 CHUYÊN ĐỀ 18: CÂU HỎI ĐUÔI
A. RULES
 CÔNG THỨC CHUNG
 S + V + .., trợ từ + S?
 Nếu câu nói trước dấu phẩy là câu khẳng định, câu hỏi đuôi phải ở thể phủ định (viết tắt).
 Nếu câu nói trước dấu phẩy là câu phủ định, câu hỏi đuôi phải ở thể khẳng định.
Ví dụ:
 You haven't finished the work, have you? (Bạn chưa xong việc phải không?)
 You have finished the work, haven't you? (Bạn xong việc rồi phải không?)
 Câu hỏi đuôi của “I am” là “aren’t I”
 Câu hỏi đuôi của “Let’s” là “shall we”
 LET đầu câu:
  "Let" trong câu xin phép (let us/let me)
 thì khi thành lập hỏi đuôi sẽ dùng “will you?"
 MỘT SỐ  “Let” trong câu đề nghị giúp người khác (let me) 
 thì khi thành lập hỏi đuôi sẽ dùng "may I?"
 TRƯỜNG 
 HỢP CẦN 
 LƯU Ý Chủ ngữ là "Everyone/Everybody, Someone/ 
 Somebody, Anyone/Anybody, No one/ Nobody..." 
 câu hỏi đuôi là "they"
 Chủ ngữ là "nothing, everything, something, anything" 
 thì câu hỏi đuôi dùng "it"
 Trong câu có các trạng từ phủ định và bán phủ định 
 như: never, seldom, hardly, scarcely, little...
 thì câu đó được xem như là câu phủ định - phần hỏi 
 đuôi sẽ ở dạng khẳng định  Câu đầu có MUST: Must có nhiều cách dùng cho nên tuỳ theo cách dùng mà sẽ 
 có câu hỏi đuôi khác nhau:
 a. "Must" chỉ sự cần thiết thì khi thành lập hỏi đuôi ta dùng "needn't"
 Ví dụ: They must study hard, needn't they?
 b. "Must" chỉ sự cấm đoán thì khi thành lập hỏi đuôi ta dùng "must"
 Ví dụ: You mustn't come late, must you?
 c. “Must” chỉ sự dự đoán ở hiện tại thì khi thành lập hỏi đuôi ta dựa vào động 
 từ theo sau must.
 Ví dụ: He must be a very intelligent student, isn't he?
 d. “Must" chỉ sự dự đoán ở quá khứ (trong công thức must + have + Vp2) thì 
 NHỮNG khi thành lập hỏi đuôi ta dùng have/has căn cứ theo chủ ngữ của câu.
TRƯỜNG Ví dụ: You must have stolen my bike, haven't you?
 HỢP  Câu đầu có I + các động từ sau: think, believe, suppose, figure, assume, 
 CẦN fancy, imagine, reckon, expect, seem, feel that + mệnh đề phụ:
 LƯU Ý + Lấy mệnh đề phụ làm câu hỏi đuôi.
 Ví dụ: I think he will come here, won't he?
 I don’t believe Mary can do it, can she?
 + Cùng mẫu này nhưng nếu chủ từ không phải là “I” thì lại dùng mệnh đề chính đầu 
 làm câu hỏi đuôi.
 Ví dụ: She thinks he will come, doesn’t she?
  NEED vừa làm động từ thường, vừa làm động từ khuyết thiếu, nên:
 + Nếu "need" là động từ thường thì khi thành lập hỏi đuôi ta phải mượn trợ động từ.
 Ví dụ: She needs to water the flowers in the morning, doesn't she? 
 + Nếu "need" là động từ khuyết thiếu thì khi thành lập hỏi đuôi ta dùng luôn need.
 Ví dụ: I need do it by myself, needn’t I?
