Why is 很早 after the verb in 我起床很早? I came across the following sentence:



今天我起床很早。
Jīntiān wǒ qǐchuáng hěn zǎo.
Today I wake up very early.



I am confused about 很早 appearing after the verb. I think here 很早 (very early) indicates the time of the action, so I would expect to follow the structure Time + Subject + Verb:



今天很早我起床。



Otherwise, I could also understand 很早 as a degree complement, and follow the following the structure Subj + Verb + Object + Verb + 得 + Complement:



今天我起床起得很早。



Why sentence 1. is correct?
I'd take 今天我起床很早 as the shorthand of 今天我起床起得很早.
To me, 今天我起床很早 isn't my favourite sentence.  The succinct version doesn't necessarily mean &quot;more idiomatic&quot;. Some grammar pedants might even frown at 今天我起床很早 because they might take issue with the omission.
Personally, I usually say: 我今天起得很早，我今天很早就起床了 or 我今天一大早就起床了.
