选择题
When Miss Smith asked me a few questions in class yesterday, my mind happened to be wandering. As a result, I had to give her awful ____________ responses.
A．offbeat
B．off-line

考查词语辨析。Offbeat不寻常的，off-line 脱机的，offhand 唐突的，无准备的，off-key走调的，不和谐的，句意：昨天当Miss Smith要求我课上回答问题的时候，我碰巧在走神，结果，我给了他一个糟糕的唐突的反应。故选C。
