One day in Africa, a mouse was hurrying home. He was going so {#blank#}1{#/blank#} that he ran right into a sleeping lion. The lion woke up and {#blank#}2{#/blank#} (catch) the mouse. "If you let me go, I'll do something for you in return(回报)," the mouse cried. "How could a small animal like you help {#blank#}3{#/blank#} a big and strong animal as me?" But the lion still let him go. "Thank you! I won't forget you," said the mouse.

    A few days later, some people were looking for wild animals. They {#blank#}4{#/blank#} (hang) a big net from three trees and tied a piece of meat to it.

    One evening, the lion made no kill and decided to return home. Just then, he smelled something delicious. When the lion found the {#blank#}5{#/blank#} , he pulled it down and the net fell down over him. The lion tried to get away but it was no use. After a while, he stopped trying. Before long, the lion {#blank#}6{#/blank#} (hear) a voice. It was from the mouse he had set free a few days ago. "I've come to help you," said the mouse. "How can you help me? I'm caught in the net and {#blank#}7{#/blank#} can help me now," the lion said sadly. But the mouse got to work, biting the net with his sharp {#blank#}8{#/blank#}(tooth). At last, he made a {#blank#}9{#/blank#} in the net big enough for the lion to escape.

    So the little mouse did what he had {#blank#}10{#/blank#} (promise) to do--help the lion. One of the nature's strongest animals had been saved by one of the smallest and weakest.

    What does it mean to be green? "Green" is more than a color. It also means taking special steps {#blank#}1{#/blank#} (protect) the environment the water, the land, and the air we breathe. {#blank#}2{#/blank#} (plant) are green, and without them the earth wouldn't be such a lovely home for us human beings.

    Sometimes people, call our society a "throwaway society". That means we are throwing away old things and {#blank#}3{#/blank#} (buy) new ones. Many times, if you no longer need something, others just might need it. For example, if you are old enough not to play {#blank#}4{#/blank#} your toys, why not give them to another family {#blank#}5{#/blank#} has a kid so that he doesn't need to buy new toys? And there will be less rubbish in your neighborhood.

    In order to keep the neighborhood "green" and make waste become renewable resources, the government of Chengdu encourages people to pack {#blank#}6{#/blank#} (they) rubbish with garbage classi-fication (垃圾分类), then send it to the bank of "junk". The bank of "junk" gives marks to every household according {#blank#}7{#/blank#} the types of waste, and if they do better in this way, they can get some daily {#blank#}8{#/blank#} (use) things.

    Through the bank of "junk", not only can a lot of rubbish be changed into recycled resources, and people can get many benefits (益处), but {#blank#}9{#/blank#} the people can develop habits of reducing rubbish and living {#blank#}10{#/blank#} (healthy).
