1. since --> for (a long time là khoảng thời gian)
2. This is the ... time đi với HTHT (visited --> have visited)
3. has built --> has been built (bị động)
4. finish --> finished
5. haven't came --> haven't come (come-came-come)
6. who --> which (which thay thể cho đại từ chỉ vật)
7. didn't use --> haven't used
Bởi vì có since nên dùng HTHT
8. had taken --> took (After + QKHT, QKĐ)
P/S: Lần sau bạn nên chép lại đề nhé !
