Dấu hiệu nhận biết
- Yesterday
- Last (night, week…)
- Khoảng thời gian + ago
- Thời gian trong quá khứ. Ví dụ: 2 weeks ago; In 1945
Cách sử dụng
1. Diễn tả 1 hành động, sự việc đã xảy ra trong quá khứ, không liên quan đến hiện tại và tương lai.
- He worked at McDonald’s.
2. Sử dụng trong câu điều kiện If, đưa ra giả thuyết và câu mong ước. Ví dụ:
- He could get a new job if he really tried.
- I would always help someone who really needed help.
- I wish it wasn’t so cold.
3. Có thể sử dụng quá khứ đơn ở hiện tại khi muốn thể hiện sự lịch thiệp.
- I just hoped you would be able to help me.
Quy tắc cấu tạo V-ed (Chỉ áp dụng với động từ có quy tắc)
- Thông thường => động từ+ ED (ví dụ: want => wanted)
- Kết thúc bằng E => động từ + D (ví dụ: => d)
- Kết thúc bằng phụ âm + Y => đổi thành I + ED (ví dụ: fly => flied)
- Kết thúc bằng nguyên âm + Y => động từ + ED (ví dụ: play => played)
- Động từ 1 âm tiết kết thúc bằng 1 phụ âm, trước nó là 1 nguyên âm => nhân đôi phụ âm cuối và + ED (ví dụ: refer => referred)
- Động từ 2 âm tiết, trọng âm rơi vào âm tiết thứ 2, kết thúc bằng 1 phụ âm, trước nó là 1 nguyên âm => nhân đôi phụ âm cuối và + ED (ví dụ: prefer => preferred)
Chú ý:
- Visit => Visited
- Listen => Listened
- Open => Opened
- Enter => Entered
Thì quá khứ đơn (Past simple) dùng để diễn tả hành động sự vật đã xảy ra trong quá khứ hoặc vừa mới kết thúc.
Ví dụ:
- We went shopping yesterday.
- He didn’t come to school last week.
