A farmer had a brother in town. His brother was {#blank#}1{#/blank#} good gardener and had the finest apple trees in the town.

    One day the gardener gave the farmer a good apple tree {#blank#}2{#/blank#} asked him to plant it. The workers {#blank#}3{#/blank#} (take) the tree to the farmer's house. The next morning the farmer began {#blank#}4{#/blank#} (think) about where he should plant it.

    "If I plant it {#blank#}5{#/blank#} the hill," he said to {#blank#}6{#/blank#} (he), "the wind might blow down the delicious fruit before it is ripe (成熟的). If I plant it near the road, people {#blank#}7{#/blank#} (see) it and pick apples. But if I plant it near the door of my house, the children may pick them."

    At last he planted the tree behind his house. But it didn't bear any apples.

    He told the gardener about that {#blank#}8{#/blank#} (sad). The gardener laughed and said, "You have planted the tree where it {#blank#}9{#/blank#} (be) exposed to cold winds, and it can't get the sun there. {#blank#}10{#/blank#} could you get flowers and fruit? You have planted the tree with a greedy (贪婪的) heart and how could you get a good harvest?"

    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.
