Our school is a green school．What makes it green？

    First，we have a lot of trees．There are trees in front of and behind every building．Some trees are green only in spring and summer．And some are green all year round．The trees make our school look like a big forest.

    And our school is a green one because we "go green". How do we go green？We have two green days every month．On green days，no students or teachers go to school by car．And we have clean﹣up Day every month．That day，students go to streets to pick up rubbish．Also，we have tree﹣planting Day every spring．We plant young trees on hills．We have three green clubs The members of the clubs look after those trees well．

    Green is not only a colour．It is about life．Please go green with us and make the world a more beautiful place．

While the man ____ (run) back home, he saw a dog by the side of the road.

   Yesterday my son, daughter and I went to the grocery store. In front of us in line was a little girl with her mother. The little girl was asking her mother for a box of Smarties. The polite way she was asking almost broke the mother’s heart, “I’m sorry, Honey, but we have no money to buy it ”
   My son was watching that dialogue. By the way, he had been raking(用耙子耙)leaves our garden to raise himself some money to buy a bike. As he watched the mother and daughter leave the store, he ran to the candy counter(柜台)and bought a box of Smarties with the money .
He turned to look at me and I just nodded. He ran out after the little girl and her mother and he gave them the box. He came back and told me what he told them. “Every kid should have a pack of Smarties because they can make you smart.”
   I was so excited that I bought a pack of Smarties for my son. I told him that I was proud of him, and that was for his act of generosity(慷慨)because he gave his own Smarties to others  Quickly, he replied, “But you do nice things for people and you never get anything for it .”explained, “when you do something nice for someone, you shouldn’t expect to get anything, when you do get something you should be very thankful.”
