Then I have to ask seriously: what's the subtle differences between the first and the third meanings, please?
It is admittedly a
very subtle difference; in fact, re-reading Richard’s post, I must admit I’m not too sure myself what difference he was trying to get at. My best guess is:
‘I don't usually read books, but having read one recently, I read a book this month.’ — Usually, I don’t read books. Recently, I read a book (presumably for the first time in a while). This month, I read another.
‘I don't usually read books, but I have read books. I read a book this month.’ — Usually, I don’t read books. However, in the past I have read books. This month, I read another book for the first time in a while.
