    The summer holiday was coming but Zach was a little sad. He would have to move {#blank#}1{#/blank#} the holiday, leaving his friends and his tree house. The tree house was Zach's favorite place to go to when he wanted to be alone. He also liked {#blank#}2{#/blank#} his friends there. They would play for {#blank#}3{#/blank#}.

    Zach told his mom, "I don't want to move. I'm going to miss my friends. I'm also going to miss my tree house. I want to take it with me." "Zach, but we have to {#blank#}4{#/blank#} your father's changed his job. He is already {#blank#}5{#/blank#} waiting for us. You will have a much {#blank#}6{#/blank#} bedroom, and you will meet new friends at your new school," {#blank#}7{#/blank#} his mom. Zach wasn't so sure.

    When Zach and his mom arrived, Dad took Zach to the backyard. There, Zach saw a big tree house. "Wow!" Zach shouted. "This is great!" All of a sudden, Zach heard a {#blank#}8{#/blank#} voice. "Are you moving in? My name is Joey and I live next {#blank#}9{#/blank#} Can I have a look at your tree house?"

    "I think I'm going to {#blank#}10{#/blank#} it here after all!" Zach told his mom and dad that night.

A: Where did you go last night?

B: One of them could. {#blank#}4{#/blank#}it offered customers food, it could answer their simple questions. Though its voice sounded a little strange. It could speak very {#blank#}5{#/blank#}.

A: How wonderful! I hope I can go.

    People can imagine life without water. Without it, the earth we live on would be a dead one. There would be no trees, no crops, no animals and no people. So water is considered to be next to{#blank#}1{#/blank#} in importance.

    Although nearly three quarters of the earth's surface is covered with water, it is sea water and {#blank#}2{#/blank#}. The demand for water is increasing, while water{#blank#}3{#/blank#} are scarce.

    Agricultural production needs enormous amounts of water, so does industry. Besides, the rapid growth of population makes it more and more difficult for people to{#blank#}4{#/blank#}because of the water shortage. So water shortage has become one of the most serious problems.
