Man has been interested in the outer space for thousands of years. It has been almost over forty years {#blank#}1{#/blank#} man's first landing(登陆) on the moon. Now, some people believe that space exploration(探索) is a waste of time and money. It is true that it {#blank#}2{#/blank#} (cost) billions of dollars to develop the space research, but people just get {#blank#}3{#/blank#} little information.

However, every coin has two sides. There {#blank#}4{#/blank#}(be) still a lot of other people who believe that space exploration has more {#blank#}5{#/blank#}(advantage). And I agree with them. Many new products, such {#blank#}6{#/blank#} weather and communication satellites(交通卫星), are also products of space programs, and they are good {#blank#}7{#/blank#} people all over the world. And what's more, people {#blank#}8{#/blank#}(know) about some scientific knowledge of the outer space already.

    We believe that it will bring much{#blank#}9{#/blank#}(many) advantages in the future, which we can not even imagine now. That's why several countries are trying hard {#blank#}10{#/blank#}(carry) out space exploration all the time. Let's wait and see.
