易错句子She tried to reason her son about his plan.
正确表达She tried to reason with her son about his plan.
reason 作“以理相劝、说服”讲时是不及物动词，必须与介词 with 连用，构成 reason with sb（与某人讲道理）；不能直接接人作宾语。汉语“劝某人”后面直接跟宾语，学习者容易漏掉 with。

正确表达Careless driving causes many accidents.
reason 作动词只表示“推理、论证、讲道理”，不表示“导致、引起”；要表达“造成某结果”须用 cause。汉语里“原因/理由”都常对应 reason，学习者容易把名词义硬搬成动词，但 reason 没有“造成”这一动词义。

reason 表示“推理、思考”时通常作不及物动词，涉及思考的对象要加介词 about，即 reason about sth；不能直接把思考对象放在动词后面作宾语。
argue 侧重表达对立观点或发生争吵，也可指“主张”某一观点；reason 侧重按逻辑推演得出结论，或表示“以理劝说”（reason with sb）。两者都可译作“辩论”，但 argue 常含情绪对立，而 reason 强调理性推理。
deduce 强调从已知事实经演绎推出具体结论，较正式，多见于逻辑或侦探语境；reason 含义更宽，既可指一般思考推断，也可指劝说或辩论。
persuade 指成功说服某人去做某事，常接 into 或 out of；reason 表示“说服”时强调讲道理，常与 with 连用（reason with sb），并不一定表示说服成功。
