Every society has {#blank#}1{#/blank#} (it) special words, expressions and ways of saying things. One of the popular expressions in the United States is "Hitting the books". It {#blank#}2{#/blank#} (mean) studying a subject with great effort(努力).

    One of the great challenges for students {#blank#}3{#/blank#} (be) taking tests. Students spend long hours {#blank#}4{#/blank#} (prepare) for a test. They read all their books carefully, and then read them {#blank#}5{#/blank#} second time and a third time. They prepare for every possible question. They study every night. They are "hitting the books."

    In the United States, most children go to school {#blank#}6{#/blank#} they are five years old. Public education is free and most children go to schools near their homes. School in these early years is fun. Children learn {#blank#}7{#/blank#} (read) and write, but they also play games and go on trips. There is no reason at such an early age for them to hit the books.

    This situation changes as children become older. The subjects become {#blank#}8{#/blank#} (difficult). Students must learn {#blank#}9{#/blank#} world history, algebra(代数) and life sciences. Tests become more common.

    Pressure is growing to hit the books, study hard, and advance(升级). {#blank#}10{#/blank#}, most students only really begin hitting the books for long hours when they reach high school.

Knowledge is a prize that is not easy to gain.

    Over a river there was a very narrow (窄的) bridge. One day{#blank#}1{#/blank#}goat（羊）was crossing this bridge, just at the middle of the bridge he {#blank#}2{#/blank#}(meet) another goat.

    There was no room（空间） for them {#blank#}3{#/blank#}（pass）.

    "Go back," said one goat to the other. "There is no room for both of us."

    "{#blank#}4{#/blank#} should I go back?" asked the other goat. "Why don't you go back?"

    "You must go back," said the first goat, "because I am {#blank#}5{#/blank#} (strong) than you." 

    "You are not bigger than me." said the {#blank#}6{#/blank#} (two) goat.

    "We will see about that." said the first goat, and he put down his horns(角){#blank#}7{#/blank#} (fight)打架.

    "Stop!" said the second goat. "{#blank#}8{#/blank#} we fight, we will both fall into the river and die. Instead, I have a plan--I shall lie down, and you may walk over me."

    Then the clever goat lay down on the bridge, and the other goat walked{#blank#}9{#/blank#}him lightly. So they passed each other, and went on {#blank#}10{#/blank#}（they）ways.
