Chào em, em chú ý câu số 4.
Theo cô, ở đây đề bài có 1 chút vấn đề, nếu như mệnh đề chính là she has to stay at home thì chúng ta phải dùng câu điều kiện loại 2 vì nó diễn tả 1 điều không có thật ở hiện tại/tương lai.
Tạm dịch: Lan phải làm rất nhiều bài tập về nhà, nên cô ấy đã phải ở nhà.
=> Nếu cô ấy không phải làm nhiều bài tập về nhà thì cô ấy sẽ không phải ở nhà (thực tế là ngược lại).
=> If Lan didn't have to do a lot of homework, she wouldn't have to stay at home.
