    Have you ever offered a helping hand to those who are in trouble

    One day, two 1 were walking along the road to school when they saw an old woman carrying a large basket of pears. They thought the woman looked very 2. They went up to her and said,“Are you going to town? If you are, we will help carry your basket.”

    “Thank you,” 3 the woman, “you are very kind. You see I'm weak and ill.” Then she told them that she was now going to market to 4 the pears which grew on the only tree in her little garden.

    “We are all going to the 5.” said the boys. “Let us have the basket.” And they took hold of it, one each side. They walked 6 with the heavy basket, but happily.

    The other day, I saw a little girl stop and 7 a piece of orange peel (皮), which she threw into the dustbin (垃圾桶), “I wish 8 would throw that on the sidewalk,” said she. “Someone may step on it and fall.”

    Perhaps some may say that these are not 9 things. That is right. But such a little thing shows that you have a thoughtful mind and a feeling heart. We must not wait for the 10 to do great things. We must begin with little things of love.
