論文答辯是展示你對論文主題的深入了解和專業(yè)知識的機會。通常，答辯會持續(xù)一至兩個小時，這取決于你的研究領(lǐng)域。首先你要陳述你的研究、發(fā)現(xiàn)和結(jié)論。完成陳述之后，委員會成員會問你一些問題，這些問題不僅基于你的陳述，還將基于你的書面論文。最后，委員會可能會批準(zhǔn)你的論文或者提出論文修改建議。我們總結(jié)了一些留學(xué)生論文答辯的常見問題，有需要的同學(xué)可以看一看喲。

1、你的研究是關(guān)于什么的？

你應(yīng)該用幾句話總結(jié)你的研究。這個問題很簡單，但需要專業(yè)技術(shù)知識來更好地解釋概念。例如，如果你完成了一篇論文，試圖解釋宇宙中暗物質(zhì)的組成和粒子加速器，你可以這樣設(shè)計你的答案：

In this research,the different aspects of dark matter and its detection models have been investigated. The cosmic ray positron excess observed by the pAMELA detector has been discussed and explained through the construction of models of decaying dark matter. The cosmic-ray electron and positron spectra were studied assuming a general Dirac structure for the four fermion contact interactions of interest. A supersymmetric leptophilic Higgs model was constructed to explain the possible excess of gamma rays in the galactic center. Finally,by the use of Razor analysis,an improvement on the dark matter collider searches is considered.

2、你為什么選擇這項研究？

這個問題要求你回答最初是什么激勵你選擇這項研究。你的答案可能會觸及到你對該研究領(lǐng)域的興趣。例如，如果你進行了一項名為“媒體戰(zhàn)爭：一戰(zhàn)與美國文化轉(zhuǎn)型”的研究，那么你可以這樣回答：

The First World War (1914-1918) has always been a topic of fascination for me,and my prime interest lies in exploring the state of society at that time. I wanted to analyze the formation of a nationalized,wartime cultural apparatus during the United States' involvement in the war and how theatre and music transformed the relationship between the government and American citizens.

3、你的研究范圍是什么？

你必須定義研究的邊界，并明確你所研究的內(nèi)容?？赡苌婕皫讉€要素，但必須定義你選擇研究的范圍。例如：

My study is on the efficacy of equity stocks in the US market. For my study,I have chosen 50 companies listed on the NASDAQ. You can review the names of these companies on page 5 of my thesis.

4、研究過程中，你的問題有什么變化嗎？如果有，如何實現(xiàn)？

通常，定性研究問題會隨著時間的推移而改變，這取決于你可能從焦點小組得到的回答?；蛘吣憧梢栽谧鰧嶒炇已芯炕蛞话阄谋狙芯繒r改變你的問題。你可以向評估委員會描述這一變化。例如：

We started our study to understand the impact of the new public policy change on recycling of vinyl waste through installation of garbage bins specifically for vinyl products. However,after interviewing some of the respondents in the target community,we found that the rule is actually irrelevant to their behavior and thoughts because the percentage of vinyl waste in that specific locality was very low and it didn’t need the installation of dedicated bins for the purpose. Going by their frustrations with the current economic insecurity,our study evolved into the impact of costs incurred by public policy changes.

同學(xué)可以參考上述示例來準(zhǔn)備自己的答辯答案。當(dāng)然，問題提出的形式會有所不同，但問題的核心通常是不變的。
