This podcast episode focuses on clarifying the usage of past simple versus past progressive tenses in English. The hosts begin by defining each tense and providing examples, then address the common confusion surrounding their use with activities that take time (e.g., running, hiking, skiing). Their key takeaway is that past progressive is used for general activities ("I went running"), while past simple is used when specifying the activity ("I ran a marathon"). The hosts illustrate this with numerous examples and a role-play, aiming to improve listeners' fluency and confidence in using these tenses correctly in conversation. A second part of the episode, focusing on interrupted actions, is promised.
