        It was the first biology class.  The teacher wanted to give a good start to her{#blank#}1{#/blank#}   . she wanted to open up her students' {#blank#}2{#/blank#}   to the world of biology . She knew that teaching those young students was not {#blank#}3{#/blank#}  , so she worked hard and {#blank#}4{#/blank#}    to find a good way to teach  them . After {#blank#}5{#/blank#}   a long time , She had an idea . She decided to show the children {#blank#}6{#/blank#}   interesting and give them a lesson at the same time.
She asked her students to watch{#blank#}7{#/blank#}  . Then she began . She put a  worn(虫) into a glass of water . the worn {#blank#}8{#/blank#}   around in the water . Then she put a second worn into a glass of alcohol(酒). It was killed after a few {#blank#}9{#/blank#}   .  She asked the students {#blank#}10{#/blank#}  they learned from it .

    A female swimming athlete once set a goal ( 目标) for herself. She decided to swim across the English Channael before she retired. If she could succeed, she would be the first person in the world {#blank#}1{#/blank#} did it. On that day ,she jumped into the sea without any hesitation(犹豫) and swam towards the opposite bank without any {#blank#}2{#/blank#}. In the journey, she faced heavy fog, heavy rain and heavy waves. Though she was {#blank#}3{#/blank#} , she still carried on swimming. But in the end, she gave up. And she didn't know that the opposite bank was only one mile away when she gave up.

    Later she was {#blank#}4{#/blank#} about the reason. And she said, "The reason why I gave up is that I could not see the place which I was going to reach  {#blank#}5{#/blank#}" It was a great pity that one mile broke her dream.

    Since we were young {#blank#}6{#/blank#} , too many success stories have been telling us about courage and persistence(坚持). But they never told us where to {#blank#}7{#/blank#} courage and persistence. You can only have courage when you know where your goal is. You can only manage to persist when you know where your goal is.

    And that's because when you know where your goal is, you can, only prepare {#blank#}8{#/blank#} well in the mind. Courage and persistence never {#blank#}9{#/blank#} from the sky. They come from weighing between input and output.

    A life without goal is {#blank#}10{#/blank#} a ship without a compass. It goes nowhere. There is no courage or persistence in a life without goals.
