Does the logic in this paragraph make sense to you? THX~ “She mows the lawn.” The key to understanding this sentence lies in the time taken for mowing a lawn. Mowing a lawn obviously takes longer than articulating this sentence does. So, the sentence cannot mean that “She is mowing the lawn,” but perhaps “Usually, it is she who mows the lawn rather than some others.” In other words, “She mows the lawn” does not refer to any single one action but a pattern of activity. An example distinct from this one is “She promises to mow the lawn.” Articulating this sentence takes more or less the same time as the act of making a promise itself. In this sense, “She promises to mow the lawn” indicates a particular act of making a promise. Probably, it should be revised as “She promised to mow the lawn,” which appears to be more natural in tense.
