)核心用法对比
特别提醒
could 表示过去的能力时，通常指过去泛指的、长期拥有的能力。若要表示“过去某次能够成功做成某事”，通常使用 was/were able to。
例：After hours of effort, they were able to put out the fire. (不能用could)
回答以 Could you... 开头的委婉请求时，不可用 "Yes, I could."，而应用 "Yes, I can." 或 "Sure." 等，因为请求是针对现在行为的。
中考常考考点
语境辨析：在单项选择或完形填空中，根据时间状语（如now, last year）或上下文语境，判断使用表示“能力/许可”的 can 还是 could。
委婉程度：在情景对话中，考查 Could you... 比 Can you... 更礼貌、正式，是高频考点。
否定意义：考查 can't 表示“不可能”的推测意义，以及对 Can I... 的否定回答 No, you can't。
时态区分：在完成句子或句型转换中，考查 could 与 was/were able to 在表示“过去具体某次成功做到”时的区别。
