I'm starting to become aware of a weakness in my Chinese grammar. While in my speaking and writing I'm generally grammatically correct (of course, not always), I don't often use more sophisticated grammatical structures (which is particularly relevant in writing); I'm thinking things like:
随着时间的推移,……。
……对于……至关重要。
……在……中扮演着不可或缺的角色。
The resources I'm aware of, like the Chinese Grammar Wiki generally take a bottom-down approach, and analyze individual words. However, I'm more interested in improving my knowledge of such structures from the top down, i.e., studying not just individual words, but jointly with their collocations.
I'm interested in both finding resources where I can study more sophisticated grammar structures, and learning about methods for studying them.
Question: How can I improve the sophistication of my Chinese grammar usage?
