— Helen hasn't come back yet. I{#blank#}1{#/blank#} (wait )for her.

    Long ago there lived a kind old man. One day while walking through the woods, the old man found a butterfly's cocoon(茧). He took {#blank#}1{#/blank#} home. A few days later, a small opening appeared. He sat and watched the butterfly {#blank#}2{#/blank#} several hours as it struggled(挣扎) to force its body through that little hole.

    Then the nice man decided {#blank#}3{#/blank#} (help) the butterfly, so he cut the remaining bit of the cocoon. The butterfly then came out {#blank#}4{#/blank#} (easy). But it had a fat body and small, shriveled(皱缩的) wings. The man continued to watch the butterfly because he expected that, at any moment, the wings would enlarge and expand to be able to support the body {#blank#}5{#/blank#} would grow small in time. However, neither happened. In fact, the butterfly spent the rest of its life {#blank#}6{#/blank#} (lie) with a fat body and shriveled wings. It was never able to fly.

    What the man did not understand was that the struggle was a must for the butterfly to get through the tiny opening. That's the {#blank#}7{#/blank#} (nature) way of forcing fluid(营养液) from the body of the butterfly into its wings.

    In this way, it would be ready for flight when it achieved its freedom from the cocoon. Sometimes struggles are exactly {#blank#}8{#/blank#} we need in our life. If we {#blank#}9{#/blank#} (allow) to go through our life without any {#blank#}10{#/blank#} (difficult), it will weaken us. We won't be strong as what we could have been. And we can never fly.
