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.

—Yes. He won't get {#blank#}1{#/blank#} in this city because he almost knows everywhere.

    Friends are important to everyone, {#blank#}1{#/blank#}, some people may have trouble {#blank#}2{#/blank#} (keep) their friendships. Here are some tips on how to make your friendship {#blank#}3{#/blank#} (deep) and stronger.

    ★Be yourself. A lot of teens try not to lose the friendship once they become friends with some people. Though your identity (身份) is always changing, some of your personality will stay pretty much {#blank#}4{#/blank#} same. Find out {#blank#}5{#/blank#} those things are, think hard about who you want to be, and then show yourself {#blank#}6{#/blank#} (honest) to the people around you.

    ★Avoid gossip (八卦). Friends shouldn't spread rumors (谣言) about other friends. If you've heard something bad about your friends, {#blank#}7{#/blank#} (find) a proper way of asking them about it by {#blank#}8{#/blank#} (you). If you're not sure how to talk to them about it, ask a trusted friend for advice.

    ★Protect your friends. Very often, somebody that you're not close to doubts one of your {#blank#}9{#/blank#} (friend). It's important to find out both sides of the story, but it's also a good chance to show your friend that you trust him by telling him.

    ★Return the care. There are times when a friend will lend you a textbook, or a shoulder to cry on. A good friend will cheer you up when you're in trouble and listen patiently when your friend shares a problem {#blank#}10{#/blank#} you. Be sure you are as helpful as your friend, because he will take notice and feel good you.
