Giải thích

Đáp án: A

Kiến thức: Đảo ngữ với “Not until”

Nghĩa câu gốc: Chúng tối đến sân bay. Chúng tôi nhận thấy hộ chiếu của chúng tôi vẫn ở nhà.

Cấu trúc câu:

Not until S + V + auxiliary + S + V (inf).

Đáp án B sai thì “…our passports are still at home”.

Đáp án C sai cấu trúc, đảo ngữ với “not until” chỉ thực hiện ở vế sau.

Đáp án D sai cấu trúc: It was NOT until…that S + V.

Đáp án D còn sai cả thì của động từ “realize”, cần chia thì quá khứ
