在国际会议上做好口头报告的必备环节(question time)

如果你的论文在国际会议上发表，你又做 oral presentation, 那么如何回答问题也是需要技巧的。一会高质量的会议还是有些牛人云集的，口头报告既可以让别人有机会认识你，探讨一些学术问题，也有利于认识牛人呀：）

所以在这整理了如何完美的完成question time，希望对大家有帮助：）

Question time

几点简要事项：

※Welcome the question

※Listen carefully to the question---don’t interrupt

※Take time to think before you answer

※Check you have understood the question---rephrase or clarify if necessary ※Reply positively---be brief and clear

※Accept criticism positively

※After your answer, check that the questioner is satisfied

如果遇到了以下的情形，看看如何来Handling it

1. Instead of asking a question, the person strongly, rather angrily, disagrees with your point of view.

―――― 对于这种情况你就先礼貌地听他讲完，然后重述一下你的观点，如果有必要，重述时加上点佐证。

如果这人还是不依不扰，you can say, “Well, we’ll have to agree to disagree on this point,” or “ Unfortunately, there’s no time to go into this more deeply right now.”

2. Instead of asking a question, the person states his or her own viewpoints that agree with yours.

You can say, “ Yes, that fits in exactly with what I was saying”.

3. The person states positively that some information you have given is inaccurate, but you are absolutely sure that you are correct.

这里，你可以提供你的information source or provide additional support for your statement.

OR YOU CAN SAY, “ I believe that my information is correct, but I will certainly recheck my facts.”

4. 如果有人直接提出你的一些information is inaccurate, 而你又不能自己的information was correct or not.

―――Do not feel threatened or regard this as an attack.

YOU CAN SAY, “ I appreciate your bringing this to my attention. I’ll have to recheck my sources to see what is correct.”

5. 如果有人问的问题 is so basic, 你发现他 did not understand any of your presentation.

YOU CAN SAY, “ Well, I don’t think we have time to discuss that point right now, but I’ll be happy to talk with you about it later.”

6. The person asks a question that will require a very long, complicated, or technical answer.

不要把时间都用在解释一个问题。

YOU CAN SAY, “That’s an interesting question, but it would take much too long to answer it adequately. Perhaps we can discuss it later.”

7. 如果有人问的问题与你讲的完全无关

YOU CAN SAY, “That’s an interesting question, but my presentation doesn’t really deal with that issue,” or “ I’m afraid I don’t see how that question applies to what I’ve said.”

8. 如果有人问的太多，占了别人的机会。

YOU CAN SAY, “I’m very pleased by your interest, but perhaps we should give others a chance to ask a few questions. I hope we can talk in more detail later.”

以下是一些具体的例句，可以在回答问题的时候用上

Answering Questions

☆☆Delaying Answering/ Playing for Time

Well, let me see??

Actually,??

Let me think for a moment. Ah, yes, ??

I’m glad you asked that question.

You’ve raised an important point here.

☆☆Avoiding Answering

That’s a good question but, unfortunately, it’s beyond the scope of this presentation. Later, I could perhaps point you in the direction of some useful websites that might help you.

I’m afraid I’m not really in a position to answer that.

I’m afraid I don’t have the figures on me. Perhaps I could E.mail them to you later.

☆☆Adding information

Let me add,??

In addition, ??

☆☆Referring back

As I said before,??

As I mentioned before,??

☆☆Clarifying/ Restating

What I was trying to say was??

I mean that??

To point it another way??

In other words??

☆☆Clarifying the meaning of a question

So what you’re asking is ??

If I understand the question correctly, you would like to know?? When you say??, do you mean??

☆☆Checking the questioner is satisfied

Does that answer your question?

Is that OK?

The Draft of Academic Presentation

国际会议的口头报告模板，每页ppt你需要讲什么东西需要分页详细写，尽量口语化，如下是本人参加比利时会议的模板，供大家参考。 P1

开场白：

I am so honored to be with you to communicate academic questions and ideas.

The tile of my academic presentation is “The preparation and catalytic performance of porous silica nanotube functioned with heteroatoms”

I shall only take ten minutes of your time.

I will talk about the topic on the preparation of porous materials.

P2

First of all, i wanna introduce myself. I come from nanjing university of technology, nanjing city, china.

P3

The content is listed as follows.

P4

All our researches are conducted by the academic thoughts. Generally speaking, we are committed to porous materials. In order to explore high-performance functionalized materials for Pilot experiments and scale-up production; we tune the structure, such as composition and morphology step by step and optimize them further. What’s more, the possible synthesis mechanisms are also investigated. Today, the presentation is based on the right-hand branch.

P5

It is known that mesoporous silica have excellent characters as the catalyst carrier, such as……..

But due to lack of active sites, we have to introduce organic or inorganic species as active sites. And the catalytic performance need to be further improved.

