Tiếng Anh Chuyển đổi thì Hiện tại hoàn thành sang thì Quá khứ đơn

CHUYỂN ĐỔI THÌ HTHT SANG QKĐ​

A. Lý thuyết cách chuyển từ hiện tại hoàn thành sang quá khứ đơn và ngược lại

Dạng này có các mẫu sau đây:

Dạng 1. HTHT - HTHT

This is the first time I have seen him (đây là lần đầu tôi thấy anh ta)

=> I have never seen him before. (tôi chưa bao giờ thấy anh ta trước đây)

This is the first time I have eaten pizza

ð I have never eaten pizza before

Mẫu này có dạng:

Đây là lần đầu tiên.. làm chuyện đó

=>.. chưa bao giờ làm chuyện đó trước đây.

This is the first time + S + have/has + Vpt/ed + O: lần đầu tiên

ð S + have/ has + never + Vpt /ed + O before : Chưa bao giờ trước đây

Dạng 2. QKĐ - HTHT

Ex: I started / begun studying English 3 years ago. (tôi bắt đầu học Tiếng Anh cách đây 3 năm)

=> I have studied English for 3 years. (tôi học Tiếng Anh được 3 năm)

Ex: He started playing this game 3 years ago.

=>He has played this game for 3 years

Mẫu này có dạng:

S + started / begun + Ving + O + time ago

ð S + have / has + Vpt / ed + O + for + khoảng thời gian

.. bắt đầu làm gì đó cách đây + khoảng thời gian

=>.. đã làm chuyện đó for + khoảng thời gian

Note: Nếu không có ago mà có when + mệnh đề thì giữ nguyên mệnh đề chỉ đổi when thành since thôi

Ex: I started learnt English when I was 6 years old.

ð I have learnt English since I was 6 years old.

Dạng 3. QKĐ <=> HTHT

Ex: I last saw him when I was a student. (lần cuồi cùng tôi thấy anh ta là khi tôi là sinh viên)

=> I haven't seen him since I was a student. (tôi đã không thấy anh ta từ khi tôi là sinh viên)

Ex: I last ate this cake when I was 4 years

ð I haven't eaten this cake since I was 4 years

Mẫu này có dạng:

S + last + Vqk/ed + O + When + clause

ð S + have / has + not + Vpt/ed + O + since + clause

Lần cuối cùng làm chuyện đó là khi..

=>.. không làm chuyện đó từ khi..

Last: Lần cuối

Since: Từ khi

Dạng 4 .

Ex: The last time she went out with him was two years ago. (lần cuối cô ta đi chơi với anh ta cách đây 2 năm)

=> She hasn't gone out with him for two years. (cô ta đã không đi chơi với anh ta đã 2 năm nay)

The last time +S + Vqk/ed + O + was (time ago)

ð S + have / has + not + Vpt/ed + O + for time (khoảng thời gian)

Dạng 5 . It's ten years since I last met him. (đã 10 năm từ khi tôi gặp anh ta lần cuối)

=> I haven't met him for ten years. (tôi đã không gặp anh ta 10 năm rồi)

Mẫu này có dạng:

It's + khoảng thời gian + since + S + last + Vqk/ed + O

ð S + have / has + not + Vpt/ed + O + for + khoảng thời gian.

Đã.. khoảng thời gian từ khi làm gì đó lần cuối

=>.. không làm việc đó được + khoảng thời gian

Dạng 6 .

Ex: When did you buy it? (bạn đã mua nó khi nào)

=> How long have you bought? (bạn đã mua nó được bao lâu)

Mẫu này có dạng:

When + did + S + V nguyên thể + O?

ð How long + have / has + S + Vpt/ed + O?

When: Thì dùng quá khứ đơn

How long: Thì dùng hiện tại hoàn thành
