A Sentence from "Anna Karenina"

[Honore]

Dear Teacher,

The sentence "Do you suppose I could help knowing?" has been translated in the unabridged Turkish version of the subject book in the meaning "Do you think I do not know?".

Does the "can/could help gerund" structure always work similarly?

Anna Karenina : Part Two. : Chapter 3 by Leo Tolstoy @ Classic Reader (The tenth line from top)

It means that it was impossible for the person not to know to me.

dear teacher,

the sentence "do you suppose i could help knowing?" has been translated in the unabridged turkish version of the subject book in the meaning "do you think i do not know?".

it's not a good translation. (either the russian to turkish, or your turkish to english).
There is certainly a difference in meaning between:
"i knew it" and "i couldn't help knowing it"

does the "can/could help gerund" structure always work similarly?
the positive phrase " ... I could help <verb>ing" is not as common as the negative " ... I couldn't help <verbing>ing"

I agree, it probably should be "How could I not have known?"
