How cool would it be {#blank#}1{#/blank#} people could travel in tubes(管道)? They may travel to another city in just {#blank#}2{#/blank#} (minute). In the near future, this might happen not only in movies, {#blank#}3{#/blank#} also in real life. The first open-air test of the tube train took place {#blank#}4{#/blank#} May 11. It happened in the Nevada Desert, the US. Elon Musk {#blank#}5{#/blank#}(have) the idea of developing(开发) the tube train. He is the founder (创始人) of the US space company SpaceX. He calls the tube train the Hyperloop. The Hyperloop will be even {#blank#}6{#/blank#} (fast) than the plane. It {#blank#}7{#/blank#} (go) about 1,200 kilometres per hour. Planes usually {#blank#}8{#/blank#} (fly) 800 to 1,100 kilometres per hour. The company Hyperloop One is still {#blank#}9{#/blank#} (work) on the tube train. They want people {#blank#}10{#/blank#} travel using the Hyperloop by 2021.

    It{#blank#}1{#/blank#}(be)Saturday yesterday. I{#blank#}2{#/blank#}(have)no lessons. I{#blank#}3{#/blank#}(get)up at six. After breakfast I{#blank#}4{#/blank#}(go)to a farm by bus with my classmates to help the{#blank#}5{#/blank#}(farm)with the apple harvest. As soon as we{#blank#}6{#/blank#}(arrive)there, we began to pick apples. But some of the apples are too high for me to reach. So I{#blank#}7{#/blank#}(climb)up the ladder(梯子)and{#blank#}8{#/blank#}(pick)them. Some of us{#blank#}9{#/blank#}(take)baskets of apples to the truck and some put baskets of{#blank#}10{#/blank#}(apple)onto the truck.

    It was hard work, but we all felt very happy.
