What's that in the sky? Is it a bird? Is it a plane? No, it's Hello Kitty.

That's how Lauren Rojas, 12, from the US thought of her science project. She sent her Hello Kitty doll into the sky early this month. She wanted to find out how altitude(高度) changed air pressure(气压) and temperature, according to New York Daily News.

    Rojas put the doll and a small computer into a rocket model, and then sent it up with a weather balloon(气球). The computer recorded the height, air pressure and temperature. Rojas also put in a video camera to record the trip.

    "It took about two or three weeks to put it all together," said Rojas. "I think people will think it (the video) is really cool."

    The balloon got to 28.5km above the Earth. At that height, the doll could see the blue curves(曲线) of our planet. The air was very thin up there, and soon the balloon broke up (爆炸). The doll fell from the sky and at last it ended up in a tree. It was 76km from the place where it had started its journey.

    July is the time for some students to say goodbye to their mother schools. Every time it comes, I will think of my old deskmate, Xiaowei. She is the most unforgettable classmate in my junior high school life. It has been many years since I graduated, but she is still in my mind clearly.

    Xiaowei was a lovely girl with long black hair. On hot days, her hair was sometimes seen to be tied up. She was always wearing a sweet smile. She was an artistic(文艺范的)girl who showed up before me every day. She loved reading novels and drawing.

    She liked reading different kinds of novels, especially on history. She could finish reading a historical novel as thick as our Chinese textbook at an amazing speed.

    Whenever she had free time, she would take out a drawing note and start drawing cartoons with a pencil. She drew from characters' heads to eyes and to faces, but the characters were always long-haired and wide-eyed. One day I couldn't help asking," Why don't you colour them?" She answered simply, "Because I don't have enough time." She kept her works as a secret and never talked about them with others. When we were told that she had won a prize in the drawing competition in her group, my classmates felt surprised.

    There is a folk song called My Old Deskmate, which is sung widely among people of different ages. It was created because the creator, Gao Xiaosong, had never forgotten his deskmate. Whenever I hear it, I will think of Xiaowei. How are you, my old deskmate?

Two fishermen once had an argument over some juicy oysters (蚝) they had found in the sea. Each man believed that he should 1 them. After a long argument, they both 2 to ask the wise old man's advice to decide who should own the oysters.

Then they went to the old man's house and explained their 3 . The old man asked the first man why he thought the oysters were his.

"Well," replied the man, "We used my 4 to get to the place where the oyster bed was, so the oysters should be mine."

"And you?" asked the old man looking at the second man.

"I should keep all the oysters because I must keep safe among the rocks and 5 the oysters from the ocean bed. I put my life in 6 for them."

When they finished, the old man thought 7 for a moment. "I have made a decision," he said. He divided the oysters into three parts. One for himself, the rest for the two fishermen. The two fishermen were 8 and shouted, "That's not fair!"

The man said, "I help you 9 the problem, so I should get part of the oysters. If you had 10 the oysters before, both of you would have got more."

Terry is 65 years old this year. He is from America. He makes a tree house for his family this year. It's very beautiful.

The tree house is in his back yard with two beds, ten seats and a BBQ. It can hold (容纳) ten people. It is big and brown. Terry spends six months making the tree house. And he gets some help from his good friends.

Terry's friends also like this tree house very much. They often have fun in it. They talk, play games, and listen to music together. "I am happy to share the tree house with my family and my friends." Terry says.

People call him "World's Best Grandpa". Do you know why? Because he makes a cool tree house for his family.

I used to love games. I would spend hours {#blank#}1{#/blank#} on my phone. I used to love going out partying. It was so much fun and I did it every week. But how could I study the next morning after only four{#blank#}2{#/blank#} sleep? It seemed that I{#blank#}3{#/blank#} could't stay focused(注意力集中的) in class.

 At the age of 21, I started to feel {#blank#}4{#/blank#} because my grades were terrible! I feared to have a future without a good job and without enough money. I realized I had nobody to turn to for {#blank#}5{#/blank#} if I didn't get my degree(学位). So I decided to study hard. Finally, I finished my degree with top {#blank#}6{#/blank#} and new-found confidence(自信). Below is some of what I did.

●I went to bed early, no {#blank#}7{#/blank#} than 10:30 p. m. That helped me remember things well.

●I found three favorite study places. They were comfortable and quiet. Going {#blank#}8{#/blank#} different places made me feel fresh.

●{#blank#}9{#/blank#} studying, I turned my phone off and put it away.

●I made my weekly study plans and stuck to(坚持){#blank#}10{#/blank#}. These plans were achievable and gave me confidence to move on.
