    Have you ever been cycling(骑自行车运动)? This spring my elder brother and I {#blank#}1{#/blank#} (spend) a long weekend cycling in the countryside. We rode {#blank#}2{#/blank#} (slow) along because we hadn't come to break any speed records or do sports. We just wanted {#blank#}3{#/blank#} (get) some fresh air and a break from schoolwork. We really had a great time {#blank#}4{#/blank#} (ride) along country roads. And there was one of the best things about our trip that made us happy:

    Every few {#blank#}5{#/blank#} (kilometre) there was a village where we could find everything we needed.

    All the local people were really friendly. However, {#blank#}6{#/blank#} second day, something happened. We were going down the hill when my brakes(刹车) started making {#blank#}7{#/blank#} noise, but I didn't mind at all At midnight we were woken up by the noise in the hotel. We were tired {#blank#}8{#/blank#} we set off the next morning, but soon felt cheerful when the sun came out.

    What we enjoyed {#blank#}9{#/blank#} (much) about cycling is—it's simple and fun. I think nothing is {#blank#}10{#/blank#} (good) than cycling if you're looking for a break that is active and cheap.

    Why not have a try?
