高频搭配：confirm that + 从句（证实：confirm that the information is accurate = 证实信息准确）；confirm a booking / reservation / appointment（确认预订/预约）；confirm sb.'s fears / doubts / suspicions（证实某人的担忧/疑虑/怀疑）；await / seek confirmation（等待/寻求确认）；confirmation of（…的确认：confirmation of the diagnosis = 诊断的确认）；confirmed（adj.）（已确认的；根深蒂固的：a confirmed alcoholic = 酗酒成性的人；a confirmed bachelor = 坚定的独身主义者）；辨析：confirm（证实已知或怀疑的事）vs. verify（核实，通过检查验证：verify the data = 核实数据；比 confirm 更强调主动检查过程）vs. affirm（肯定，声明：affirm one's commitment = 肯定承诺；比 confirm 更强调正式声明，不一定有新证据）。
陷阱
⚠️confirm（证实已有信息）vs. affirm（积极声明/肯定）——侧重不同

✗
confirm = affirm（完全等同，可互换）
✓
confirm（证实：laboratory results confirm = 实验室结果证实了某个已有的怀疑/初步结论；有具体证据支撑）；affirm（正式声明，肯定：affirm one's commitment to = 肯定对…的承诺；不一定有新证据，侧重主动表态）；此句 confirmed the initial diagnosis = 实验室结果为初步诊断提供了证据，用 confirm 正确；若用 affirm，则表示医生「宣称/强调诊断」，语义不同
confirmconfirm（确认/证实：confirm that the information is correct = 证实信息正确；重在「提供证据使之成为确定事实」）verifyverify（核实，验证：verify the accuracy of the data = 核实数据准确性；比 confirm 更强调通过主动检查、测试来验证，过程更明确）
