    There is a nature park in the southwest of our city. The government built it to{#blank#}1{#/blank#}the rare animals. The nature park has been the{#blank#}2{#/blank#}of our city.

    Yesterday my friends and I{#blank#}3{#/blank#}it. The workers there asked us not to{#blank#}4{#/blank#}animals. Many animals are in{#blank#}5{#/blank#}because people kill them for their meat and fur. Another reason is that people are taking{#blank#}6{#/blank#}their land and{#blank#}7{#/blank#}their water dirty. The{#blank#}8{#/blank#}is becoming very serious.

    I learnt much yesterday. I think people should{#blank#}9{#/blank#}up more comfortable houses for the animals and help them live in{#blank#}10{#/blank#}. We should do our best to protect them, because protecting them is protecting ourselves.

    Once upon a time, in a small village, there was a place {#blank#}1{#/blank#} the House of 1,000 Mirrors(镜子). A small happy dog knew this and {#blank#}2{#/blank#} to visit it. When he arrived, he happily climbed the stairs(楼梯) of the house. He looked into the doorway {#blank#}3{#/blank#} his tail wagging(摇动) as fast as he could. He smiled, and saw 1,000 other warm and friendly smiles. As he left the house, he thought, "This is a nice place. I will come back and visit it often.

In this village, another little dog，who was not as {#blank#}4{#/blank#} as the first one, also decided to visit the house. He {#blank#}5{#/blank#} climbed the stairs and looked unhappily into the doorway. He saw 1.000 unfriendly dogs staring at(盯着看) him. He growled(吼叫) at them and saw 1, 000 little dogs growling back at him. As he left, he thought, "This is a bad place， and I will never come back here.
