-By the end of this presentation you will know all there is to know about.
结尾
结束语有这样几种比较精彩的选择：
-Finally.
-By way of conclusion.
-In conclusion,I'd like to.
-I'd like to finish by.
-I hope Ih***e made myself understood
-I hope this has given you some idea/clear idea/an outline of.
-Let me end by saying thanks.
-That,then was all Ihad to say on me
-I hope I've managed to give you aclearer picture of me.

如何回答问题
另外在阐述完自己的观点和看法之后可能也会接受考官的一些问题.考官会问：may I ask you some questions?或者I want to ask you some questions,ok?
这个时候我们也可以适当发挥一些，以达到和别人不同，给考官留下深刻印象的目的.
所以你可以这样回答：
-I will be pleased to answer any questions you may h***e at the end of the presentation.
-If you h***e any questions,I will be pleased to answer them at the end of the presentation.
-Please feel free to interrupt me at any time.
-Please stop me if you h***e any questions.
-I will be coming to that point in aminute.
-Yes,that's ***ery good point.
这些开头和结尾的万能句型，相信一定能够轻松搞定面试的口语部分，这样有新颖的开头，有条理的主体，加上最后的总结，一定能让您的presentation与众不同。
