How do Chinese people use 的、地、得? 1、An adjective ends with 的 and is followed by a noun. 2、An adverb normally ends with 地 and is followed by a verb. 3、If you want to put an adverb behind the verb, you have to pick out 地 and replace it with 得, then put the 得 in front of the rest of this adverb. Hold on, there's also a tricky but easy way to remember the third tip. Just imagine how you change "careful (an adjective)" into "carefully (an adverb)"? That's right! 得 is like "ly" in some way, so, v. + 得 +adj. = adv. + v.

hello,Lucas 「的」in language of Chinese like "preposition" in English.We use the prep to limit verb.Also like "modifier". We put the Chinese word "得" into the sentence that behind the word"學".“學”is a verb. But,the sentence without the prep”得“ still kept in complete sentence. Like"他學很快" (He learns fast).It's fine. The example "別吃得太快" /"別吃太快" "她跑得很慢”/"她跑很慢" "我走得很遠"/"我走很遠" ..................... And the Question「大家好！''我·要·'' to know "为什·么'' the particle ''得'' is between ''他 学'' 和 ''很快'' in the following 句子: 他学得很快 (He learns fast). what is this particle's function?」 You can write down with Chinese. 「大家好！我想要知道為什麼“得”要放在“他學很快”的中間，句子是：他學得很快。(He learns fast)」 這個詞的作用是什麼？

well, it's like you have quick and quickly. We here use 的、得、地 (all three have the same pronunciation 'de') to define if it's an adjective or adverb. 很快地学会——quick is placed before learn, and it's used to describe learn ——choose 地. e.g. 疑惑地问、耐心地解答 学得很快——quick is placed behind learn, and it's used to describe learn —— choose 得 e.g. 这个问题问得很好、写得很漂亮 很快的学习者——quick learner. though quick is already an adjective, we still use 的 after it. and note, it's always a noun (or a phrase functioning like a noun) after this 的. 在中文里一般我们管这种短语叫“定中短语”，即定语修饰中心语，有adj.和n.两个部分，然而我们会把前两种使用‘“得”、“地”的情况，整体看做谓语。 BTW，出于习惯表达，前两种情况并非总能互换。

I have tried my best to figure it out!!! So first, "快" represents the meaning of "fast". However, it is neither an adverb nor an adjective. Just the meaning of "fast". In English, when you say "he learns fast", "fast" is an adverb. But "快” in Chinese is just the basic meaning of "fast". Again it is neither an adverb nor an adjective. The function of "得” is showing the extent of something. So, in this way, "快” can work like an adverb when you combine them together. When you read the sentence you may think like this: 他学得(he learns, like,.....)很快(really fast). He learns, like, really fast. Actually, in oral Chinese it is okay to say that without "得”。

I'm no expert, but I think it is required in order to turn a verb into a noun.
