【详解】考查情态动词。句意：据说他们是从大陆游到岛上的，但他们不可能做到，因为中间的海洋太宽了。根据提示，表示“不可能做到”是过去发生的事情的推测，所以用can’t have done或者couldn’t have done，表示“过去不可能做过某事”，空处“不可能做到”应为can’t/couldn’t have done it/so/that/this，其中it/so/that/this作done的宾语。故填can’t/couldn’t have done it/so/that/this。
54．may have had a hand/might have had a hand/could have had a hand
【详解】考查动词时态。句意：巨石阵的国王很可能与这些石头有联系；他可能参与了纪念碑的规划，或者帮助运输和拉起石头。根据汉语提示“可能参与”，以及句子结构可知此处是句子谓语部分。表示“可能”可以使用may/might /could。表示“参与”可以使用have a hand in，根据句意此处表示“对过去发生的事情的推测”应使用情态动词+have done。故填may /might / could have had a hand。
55．shouldn’t have interrupted/oughtn’t to have interrupted
【详解】考查虚拟语气。句意：你不该打断会议来告诉我那件事，你本可以会后告诉我。分析句子结构可知，此处表示对过去含有责备语气，意为“本不该却做了某事”，可使用should /ought to have done固定结构。故填shouldn’t have interrupted/oughtn’t to have interrupted。

52．needn’t have taken
【详解】考查情态动词+have done。表示“本来不必做某事”短语为needn’t have done；表示“打车”用take taxi。故填needn’t have taken。
53．can’t have done it/can’t have done so/can’t have done that/can’t have done this/couldn’t have done it/couldn’t have done so/couldn’t have done that/couldn’t have done this
【详解】考查情态动词。句意：据说他们是从大陆游到岛上的，但他们不可能做到，因为中间的海洋太宽了。根据提示，表示“不可能做到”是过去发生的事情的推测，所以用can’t have done或者couldn’t have done，表示“过去不可能做过某事”，空处“不可能做到”应为can’t/couldn’t have done it/so/that/this，其中it/so/that/this作done的宾语。故填can’t/couldn’t have done it/so/that/this。
54．may have had a hand/might have had a hand/could have had a hand
【详解】考查动词时态。句意：巨石阵的国王很可能与这些石头有联系；他可能参与了纪念碑的规划，或者帮助运输和拉起石头。根据汉语提示“可能参与”，以及句子结构可知此处是句子谓语部分。表示“可能”可以使用may/might /could。表示“参与”可以使用have a hand in，根据句意此处表示“对过去发生的事情的推测”应使用情态动词+have done。故填may /might / could have had a hand。
55．shouldn’t have interrupted/oughtn’t to have interrupted
【详解】考查虚拟语气。句意：你不该打断会议来告诉我那件事，你本可以会后告诉我。分析句子结构可知，此处表示对过去含有责备语气，意为“本不该却做了某事”，可使用should /ought to have done固定结构。故填shouldn’t have interrupted/oughtn’t to have interrupted。
