    No one knows exactly {#blank#}1{#/blank#}the earth began. According to a widely accepted theory, the earth began with a “Big Bang”,{#blank#}2{#/blank#}exploded loudly and produced water vapor and many gases，{#blank#}3{#/blank#} (make) the earth's atmosphere. As the earth cooled down, water appeared and stayed{#blank#}4{#/blank#} the surface. It was the presence of water{#blank#}5{#/blank#}allowed the earth to dissolve harmful gases and acids into the oceans and seas, which made {#blank#}6{#/blank#}possible for life to develop. First, the appearance of small plants encouraged the development of early shellfish and all sorts of fish. Next, green plants began to grow on land. {#blank#}7{#/blank#}were followed by land animals. So reptiles appeared for the first time. Later, dinosaurs developed.{#blank#}8{#/blank#}they suddenly disappeared. After that, mammals came into being.
