A boy and a girl were playing together. The boy had a lot of small glass 1. The girl had some candies with her. The boy told the girl that he would2her all his balls in exchange for (交换) her candies. The girl thought that was a good3.

    But the boy didn't give4of his balls to the girl. He kept the biggest and the5ball in his pocket and gave the others to the girl. 6the girl gave him all her candies.

    That night, the girl had a 7sleep, but the boy didn't sleep well. He kept thinking whether the girl had 8some candies from him.

    You think in the way you do things. If you don' t give your hundred percent(百分之百) in a relationship, you'll 9 keep thinking if the other person has given his or her hundred percent. This is true for any relationship.

    Give your hundred percent to everything you do and you'll find that you can always10a lot of happiness.

    At the age of 12, most of the kids like to watch TV or1online games. But the 12-year-old Jaysea is2teaching yoga. She finished 200 hours teacher training and is the youngest yoga3now.

    She teaches kids and teenagers yoga. “I want to do this for a long time4I love so much,” says Jaysea, the girl5long blonde hair and long legs. She seems quieter 6more serious than most other kids.

    She7a twin brother and a 15-year-old brother. Their parents, Rick and Julie said,

    "They only go to school three days a8. We tell them to think about9they want to do and they have10days to do it. And when they finish high school, they will get their favorite11."

    Her father says she still12her best at school. "She finishes all her homework and she 13 wants to miss a class."

    School doesn't14before 9:45 a.m. or 10:30 a.m., so Jaysea has enough time to do practice every15at home for an hour.

    Kierman was born in Sydney, Australia, and grew up near the sea. For more than 40 years, he raced in international sailing competitions.

    In 1987, Kierman was competing in an around-the world race when he began to 1 the huge amount of rubbish in the world's oceans.  When he returned to Australia, he 2 to do something about it.

    He organized a community 3 called "Clean Up Sydney Harbour". On Sunday, January 8, 1989, more than 40,000 volunteers came out to 4away rubbish. The next year, Kierman made the clean-up a national event. It was a huge 5 Across Australia, about 300,000 people spent the day improving their local 6.

    Since then, "Clean Up Australia" has got 7every year. In 2002, for example, 800,000 people cleaned up almost 15,000 tons of rubbish from Australia's beaches, parks and streets.

    Kierman was 8 with the success of his project. In 2003, he started an even bigger program. With the9 of the United Nations Environment Program, he introduced "Clean Up the World", an international program that supports communities around the world in cleaning up and protecting the environment. "Clean Up the World" has grown 10 and his wonderful idea has now spread from one city to the whole world.

I used to be the shortest in my class. I had no friends and always felt 1 . On my 12th birthday, I made a 2 that I could grow up quickly.

Last summer vacation, I was so worried about my 3 that I didn't want to go to summer camp. But my mom said,"You will learn something 4 you get there."And I had to say yes.

5 Monday, my teacher Maggie asked all of us to climb a wall. When I saw the wall, I was so 6 . It might be ten meters high! I thought I could 7 climb that huge wall successfully.

After the other campers finished, I told Maggie I wanted to 8 climbing.

"Amy, when you meet 9 , just believe in yourself and never give up."said Maggie. Hearing this, I felt a little upset. Suddenly, I had a good 10 . I pretended (假装) to 11 my knee and couldn't move.

"How's the knee? Are you OK?"Maggie asked. She was so 12 that I didn't want to cheat(欺骗) her again.

I said sorry to her. Maggie smiled, and showed me 13 she climbed the wall.The other campers were also cheering for me.

I tried my best and kept trying. And finally something 14 happened—I made it!

From this experience, I've learned a lot. Anything is possible if you 15 in yourself.

I was lonely when I was in high school because I went to a new school far away from my home. In the beginning, some naughty students often laughed at me because of my poor English, so I always tried to avoid them.

Soon I went to university. I was a poor student and I only had $20 for two weeks. I had to hide the truth carefully because I was afraid to be laughed at again. I ate little every day. One day, Joe, a classmate of mine, invited me to help him cook and then shared the completed dishes with him. Since I was not familiar（熟悉）with him, I refused him at first. But after some consideration, I decided to go. I used to cook at home, and I thought I could do it, but I was still full of worry. If he didn't like my cooking, what should I do? Later, it turned out to be a success. Then Joe wished me to make it a daily routine. It went like this. He did the shopping and I did the cooking. And then I stayed to have dinner with him.

It was not until graduation that I knew the whole story. Joe discovered my situation two years ago. In order not to hurt my pride, he came up with this idea just to make it much easier for me. When I cooked the last meal for him, I ordered a big cake and said to him with tears, "My dear friend, you and your help really brighten my college life. I'll never forget that."

There are some very good inventions which, for one reason or another, don't become popular. These inventions should be better known, even though I think that some of them are crazy. Let's have a look at some of these inventions and see if you agree that they should be more successful. 

The Australians had a great idea to stop people from drinking and driving. The idea was that if a driver wanted to start the car, she or he would have to blow into a bag first. If there was too much alcohol(酒精) in their breath, the car wouldn't start. It sounded like a great idea to me, but people said that they might need to drive the car in an emergency even if they had drunk too much alcohol. Another idea I liked was an invention by a scientist who thought his children watched too much TV. He linked the TV to an exercise bike so that the electricity to power the TV was generated(产出) by the bike. If the children wanted to watch a lot of TV, they had to pedal(踩踏板) very hard. I found another invention on the Internet which was intended (倾向于) to encourage good habits. Believe it or not, this invention was an ashtray(烟灰缸) which spoke to you when you lit a cigarette! The "voice" of the ashtray was activated (启动) by the heat from the cigarette and reminded you how dangerous it is to smoke. 

One of the strangest inventions I have come across is a bicycle which can cross rivers! The idea was that when you came to a river, you could inflate a huge plastic ball all around the bike. You would then get into the ball which would float on the river while you pedaled the bike inside the ball! Why not use a bridge instead? A friend of mine at school once bought a strange pair of football shoes. On the bottom of the shoes there was a rotating pad of studs (转动钉垫). The idea was that you would change direction more quickly if the studs rotated with you. The problem was that every time you stopped you changed direction whether you wanted to or not! I think he wore those shoes twice! One thing I would like is a baseball cap with a built-in radio so you can listen to sport all day with your hands free. While we are on the subject of sport, the Americans invented a kind of robot for sports fans. If you were watching your team on TV on your own, you could press a button and the robot would do "high fives" with you! Fantastic! I wonder if you have any good ideas for inventions like these.
