G2 English K200 tense and aspect do more than place events in past, present or future. They show whether an event is complete, ongoing, repeated, earlier than another event, or still relevant at a reference time. Those distinctions can change chronology, inference and paraphrase.
This one-hundred-and-twenty-fifth Learner’s Guide develops tense–aspect control. It extends Vol 0117 Reference-Frame Control and Vol 0093 Causal-Language Control.
The tense–aspect audit
Identify event time, reference time and whether the event is viewed as complete, ongoing, repeated or prior. Then ask whether a paraphrase preserves those relations. A change from “had left” to “left”, or “has worked” to “worked”, can alter the timeline.
