It was a fine day in autumn. Some girls and boys were out {#blank#}1{#/blank#} their teacher. They {#blank#}2{#/blank#} to a museum. On their way to cross a bridge, they suddenly(突然地) heard a loud shout behind {#blank#}3{#/blank#}. The teacher told her pupils{#blank#}4{#/blank#} . Then she turned and listened. When she heard the cry“Mad dog!”she knew what was happening. {#blank#}5{#/blank#} she could do anything, she saw a dog running to them.“{#blank#}6{#/blank#}”said the teacher, “keep close to each other. Don't move or cry.” Then she stood before the children so that the dog would meet her first. The animal came quickly.

    At this moment the teacher saw a man. He ran up with a gun(枪) in his {#blank#}7{#/blank#}. “The children must be kept safe {#blank#}8{#/blank#} the man comes.” Thought the lady. The teacher ran to the dog, facing it bravely. The mad dog snapped(猛咬) at her and she fell down. The man came and killed the animal. The dog had bitten her so {#blank#}9{#/blank#} that the brave lady died soon after the doctors arrived. She lost her life for her {#blank#}10{#/blank#}. When people heard of this, they said, “The brave lady will always be remembered among us!”

    Our music teacher's {#blank#}1{#/blank#} song is Old Mac Donald Had a Farm. She is a good teacher and she is{#blank#}2{#/blank#} to us. We all love her. All of the children in our class love to sing this song. We like to make the sound of the animals.{#blank#}3{#/blank#} the chicken we make the sound "cluck, cluck". For the pig we make the sound "oink, oink "and for the duck we say "quack, quack,"

    One day our teacher {#blank#}4{#/blank#} us to draw a picture of what Old Macdonald's farm may look like. I {#blank#}5{#/blank#}  good at drawing pictures. First I drew Old Macdonald. He is a {#blank#}6{#/blank#}. Then I drew the farm animals. I even drew cows saying "moo"! Around the cows I drew grass for them {#blank#}7{#/blank#} I also drew a garden for Farmer Macdonald to grow{#blank#}8{#/blank#} for his family. {#blank#}9{#/blank#}I drew a house for Old Macdonald and his family to live in. The music teacher hung all of our pictures on the wall. She{#blank#}10{#/blank#} we did a great job!

    Free energy is everywhere around us. There are many ways to make and collect energy from{#blank#}1{#/blank#}sources(来源)like the sun, wind, water, etc. But people always make things difficult by not using these sources of energy. In the last few years there have been a great number of new ideas for generating(产生)energy. People suddenly realized that everyday things can be a source of energy. For example, riding a bike running or just{#blank#}2{#/blank#}, ate. But, is there anything else that can be used for collecting energy? We{#blank#}3{#/blank#}have to change our way of thinking if we want to change the world.

    So comes the idea of solar(太阳能)roadways. Are they the road of future? Why don't we use them for collecting energy?

    The US Department of Transportation{#blank#}4{#/blank#}$100. 000 to Solar Roadways to build the first ever Solar Road.
