In many people's opinion, man's first real invention,{#blank#}1{#/blank#}is also one of the most important inventions in history, is the wheel. All transportation and every machine in the world depend{#blank#}2{#/blank#}it. The wheel is the{#blank#}3{#/blank#}(simple) yet perhaps the most remarkable of all{#blank#}4{#/blank#}(invention) because there are no wheels in nature.{#blank#}5{#/blank#}, then, did man come to invent the wheel? Perhaps some early hunters found that the body of {#blank#}6{#/blank#}heavy animal could be rolled through the forest on logs (圆木) more{#blank#}7{#/blank#}(easy) than they could carry it. However, the logs{#blank#}8{#/blank#}them) weigh a lot.

    It must have taken a great prehistoric thinker to imagine two thin slices of log connected, at their centers by a string stick. This would roll along just {#blank#}9{#/blank#}the logs did, yet be much lighter and easier{#blank#}10{#/blank#}(handle). Thus the wheel and axle came into being and with them the first carts.

    I wonder if it's because I haven't been able to be outdoor for so long {#blank#}1{#/blank#}I've grown so crazy about very everything {#blank#}2{#/blank#} (do) with nature. I can well remember that there was{#blank#}3{#/blank#} time when a deep blue sky, the song of the birds, moonlight and flowers could never have kept me spellbound. That {#blank#}4{#/blank#}(change) since I was here.

    One evening when it was so warm, I stayed awake{#blank#}5{#/blank#} purpose until half past eleven in order to have a good look at the moon by {#blank#}6{#/blank#}. But as the moon gave far too much light, I didn't dare open a window. Another time five months ago, I happened to be upstairs at dusk when the window was open. I didn't go downstairs {#blank#}7{#/blank#}the window had to be shut.

    Sadly …I am only able to look at nature {#blank#}8{#/blank#} dirty curtains hanging before very dusty windows. It's no pleasure {#blank#}9{#/blank#} (look) through these any longer because nature is one thing that really must {#blank#}10{#/blank#} (experience).
