One possible solution {#blank#}6{#/blank#}the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan. His idea is {#blank#}7{#/blank#}before the earth's resources are almost exhausted, it will be  {#blank#}8{#/blank#}(total)possible to change the atmosphere of Venus（金星）and so create a new world almost as large as earth itself.

    However, {#blank#}9{#/blank#} his idea is turned into reality, humans have a long way to go. On the one hand, Venus is much {#blank#}10{#/blank#}(hot)than the earth; on the other hand, there is only a tiny amount of water there.
