When I saw this sentence, there seems to be something weird to me. I got this sentence from Oxford Learner’s Dictionaries, entry number 17.
I haven't got very far with the book I'm reading.
'Got' means 'to arrive', by the way
Firstly, why does this clause use forming of present perfect?
Second, Does this sentence need the expression of 'very far'?
I don't know exact meaning of it.
