1. Lý thuyết: Dạng viết lại câu dùng if Cách nhận dạng: dựa vào các liên từ nối giữa 2 vế câu như: so, that’s why, because. Những mẹo làm bài nhanh trong trường không hiểu nghĩa hoàn toàn: + Nếu cả 2 vế trong câu sử dụng liên từ đều chia ở thì tương lai đơn thì ta dùng cấu trúc câu điều kiện loại 1 (chú ý không cần phủ định mệnh đề trong câu) + Nếu một vế thì hiện tại còn một vế ở thì tương lai hoặc hiện tại thì ta vẫn sử dung if loại 2 (chú ý lúc này ta cần phủ định lại mệnh đề trong câu) + Nếu 2 vế có một thì quá khứ thì ta dùng câu điều kiện loại 3 + Trong câu có các liên từ nếu phủ định rồi thi khi viết cấu trúc if ta bỏ “not” và ngược lại + Xuất hiện từ because ở vế nào ta thay thế bằng từ “if” ở vế đó. + Nếu xuất hiện các từ như: so hoặc that’s why thì ta để từ “if” ở vế còn lại trong câu.
