Take my words with a grain of salt. I did Chinese SL (not SLA) last year and am only a mid range student. I'll just do what I can.
Hi! I am doing 关羽 as my topic! (I am doing second language normal)
I have done a 1 minute introduction and decided on my 3 aspects. But I am stuck. Help please?
两位考官,你们好!今年我们学习的题目是中国的历史人物,我选择的小题目是关公。我研究了以下几个方面, 1. 关公的生平, 2. 关公的主要功绩,3.关公生中的过失,4. 人们对关公的评价。为了这个研究,我阅读了罗贯中的《三国演义》,听了观看了纪录片《易中天品三国》中所有有关关公的片段。You have said listened to a documentary, which really does not make sense. 除此之外,我也看了许多网上质料。这就是我研究的大概情况。
You will need to thank the examiners in the end. Since you said 考官 at the start, refer to your examiners as teachers and say 谢谢老师.
Note: I haven't actually read the materials
There will be four question that will be asked of you when doing any detailed study these are. I will write them in English as they could be worded in a number of ways:
1. Why did you choose this topic as your detailed study?
2. Have you encountered any difficulties during your detailed study? Wen answering this question, please explain how you have overcomed this difficulty as well.
3. Which of the resources above was the most useful to you? You will need to look at the materials to determine their usefulness.
4. What have you gained from doing your detailed study?
You will need to consider them. These are generally applied to all of detailed study in CSL. (which is why you should choose a detailed study you are really passionate about).
I hope this helps. Again, I will take CatherineMo2015's advice as it is rather difficult to give specific help over an online forum. If not, get a tutor. Mine really helped me when I was doing Chinese last year.
