Do you often help the people who are in need?
One day, two boys were walking along the road to school when they saw an old woman carrying a large basket of pears. The old woman looked very tired. They went up and said, “Are you going to town? If you are, we’ll help you carry your basket.”
“Thank you,” said the woman. “That’s very kind of you.” Then she told them that she was going to the market to sell the pears. So the boys decided to lift the basket together. They walked slowly with the heavy basket, but they were happy.
The other day, I saw a little girl pick up a piece of banana peel(水果皮). She threw it into the dustbin(垃圾箱). “I  hope nobody would throw that on the street,” she said. “Someone may slip (滑倒) and fall.”
Perhaps some people may say that these are not great things. That’s right. But almost all great things are made up of such small things. We shouldn’t wait for the time to do great things. We should begin with these things that are full of love.
