Dear teacher,
As I do english exercise,I do not understand the answer key.Can you please help me?
"hey,look where you are going."
"Oh, I am terribly sorry_____ "
A I am noticing
B I was not noticing
C I have not noticed
D I do not notice
The answer is "B" but I do not understand why we do not choose D.My friends said that "notice" is never in present progressive tense.Is it right?
