The 16 Tenses
4 Times × 4 Aspects = 16 tenses
Build and deconstruct verb forms
Two Dimensions
时 ≠ 态
Tense = Time × Aspect — 两个独立维度交叉组合
时 TIME — 什么时候？
Present 现在 — 此刻
Past 过去 — 已过去
Future 将来 — 尚未来
Past Future 过去将来 — 站在过去看将来
态 ASPECT — 什么状态？
Simple 一般 — 事实、习惯
Progressive 进行 — 正在持续
Perfect 完成 — 已完成，有影响
Perfect Progressive 完成进行 — 持续到某时
4 × 4 = 16 种组合 — 这就是英语全部的时态
