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."

Do you have a beautiful dream? I know almost everyone1his/her own dreams. The dreams are veryimportant2 everyone for they can make people3 harder.

I am studying in a school now. My dreams is4 ateacher in Western China. Many children there want to go to school5 they can't. Their families are very poor andthe parents don't have enough6tosend their children to school. But going to school and studying is the only7 tochange their life. Teachers are greatly needed there, so I want to be a teacherto help them. I8 kind to my students and make friends withthem. I will give them love and teach9 how to be a useful person. I think it is agreat10 in the world.

When I was 5 or 6 years old, I was a naughty (调皮) boy. One day, I tried to steal gum from the drugstore when my1 took me shopping. I stood in front of the gum shelf, waiting for the right moment. After about302 , I finally made my move, just as my mum was calling me to3 . As we walked away, a store worker walked up to my mum and told her that I had taken a pack of gum.

My mum was really angry and insisted that it was4 for me to do so. She thought her son was honest, good, and 5 lied or did anything bad. However, the store worker explained that all the workers, from the very beginning, had been watching me for half an hour. It was challenging for them to wait so long before I 6 did it. To prove they were wrong, my mum searched me, checked my pockets, and found7 . The man was surprised, and my mum was proud and even scolded (责备) him.

Seeing the man's face turn red, I felt very sorry. I had to make a choice. As he started to walk away, I 8 my cap, reached inside, and offered the pack of gum to him. I said 9 with all my heart. Both the man and my mother were shocked, for different reasons.

Though I was punished, I felt less guilty because I10 becoming a worse person. Better late than never.

Martin is my youngest son. He likes staying alone and he seldom laughs. As the boy's mother, I was 1 about him. I took him to see the 2 in many hospitals, but it didn't work well. 

Nothing could make him happy except the recycling truck（垃圾回收车） passing by my house. Every afternoon, he raced to the front of the house, waiting 3 the truck. 

When we were late and 4 the truck, Martin would be very disappointed. One day, I stopped the truck and introduced 5 . 

"Nice to meet you, too. I'm Vince, " the driver greeted me in a happy 6 . 

"Your coming is the most exciting moment for my son, "I smiled. 

After knowing our story, he said, "7 you please give me your phone number? Maybe I can send you a message 8 I arrive. "

Then began our friendship with Vince. 

Recently, I said to him, "It's my little boy's birthday tomorrow. Can you do 9 special for him?

The next day, as I was standing by the driveway with Martin, we saw the 10 truck running down the street with a loud beep（嘟嘟声）. Like a superman in a movie, Vince stopped and walked towards us with a box in his hand. 

"Today is your birthday, Martin, and here's a gift. "

He handed the box to my son. Inside, there was a green model truck like his. My son, surprised, looked up 11 and thanked him. 

After chatting for several 12 , he was about to leave for work. I tried to give him some 13 for his help. He kept shaking his head and 14 my money, saying, "Today you, tomorrow me. "

I was deeply moved（感动） by these15 words. And I have been ready to help others whenever I can. You will never know when you're going to be the one that needs help.
