- Modal Perfect và cách dùng
- Để học và nhớ tiếng Anh, thì lý thuyết phải học thường xuyên và thực hành phải
diễn ra hằng ngày. Và bài viết này sẽ hướng dẫn các bạn cách sử dụng Modal
Perfect và bài tập ứng dụng đây.
1. Could, may, might + have + P2 = có lẽ đã
- Diễn đạt một điều gì đó có thể đã xảy ra hoặc có thể đúng ở quá khứ song người
nói không dám chắc.
VD:

(Tối qua, anh ấy có lẽ đã để quên vé cho buổi hòa nhạc.)
- I didn’t hear the telephone ring, I might have been sleeping at that time.
(Tôi đã không nghe thấy chương điện thoại, lúc đó có lẽ tôi đã ngủ.)
John might have gone to the movies yesterday.
(John có lẽ đã đi xem phim ngày hôm qua.)
- Diễn đạt điều gì đó có thể xảy ra nhưng đã không xảy ra
VD:

(Sao anh lại để nó đi về nhà một mình? Nó có thể đã bị lạc) → sự thật là nó không
bị lạc
2. Should + have + P2 = lẽ ra phải, lẽ ra nên
Chỉ một việc lẽ ra đã phải xảy ra trong quá khứ nhưng vì lí do nào đó lại không xảy
ra.

(Cảnh sát lẽ ra nên viết báo cáo về vụ cướp đó.) → nhưng họ đã không làm
Chúng ta cũng có thể dùng cụm từ was/were supposed to + V để thay cho should
+ have + P2

The policeman was supposed to make a report about the burglary.
3. Must + have + P2 = chắc là đã, hẳn là đã

(Nếu tôi có đủ tiền, tôi đã mua chiếc xe Honda ấy.)
