Accelerator Day 1 – Tense Frame Shifts

Rationale: This Accelerator series helps Thai EFL high-intermediate learners move beyond the intermediate plateau toward advanced proficiency. Day 1 focuses on tense frame control: when English narrates past events, when it analyzes general meaning in the present, and how academic writing often shifts between the two. The design combines grammar, vocabulary, paraphrasing, and inference so learners develop accuracy, meaning control, and academic judgment together.
