for the structure b, we often omit the verb (ofc and the 得)
so 你长得高 become 你高
for example,
- 你高吗？(r u tall?)
- 我高。(i am tall)
in fact, they should be like this:
- 你长得高吗？
- 我长得高。
as u see, we omit the verb 长.
for chinese, when we want to use many adjs to describe something, we usually use structure b.
because we want to express some kind of emotion. it means that we are shocked by its state------高（tall）、快（fast）、美丽（beautiful）etc
as we are expressing some kind of emotion, we almost always add 很（very） before the adv.
so u can find lots of structure b with 很 in chinese.
这座楼很高。-----这座楼（盖得）很高。
这个女人很美丽。---这个女人（长得）很美丽。
这辆车很快。---这辆车（跑得）很快。
天空很蓝。----天空（呈现得）很蓝。
so just remember this: when u want to describe a state of something, plz use structure b with omitting the verb: subject + (很) + adv.
grammatically, 很 is just an adv, we could use it or not. but in this structure, we could say: plz use it.----because u are expressing some kind of emotion, u want to highlight that kind of state.
