1．—I think you must be very interested in the subject we are discussing.
—Not at all.________，I feel it rather boring.
A．In contrast B．On the other hand
C．On the contrary D．In a word
解析：考查插入语的用法。句意：“我想你肯定对我们讨论的话题非常感兴趣。”“一点也不。相反，我觉得这话题相当无聊。”on the contrary“恰恰相 反”，用来表示完全不赞成对方刚说过的观点，符合句子的语境。in contrast
