1. 一般过去时：“studied”、“covered”、“enjoyed”、“had”等一般过去时的使用适合描述与学习地理相关的过去经历和活动。 2. 关系从句：“which made the learning experience more engaging”是一个关系从句，为实地考察提供了额外信息，增强了对学习体验的描述。

1.现在完成时：“I've taken it upon myself to learn geography” 现在完成时的使用表示一个从过去开始并持续到现在的动作，显示了学习过程的持续性。 2.不定式的使用：“to explore different places” 这里不定式的使用表明使用在线资源和应用程序的目的。

1.现在完成时态：“I haven't formally studied geography.” 这里使用现在完成时态表示说话者直到现在都没有正式学习过地理。 2.比较结构：“rather than having a deep geographical knowledge” 该结构用于比较两种不同的导航方法，表达偏好。
