Johnson is an eight-year-old boy. He is {#blank#}1{#/blank#} good boy. He does well in all his {#blank#}2{#/blank#} (lesson). He loves school, and he is always active (活跃的) in class. Every time the teacher asks a question. Johnson always {#blank#}3{#/blank#} (put) up his hand quickly. Sometimes his all answer is wrong, {#blank#}4{#/blank#} the teacher always smiles and says, “Good, Johnson. But is there a better answer {#blank#}5{#/blank#} my question? ”

    One day, the teacher asks the boys and girls a question. “Swallows (燕子) fly to the south before the winter is {#blank#}6{#/blank#} (come),” he says. “But {#blank#}7{#/blank#} don't cats and dogs do the same?”

    Johnson lifts his hand as {#blank#}8{#/blank#} (usually).

    “Yes, Johnson?” says me teacher {#blank#}9{#/blank#} (happy).

    Johnson stands up and says, “Because {#blank#}10{#/blank#} (them) have no wings (膀).”

—No.She{#blank#}1{#/blank#}(prefer)the pink one．

    When I was little, my grandpa looked after me because my parents were both busy {#blank#}2{#/blank#}their work. At that time, only a few people {#blank#}3{#/blank#}(have) cars. Most people usually got around{#blank#}4{#/blank#}bike. And how did I go to the school then? Yes, I went there on Grandpa's bike! {#blank#}5{#/blank#} the bike was moving forward, it made some funny sounds that made me {#blank#}6{#/blank#}(laugh). I always clapped my little hands and sang {#blank#}7{#/blank#}(happy). Grandpa turned back over and over again to make sure my little feet would not get caught in the wheels. Grandpa was so careful {#blank#}8{#/blank#} I never got hurt in his care.

    {#blank#}9{#/blank#} a sweet memory it is! Now, I am studying in a boarding school and I miss my grandpa a lot. I wish I could relive those old {#blank#}10{#/blank#}(day).

    Strangely enough, some inventions are lost {#blank#}1{#/blank#} people can't imagine their {#blank#}2{#/blank#} (valuable). A use may need to be "invented" along with the invention. An example is the fax machine. The technology for faxing {#blank#}3{#/blank#} (invent) in the 1800s. It took more than one hundred years, however, for the fax to be seen as useful. In 1843 Alexander Bain invented a machine to {#blank#}4{#/blank#} (electrical) transmit（传输） writing. At first, it was considered {#blank#}5{#/blank#} (use) since few people thought there was {#blank#}6{#/blank#} need for transmitting writing over {#blank#}7{#/blank#} (wire). Eventually the value of the invention was realized, and it was improved {#blank#}8{#/blank#} office use. By the 1980s, the fax machine became a piece of standard {#blank#}9{#/blank#} (equip) in offices. The reason is {#blank#}10{#/blank#}it can very quickly transmit written documents. Who knows how many other inventions just need to be recognized as valuable?
