Take a concrete look at your reference topic. 1 is related to the study of network language, which is quite popular. If you need new words and materials in this field, I can send you the Language Situation in China published by the Language Situation Monitoring Center of Wuhan University last year, and you can choose from it. The application of network words in teaching Chinese as a foreign language is very new, because the teaching of new words is rarely mentioned, but it is necessary, so it has considerable value and can be further explored. We can focus on selecting some words that are close to life and have teaching significance for research. 2 is a very broad topic, which has been studied a lot and is suitable for comprehensive research, with little new ideas; 3 is an old topic. Compared with your other topics, this topic is less combined with teaching Chinese as a foreign language and can be ruled out. 4 it is broad, theoretical and easy to use, but it is not easy to write; "5" is actually a smaller topic of "3", which is similar to "Study on the Differences between Chinese and Foreign Color Words" and so on. This is also a kind of cultural study. If there is no accumulation of cultural psychology, it is recommended not to write, it is too vague. 6. "Good" as adverbial (e.g. "Hello ... (cruel)" as complement by Daiyu "Well played!" You can search how much research you have done and see your interests. This is a typical Chinese grammar research topic. 7 and 5 belong to the same type, so I won't go into details; 8, 3 and 5 are of the same type, with many nights of research and complicated contents, so it is not easy to do in-depth research; 9 is still the same (euphemism, politeness and appellation account for 5 of your 13 topics and belong to the scope of sociolinguistic research); There are quite a few studies on 10, which we have studied in the form of group discussion; 1 1 is also a cultural study. I have written about the cultural research of Wei, and this kind of research on famous things is also very complicated, which is not easy for beginners to write; 12 is a test of people's literary skills. If you look at it very shallowly, it must be a hard manual work with little effect to sum up your point of view by looking through books for examples. 13 is an irony, because it is traditionally believed that Chinese characters have great disadvantages compared with pinyin characters in information technology. If you think there is an advantage, it is absolutely reasonable. If you don't have a background in Chinese information processing, you'd better not talk.
Finally, I suggest that you divide the topics of 13 into several categories, and choose what you want to do according to your own interests, referring to the research difficulty obtained from various research status surveys and the expected results of each topic. When writing a paper for the first time, if you can't sort out your ideas, you can read the papers in this field online first (choose core journals such as Language Teaching and Research, World Chinese Teaching and Chinese Construction). Good luck with your writing!
