    Children today have many things to play with. They can watch television, surf {#blank#}1{#/blank#} Internet, or play video games. But what do you think children {#blank#}2{#/blank#} (do) for fun long ago? They read books. 

    Some of you might ask, "Are books {#blank#}3{#/blank#} (real) fun?" Believe it or not, books provide many things that television or computers cannot. Since books use only words {#blank#}4{#/blank#} (tell) a story, they can improve your imagination. You can picture the characters and background in your head and you can also imagine {#blank#}5{#/blank#} the characters feel.

    The words and sentences that are used in storytelling are also very interesting and usually cannot {#blank#}6{#/blank#} (find) often on television or on websites. They are sometimes so beautiful and touching {#blank#}7{#/blank#} they can bring tears to your eyes

    Books also help us to think harder and {#blank#}8{#/blank#} (deep). As we continue to read, we ask questions to {#blank#}9{#/blank#} (our) and try to find answers.

    These are some of the {#blank#}10{#/blank#} (reason) why books are so fun to read. Remember: the more you read, the more you grow.
