After the final exam of Grade 3 in June, everything blew onto our faces : teachers’ changing , harder and harder texts , terrible pressure and of course the graduate exam .Where your position was on the listboard became the most important thing in our life .We had to study hard day and night ,always from 6:00 a.m. to 1:00 or 2:00 a.m. the next day. But I must say that it’s really an unforgettable memory in my life. Under the pressure we lived our life to the fullest, and enjoyed the true interesting things that we may have never cared before. Grade 4 in junior school was a turning point in my life. My attitude to learning, my world outlook and my philosophy of life all changed. I turned to be positive and strong. I also gained many people’s true & pure friendship, both teachers ’ and classmates’. In some way, I like that kind of life, as it taught me many things I’d never learned before.Teachers also helped me a lot. I still can’t forget that my history teacher talked to me until 10:00 p.m. on April 30th, 2003, for my application. My head teacher also encouraged me, so did my Chinese teacher. I should say, all my teachers worked very hard and always neglected their sleep and meals. Even if some of them were about 50 and often fell ill, they never left us one day .The last and greatest challenge was of course the final exam, also my high school entrance exam. I felt very well and comfortable except my chemistry physics exams. The result proved that I couldn’t have done worse in them. But in total, my mark is O.K. So then I became a student in the best high school of Hubei Province.We, teachers and students, got together in East Lake Hotel on June 4th, 2003. At the moment of saying goodbye, I felt that my time of junior had gone ,and my senior time was coming .Today, I looked at my graduate photos again ,and ,I smiled .He once hesitated ,struggled, feared and doubted, like an ordinary man would do. But he just "stays at the door of fate", as the name of his newly-written book says, and waits till the door opens instead of leaving during the half way. Then there comes a wholly new world where the beautiful dream lies . 。
The Most Unforgettable Experience
My summer holiday has been over. During my summer holiday, I did a lot of things. In my eyes, the most unforgettable thing I have done was that I took a boat in a beautiful lake with my senior high school friends and we barbecued on the boat.
On the boat, we ate the delicious food which is cooked by one of my friends. How wonderful it was! Here came some wind, mild and comfortable. Meanwhile, we talked with each other about something interesting that happened in senior high school. As time went by, we ate a large amount of yummy food and talked about plenty of fantastic experiences. That was really satisfying.
Nowadays,the new semester has already started and we have to go to different cities to attend school. We may meet each other in the winter holiday. What a long time! I really miss my true friends. It is the time staying with them that makes me feel delighted and relaxed. Therefore, I hope that we can meet again as soon as possible.
