The last time I went swimming when I was in France

`=>` I haven't gone swimming since I was in France

GT: Vì sau "the last time" là hoạt động "swimming" không còn diễn ra (như câu trên)

Vậy ta dùng "I haven't gone" (không đi bơi)

@Ryan

(The last time + S + Verb(ed/PI) +…+ was + mốc thời gian.
= S + have/ has + not + Verb(PII)+…+ since+ mốc thời gian.)

Đáp án : i haven't gone swimming was since i was in france.

Tạm dịch : Tôi đã không đi bơi kể từ khi tôi ở Pháp.
