    Clothes are traditionally made of natural materials, such {#blank#}1{#/blank#} cotton, leather and wool. They are all from plants or animals, but that doesn't mean they are {#blank#}2{#/blank#} (friend) to the earth. For example, farmers sometimes have {#blank#}3{#/blank#} use a lot of chemicals to grow cotton plants.

    Scientists now {#blank#}4{#/blank#} (look for) new ways to make clothing materials. They hope the new materials are both comfortable and good for the earth. So far, scientists{#blank#}5{#/blank#} (work) out how to make materials out of corn husks (壳), chicken feathers and rice straws. I think more and more people will like to buy these kinds of clothes.

    I still remember the first time I left home for several {#blank#}1{#/blank#} (night). I was going to a summer camp for a month. When my parents told me about the camp, I was {#blank#}2{#/blank#} (excite), because there were lots of activities there.

    The whole family drove me to the camp. When we arrived, I saw a lot of kids, but I didn't know {#blank#}3{#/blank#} (someone). I began to feel nervous. They gave me a little card {#blank#}4{#/blank#} my name on it. Then, who looked {#blank#}5{#/blank#} (old) than me, came up to me and said "Hi, Margie! I'm Sara. Our cabin is the Pines."

    Finally the time came when my parents said, "Well, Margie, goodbye. Have {#blank#}6{#/blank#} great time. And don't worry, we'll write to {#blank#}7{#/blank#} often."

    I had an awful feeling. I wanted {#blank#}8{#/blank#} (cry). But just then another girl of my age came up to me and {#blank#}9{#/blank#} (say)"Hi, are you Margie? I'm Tammy. I'm in the Pines too. Come on. Let's go to see the horses."

    Finally I had a {#blank#}10{#/blank#} (wonder) month at camp.
