小学英语演讲稿1分钟的自我介绍
Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life. Youth means a tempera-mental predominance of courage over timidity, of the appetite for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20. Nobody grows old merely by a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spring back to dust. Whether 60 or 16, there is in every human being’s heart the lure of wonder, the unfailing childlike appetite of what’s next and the joy of the game of living. In the center of your heart and my heart there is a wireless station: so long as it receives messages of beauty, hope, cheer, courage and power from men and from the Infinite, so long are you young. When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old, even at 20, but as long as your aerials are up, to catch waves of optimism, there is hope you may die 青春不是年华，而是心境；青春不是桃面、丹唇、柔膝，而是深沉的意志，恢宏的想 象，炙热的恋情；青春是生命的深泉在涌流。
青春气贯长虹，勇锐盖过怯弱，进取压倒苟安。
如此锐气，二十后生而有之，六旬男子则更多见。
年岁有加，并非垂老，理想丢弃，方堕暮年。
岁月悠悠，衰微只及肌肤；热忱抛却，颓废必致灵魂。
忧烦，惶恐，丧失自信，定使心灵扭曲，意气如灰。
无论年届花甲，拟或二八芳龄，心中皆有生命之欢乐，奇迹之诱惑，孩童般天真久盛不衰。
人人心中皆有一台天线，只要你从天上人间接受美好、希望、欢乐、勇气和力量的信号，你就青春永驻，风华常存。
一旦天线下降，锐气便被冰雪覆盖，玩世不恭、自暴自弃油然而生，即使年方二十，实已垂垂老矣；然则只要树起天线，捕捉乐观信号，你就有望在八十高龄告别尘寰时仍觉年轻。

Cherish the water My dear Teachers，fellow students and friends： Good afternoon．As we all know, the earth is a planet almost covered by water，and it is water made every thing on the earth lively．Water is also one of the important part of our environment．Though，is there really so much water for us to clean，to produce many things，to play with? how much water are there on the earth then?Most of the water is in the oceans or locked away as ice．The largest volumes of fresh water are stored underground as groundwater，imagine there is only one barrel of water in the world，then there is only a spoon of it on the land，and the water we can use is only a drop of it．Now I have to remind all of you here that the single drop of water is never as Clean as before，it has been polluted severely by our human beings．There is a very beautiful river in Paris．It is the Seine，it runs across the City，people drink coffee, chat on the bank in the day，at night，they enjoy the beautiful scenery in the boat，songs from the river fly into the Sky made the river more attractive, the Seine is a famous symbol of France；on the west coast of pacific ocean there lies the modern City Shanghai，another river which used to be a very important transportation route runs through the center of the city，people respected and regard it asmother．It is thesuzhou river，but l believe that few of you would sit beside it，people will be scattered by the terrible smell of water when walk by．I have to say it is extremely dirty! And we all know that a lot of beautiful rivers in the world also are Sharing the same fate with suzhou river． Who is the devil? I can't help asking．Many human activities and their by-products have the potential to pollute water. Please have a look along the banks of the river, large and small industrial enterprises discharge dirtywater, tons of garbage were thrown into the river, the water contained so much that it can't clean itself. Compared with the dramatic development in many sides of Shanghai, the suzhou river has become a black point of the appearance of city.Fortunately, the government has control the situation now, we are happy to see some parts of the river has become clean again, and we even can find fish sometime.The unique earth is the only planet full of lives, the water is just like the blood in the active body, protecting water is saving ourselves. Not to waste a single drop of water, otherwise, the only drop of water we could keep in the future would be our tear!My dear friends, mankind still faces a great difficulty in solving the problems of the environment and development, and there is a grand task to perform and along way to go. The middle school students in China will always cooperate with the young people of the world to protect the environment.The future is ours to build!Thanks for listening.Fudan Middle School Shanghai
