As you _______ the hotel, you will see a lake.
B. Are approaching
C. Will approach
D. Would approach
I honestly don't understand. The answer sheet says that since there's the word "as" here, the answer is "are approaching". Can you explain it a bit further? I just don't get it. "approach" seems equally correct to me. And I didn't eliminate the other 2 answers because although they seem less sensible to me, I still don't know why they would be incorrect. They just seem weird to me.
