"After walking through the mirror, many strange things happened to Alice. One day, she{#blank#}1{#/blank#} (meet) a unicorn(独角兽).'What－is－this? 'the unicorn asked its friend. 'That is a child,' {#blank#}2{#/blank#} (reply)the friend. 'Ah,' said the unicorn, I always thought they were fabulous monsters(传说中的怪兽)! Is it alive？'Alice then said, "Do you know,' I always thought unicorns, were fabulous monsters {#blank#}3{#/blank#}? I never saw one alive before!'"

    Fifty years before Lewis Carroll (1832-1898) wrote{#blank#}4{#/blank#} (he) stories about Alice, many people still believed in the myth (神话) of unicorns. But in the early nineteenth century, a French{#blank#}5{#/blank#} (science) named Baron Cuvier showed that unicorns were only a {#blank#}6{#/blank#} (product) of imagination.

    For hundreds of years before that, things were very different. Everybody{#blank#}7{#/blank#} (believe) that unicorns were real, but very few people saw them. Julius Caesar, who built the Roman Empire, ever said that the animal had the head of a deer, the {#blank#}8{#/blank#} (foot) of an elephant and a one-meter-long horn on its forehead. Marco Polo, who thought he saw a unicorn in India, agreed that it had elephants' feet and a horn, {#blank#}9{#/blank#} said it had a pig's head. He was almost certainly describing a rhinoceros(犀牛)! By the sixteenth century，when books about animals were {#blank#}10{#/blank#} (become)very popular, everyone agreed that the unicorn looked like a white horse with a horn.

    Jason and Andy are twins. They share a lot of things, including room, food and toys.

    One Saturday, Jason and Andy went out {#blank#}1{#/blank#}(play) with a toy car. Both of them wanted to be the owner of the car, so they shouted at each other. {#blank#}2{#/blank#}(They) mother heard the boys arguing. She came out and told them to take turns to play with the toy car, but the twins wouldn't.

    A few days later, Mother brought {#blank#}3{#/blank#} pet home. "Can't we each have our own pet dog?" asked the boys. They were {#blank#}4{#/blank#}(tire) of sharing everything.

    "No! The dog must {#blank#}5{#/blank#} (share)." Mother said. "You will have to feed the dog and make sure it does not get into anything wrong."

    Several days later, the dog got into mother's room {#blank#}6{#/blank#}(secret) and made a mess there. Jason saw the dog playing with mother's clothes. He quickly went to find Andy and told him {#blank#}7{#/blank#} the dog had done.

    "Oh, no! It's our duty to clean up the mess!" {#blank#}8{#/blank#}(cry) Andy. They boys picked up the clothes and put them away rapidly.

    "Just think, Jason," said Andy, "what a big mess two {#blank#}9{#/blank#}(dog) would made!"

    "I agree {#blank#}10{#/blank#} you," laughed Jason, "Maybe sharing isn't so bad!"
