An Unforgettable Experience
Last summer,I had an English contest on environmental protection at the Youth Culture Palace of the city.What an unforttable experience for me!
The contest,whose aim was to let more people know the bad environmental conditions we are facing and the urgency of protecting it,was hosted by the Environmental Protection Burua.Fifty top contestants from twenty schools throughout the city took part.All of them were required to answer the questions in English in ten minutes.In order to prepare for it,I went through a very hard time.
When I was chosen to attend the competition,I felt nervous first,for my English was not good.But after a deep thinking,I made a decision that I should go for it.That's a very good opportunity for me to improve my English,as well as know more about the environmental protection which is of great importance to us human beings.I began to learn English very hard,paying much attention to the knowledge of environmental protection,such as using environmentally friendly bags instead of plastic ones,saving water and electricity and taking a bus and underground when going out.That's hard work,but I enjoyed it.
The exciting time came at last.On the morning of July 27th,2010,thousands of people crowded at the Youth Culture Palace,watching the contest.Now it was my turn to perform.I was a little nervous at first.I tried to calm down.Soon I was OK.I answered the questions one after another,no mistakes occurring.Ten minutes passed by,I went back to my seat,smiles on my face.I did a good job.
To my great delight,the first prize came to me.I knew I deserved it.Hard work leads to success.