P6

As we know, the three factors including activity, scale and diffusion factor play decisive role in the catalysis, affecting the yield, selectivity, stability strongly. In our presentation, we mainly focus on the influence of scale factor on the catalysis.

P7

Due to lack of active sites for mesoporous silica, two main methods (surface loading, modified framework) are widely reported, by which various organic or inorganic active sites can be immobilized on the surface or incorporated into the framework of mesopoous silica.

P8

Though various morphologies of mesoporos silica were widely synthesized, the synthesis of the mesoporos silica, with three simultaneous characteristics including doped metal, mesoporous structure and specific morphology, is always a challenge, which is rarely reported.

In other words, for our case exploring a proper condition, at which the silicon and metal sources can simultaneously hydrolyze, can ensure a desired material.

P9

Next, let’s look at the synthetic steps. Firstly,…. Then, …. After that, …. At last, we obtained the

products.

P10

In this work, by changing the synthesis conditions, such as …, and so on, the pure mesoporous silica with different morphologies were synthesized, including nanosphere, nanorod, helix, capsule and nanotube. We will focus on the preparation and catalytic application of mesoporous silica with nanotube morphology.

P11

the SEM images of samples: A1, A2, A3 are shown in the figure. It can be seen that sample a1 is nanowire-like with length of about 2μm and diameter of about 100nm. When the amount of ... is 0.04 g, the morphology of sample A2 became to be short and thick rods and the size is about 1μm in length and 400nm in diameter, respectively. With further increasing the amount of ..., the sample A3 and A4 turned to be spherical morphology. It also can be seen that the diameters of samples A3 and A4 are substantially the same about 450nm. However, the spherical morphology of A4 is more regular than that of A3.

The XRD patterns showed four reflection peaks attributed to (100), (110), (200) and (210), respectively, due to the hexagonal sructure.

P12

Then, we keep the same amount of ..., increasing the amount of ....

We found that the length increased gradually. The XRD patterns also showed the hexagonal sructure of samples B1, B2, B3, B4.

P13

Moreover, an additional proof of the hexagonal symmetry structure is given by TEM and the FT pattern. The N2 adsorption-desorption isotherms of the samples B1, B2, B3, B4 exhibit a typical type-IV isotherm.

According to the table of structural parameters, we can find that the specific surface area and total pore volume increase gradually, the thickness of wall decrease and there is no obvious change in diameter.

P14

Furthermore, the possible synthesis mechanism of the mesoporous silica nanotube in dual templates system was proposed. We suggest that due to electrostatic repulsion between positively charged ammonium ions from hydrated ammonia molecules and hydrophilic groups of ..., especially in ammonia (NH3, 25wt.%) solution, the high concentrated ammonium ions provide a crowded and repulsive space to prevent the conjunction of ... molecules, leading to the formation of the rod-like micelles as template to form pore structure instead of sphere-like ones.The role of co-template ... is suggested to tune the length of rod-like micelles by arranging itself along the axis of channel with PEO and PPO part immersed in the hydrophilic and the hydrophobic group of CTA+ respectively. As a result, the mesoporous nanotube with different length will be synthesized. However, the non-polar ... micelles are not affected by positively charged ammonium. When the amount of co-template increased further, the non-polar ... micelles tend to control the morphology of micelles which are sequentially from nanotube, short rod to sphere-like ones. It my be the reason that the non-polar ... micelles would provide stronger attractive force than the electrostatic repulsion derived from the PEO block, ammonium ions and head group of ..., respectively.

P15

In order to investigate the influence of the morphology and structure of mesoporous silica on catalytic

performance, the samples with copper incorporated were synthesized.

P16

The figure shows the SEM and TEM images of samples a1, a2, a3, from which we can see they represent incremental length in the range of about 0.5, 1.0 and 1.5μm, and insignificant change in diameter around 100nm. In XRD patterns, there are also four reflection peaks for the samples with copper incorprated, respectively, which indicates the incorporation of the inorganic copper salt has no obvious effect on the hexagonal sructure and the ordered degree of pore structure. Moreover, the trends in length and the diameter of nanotube are illustrated.

P17

The N2 adsorption-desorption isotherms of the samples a1, a2, a3 exhibit a typical type-IV isotherm according to the IUPAC classification and no hysteresis loop at the relative pressure range of 0.2≤p/p0≤0.4, implying the samples not only have ordered mesoporous structure but also the uniform pore size. Moreover, the pore diameters did not change significantly at different weight ratio of .../.... The most probable pore sizes of samples a1, a2, a3 are determined to be 2.71, 2.50, 2.44 nm, respectively. The structural parameters are listed in following table.

P18

This table summarized the catalytic activity of copper-modified porous silica nanotube in the direct hydroxylation of benzene with H2O2 as oxidant. The catalysts showed high catalytic activity, and direct proportional relationship between the benzene conversion and the length of the silica nanotube. Considering the similar copper content determined by ICP, the variations of catalytic activities were probably caused by different retention time of reagent in the nanotube with different lengths. P19
