Ladies and gentlemen，
As is known to us all， we used to have a very nice world， in which birds were singing [and]（1）trees were whispering. Looking into the limpid（清澈的）river， we could see the reflection [reflections]（2）of our smiling faces But my dear friends， have you ever noticed the changes around us？ Have you ever noticed that the limpid rivers have become stinking ditches （臭水溝） instead？ I could swear （發(fā)誓） that I rarely see birds nowadays， even a common sparrow. So shouldn't we do something？ Shouldn't we try our best to heal this world and make it a better place for us to live in？
I don't know much about environmental science， nor can I offer any suggestion. What I can do is try my bit to protect ourenvironment.
I plant trees， as I know we still have many barrens （荒地），and sands are swallowing our land every day. Trees can protect the soil from eroding （遭侵蝕）。 Besides， trees can beautify our cities and the environment.
Planting trees is obviously a good way to protect the environment， but surely that is not enough. Besides planting trees， I always pay attention to keeping the surroundings clean. I never step on the （3） lawns and I never spit in the （4） wrong places. I always leave rubbish into the （5） dustbins. Whenever I see anybody damaging the environment， I will tell them to stop it. For example， I will ask them to pick up the rubbish and throw it into dustbins.
Here I'd like to take this opportunity to advise the gentlemen present today to stop smoking. Smoking does harm not only to your own health but to the people around you. When you blow a puff of （一口） smoke into the air do you know how many cubicliters of clean air you have polluted？ Save the clean air for yourself， for your children， and for your children's children. So gentlemen， stop polluting our environment. I have successfully persuaded （說服） my father to give up smoking. I believe you， distinguished（尊敬的）gentlemen， can make it as well. In this way， you and I can really play a role in the environmental protection.
Although I have done only a little bit， I know what I have done does mean something. One flower doesn't make a spring. So ladies and gentlemen， in order to have a clean， beautiful and harmonious（和諧的）world for yourself， for your family， and for your fellow citizens， will you please join me in doing our bit to protect our environment？
Thank you！

這是一篇寫得相當不錯的演講稿。盡管有些說法有點過頭，不夠自然，如開頭第一段，另外，在勸說人們放棄吸煙時，口氣還不夠委婉。但總體而言，無論從文章結(jié)構(gòu)，還是詞語的運用，都反映出作者不俗的英語功底。特別是文章較好地體現(xiàn)了演講的一些修辭特點，如：設問、排比等等，同時還融進了一些幽默，起到了調(diào)節(jié)聽眾情緒的作用。某些語言上的不足之處點評修改如下：
（1）這里加上and為好。
（2）reflection 表示“倒影”時，是可數(shù)名詞。根據(jù)上下文，這里用復數(shù)為好。
（3）、（4）、（5）根據(jù)上下文，這里均是泛指，還是不用定冠詞the顯得自然。
