of 21. His illness left him disabled and he was told he only had a short time to live. However, as we all know, he went on to become one of the greatest minds that the world has ever known.

    Hawking leaves behind a great legacy(遗产). His book A Brief History of Time: From the Big Bang to Black Holes that came out in 1988, became one of the world's best-sellers. He may no longer be with us, but Hawking will continue to inspire the world for generations to come. As he once said himself, “Look up at the stars and not down at your feet.”

    Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn't exist(存在). That changed because of a man named Joseph Merlin. Merlin's work-was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.

    One day Merlin received an invitation to attend a fancy dress ball.  He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.

    Merlin tried different ways to make himself roll. Finally, he decided to put wheels under his shoes. These were the first roller skates. Merlin was very proud of his invention and dreamed of reaching the party on wheels while playing the violin.

    On the night of the party Merlin rolled into the room playing his violin. Everyone was surprised to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot MerIin's grand entrance for a long time!

    Once there was a piece of white and new paper. Children loved playing with it. But one day the paper found itself old and dirty. It was sad.

    It travelled from day to night, from wind to rain. At last someone put it into a machine with other paper. It quickly got sorted(分类). This was the end!

After some time, it woke up. The paper found it was quiet. The paper looked around and realized it was sitting next to some fresh paper. It looked down at itself. It was clean with a very new white coat.

    Long long ago, there was a small village in the mountains, and many people lived there. Mike was one of them. He was a middle-aged man. The people in the village always laughed at him. They liked to show visitors how stupid Mike was. They thought this was an amusing thing to do.

    One day, a visitor came to the village. "Watch this!" a villager said and called to Mike." Come and play a game, Mike." he shouted. Mike walked slowly towards him, with a silly smile on his face. "Look, Mike, "the villager said, "I have got something for you." He showed Mike a $1 coin and a much larger 50￠（美分） coin." Which one would you like？" he asked Mike, holding them both out. Mike immediately took the 50￠coin. The villager laughed." See how stupid he is!" he said," He always does that. How stupid he is!" He walked away, leaving Mike with the visitor.

    The visitor felt sorry for Mike." Mike, listen," he said," Although the 50￠ coin is bigger than the 1 coin, the 1 coin is worth much more. Twice as much." "I know that," Mike said," But the very first time I take the $1 coin, they will stop playing the game. "Mike went away and left the visitor in silence.
