1. $\text{When did you buy this house?}$

   $\text{We buy it three years ago.}$

   -> $\text{Câu hỏi quá khứ.}$

   $\text{( ? ) Wh- + did + S + V + O?}$

   $\text{S + V(ed) + O.}$

   -> $\text{ Lỗi sai là : buy.}$

   -> $\text{buy = bought.}$

   $\text{Vậy lỗi sai là C : buy -> bought.}$

   Trả lời
2. C -> bought

   – DHNB: three years ago -> quá khứ đơn.

   S+Ved/V2.

   (Wh)+did+S+V?

   – V bất quy tắc: buy – bought
