What will you do when you have something difficult to do? I used to ask my mother for help. But she always said, "Do it yourself, dear." or "God helps those who help themselves , girl." I was not glad at all. I thought she was the laziest mother in the world.

For example, one day, I decided to invite some friends to my home. My bedroom was not in order. Books were everywhere. And I didn't make the bed. I asked my mother to help me to clean it, but she still said, "Do it yourself, girl."

Because of my "lazy mother", I have to wash my clothes and clean my room. I have to help my parents do some housework. I even have to go to the dentist by myself. It is really hard for me to do everything well, but I have learned a lot.

    As time goes by, I come to understand my mother. She makes me clever and active! What a great mother!

    Mick Polly has a toy store. He lives with his daughter Carolina in Kentucky, US. People also call him the Bike Man because over the past few years, Mick has built hundreds of bikes for needy kids.

    One day in 2012, a 13-year-old boy with a broken (坏的) bike walked by Mick' s house. "I was working in my garage (车库), and he asked if I could repair (修理) it," said Mick.

    The boy's bike had broken wheels (车轮). Mick posted (发布) a picture on Facebook, asking his friends if they had the parts he needed. One friend saw the picture and gave away two used bikes. Mick took parts from each to build new wheels for the boy.

    Soon after, Mick repaired a bike for the boy's brother and one for his sister. During the year, he repaired lots of bikes for kids whose parents didn't have enough money for new ones.

    "People are throwing away (扔掉) bikes every day," said Mick.

    Mick puts the bikes and bike parts in his garage. "I take off the good wheels and use them," he said.

    Up to now, Mick has repaired hundreds of bikes and given away almost 700 newly repaired bikes. They're free, but the kids must agree to try their best to study in school.

    Mick also hopes the bikes will get kids off the sofa (沙发)" When I was growing up we all rode our bikes" he said' Hopefully these kids can get some exercise."

    John and Bobby joined the same company together just after they completed their university studies the same year. Both of them worked very hard. Several years later, however, the boss promoted(提拔) Bobby to manager but John was still a worker. John could not take it, and gave his resignation(辞呈) to the boss. He complained that the boss did not think much of those who were hard- working, but promoted only those who flattered(奉承) him.

    The boss knew that John had worked very hard for the years. He thought a moment and said," Thank you for what you said, but I hope you will do one more thing for our company before you leave."

    John agreed the boss asked him to go and find anyone selling watermelons in the market. John went and returned soon. He said he had found a man selling watermelons. The boss asked how much they cost every kilogram. John shook his head and went back to the seller to ask and returned to tell the boss $1.2 every kilogram,

    The boss told John to wait a second, and he called Bobby to come to his office. He asked Bobby to go and find anyone selling watermelons in the market. Bobby went and returned, saying. Boss, only one person is selling watermelons. $1.2 every kilogram, and $10 for 10 kilograms. The seller has 340 melons. On the table there are 58 melons, and every melon weighs about 2 kilograms. They were brought from the South two days ago. They are of good quality.

    Hearing what Bobby said, John realized the difference between himself and Bobby. He decided to stay and learn from Bobby.

 Every morning at 5 a. m., workers of Disney World Resort prepare to deliver food to the pickiest (最挑剔的) eaters: thousands of animals that live there. "We make meals tor creatures from big cats to sharks." animal nutrition assistant(营养助手) Cori Coleman says. So how do Coleman and her coworkers at the animal restaurant feed hundreds of animals every day? Nat Geo Kids takes you behind the scenes of the wildest"restaurant" ever.

 Most animals aren't"ordering" the same dish. Their food is based on what they need to stay healthy. Nutritionists use a digital program to prepare catch animal' s daily diet. "Some animals are growing, and others need to lose weight," Coleman says. "It's not as simple as giving every animal the same meal."

 After the diet is decided, the"chefs" deal with items that need to be broken down, like large pieces of fruit. Then they weigh the food to make sure each animal is getting the right amount of food. Finally, they put the meals into boxes so the food can be transported to the animals across the park.

 Keepers watch the animals to record what they like and what they don't. "Our bats love most fruit," keeper Erica Hoffstadt says. "But they can't stand strawberries!". Notes like these are shared with the nutritionists so they can displace food for picky eaters.

Billy Ray Harris was homeless. He spent each day on the streets of Kansas City, begging for money or food. Every day, as he sat thinking about his life, he occasionally heard the sound of a coin or two coming into his cup. One day, the noise was louder than usual. If Billy had looked up, he'd have seen a young lady on her way to work. But he didn't. Later when he looked into the cup, he could hardly believe what he saw. At the bottom was a shining diamond ring.

Billy's first thought was to go straight to a jeweller's(珠宝店) and that's exactly what he did. To his amazement, he was offered $4,000. Billy thought long and hard. Was this a mistake? It was more money than he'd seen in a long time. But then he thought about his grandfather, who had brought him up always to do the right thing, and knew he had to reconsider. His mind was made up. He'd keep the ring and maybe one day its owner would return.

Two days later, a young woman came while he was begging. She introduced herself as Sarah Darling and asked if he'd found anything unusual in his cup. Billy reached into his pocket and pulled out the ring. When he saw the smile on her face, he knew he'd made the right decision. She explained when putting the coins into his cup, she'd forgotten putting her ring in her purse.

But the story doesn't end there. Sarah told her husband the story and wanted to post it on the Internet. He thought it was a good idea. They also called on raising money for Billy. They had more than $185,000. Billy Ray Harris no longer spends his days begging. He has a home and a job. The story also made the local news and he was reunited with his two sisters, who he hadn't seen for 16 years. If he hadn't done the right thing, he wouldn't have seen his sisters again.
