"How long have you lived in Korea?"
Today's class introduces a new structure that I personally find quite useful. Not only is it very useful, but one structure actually covers TWO different things.
The first I find useful because it's involved in questions that I hear quite often from people. The second I find useful because I find myself saying it to people more often, and often asking them questions using it. This might not make any sense just yet, but the videos'll explain more.
