前言
現在即使是搞技術，做科研的，也需要在不同的場合，用ppt來做分享，做匯報，做總結。 如果國際會議，研討會，或者在外企，國外工作，英文的presentation就更加必不可少。英語的提升需要大家從聽說讀寫上一點點積累。
這里分享一些常用的承接句，希望對要做presentation有所幫助。
承接句主要有幾個作用：
1）開場，調節聽眾情緒。
2）過渡銜接不同部分內容
3）與觀眾互動，提升演講效果
4）當自己一下子蒙蔽的時候，給自己一些思考回憶的時間。
5）遇到一些突發情況下時救場
我們按照不同的作用來分別舉些例子
1）開場，調節聽眾情緒。
最簡單的，走上講台，平復下自己的情緒，然后說：Right, let's get started.
如果有人介紹你出場的，那感謝一下他或者chariman。 如果一般的場合 可以說 Hello everyone. 如果正式點可以 Hello， Ladies and gentleman
接着簡單介紹下自己，什么名字，職位，單位。
這個時候注意一定要和觀眾有眼神交流，保持微笑，拉近與觀眾的距離
進階：如果是比較輕松的場合，可以根據需要說下和報告或者和主辦方有關的有趣的經歷或者開個玩笑，或者做個小調查什么的，讓大家把注意力集中到台上。
Before I start my speech, let me ask you a question. By showing of hands，how ……？
也可以注意下細節，比如問下話筒聲音是否夠
Can you hear me all right? Is my voice too loud?
2）過渡銜接不同部分內容
整體內容和目錄
除非是對整體演講的節奏非常有把握，或者是一些時間有限制, 比如5分鍾之內的演講，可以不用概述整體內容外，最好有一個outline，讓大家能夠明白今天你要說哪些內容，各部分的主題是什么。
比較簡單的，Today I am going to give a presentation on…. / The purpose of this presentation is to...
I am going to start with a general overview and then focus on …(…in general,… more particularly).
there are five main aspects to this topic (...the first, ... the second, ...a third, ...another, ... the final).
引出下一部分內容
let's move on.
We will now come to the second problem
As the second section, I shall stop here. Now let' s turn our attention to the third section.
Next, I would like to turn to a more difficult problem.
返回之間講的內容
Let' s come back to what I said in the first part of my speech
At this point, I would like to refer again to the question of methods in the first part of my lecture.
要開始講具體的方法時
I think this part is the most difficult, so I'll explain it in greater detail.
I think this part of my paper is most important, so I plan to spend more time on it.
想跳過某個具體的方法時
Limited by the time available, I can only give you a very brief account of this matter/I will not go into detail on it.
This point has been talked about repeatedly in this symposium, so I am not going to spend too much time on it.
總結內容
We've discussed many points today. Let me quickly summarize the principal points:
Before we end, let me briefly recap what we have discussed here today.
Let’s look at what I have talked about.
To summarize, I have talked about three aspects
結束時
Thank you all very much for taking the time to listen to this presentation. Now, if you have any questions, I'd be happy to answer them.
Thank you for your attention.
3）與觀眾互動，提升演講效果
相比較國內的報告，國外的報告提問會比較頻繁。有些時候甚至直接打斷來提問的，所以需要有所准備。
如果想充分交流的，鼓勵大家提問的，那一開始可以說，Please feel free to interrupt me at any time.
如果不想報告被打斷，呢可以先和聽眾說好，If you have any questions, I will be pleased to answer them at the end of the presentation.
如果已經有人問了，那就說，Sorry, Please can you save your questions till the end.
或者這個問題你之后會提到，現在就不說了 that's a very good point. I will be coming to that point in a minute.
如果這個問題不好回答，可以先打下預防針
That's a tricky question.
I am afraid there's no easy answer to that one...
如果一部分講完，像讓聽眾提一些問題
So，before next section, let's throw it open to questions
希望讓聽眾注意PPT或者別的內容時，可以說
As you can see from this graph representing ...
If you could just take a look at ...
This curve in this slide shows
This table on this slide presents
This figure in this slide exhibits
This diagram on this slide depicts
但不要每張PPT都聽眾看，平時他們的注意力還是應該在你和你的語言上。
4）當自己一下子蒙蔽的時候，給自己一些思考回憶的時間
被提問題時，如果一下子沒有聽清楚
I beg your pardon, I didn't catch what you said.
I'm sorry I forgot your first question. Would you be so kind as to say it again?
If I understand you correctly, you are saying/asking
如果想給自己留幾秒時間思考一下，可以先簡單評價下問題
This is a very good question/I appreciate that question
This is a big question/Let me try to answer your questions one by one
Thank you for that question. This is a challenging question and I'm afraid I can only provide a partial answer to it. Anyway, I'll try my best to answer it.
如果有個東西感覺一下子解釋不清楚了，想調整一下，想給自己一些的時間
What I meant to say was
Perhaps I'm not making myself clear…，Let me put this another way
5）遇到一些突發情況下時救場
一不小心，口誤了，一般情況可以直接說sorry，excuse me 然后更正，比如
The population is 13 million, sorry, 31 million.
As you can see from the first row, excuse me, the second row
或者重新說一遍，I mean ……
如果PPT上的圖或者文字看不清，可以要求要關下燈
Could we have the lights off?
The slide is not so clear. Please darken the room a little more.
實在不行，解釋一下讓觀眾理解
I apologize that this slide is not so clear, but I hope you can still make out the general idea
別人幫忙點PPT，需要下一頁或者上一頁
Now, we can go on to the next slide
Next, please
Let's go back. No, not this one. One back. Back one more.
May we have the previous slide again?
時間到了還有幾頁沒講完
Time is up，so Let's go through the following slides rapidly/let's come to the last slide directly.
Sorry, I see the red light is shining so I have to skip the last part and jump to the conclusion
希望以上的總結可以給大家一個最基本的框架，知道各個情況下可以說些什么。 如果有任何補充或者有錯誤需要修改，歡迎留言一同探討。
