the most unforgettable experience in my life（不管多少个字）

My unforgettable experience
\x09As we grown up,we may experience many things .Some experience are happy,while some experience are bad.Why we always keep part of our experience in mind Then,I'd like to say ,because they are meaningful and we can learn from them .
\x09I'd like to introduce you one of my unforgettable experiences .About one year and a half ago ,I went to Changsha to attend an examination with my friend .The exam was divided into two parts ,one was in the morning ,and the other one was in the afternoon .When the first one finished at 10:40 ,my elder sister took my friend and I to have lunch .After lunch ,we went to my sister's school to review my next exam .However ,both my friend and I regarded the exam began at 2 pm.,in fact it began at 1 pm..When we reached the examination room ,it was already 1:35 .What's more ,it was rules that the person who was late over 20 minutes could not attend the exam .We were very anxious and feared ,begged the teachers to allow us to attend the exam ,at last the teachers let us come into the examination room .How breathtaking it was !After the exam ,I said thanks to the teacher ,the teacher said ,"Be careful next time ,and te links to your benefits directly ."
\x09After this matter ,I have a deep thought ,no matter what we do ,you must be careful and make everything accurate before .I learned a lot from this experience ,and it would exists in my mind for a long time to alert me to be careful in any case .
