+ Dùng thành ngữ dân gian, so sánh ngang bằng: Động tác thả sào và rút sào nhanh như cắt; hình ảnh con người như một pho tượng đồng đúc...
+ Dùng hình ảnh cường điệu: dượng Hương Thư " giống như một hiệp sĩ của Trường Sơn oai linh hùng vĩ " gợi sự liên tưởng tới những hình ảnh huyền thoại anh hùng xưa với tầm vóc và sức mạnh phi thường của những Đam San, Xinh Nhã bằng xương bằng thịt đang hiển hiện trước mắt người đọc, nhằm khắc họa nổi bật và tôn vinh sức mạnh của con người nhằm chế ngự thiên nhiên.
* Ngoài ra, cách so sánh này còn đối lập mạnh mẽ với một hình ảnh " dượng Hương Thư ở nhà, ăn nói nhỏ nhẹ, nhu mì, ai gọi cũng vâng vâng dạ dạ "
- Qua đó tác giả khẳng định một phẩm chất đáng quý của người lao động: Khiêm tốn, nhu mì đến nhút nhát trong cuộc sống đời thường, nhưng lại dũng mãnh, nhanh nhẹn, quyết liệt trong công việc, khó khăn, thử thách.

Xét hiệu P-1= \(\dfrac{4\sqrt{x}+4}{x+2\sqrt{x}+4}-1\)
= \(\dfrac{4\sqrt{x}+4-x-2\sqrt{x}-5}{x+2\sqrt{x}+5}=\dfrac{-x+2\sqrt{x}-1}{x+2\sqrt{x}+1+4}\)
= \(\dfrac{-\left(\sqrt{x}-1\right)^2}{\left(\sqrt{x}+1\right)^2+4}\)
Ta luôn có:
\(-\left(\sqrt{x}-1\right)^2\le0\)với mọi x>0 (1)
\(\left(\sqrt{x}+1\right)^2\ge0\) với mọi x
\(\Rightarrow\left(\sqrt{x}+1\right)^2+4>0\) với mọi x (2)
Từ (1) và(2) \(\Rightarrow\dfrac{-\left(\sqrt{x}-1\right)^2}{\left(\sqrt{x}+1\right)^2+4}\le0\) với mọi x
\(\Leftrightarrow P-1\le0\Leftrightarrow P\le1\)
Vậy...
