     Nadia Comaneci，a famous gymnast （体操运动员），was born in Romania in 1961．

    When shewas doing cartwheels （侧手翻%）on the playground at the age of 7，a PE teacher saw her．He told her family that she was very good and advised Nadia to train in the capital of Romania．Although it was a long way from her home，Nadia went because she loved gymnastics （体操）．

    After that，she trained hard and took part in lots of competitions．In 1975，she was named as one of the Athletes of the 20th Century．

    In 1976，Nadia went totheOlympicsinCanada．She was so fantastic in the competition that everyone waited for the score，a high score．But the scoreboard showed1，00!

    Everyone was surprised．There wasn't a sound for a moment．Then a voice came，"Ladies and gentlemen，Nadia Comaneci…10!"

    The audience（观众）cheered very loudly．So what happened？Well，when the scoreboard was built，no one thought a score of 10，00 was possible．The decimal point （小数点）was in the wrong place!In fact，the scoreboard only had three digits（数位） to show scores，such as 9.50 or 9.85 at that time．

    In the 1976 Summer Olympics．Nadia Comaneci scored a perfect 10，which was thought impossible before．From then on，she was looked as a hero．In 1984，she got retired（退休的）．

    It was summer. A duck was sitting on many eggs in her house. Her little ducks were going to come to the world. One little duck after another came out from the eggs. The last baby was big and ugly. His brothers and sisters weren't willing to play with him because he was too ugly. Even his mother hated him too. And the girl who fed them kicked him.

    The poor little duck was so sad that he ran away from home in the winter. On his way, a big dog appeared, but the dog did not come close to him. "Oh, I am so ugly that even the dog won't bite me." the duck said to himself.

A kind farmer took him home when the weather got colder. He stayed there for a whole winter and left when the spring came.

    One day, he met three beautiful white swans (天鹅) when he was swimming in a lake. They swam toward him. He was afraid to make friends with them. But what did he see in the clear water? He was no longer a dark grey ugly duck. He was a beautiful swan himself. How amazing! He never dreamed that he could be so beautiful.

Helen Has Changed

Little Helen lived with her parents and lived a happy life. However, little. Helen got {#blank#}1{#/blank#}(使分开) from her parents this term. Her parents {#blank#}2{#/blank#}(离开) for a big city to make money. Little Helen had to live with her grandparents. She went to a new school in her home town. At first, she felt {#blank#}3{#/blank#}(孤独的;寂寞的). She thought others didn't like her, so when others wanted to make friends with her, she always {#blank#}4{#/blank#}(拒绝). And she never 

{#blank#}5{#/blank#}(解释;说明) the reasons to her classmates. She always kept quiet in the classroom and never {#blank#}6{#/blank#}(提及;谈到)her parents at school.

Miss White, her teacher, noticed that. She {#blank#}7{#/blank#}(介绍) Helen to the classmates. Miss White also encouraged her to {#blank#}8{#/blank#}(参加;加入) in all kinds of after-school activities with them. Miss White gave Helen {#blank#}9{#/blank#} (建议) on how to make friends with others. Day by day, Helen's new classmates make friends with her.

Helen has her {#blank#}10{#/blank#}(最好的) friend Tina and they often help each other. She has completely changed. Now, Helen is a happy girl with a bright smile.

It's a warm Saturday morning. Julia, Mark and Tina are at Simon's house. They are not doing their homework. They are making1 for this afternoon. They2 get together and play sports on Saturday afternoon, but this time, they want to do something3 . They hope to help Mr. White.

Mr. White is an old man in the town. He is seventy years old and he4 alone. His two daughters are both in another town. They' re too busy to look after him. So the four children plan to5 him this afternoon. Julia is going to tell some interesting stories to cheer6 up. Tina, Mark and Simon are going to do some7 for him. It always takes Mr. White a long time to wash his clothes because he is old8 he isn't in good health.

Now, the four good friends are9 . They want to meet Mr. White. They are sure Mr. White will be10 to see them. Maybe it's a big surprise for him.

A young boy had many bad habits. His father was so 1 . He asked an old teacher for help. The teacher took the boy for a walk in the woods. While walking, he suddenly stopped and told the boy to pull out a small plant. 

The boy held the plant and pulled it out 2 . The old man then asked him to pull out a little bigger one. The boy 3 hard and the plant came out, roots (根) and all. "Now pull that one out. said the old man, looking at a small tree. The boy had to use all his strength to pull the 4 out. "Now pull this one out." said the old man, 5 a big tree. The boy held the trunk (树干) and tried to pull it out. But it didn't move at all. "It's 6 " said the boy, out of breath. 

"So they 7 bad habits," said the teacher, "When they are small, it is easy 8 them out, but when they grow bigger, they cannot be pulled out." The old man's words made a great difference to the boy's life. 

What we can learn from the story is: Don't wait 9 bad habits to grow in you. 10 when you have control over them, or they will control you
