oral presentation开头怎么说

Good morning,everyone. Today, we are going to talk about ...

Good M/A/E everyone.Thanks for your time to be here ...I am here presenting ...

first you should make the following clearly:
* What will they know of your subject?
* What background information do you need to provide?
* What technical terms or complex matters will you need to explain and what can you assume they already know?
* How can you keep them interested?
* What questions might they ask?
* Will your presentation be marked? If so, what are the marking criteria?
开头
Good morning/afternoon/evening Ladies and Gentlemen,

'I'm going to talk about ....' or
'This morning I want to explain ....' or
'The points I will focus on are first of all..... Then...... This will lead to..... And finally...'

关于什么样的演讲？其实开头根据内容也可以有好多种……
1楼的是比较普通的
2楼则是比较正式的，外加晚宴之类的……
