“Kẻ bạc mệnh này, duyên phận hẩm hiu, chồng con rẫy bỏ, điều đâu bay buộc, tiếng chịu nhuốc nhơ, thần sông có linh xin ngài chứng giám. Thiếp nếu đoan trang giữ tiết, trinh bạch gìn lòng, vào nước xin làm ngọc Mị Nương, xuống đất xin làm cỏ Ngu mĩ. Nhược bằng lòng chim dạ cá, lừa chồng dối con, dưới xin làm mồi cho cá tôm, trên xin làm cơm cho diều quạ, và xin chịu khắp mọi người phỉ nhổ.” 1. Những từ xưng hô được in đậm trong đoạn văn trên có cùng chỉ một người không? Đó là ai? 2. Các câu trong đoạn văn trên liên kết với nhau bằng phép liên kết nào? 3.
