Could you look why this is unnatural?
They said that 1 should be corrected into 2.
1. If I knew I would live in the U.S., I would've studied English harder.
2. If I knew I would be living in the U.S., I would've studied English harder.
I get the feeling that 'living in a place' takes some time, and that's why you need to use
continuous aspect, but I'm not sure of it. Or is it because 'be + V-ing' means some scheduled event in the future?
Also, I was wondering why 1 sounds unnatural to natives.
