粉嫩的脸，红润的唇，矫健的膝并不是青春 。青春表现在意志的坚强与懦弱 。
想象的丰富与苍白、情感的充沛与贫乏等方面 。青春是生命深处清泉的喷涌 。
青春是追求 。只有当勇气盖过怯弱、进取压倒苟安之时，青春才存在 。
果如此，则60见之长者比20岁之少年更具青春活力 。仅仅岁月的流逝并不能使他们衰老 。
而一旦抛弃理想和信念，则垂垂老也 。岁月只能使皮肤起皱 。
而一旦丧失生活的激情，则连灵魂枯老，使人生枯如死水，毫无活力 。60岁长者也好，16岁少年也罢，每个人的内心深处都渴望奇迹，都如孩子一般眨着期待的双眼，期待着下一次，期待着生活的情趣，你我灵魂深处都有一座无线电中转站------只有你我年轻，则总能听到希望的呼唤，总能发出喜悦的欢呼，总能传达勇气的讯号，总能表现出青春的活力……… 一旦青春的天线倒下，你的灵魂即为玩世不恭之雪、悲观厌世之冰覆盖；即使你年方20.其实你已垂垂老也 。
而只要你青春的天线高高耸起，就可以随时接收到乐观的电波-----即使你年过八旬，行将就木，而你却仍然拥有青春，你仍然年轻 。2.珍爱生命之水 Cherish the water My dear Teachers,fellow students and friends: Good afternoon.I'm very glad to stand here and give you a short speech. today my topic is “Cherish the water ”.

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.
