📖 LÝ THUYẾT
1. Was/Were là gì?
Was/Were là dạng QUÁ KHỨ của động từ TO BE (am/is/are).
So sánh:
| Hiện tại (Present) | Quá khứ (Past) |
|---|---|
| am | was |
| is | was |
| are | were |
Ví dụ:
- Hiện tại: I am happy. → Tôi vui.
- Quá khứ: I was happy. → Tôi đã vui.
💡 Cách nhớ: WAS/WERE = "đã là, đã ở" trong quá khứ
2. Cách chia Was/Were theo chủ ngữ
Quy tắc:
| Chủ ngữ | Động từ | Ví dụ |
|---|---|---|
| I | was | I was at home. |
| He | was | He was tired. |
| She | was | She was happy. |
| It | was | It was cold. |
| You | were | You were late. |
| We | were | We were students. |
| They | were | They were busy. |
📌 Quy tắc đơn giản:
I/He/She/It → WAS
You/We/They → WERE⭐ Lưu ý đặc biệt:
- YOU (bạn - số ít hoặc số nhiều) → luôn dùng WERE
- I (tôi) → dùng WAS
3. Câu khẳng định với Was/Were
🔸 Công thức:
S + was/were + ...Ví dụ:
| Câu | Tiếng Việt |
|---|---|
| I was at school yesterday. | Tôi đã ở trường hôm qua. |
| He was sick last week. | Anh ấy đã bị ốm tuần trước. |
| She was beautiful. | Cô ấy đã xinh đẹp. |
| It was hot yesterday. | Hôm qua trời nóng. |
| You were late. | Bạn đã đến muộn. |
| We were happy. | Chúng tôi đã vui. |
| They were students. | Họ đã là học sinh. |
4. Câu phủ định với Was/Were
🔸 Công thức:
S + was not/were not + ...Rút gọn:
- was not → wasn't /ˈwɒznt/
- were not → weren't /wɜːnt/
Ví dụ:
| Câu đầy đủ | Câu rút gọn | Tiếng Việt |
|---|---|---|
| I was not at home. | I wasn't at home. | Tôi đã không ở nhà. |
| He was not tired. | He wasn't tired. | Anh ấy đã không mệt. |
| She was not happy. | She wasn't happy. | Cô ấy đã không vui. |
| It was not cold. | It wasn't cold. | Trời đã không lạnh. |
| You were not late. | You weren't late. | Bạn đã không muộn. |
| We were not busy. | We weren't busy. | Chúng tôi đã không bận. |
| They were not students. | They weren't students. | Họ đã không phải là học sinh. |
💡 Trong hội thoại: Thường dùng dạng rút gọn (wasn't, weren't) vì nghe tự nhiên hơn.
5. Câu hỏi với Was/Were
🔸 Công thức:
Was/Were + S + ...?Cách tạo: Đảo was/were lên TRƯỚC chủ ngữ
Ví dụ:
| Câu khẳng định | Câu hỏi | Tiếng Việt |
|---|---|---|
| You were happy. | Were you happy? | Bạn đã vui không? |
| He was tired. | Was he tired? | Anh ấy đã mệt không? |
| They were students. | Were they students? | Họ đã là học sinh không? |
🔸 Cách trả lời:
Trả lời ngắn:
| Câu hỏi | Trả lời Yes | Trả lời No |
|---|---|---|
| Was he tired? | Yes, he was. | No, he wasn't. |
| Were you happy? | Yes, I was. | No, I wasn't. |
| Were they late? | Yes, they were. | No, they weren't. |
⚠️ Lưu ý: Trong câu trả lời ngắn:
