Sharks (鲨鱼) are the most frightening animals in the sea. Sometimes we can see sharks swimming in the sea around Hong Kong. People put nets around some beaches to protect swimmers. When there is a "shark's flag", people must stay on the beach. It will be too late if a shark can swim sixty kilometers an hour to you.

    There are 30 kinds of sharks and 25 kinds of them are dangerous. The whale sharks are very big. They can grow to 18 meters long, but they are not dangerous to people. The jaws (大白鲨) and the tiger sharks are the most dangerous kinds of sharks.

    Do you know all sharks must keep swimming, or they will go down? All sharks can feel everything that happens around them. We must keep calm and don't make any noise when a shark is swimming near you.

    If a shark loses a tooth, a new one will grow out very quickly. So sharks always have many sharp teeth.

Liu Zhihua has become a star at a ski resort（滑雪圣地）in Urumqi, Xinjiang. She is the resort's oldest skier（滑雪者）, aged 88. 

Though she is a skilled skier now, she only took up the sport when she was 72. Before that, like many old people, she spent her days taking care of her grandchildren or watching TV. Encouraged by her children, Liu got on the piste（滑雪道）for the first time in 2007. "The first day was not easy. My arms and legs were sore. But in the next few days, I was able to walk on the skis（滑雪板）. When I was not afraid of falling, I became quite interested in the sport and fell in love with it, "Liu said". I've taken part in a competition twice. I didn't do it for a prize. Finishing the competition without falling is enough for me."

For Liu, skiing is also a way to keep her young and active. Although she is the oldest ski lover at the resort, she thinks she is just as vigorous as younger skiers . Liu skis for about two hours at a time under the protection of her trainer. Although she skis less often than before, she makes up her mind to continue as long as possible. "Doing sports brings me health and happiness," she said. "I don't think age has much to do with my mind. Old or young, I'm always brave and cheerful."

When it rains, we often use an umbrella. When the sun shines brightly in summer, we often use an umbrella. But do you know 1  the umbrella was invented? It is said that the umbrella was made by Lu Ban and his wife over two thousand 2  ago. 

Lu Ban was a famous carpenter(木匠). He 3  went out to work. One morning, when Lu Ban's wife was 4  her way to take the lunch to her husband, it was raining harder and harder, and she had to enter a small 5  nearby. She thought, " How wonderful it will be if the small temple(寺院) can move with me!"

As soon as it stopped 6 , she left the temple and walked on. After a while, it began to rain again. She 7 , but there was no house nearby. She had to lift her 8  to stop the rain from dropping to her head and her clothes. She held the handle(把手) of the basket and walked in the rain. She found the basket looked like a light small moving 9 . 

Suddenly she had an idea, "I'll 10  a small, light, moveable house, then I can take it with me when I am away from my house. "

As soon as she 11  home, she began to make"a moveable house" with bamboo. She worked hard for the whole 12 , but she failed. In the evening, Lu Ban came home. His wife told him her idea. Lu Ban was very 13  to hear that. 

As a carpenter, Lu Ban was very good at his job. He quickly set to work. He and his wife worked on it until midnight. 14 , a small, light, moveable" house" was successfully invented! It was made of wood, bamboo and silk. Lu Ban and his wife 15  it" umbrella", And today there are all kinds of beautiful umbrellas all over the world. 

Michael was an 8-year-old student from America. He became ill and had to spend all day in bed at home. He felt sad and bored because other children could not come near him.

There wasn't much to do, so he just looked out of the window. One day, something strange happened outside the window. It was a panda eating a sandwich. The panda said "Good afternoon" to Michael and then left. Michael was very surprised. He tried to find out what was going on. Suddenly, he saw a monkey playing with a ball outside his window. Michael saw more and more strange animals, and he began to laugh and laugh. Everything seemed to be better and better.

Luckily, Michael's health improved. When he felt better, he went back to school. He told his friend Dave about all the strange things outside his window. While Michael was talking, he saw something in Dave's schoolbag. Michael asked what it was and Dave showed him. Inside the bag he found many clothes that looked like animals. Dave wore them to make Michael feel happy while he was ill!

From that day on, Michael always tried his best to make sure that his friends would never feel sad or bored.
