"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.

    Spring Festival is l he start of a new lunar(阴历的)year.

    Before Spring Festival, people sweep {#blank#}1{#/blank#} bad luck so that the new year will start with good luck. There are a lot of {#blank#}2{#/blank#} (tradition) for Spring Festival. People clean {#blank#}3{#/blank#} (they) houses, cut their hair, and buy lots of new clothes to {#blank#}4{#/blank#} before Spring Festival. They paint the doors red, {#blank#}5{#/blank#} red is a "lucky colour".

    Old people give young people {#blank#}6{#/blank#} (luck) money. People eat jiaozi {#blank#}7{#/blank#} the evening before Spring Festival.

    Then there {#blank#}8{#/blank#} (be) a dragon dance and a lion dance. {#blank#}9{#/blank#} (this) bring good luck for the new year. It's {#blank#}10{#/blank#} Great time, and everyone feels happy.

    Next time you hold a book in your hands, stop and think. Like most other things in the modern world, it is the result of thousands of years of human invention.

    First came the invention of writing, {#blank#}1{#/blank#} (probable) about 5,500 years ago. With writing, people did not have to remember everything in their heads. They could communicate with people that they never {#blank#}2{#/blank#} (see) and share their knowledge with future generations.

    Later, the Greeks were well-known for their literature (文学) and science, but their "books" looked very different f {#blank#}3{#/blank#} the books of today. They were called scrolls (卷轴).They were difficult to use and took a lot of space in a library. About 2,000 years ago, books with lots of pages {#blank#}4{#/blank#} (invent).

    For more than a thousand years, the pages of books were made from animal skin. That changed in t{#blank#}5{#/blank#} thirteenth century, when Europeans learned about a very {#blank#}6{#/blank#} (use) Chinese invention: paper.

    But the biggest change for books in Europe came in 1439, when Johannes Gutenberg invented the printing press. Before that, books in Europe were copied by hand, so they were very expensive. Many more people could afford the books {#blank#}7{#/blank#} were produced on a printing press.

    These days it is difficult {#blank#}8{#/blank#} (imagine) a world without books. But human invention does not stop. Every year, more {#blank#}9{#/blank#} (story) are bought as e-books and read on a screen.

    Will anyone turn the pages of a traditional book in the future, {#blank#}10{#/blank#} will books, like scrolls soon disappear?
