PHỤ LỤC: KIẾN THỨC TRỌNG TÂM
1. Câu điều kiện loại 1
Câu điều kiện loại 1 diễn tả một điều kiện có thể xảy ra ở hiện tại hoặc tương lai và kết quả có thể xảy ra nếu điều kiện đó được đáp ứng.
If + chủ ngữ + động từ ở hiện tại đơn, chủ ngữ + will/won’t + động từ nguyên mẫu.
Ví dụ: If we recycle paper, we will save trees.
Có thể đổi thứ tự hai mệnh đề:
We will save trees if we recycle paper.
2. Dạng phủ định trong mệnh đề điều kiện
Với động từ thường: if + chủ ngữ + don’t/doesn’t + động từ nguyên mẫu.
Ví dụ: If Nam doesn’t hurry, he will miss the bus.
Với động từ be: if + chủ ngữ + am not/isn’t/aren’t.
Ví dụ: If the weather isn’t good, we will stay at home.
3. Cấu trúc “unless”
Trong các bài tập trên, unless có nghĩa là “nếu không” và tương đương với if … not.
If you don’t water the plants, they will die.
Unless you water the plants, they will die.
Không thêm not vào mệnh đề sau unless khi chuyển đổi theo mẫu này.
4. Chuyển câu với “or” và “and”
Do …, or …: If you don’t do …, …
Hurry up, or you will miss the bus.
→ If you don’t hurry up, you will miss the bus.
Don’t do …, or …: If you do …, …
Don’t touch the pan, or you will burn your hand.
→ If you touch the pan, you will burn your hand.
Do …, and …: If you do …, …
Study hard, and you will make progress.
→ If you study hard, you will make progress.
5. Lưu ý
- Trong cấu trúc cơ bản của câu điều kiện loại 1, không dùng will trong mệnh đề chỉ điều kiện: If it rains, we will stay at home.
- Chú ý thêm -s/-es cho động từ hiện tại đơn khi chủ ngữ là he, she, it hoặc danh từ số ít.
- Sau doesn’t, động từ trở về dạng nguyên mẫu: If she doesn’t study …
- Khi viết lại câu, kiểm tra cả nghĩa, chủ ngữ, thì của động từ và dấu câu.
