The sentence 我吃饭的时候看了一本书。 apparently has two verbs (吃 and 看), but I can’t see how the two actions are correlated. Could anyone explain that?
“我吃饭的时候” has an adverbial clause (I'm not sure if you can understand that). When 我吃的的时候，我看了一本书.
I read a book while having dinner.
You can see 吃 as an adverbial clause of time.
