1.Announcing the Beginning of the Speech Text表示presentation主体内容开始的语句

2.Shifting to the Next Main Point要点之间的过渡
Well, let's move on to the next point.
We will now come to the second problem.
Turning to the next question, I' 11 talk about the stages of the procedure.
As the second topic, I shall stop here. Now let' s turn our attention to the third topic.
So much for the methodology of our experiment. I would now like to shift to the discussion of the results.
Now, let's move away from the first part and switch over to the next part of my presentation.
That's all for the introduction and now we can go on to the literature review.
Next, I would like to turn to a more difficult problem.
The next point I'd like to talk about is the feasibility of this project.

Indicating the Points Briefly
Limited by the time available, I can only give you a very brief account of this matter.
I don't think that I should describe the methods in detail, because they are included in the handout.
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.
Let's go through the following points very rapidly.
I just want to outline for you what I experienced in using this new drug.
