Giải thích:

Cấu trúc chuyển từ thì Quá khứ đơn sang thì Hiện tại hoàn thành ( và ngược lại ):

- S + started/ began + V-ing/ to-V + khoảng thời gian.

= S + have/ has + PII + since + khoảng thời gian/ for + khoảng thời gian.

- S + last + V(qkđ) + thời gian trong quá khứ.

= S + hasn't/ haven't + PII + since + mốc thời gian/ for + khoảng thời gian.

= The last time + S + V(qkđ) + was + thời gian trong quá khứ.

- S + have/ has + never + PII + before.

= This is the first time + S + have/ has + PII.

- S + haven't/ hasn't + PII + for + khoảng thời gian.

= It's + khoảng thời gian + since + S + last + V(qkđ).

- When did + S + V(inf) ?

= How long have / has + S + PII ?
