I was nine years old when I learnt to ride a bike. The bike was a birthday present from my uncle. You can imagine how{#blank#}1{#/blank#} (excite) I was when I saw the bike, and I begged my uncle to teach me how {#blank#}2{#/blank#} (ride) it right away. However, before I got on the bike, I felt {#blank#}3{#/blank#} (extreme)  nervous and l  was  afraid  that l  would  fall  off and hurt {#blank#}4{#/blank#} (me).My uncle held onto the seat and helped me to get {#blank#}5{#/blank#} the bike. While l was riding, he was running along beside me, holding the seat so I would not fall over. I was so{#blank#}6{#/blank#} (grate) to him for his help.

    As I was practicing, I became more and more confident. Then, I heard my uncle shouting, "You are riding it by yourself now!" I was both excited and scared. I was really riding by myself, but{#blank#}7{#/blank#} if I fell off? Could I use the brakes to stop? As I was wondering about this, my uncle ran after me and got hold of the bike. I{#blank#}8{#/blank#} (slow) down and came to a stop. My heart was still beating fast when I got off the bike. {#blank#}9{#/blank#} (late) that day, having learnt how to get on the bike and get off it, I felt like l was walking on air! I am still thankful to my uncle for teaching me to ride a bike on my {#blank#}10{#/blank#} (nine) birthday.

I had no time to sharpen my axe. I have been very busy {#blank#}10{#/blank#}(try) to cut trees. "
