(AI giải đề cho tôi)
Câu 30: 'Tom last visited his hometown ten years ago' = lần cuối Tom về quê là 10 năm trước, tức là từ đó đến nay Tom chưa về quê nữa. Cấu trúc tương đương: S + last + V2(ed) + ... + time ago = S + haven't/hasn't + V3(ed) + ... + for + time. Do đó câu đúng là 'Tom hasn't visited his hometown for ten years.' A sai vì 'didn't visit... for ten years' mang nghĩa quá khứ đơn, không nhấn mạnh việc kéo dài đến hiện tại; B sai nghĩa (bắt đầu thăm quê 10 năm trước); C sai nghĩa (đã về quê suốt 10 năm). Đáp án D khớp với đáp án nguồn (30. D).
