My high school graduation is the most memorable event in my life because it was such a special day. During our graduation we were each called up one at a time to the stage. We each received our diploma and everyone applauded our hard work. I even received an award for being the best math student. There was a get-together afterwards which was attended by all my friends and family. I think study in the school that I have found some good ways to do useful things as well as have learning it. And the more I practiced in the school, the more confidence I gained. It was a memorable event because on this way I ended one part of my life and embarked on the beginning of my future.
When it comes to the most efficient transportation, I would to say it is the inter-city train. The reasons why I hold that are based on the following aspects. First of all, unlike automobile, inter-city train never costs too much oil so that it won’t cause heavy air pollution to the city. And if there is creasing air pollution, it will ease the severe global warming to some extent. Besides, it is faster than driving a car since there will be no traffic jam at all, with the time saved, we can have a nice breakfast an d even feel fresh after we arrive at our office every morning. And since there is no traffic jam, it will decrease the accidents and numbers of people’s dying from the car crash.
