谢邀，首先说写的问题。如果你具备了英语思维，那就容易的多，所谓英语思维就是写作时不想汉语，没汉语什么事儿，直接用英文构思。而不是用汉语构思，再译成英语。

至于说写的时候要注意什么，那就看人家要求你讲什么，和对演讲风格有什么要求。比如有的演讲比赛要求选手能以平和自然的方式进行演讲，有的可能要求幽默风趣一点，

没有什么常用词可言，只不过是开头一两句的套话，诸如，it is a great pleasure for me to make a speech here.这些东西在网上或相关书籍里都能找到，这里不多说。

说道举例，本人不才，去年一个学生要求我帮她写一个演讲稿。她要参加一个著名英语报主办的演讲比赛。她获得了二等奖，这孩子很优秀，本该得第一名，但第一名被某市市长的千金拿走，据说两人只差一分。因为第一名可获得自主招生考试的加分。不说了，都是眼泪。

这里我节选一部分，仅供参考，献丑了。

Ladies and Gentlemen:

I am honored to be here to share my feelings with you.

In fact, we can see two extremes in the issue, the most creative, like those great scientists, and the least creative. Most of us are something in between. A convenient example is my mother. Certainly she is not a great scientist (in my heart, she is equally great). She is a little creative, especially when she is in the kitchen. All these years she tries her best to raise me to be a healthy and not too stupid person. She puts her heart on how to make meals both delicious and nutritious, and here I am, the result of her experiments in her kitchen laboratory. So the real situation is that most people are like her. They go through our educational system and are still a little creative in life.

So my conclusion is that schools do not kill students’ creativity. On the contrary, they give us the essential knowledge and skill on which our creativity can be based.

That’s all.
