Water is very important for living things. Without water there can be no l{#blank#}1{#/blank#}on earth. All animals and plants need water. Man also needs water. Water is found a{#blank#}2{#/blank#} everywhere. Even in the d{#blank#}3{#/blank#} part of the world there is some water in the air.

    As we all have found out, water may be a solid, or a l{#blank#}4{#/blank#} or a gas. When it is a solid, it may be as hard as a brick. When it is a liquid, you can pour it out of a c{#blank#}5{#/blank#}. When it is a gas, you cannot see or feel it. Although about 70 percent of the earth's s{#blank#}6{#/blank#}is covered with water, there are many places in the world still running out of water. So we should make good use of water on earth.
