1. Tóm tắt kiến thức lý thuyết Modal Verb

Modal verbs (động từ khuyết thiếu) là một nhóm động từ đặc biệt trong tiếng Anh không thể đứng một mình mà luôn đi kèm với một động từ chính ở dạng nguyên thể (bare infinitive) để bổ sung ý nghĩa cho câu. Các modal verbs thường được sử dụng để diễn đạt khả năng, sự cho phép, nghĩa vụ, lời khuyên, yêu cầu, dự đoán và mong muốn.

Ví dụ:

• She can play the piano well. (Cô ấy có thể chơi piano giỏi.) → Diễn tả khả năng.

• You must wear a seatbelt while driving. (Bạn phải thắt dây an toàn khi lái xe.) → Diễn tả nghĩa vụ.

Đặc điểm chung của modal verb:

• Không chia theo chủ ngữ (he, she, it…)
• Không có dạng "to" trước động từ nguyên mẫu đi sau nó (ngoại trừ "ought to" và "have to")
• Không có dạng phân từ hay nguyên thể có “to” (không có dạng "to can" hay "canned")
• Được theo sau bởi động từ nguyên mẫu không “to” (Ví dụ: can go, must study)

2. Lưu ý khi làm bài tập Modal verb

2.1. Hiểu rõ ý nghĩa của từng Modal Verb: Mỗi động từ khuyết thiếu có nhiều sắc thái ý nghĩa khác nhau, ví dụ:

Must có thể diễn tả sự bắt buộc hoặc suy luận chắc chắn 

• You must wear a uniform. – Bạn phải mặc đồng phục
• He must be at home now. – Anh ấy chắc hẳn đang ở nhà

Trong khi đó, can diễn đạt khả năng hoặc xin phép một điều gì đó:

• She can swim. – Cô ấy có thể bơi
• Can I go out? – Tôi có thể ra ngoài không?

2.2. Không chia Modal Verb theo thì hay ngôi: Không giống như động từ thường, modal verbs không có dạng quá khứ, tương lai hay phân từ. Chúng cũng không thay đổi theo chủ ngữ. Ví dụ:

• ĐÚNG: She can dance. / They can dance.
• SAI: She cans dance.

2.3. Modal Verb luôn đi kèm động từ nguyên mẫu (bare infinitive): Động từ sau modal verb luôn ở dạng nguyên thể không “to”, ngoại trừ một số trường hợp đặc biệt như ought to và have to.

• Cách dùng cấu trúc Should trong tiếng Anh và bài tập vận dụng

2.4. Sử dụng cấu trúc “modal verb + have + Vp2” để diễn tả quá khứ: Khi muốn nói về một sự việc đã xảy ra trong quá khứ với modal verbs, chúng ta dùng cấu trúc modal verb + have + past participle (Vp2). Ví dụ:

• She must have forgotten her keys. (Cô ấy chắc hẳn đã quên chìa khóa.)
• You should have studied more for the test. (Bạn đáng lẽ nên học nhiều hơn cho bài kiểm tra.)

2.5. Phủ định của một số Modal Verb có nghĩa khác với thể khẳng định: Một số modal verbs khi thêm “not” vào có nghĩa khác hoàn toàn so với thể khẳng định. Ví dụ:

• Must → Must not (mustn’t): Biểu thị sự cấm đoán (You mustn’t park here. – Bạn không được đỗ xe ở đây.)
• Can → Cannot (can’t): Biểu thị không thể làm gì đó (I can’t swim. – Tôi không thể bơi.)
• May → May not: Biểu thị khả năng không xảy ra (She may not come to the party. – Cô ấy có thể sẽ không đến bữa tiệc.)
