2 Đặc điểm của động từ khuyết thiếu

Do không mang đầy đủ chức năng và tính chất của động từ thường, khi sử dụng các động từ khuyết thiếu chúng ta cần lưu ý những điểm sau đây

Không phải chia theo các ngôi số ít hay số nhiều

Các động từ khuyết thiếu không phải chia theo các ngôi số ít hay số nhiều, chỉ sử dụng ở hai thời điểm đó là hiện tại và quá khứ

Dạng của hiện tại: may, should, can, will, ought to, had better

Dạng của quá khứ: might, should, could, would, ought to, had better

Ví dụ:

- My brother can speak French fluently (Anh trai của tôi có thể nói tiếng Pháp thành thạo.)

- We could go out if it didn’t rain (Chúng tôi đã có thể ra ngoài đi chơi nếu mà trời không mưa.)

Không có dạng nguyên mẫu, không có “to” hay các dạng phân từ khác.

Thay vì được sử dụng cho tất cả các thì như động từ thường, động từ khuyết thiếu không có dạng nguyên mẫu, không có “to” hay bất kỳ dạng phân từ nào khác

Ví dụ:

- Linda can dance very beautifully (Linda có thể nhảy rất đẹp.)

- Bill will go to Cat Ba tomorrow (Bill sẽ đi Cát Bà vào ngày mai.)

Không cần trợ động từ đi kèm trong câu hỏi Yes/No hoặc câu hỏi có vấn từ

Ví dụ:

A: Can you swim? (Bạn có thể bơi không?)

B: Yes, I can (Tôi có thể.)

Có cách dùng tương đối như một trợ động từ trong câu

Động từ khuyết thiếu đứng trước động từ chính và bổ nghĩa cho động từ đó, vì vậy chúng mang cách dùng tương tự như một trợ động từ

Ví dụ:

- I will go to Sam Son beach next Sunday (Tôi sẽ đi tới biển Sầm Sơn vào chủ nhật tới đây.)

- I won’t go to Sam Son beach next Sunday (Tôi sẽ không đi tới biển Sầm Sơn vào chủ nhật tới đây.)
