28.I don’t think what he said is _____ to the topic we are discussing . He has missed the point.
句意：我认为他所说的和我们今天讨论的话题无关。他没有抓住要点。A项“忠实的，忠诚的”；B项“与……平行”；C项“和……相关”；D项“和……相似”。be relevant to“和……相关”。故选C项。
从后面He has missed the point “他已经偏离要点”可知what he said “他所说的”跟the topic we are discussing“我们正在讨论的话题”不相关，所以选C。
未看全题目就容易错选D
