It was early May. As soon as Sophie got home from school. She {#blank#}1{#/blank#} (打开) the mailbox at the gate. There was only one {#blank#}2{#/blank#} (信) in it and it was for Sophie. It looked really {#blank#}3{#/blank#} (奇怪的), because the envelope(信封) didn't say who it was from. There was no stamp on it, either.

    Sophie took out the paper. It read, "Who are you?" Nothing else, only the three words, written by hand and followed by a large question mark. "Who wrote this?" Sophie said to {#blank#}4{#/blank#} (她自己). "Maybe a naughty(淘气的) child in the neighborhood, I {#blank#}5{#/blank#} (猜测)."But she couldn't stop thinking about the question. After half an hour, she said, "Why am I {#blank#}6{#/blank#} (浪费) my time on it? I'll not think about it {#blank#}7{#/blank#} (再也)." However, the next day Sophie {#blank#}8{#/blank#} (注意到) another letter in the mailbox. In it there was only one sentence, "Where does the world come from?"

    Why did someone write to Sophie? What did the questions {#blank#}9{#/blank#} (意思是)? Could Sophie find out the {#blank#}10{#/blank#} (事实)? I think maybe you should find out the answers in the famous book, Sophie's World, by yourself.

    {#blank#}1{#/blank#} (million) of words have been written about young people in the USA. There are reasons for this great interest in their ideas, {#blank#}2{#/blank#} (feel) and actions. Today there are about seven million {#blank#}3{#/blank#} (America) in colleges and universities. Young persons under twenty-five make up nearly half of the American population. Many of {#blank#}4{#/blank#} (this) will soon be in charge of the nation. Naturally their ideas are important {#blank#}5{#/blank#} everyone in the country, and it is necessary for older people {#blank#}6{#/blank#} (understand) what they think and feel. College students today have strong opinions about right and wrong. They are deeply interested in {#blank#}7{#/blank#} (make) a better life for all people, {#blank#}8{#/blank#} (especial) for those who have not been given a fair chance before now. They see much that is wrong in the lives of their parents. {#blank#}9{#/blank#} is hard for them to see what is right and good in the older ways. As {#blank#}10{#/blank#} result, there is often trouble in American families.

    Miss White comes into the classroom. She sees some school things on the teacher's desk. There is a pencil box, a red pencil, two black {#blank#}1{#/blank#}(pen) and {#blank#}2{#/blank#} orange notebook. Whose are they?

    Miss White asks Tina, "Tina, is this {#blank#}3{#/blank#}(you) pencil box?" Tina says，"Yes, it is. Thank you." "Are{#blank#}4{#/blank#}(this) your pens?" asks Miss White. "No, they {#blank#}5{#/blank#}. They're {#blank#}6{#/blank#}(Mary)," says Tina.

    Miss White goes to Mary and says, "Are these your pens, Mary?" Mary says, "Yes, {#blank#}7{#/blank#}are. Thank you." "What {#blank#}8{#/blank#} the red pencil? Is it {#blank#}9{#/blank#}(you), too?" Miss White asks. "No, it isn't," says Mary, "I think it is Bob's, please ask{#blank#}10{#/blank#}(he) ."

—Yes, I do.
