do they both mean "He walks slowly?" yeah 形容词（代词）+的+名词（如：蓝蓝的天空） 动词+得+形容词 （如：飞快地跑） 形容词+地+动词 （如：跳得高） 这里有一组含有“的”、“地”、“得”的例句如下： 1. 蔚蓝色的海洋，波涛汹涌，无边无际。 2. 向日葵在微风中向我们轻轻地点头微笑。 3. 小明在海安儿童公园玩得很开心。

I think you can think of 的, 得, 地 as suffixes that indicate parts of speech. Basically, 的 is used after a noun or an adjective, 得 after a verb, and 地 after an adverb. Unlike 的 and 得, which have their root in Chinese history, the idea of 地 used as an adverb indicator is relatively new; it was borrowed from western languages. It's probably intended to imitate the -ly ending in English. When you use the “adv 地 V” structure, it describes one single action and that's it, and the verb is normally followed by a particle or/and an adverb when the verb has only one character. Take for example the first sentence in your question, an particle of 著 or an adverb of 開 or 掉 should be added to the verb 走 so that the sentence would sound natural and complete. When you use the “V 得 adv” structure, you are making a conclusion or stating how you feel about the action described. I don't know if a little literal translation will help better, but I'll try anyway. The original meaning of 得 is “to get”. Therefore, a word-for-word translation of 他走得很慢 is “He:他 walk:走 (and) get:得 (a result of being) very slow:很慢”. The result or conclusion of him being very slow is quite subjective. Therefore, the “adv 地 V” structure is a “cold” statement, like it's made by a biologist observing an animal. While the “V 得 adv” structure is a “warm” statement, it shows how the speaker subjectively feels. Here are other examples: (雨: rain; 很猛: fiercely; 落: fall; 下: down) 雨很猛地落下。 → The speaker is making an objective observation of how the rain falls/fell. And the verb 落 is followed by an adverb, which is 下 in this case, to make the sentence sound more natural and more complete. It's a “cold” sentence. 雨落得很猛。 → The speaker is describing how he personally feels/felt about the way the rain falls/fell. The rain makes/made him think so. It's a “warm” sentence. PS There's an official plan to integrate 的, 得, 地 into one, which is 的, but I don't think it's settled already.

verb+得+adj adj+地+verb

形容词后+地；动词后+得

语法上的东西我就不重复了。 不过你大可必仅仅拘于语法上来理解“得”和“地”，从他们所处的语境去理解也很重要。 如“他很慢地走”just shows that the man is walking slowly without emotional judge. But "他走得很慢" means more than that,maybe including the speaker's emotion of complain or explaination ect.According to my understanding LOL
