They found Henry Adams, a poor American sailor who had landed in London by accident. One of the gentlemen said to Henry, “You mustn’t spend the note; you can only use it to prove your identity.” Henry was confused but nodded. He thought he would starve to death if no one accepted the note, but he had no choice but to try. The gentlemen told Henry that they would check on him in a month. When Henry walked into a restaurant, the waiter thought he was a beggar and wanted to drive him away. Henry took out the million-pound note, and the waiter’s attitude suddenly changed—he knew this man could not be a common beggar. He said, “Sir, you may sit wherever you like, and we will serve you the best food.” Henry realized that the note would bring him unexpected changes, but he still decided to keep his integrity. 1. 逐句分析情态动词含义与用法、过去将来时构成与语境 ① Two wealthy gentlemen made a bet about whether a man could survive with a million-pound banknote. ———情态动词could（表可能性，“能够”） 解析：could是can的过去式，此处用于宾语从句中，主句时态为过去时（made），从句用could表过去的可能性，说明打赌的核心是“一个人是否能靠百万英镑生存”。 ② You mustn’t spend the note; you can only use it to prove your identity. ———情态动词mustn’t（表义务，“禁止”）、can（表许可，“可以”） 解析：mustn’t强调“禁止花费钞票”的义务要求；can此处表许可，说明“只能用钞票证明身份”的限定条件，均符合两位绅士对亨利的规则设定。 ③ He thought he would starve to death if no one accepted the note... ———过去将来时would starve（构成：would+动词原形） 解析：主句谓语thought为过去时，宾语从句中用would starve表示“在亨利当时的认知中，未来可能发生的事”，即基于过去视角描述的未来动作，此处无明确计划，仅为单纯预测。 ④ The gentlemen told Henry that they would check on him in a month. ———过去将来时would check（构成：would+动词原形） 解析：主句时态为过去时（told），宾语从句中用would check表示“绅士们在过去承诺的、未来要做的事”，语气较正式，符合书面化叙述语境。 ⑤ ...he knew this man could not be a common beggar. ———情态动词could not（表可能性，“不可能”） 解析：could not是can not的过去式，此处用于宾语从句中，主句knew为过去时，表“服务员当时判断‘这个人不可能是普通乞丐’”，体现过去的否定推测。 ⑥ Sir, you may sit wherever you like... ———情态动词may（表许可，“可以”） 解析：may此处用于服务场景中，表对亨利的许可，语气礼貌，符合服务员态度转变后的语境。 ⑦ Henry realized that the note would bring him unexpected changes... ———过去将来时would bring（构成：would+动词原形） 解析：主句realized为过去时，宾语从句中用would bring表示“亨利当时意识到，钞票在未来会给他带来变化”，基于过去视角的单纯预测，无提前计划含义。 2. 核心词汇与固定搭配总结 ... ...
