Cảm nhận của anh/chị về vẻ đẹp hình tượng nhân vật Khách trong đoạn trích sau: “Khách có kẻ: Giương buồm giong gió chơi vơi, Lướt bể chơi trăng mải miết. Sớm gõ thuyền chừ Nguyên, Tương, Chiều lần thăm chừ Vũ Huyệt. Cửu Giang, Ngũ Hồ, Tam Ngô, Bách Việt, Nơi có người đi, đâu mà chẳng biết. Đầm Vân Mộng chứa vài trăm trong dạ cũng nhiều, Mà tráng chí bốn phương vẫn còn tha thiết. Bèn giữa dòng chừ buông chèo, Học Tử Trường chừ thú tiêu dao. Qua cửa Đại Than, ngược bến Đông Chiều, Đến sông Bạch Đằng thuyền bơi một chiều. Bát ngát sóng kình muôn dặm, Thướt tha đuôi trĩ một màu. Nước trời: một sắc, phong cảnh: ba thu, Bờ lau san sát, bến lách đìu hiu. Sông chìm giáo gãy, gò đầy xương khô, Buồn vì cảnh thảm, đứng lặng giờ lâu. Thương nỗi anh hùng đâu vắng tá, Tiếc thay dấu vết luống còn lưu!”
