Bài tập Modal verb có đáp án
I. Lý thuyết cách làm Modal verb
1. Động từ khuyết thiếu – Modal verbs là gì?
Động từ khuyết thiếu (Modal Verbs) là loại động từ có chức năng bổ trợ nghĩa
cho động từ chính, không được sử dụng là động từ chính trong câu. Nó dùng
để diễn đạt khả năng, sự dự định, sự cấm đoán hay cả sự cần thiết… Động từ
khuyết thiếu đứng trước động từ chính ở dạng nguyên thể để bổ sung nghĩa cho động từ chính.
Một số động từ khuyết thiếu phổ biến như: have to, must, can, could, may,
might, should, ought to,… Cấu trúc:
(+) S + Modal verb (must/can/could/may/might/should,…) + V (nguyên thể) + O
(-) S + Modal verb (must/can/could/may/might/should,…) + not + V (nguyên thể) + O
(?) Modal verb (must/can/could/may/might/should,…) + S + V (nguyên thể) + O? Ví dụ:
- Linda can play volleyball very well. (Linda có thể chơi bóng chuyền rất giỏi.)
- You should finish your homework before going to the theatre. (Bạn nên hoàn
thành bài tập về nhà của mình trước khi đi xem phim.)
- Can you please get out of here? (Bạn làm ơn có thể ra khỏi đây không?)
- She has a fever. Tomorrow she would not go to school (Cô ấy đã bị sốt, ngày
mai chắc cô ấy sẽ không đi học được)
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: lOMoARcPSD|208 990 13
- 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.)
