Bạn tự làm àk Hay bạn sao chép mô đây.

Nếu có thì cho mk link vs 

Mà có chắc là đúng ko đây ?

Mình tự làm à nhe

Mới đầu mình tưởng viết lại với mệnh đề nguyên nhân kết quả(becasue,since,as,so therefore,...)

Nhưng về sau mình lại nghĩ về câu điều kiện

Có : S + V(hiện tại) ,so S + V(hiện tại)

=>If S + didn't V ,S + wouldn't V

Because S + V(hiện tại) , S + V(hiện tại)

=>If S + didn't V ,S + wouldn't V

Lưu ý:khi because ,so viết sang if thì cần lùi thì và đổi khẳng định sang phủ định và ngược lại

Muốn biết thêm rõ thì nên google
