#2. I am waiting for Bob to call me. He said he would call me at 3:00, and now it is 4:00. I say: "Bob still hasn't called me." Tom is Sally's ex-boyfriend. She told him to never call her again, but he continues to call her. Her friend says: "Tom hasn't still been calling you, has he? He has?! What a jerk!" We use "haven't still" much, much less often than "still haven't", and the two structures have different meanings.

2.I still haven't been able to learn English. definitely
