I like sport,but have no chance,because i am always busy,mum lets me do my homework,one time,our school had a sport meeting when i was in the primary school（小学）,i was about ten years old .I knew it was difficult to won the race,but i still joined in,i liked it.
the day was very hot,we all were sweating,and i was lightly nervous,too many classmates were watching,when the race started,i did my best to run,but i was behind,i told myself that you must insist.that was a chance to show myself.finlly i get the second place.
afer it,i know,sometimes,we must insist for our dream.
这篇应该没问题,如果你要改时间可以把ten years old 改成其他,里面用的是过去式还是得自己经常练习写写,这样写作水平才上的去
