　　高中生英语演讲稿：Olympics of mankind

　　Good morning, everybody!

　　Let's start with the very simple question: Do you know the tree coverage rate of Beijing? Well, the recent numerical value is 49.9%. It sounds much, but is there simply one tree that was planted by you? If there is, let's say you're really great. But if not believe me you are not alone cuz it's rather difficult for us students to get involved in such activities. Well, I think now we all realize that all that we've done for the green is just about claiming or declaring, painting or advertising. However what I'm fully convinced is that someday ten years ago you must have stepped onto the grassland in the early spring and I'm sure that some of you must have unwittingly picked up dandelions by the roadside and gently blew their parachute like seeds into the fragrant breeze. By the time our lives can be counted by decades, what have we done for our mother nature?

　　Before you get lost in speculation, please follow me and try considering some other questions: put up your hands if you have watched the Olympic Games? nonetheless how many of you had the experience of sitting in front of the television waiting for the Games of the unable people? I think now we can draw the conclusion that we concern the Olympic games mostly for entertainment.

　　Have you found out that the linkage between the Olympic Games and the green environment is that we almost do nothing really helpful to either of them! What now I want to tell you is very realistic I wrote them from the core of my heart so please believe me they are my true feelings.

　　Last summer when I had just finished the high school entrance examination, I came up with the idea of not using air conditioners in that coming summer. Then I had an extraordinarily hard time controlling myself and had suffered from having more than one air conditioners in sight yet cannot make use of them. Every time I caught sight of them I told myself that I was doing something quite valuable. Finally autumn came and to my surprise I had made it! You know how excited I was? I really felt very proud of myself. Sounds ridiculous right? However, will all of you here join me to do this next year, will you? I hope so. Because I feel deeply upset every time when I see my parents waste a lot of water and I don't know why I'm extremely concerned about the protection of environment and the reservation of natural resources since I was young. My mother was against me on whether to mention her in my speech nevertheless I consider it very common among you and maybe your parents. In the past I didn't dare to ask others to turn off the faucet while not using them because I was afraid of being described as stingy, am I? Stinginess is to resources what responsibility is to the society. It's about time we aroused the social awareness of environment protection. Doesn't the realization of our green dream and Olympic dream both start from that?

　　Because all the beautiful words seem to be so pale and feeble compared with practical actions and I don't like to say sentences like "start right from myself" so let's change it to a more romantic one: the mission of turning the green within our heart and soul into the luxuriantly green scenery out of the window is bound to cross the boundaries between nations, continents and racial groups, from Olympia to the Great Wall and finally fall on our shoulders by the year 20xx.
