I was walking around in a store. I saw an assistant pass this little boy his money back, saying, “I’m sorry, but you don’t have enough money to buy this doll.” I walked toward him and asked him who he wished to give this doll to.
“It’s the doll that my sister loved most and wanted so much for Christmas. She was so sure that Santa Claus would bring it to her.” he said.
I replied to him that maybe Santa Claus will bring it to her, and he shouldn’t worry. But he replied to me sadly, “No, Santa Claus can’t bring it to her where she is now. I have to give the doll to my mommy so that she can give it to my sister when she goes there.” His eyes were so sad while saying this. “My sister has gone to be with God. Daddy says that Mommy is going to see God very soon too, so I thought that she could take the doll with her to give it to my sister.” My heart nearly stopped. I quickly reached for my wallet and said to the boy, “What if we checked again, just in case (万一)you do have enough money?”
“Ok,” he said. “I hope that I have enough.” I added some of my money to his without letting him see and we started to count it. There was enough for the doll and even some spare money left . The little boy said, “Thank you God for giving me enough money!”
I left the store, feeling as if my life had been changed forever.

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
"We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It's hard to get a clear result.
Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best color change. They decided it was the litmus paper!
"It's our first scientific journey, Huang said, "But it makes me want to try harder."
