是…的
Emphasizes the circumstances (when, where, how, with whom) of a past event
HSK 2HSK 3.0 · 2
S + (是) + time/place/manner/doer + V + 的 (+ O)
Use 是…的 when both speakers know an event has ALREADY happened and the focus is on its details: 你是什么时候来的? – 我是上个月来的. The emphasized element goes between 是 and the verb. 是 may be dropped in affirmative sentences, but the negative must be 不是…的. The object may follow 的 (我是在网上买的票). Do not use 了 inside 是…的: say 我是昨天到的, not *我是昨天到了的.
