Bài tập câu điều kiện loại 1 có đáp án

I. Lý thuyết nâng cao câu điều kiện loại 1

1. Định nghĩa

- Câu điều kiện là câu gồm hai phần: Một phần nêu lên điều kiện của hành động và một phần còn lại nêu kết quả của hành động đó, hay còn gọi là mệnh đề chỉ điều kiện (thường bắt đầu với if) và mệnh đề chính (chứa will/ would)

- Mệnh đề chỉ điều kiện thì luôn đi liền sau từ if

2. Cấu trúc

Ví dụ: If I have enough money, I will buy that flat (Nếu tôi có đủ tiền, tôi sẽ mua căn hộ kia)

Lưu ý:

- Mệnh đề “If” khi được đặt trước mệnh đề chính ta phải dùng dấu phẩy “,”

- Các động từ khuyết thiếu (can, may, should, must,…) có thể được dùng để thay thế “will” trong mệnh đề chính

- Đôi khi thì hiện tại đơn có thể được dùng trong mệnh đề chính, khi diễn tả một quy luật, một sự thật hiển nhiên, một điều kiện luôn luôn đúng

Ví dụ: If the sun doesn’t shine, you feel cold (Nếu mặt trời không tỏa nắng, bạn sẽ thấy lạnh)
