I am having some difficulties understanding the differences in meaning between the following structures (the examples are from Line dictionary):
Verb + Adj
e.g:
走快了她会累。
Zŏu kuài le tā huì lĕi.
Walking quickly tires her.
Adj + Verb
e.g:
我们快走。
Wŏmen kuài zŏu.
Let's go!
Verb + 得 + Adj
e.g:
你的表走得快,还是走得慢?
Nĭ de biăo zŏudékuài,háishì zŏudémàn?
Does your watch gain or lose?
Adj + 地 + Verb
e.g:
一个打杂的很快地走过来了。
Yīgè dăzá de hĕnkuài dì zŏu guòlái le.
Very soon a cleaner marched over.
I know this topic has been asked partially (except structures 1. and 2.) in:
Difference in MEANING (NOT structure) between 得 vs 地
