Angelo Casimiro made something new at the age of fifteen.

    Casimiro made a device(装置）. It can charge（给……充电）your cellphone as you walk! When you run, jump or walk, a pair of discs(唱片）inside the shoes can produce electricity. It can be used to charge your phone or any other devices with a USB port!

    People have to move a lot if they use the device to charge. Those who like travelling in the wild will love it. It takes about eight hours' jogging to charge a lithium-ion（锂离子）battery and two hours' playing basketball will only give the cellphone about 10 minutes' charge.

    A device called SolePower is a kind of insole（鞋垫）that can produce electricity. SolePower is like Casimiro's device, but it can fully charge a cellphone after over a four-kilometre walk. So there's a lot for Casimiro to do to make his invention（发明）better.

    Anyway, Casimiro's device is quite good. After all, his invention started something new, right?

    A passenger told an air hostess(空姐) that he needed a cup of water when the plane just took off. She told him that she would bring him the water soon.

    Twenty minutes later, when the passenger's ring for service sounded, the air hostess realized it at once. She was kept so busy that she forgot to bring him the water. Therefore, the passenger was held up to take his medicine. She hurried over to him with a cup of water, but he refused it.

    In the following hours on the flight, each time the air hostess passed the passenger, she would ask him with a smile whether he needed help or not. But the passenger never paid attention to her words.

    When he was going to get off the plane, the passenger asked the air hostess to hand him the passengers' booklet(意见簿). She was very sad. She knew that he would write down sharp(苛刻的) words. But with a smile she handed it to him.

    Off the plane, she opened the booklet, and let out a smile, for the passenger put it: On the flight, you asked me if I needed help for twelve times in all. How can I refuse your twelve sincere smiles?

    That's right! It was the twelve smiles of the air hostess that moved the passenger.

    I was in line waiting to pay. A little boy in the front was buying some clothes.

    I noticed that the little boy was paying mostly with change (零钱). It seemed that he had broken his pig bank to do this shopping. However, the cashier(收银员) told him he was $ 8.00 short after counting his money.

    It was clear that the boy had already used all the money. The lady in front of me said, "Well, I could pay half of that." I told the boy that I could pay the other half. We dug into our handbags. However, both of us only had ten-dollar bills (纸币). Other shoppers began digging into their pockets to find some change. It was amazing and touching as all these strangers seemed to react (反应) with the same mind. All wanted to be of help. Within minutes the cashier said, "I have too much money." The cashier didn't need our ten-dollar bills. Then the lady in front of me said, "Wait! I didn't even get a chance (机会) to give anything!"

    I smiled at her and said, "You did your share, because it was your idea and you started all this." The little boy smiled and thanked us. I left with a good feeling. I saw the love and goodness of others all around me. The woman in front of me smiled and said, "It feels good to give, doesn't it?" I smiled back and said, "Yes!"

    To share is simply to let someone else have or use a part of something that belongs to you. It doesn't mean we're losing anything—because what's actually happening is that we're giving ourselves more of a chance to be sincere(真诚的), which in turn makes us feel better. Sharing also means that you are not alone because others have the similar experience with you. Here is a story about learning to share.

    Once upon a time, there was a beautiful flower with beautiful colors: red, orange and yellow. The flower was very happy because everyone who saw it said it was beautiful. As time went by, she thought she was the most beautiful among all flowers. And she was very proud of her colors, but she didn't want others to enjoy them. She was worried that others would imitate her. In that case, she would not be the most beautiful in this area. So she only came out at night.

    One day, it began to rain during sunrise and didn't stop until nightfall(黄昏). When the flower woke up in the evening, she opened her petals(花瓣) and realized that she had lost all colors. Now she was all white like the snow. What had happened? The flower was so sad that she couldn't stop crying.

    Suddenly, a fairy(仙子)wearing a dress with a colorful magic stick appeared in front of her. "What's wrong with you? Why are you so sad?" she asked.

    "I've lost my lovely colors. The rain in the day has washed them away completely," the flower cried.

    "Don't worry. I can give them back to you, but under one condition…"

    "Which one?" the flower asked.

    "I want you to     ▲   . I don't want to see that you just come out at night. You should share it with others."

    Now everyone who passed by the flower would stop." This is the most beautiful flower I've seen!" many of them said. The flower was really happy because she understood that sharing good things with others was so wonderful.

Butterfly told the old Tree， "I have just come across the garden，and there I saw the Best Thing in the world. "

Dog was sitting under the old Tree and heard1 words. He thought， "the Best Thing in the world﹣now what can that2 ？It should be3 bones. I will go and find it. " Dog stood up and4 down towards the garden. 

He was running so quickly that he didn't see Rabbit5 Rabbit jumped out and asked， "Where are you going in such a hurry？"

"To find the Best Thing in the world，" Dog replied and ran even6 . 

"The Best Thing in the world？" said Rabbit. "That must be carrots. They will7 by me. " So Rabbit joined him. 

After8 while，they met Duck. 

"Where are you going in such a hurry？" asked Duck. 

"To find the Best Thing in the world，" they shouted. "The Best Thing in the world？" said Duck. "9 is better than my own little home and the warm sunshine and the beautiful blue sky. " So he stayed10 home and played among the flowers with Butterfly11 .

Dog and Rabbit ran far and fast all day long and still they didn't find the Best Thing in the world. When the day was over，they started12 back to their homes. How tired and hungry they were!

They met Butterfly halfway home. 

"Did you find the Best Thing in the world？" asked Butterfly. 

"No!" they sounded unhappy. 

"Duck has it，" she said. "13 happy with the things you have. This is the Best Thing in the world. You have tried to find the things you want most，14 ignored （忽略） the things you have now. "

The Best Thing in the world is to value15 you have.
