Reference of pronoun it : "to read in English regularly" or "to read for pleasure"

Question

My question is what the first and the second pronoun "it" mean in the 2nd paragraph below. I think that the first it means "to read English regularly" or "to read for pleasure," and the second it also means either one. I'm still debating in my mind. When I think out the question in my own language, both options seem possible. Give me your advice. By the way, I understand the functions of the pronoun "it." Thank you.

One of the ways to improve your English is to read in English regularly. Spend some time in bookstores, reading a page or two of books that look interesting. You can also borrow books from the library. These days, I'm reading lots of English mystery stories to improve my English skills.

The point is to read for pleasure. Don't use a dictionary, because then it becomes studying and you'll grow tired of it. If you come across a word ...... (omitted below) .

Answer 1

It refers to "reading". The reference isn't restricted to any particular type of reading. It means "if you read with a dictionary then that reading with a dictionary becomes studying.

This can be confirmed since "reading for pleasure becomes studying" is an oxymoron and "reading regularly becomes a chore" doesn't make sense (if it means that irregular reading with a dictionary would not be studying.)

Answer 2

The word "it" refers to the previous sentence:

The point is to read for pleasure.

But the "reading for pleasure" is the "regular reading" that they recommend, so it doesn't make any difference. "It" refers to the sort of reading that they are talking about.
