I am a student in a middle school. In my class, there are{#blank#}1{#/blank#}（十六）boys. My friend, David, is one of{#blank#}2{#/blank#}（他们）. His {#blank#}3{#/blank#}（生日）is the same as mine. This year I want to give him a(n){#blank#}4{#/blank#} (/blu:/) pencil-bag, because it is his favourite colour. We always play{#blank#}5{#/blank#} （篮球）together after school on Thursday. When we are  {#blank#}6{#/blank#}（累的）, we sit down on the playground and {#blank#}7{#/blank#} (/lisə:n/) to the students singing in the classroom. We sometimes go to the {#blank#}8{#/blank#} （剧院）on Sunday. But when it is cold, we like doing homework in my home together. My English is good and his {#blank#}9{#/blank#}（数学）is good. We can help each other. We draw  {#blank#}10{#/blank#}（图画）together, too. I like my friend a lot.

    The most important drink is water. Not many people understand this but it is quite true. People can l{#blank#}1{#/blank#} for a long time without food, but they will die in two or three days w{#blank#}2{#/blank#} water. In h{#blank#}3{#/blank#} weather, many people do not drink e{#blank#}4{#/blank#} water, because they don't know how much water they n{#blank#}5{#/blank#}. After taking exercise, people need more w{#blank#}6{#/blank#}. The water in the man's body is m{#blank#}7{#/blank#} more than other matters. We'd b{#blank#}8{#/blank#} have enough water, or we may get ill.

    Water is necessary to all the living things. "There will be no l{#blank#}9{#/blank#} if there is no water."

    So we must save water and don't w{#blank#}10{#/blank#} water.
