关于下面做弊的，惩罚不是目的，教育才是目的。
可以写一段文字给团体全部。
I am grateful to be a member of this club. Every time I see you I see an assembly of extraordinarily talented, passionate, and aspiring youths. Down the road many years later, I can see many of you fulfiling your dreams, to become pillars of the society, creators of art or science, or even become leaders of the country.
In this respect, when you make such high level of achievements, every bit of your past will be scrutinized. A little mistake or error you make now without much thought may become a great liability to your future later.
I can not enumerate all the "little" mistakes you can make, just say, for example, putting exaggerated accomplishments in your resume, your website, or other forms of publicized personal information.
Just remember, there is nothing to gain by lying, and there is nothing to lose by telling the truth.
