When Justin Tong was a child, other kids felt sorry for him. His parents always had him doing lots of housework such as carrying out the rubbish and sending newspapers. But when he grew up, he was better off than his childhood friends and lived a happier and healthier life.

This is the finding of a 40-year study that followed the lives of 456 children in London. It showed that the children who had worked hard in childhood had a richer and a happier future. "Children who worked in the home or community gained competence(能力) and came to feel they were worthwhile members of society," said Daniel Brown, the psychologist(心理学家) who made the discovery. "And because they felt good about themselves, others felt good about them."

Brown's study followed these children in great detail. Interviews were repeated at ages 25, 31 and 47. Under Brown, the researchers compared the children's mental-health scores with their childhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

    Working at any age is important. Childhood activities help a child develop responsibility, independence, confidence and competence — the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this.

    Yet work isn't everything. As Tolstoy once said, "One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work."

Dave is my friend. His family is rich. His parents always give himlots of pocket money(零用钱). But Dave thinks his parents work very hard and it's not easy forthem to make money, so he always tries to save money. He has some good ways todo it.

Dave likes books. He tells me he often buys books online, because they'recheaper. And when he is free, he often goes to bookshops to do some reading. Davehas a bike. He usually goes to school by bike instead of(代替) taking a bus. Sometimes whenit rains or snows, he walks. These two ways help Dave keep healthy and savemoney.

Dave brings a bottle of water to school every day. When others drinkjuice, he enjoys water. He says water is the cheapest and the best drink.

Some students think Dave is mean(吝啬的). But I don't think so. I think he is right.

Have you heard of Charlie and the Chocolate Factory? Do you know who wrote it?

Roald Dahl (1916-1990) was a(n) 1 English writer, seen as another Shakespeare in Children's Books and the one who was best at telling stories in the until he died world. He had written 19 children's books 2 he died at the age of 74. Over 200 million copies of his books have been sold so far. 

At the age of 13, he was sent to a boarding school. There, the boys at the school. There, the boys at the school were sometimes asked to be chocolate testers for a famous chocolate company and this experience later3 him to create the book Charlie and the Chocolate Factory. He also put his 4 experiences into the book. Once he was terribly5 by the headmaster for putting a dead mouse into a teacher's bottle of gobstoppers(大块圆硬糖). This story tells of the importance of being honest and selfless. It also reminds us to 6 our dreams in the face of difficulty and failure. 

Roald Dahl had a great talent for seeing the world through 7 eyes. He liked encouraging children to read. He believed that children should be8 with a book, not bored. Books shouldn't be boring. 9 , they should be funny, exciting and wonderful. And learning to be a10 gives children a wonderful advantage. 

" It's time for Field Day again," thought Chloe as she started the last week of school. Chloe was not looking forward to it." Why does everybody think it a big day?" Chloe asked her 1 ." Well, it should be a fun day and a day to 2 ," said Chloe's mom." I'm not good at any of those games that are played, and I'm afraid the kids are going to 3 me. Maybe I can stay at home and 4 Field Day," said Chloe.

 Mary was Chloe's closest friend, and they walked to school every day." Aren't you 5 Field Day?" Mary asked Chloe." No, I don't care about such a boring day. No one ever picks me for their team 6 I'm not good at those games," answered Chloe7 .

Mary felt bad and she told her mom how unexcited Chloe was and 8 what she could do to cheer her friend up." Maybe you can get in a game that you know Chloe is good at," Mary's mom 9 . Mary thought for a moment and said that she knew Chloe was really good at the game horseshoes. She was also good at the water balloon toss too.

Field Day finally arrived. Mary came by Chloe's house for10 daily walk to school Chloe was very 11 on the way to school. Mary noticed that and said," I hear they are going to have horseshoes this year and also a water balloon game."" Really? I 12 horseshoes, and I am pretty good at catching those water balloons without breaking them." said Chloe.13 , Chloe got excited about going to school and starting Field Day.

The games began, and Chloe had the 14 Field Day ever! Thanks to Mary, Chloe's team won the first place in the water balloon toss and she got a ribbon (绶带) for the second place in horseshoes." What a great day!" Chloe said to Mary. With Mary's15 , Chloe is now looking forward to Field Day next year!

Can 13-year-olds do something to change the world? Cris Kesz Valdez, 13, from the Philippines believes so.

At the age of 7, Valdez set up an organization to give homeless kids things like slippers and toothbrushes. So far he has helped more than 10,000 children improve their lives in his hometown.

Valdez won the 2012 International Children's Peace Prize on September 19, 2012.

"My motto is ‘we can change the world one heart at a time,' " Valdez said at the award ceremony.

In fact, Valdez is a homeless kid himself. He looked for food from trash, lived on the streets and slept in a public cemetery for most of his childhood. His parents didn't care about him and often beat him. Valdez said he felt he was living in "darkness" at that time.

But this "darkness" didn't turn him into a dark person. Valdez got help from community workers. On his first birthday party, at the age of 7, Valdez decided what he wanted most was to help other children who were still living on the streets.

"I didn't have a lot of money, but I had a lot of love to give," Valdez explained.

That day was the birth of the organization, Championing Community Children. Since then, Valdez and his friends visit homeless children and hand out bags with slippers, toys and even candy. They nurse their wounds, teach them about their rights and offer them hope.

"I want children on the streets to get the same chance as I have," he said.
