　Every day, 15-year-old Martha wrote on the Internet about the meal she ate at school. She also took pictures of the food. However, Martha was very honest about the food. She did not just describe the food. She judged the taste and health of the food.

　Martha also began to use her blog (博客) for an important reason. She began to raise money for the organization Mary's Meals in the East African country of Malawi. It provides food for children in schools for free. Martha encouraged her readers to send money to Mary's Meals to help build a kitchen.

　But then, Martha began to have a problem. Many people read her blog. She became big news. The news stories showed that the food at Martha's school was not always healthy. And that made some people angry. So the school officials decided to stop Martha's blog. They said that she could not take her camera to school.

But an amazing thing happened. Many people began sending messages of support across the Internet. Martha's story was even bigger than before. Now the officials had to change their minds. A few days later, Martha was again writing her blog. But more than that, people had sent a lot of money for the Malawi school children. Martha had hoped to raise about 10,000 dollars. But the total reached 100,000 dollars and still kept on growing!
