One day a farmer went out for a walk with his little son. The farmer wore a pair of wrong shoes. One had thick sole(厚鞋底) but the other didn't. He began to walk and then his feet hurt. When he was just out of the house, he turned to his son and said, “Why is one of my legs longer than the other today?”

      The son looked at his father's legs carefully as he was walking and then laughed, “Oh, no, Daddy. Your legs are all right. You're wearing the wrong shoes.” The farmer was very happy to hear that and said to himself, “What a clever son!” Then he asked his son to go back and got the other pair of shoes for him. The farmer had only two pairs of shoes.

      When the son ran back to the house, he found that the other pair was also a wrong pair. He had to return to his father with nothing in his hands and said, “It's no use changing them, Daddy! The shoes at home are not a pair, either!”

    Jia Zuosheng, 27, used to work as a security guard (保安) at the library of Tsinghua University. But a few months ago, he became a college student in Lishan College in Shandong and he studies math there now. When hearing this news, many people were surprised. On school opening day, many reporters waited outside the school gate to interview him.

"I was born in a poor village in Shandong Province," said Jia. "Our village has never had a college student. Most boys work in town after growing up. I failed the National College Entrance Exam（高考）twice. Then I went to Beijing to find jobs. In the following years, I went on studying by myself while working."

At the end of 2009, Jia found a job as a security guard at the library of Tsinghua University."I cherished (珍惜) the job very much because it gave me a good chance to read books," Jia said."I usually worked at night so I had plenty of time to study in the daytime." When he had problems that he couldn't work out, Jia asked the students at Tsinghua for help. "My dream is to be a college teacher. So I need further education. That's the reason why I took the National College Entrance Exam again," Jia said. "I wish to educate students with my knowledge and love and help them enjoy true, kind and beautiful things."

Jia's mother said Jia has always been independent（独立的）and knows what he wants. But she has other worries. "It's difficult to find such a good job at present as a library guard in Tsinghua University. I'm not sure if this is a right decision." "I will never regret(后悔），"said Jia. "Everyone will have a new start. It's the end, and the beginning."

    One of the most detailed(详细的) descriptions Of a UEO was given by nine-year-old Gaynor in Sunderland in July 1976.

    Gaynor lived in Oakenholt, a village in North Wales. On her way home from school, she saw a silver(银色的) object shaped like a saucer(茶碟) in a field not far from her home.

    The strange craft(飞行物) was about 30 feet long and 9 feet high. It had yellow windows along the side and on the top there was a light flashing in a kind of box. Although Gaynor was very frightened, she did not run away. Instead, she lay quietly in the long grass and watched the door of the strange craft open. She saw two people wearing silver suits come out of the craft. They were carrying some kind of equipment(设备) which they used to examine the ground.  They were short and had large pink eyes, Gaynor reported.

    After about half an hour, the two people went back into the craft. At once there was a loud noise and the UFO took off.

    Although Gaynor told her mother what she had seen, her family decided to keep quiet about it. They did not want people to laugh at their daughter. However, 18 months later, Gaynor told her story to UFO experts. They hypnotized(使进入睡眠状态) Gaynor so that they could be sure she was telling the truth.

    Not only did she repeat her story, but also she was able to draw a picture of what she had seen!

    Birds live in trees. Squirrels(松鼠) live in trees. But do you know that some frogs（青蛙） live in trees, too?

    The tree frogs are hard to find. They can change color. On green leaves, they stay green. On a branch, they keep brown. Some tree frogs can change from green to gold or blue.

    Tree frogs have legs and wide feet. They have sticky pads (肉趾) at the end of their toes（脚趾）. These sticky toe pads keep the tree frogs from falling off.

    Tree frogs have different colors and markings on their skins(皮肤). Their eyes are different, too. Some have green eyes, some gray. Some frogs' eyes are gold, and some are bright red.

    The sounds they made in spring and summer are different, too. One frog makes a sound like a dog barking(狗叫). Another frog makes a loud noise like a snore（打呼噜）. There is even a frog that whistles（吹口哨）!

    As we know, elephants are very cute animals, and many people like them very much. But do you hear of an elephant that can draw?

    Shanti is an elephant and she is good at drawing very much. Somebody has actually paid 2,000 dollars for a painting done by her.

    Shanti has painted 12 paintings so far but now she refuses to paint more. The director of the Prague gallery came up with entirely(完全地) improbably reason why she stops drawing.

    The director said, "She starred as an elephant named Bimbo in a movie. She is a very famous artist in it. Now she is in some sort of depression(抑郁). We will just have to wait for her next wave of creativity."

    Shanti does a good thing. Shanti's paintings bring money which helps elephants in Sri Lanka.
