Understanding: These two sentences are an inseparable whole. The poet is not standing somewhere on the shore overlooking Tianmen Mountain, but his foothold is a "lone sail" coming from Japan. The word "Chu" brings dynamic beauty to the originally static mountain zone. Facing the Tianmen Mountain in Jiajiang, it seems to be coming towards you.
Looking at the mountains is like welcoming them. Looking at the mountains carefully is a boat tour. -Anonymous "Huanxisha, the five poles are flat"
Understanding: The object of study is that the mountain is moving and the position between the mountain and the ship has changed, so the ship is chosen as the reference.
Choosing the ground as a reference, the relative position between the mountain and the ground has not changed, so the mountain does not move.
Early in the morning, I bid farewell to Jiangling city, which is high into the sky, thousands of miles away, and the boat is only one day away. -Li Bai's "The First Delivery of Baidicheng"
Understanding: The word "Caiyun" describes the high terrain of Baidicheng, which is the dynamic momentum for the whole article to describe the fast walking of underwater boats. "A thousand miles" and "a day" are in sharp contrast with the remoteness of space and the brevity of time.
Lie down and watch the clouds move. I don't know whether the cloud and I are both in the East. -Chen's "Xiang Zhong"
Understanding: The author knows that the ship moves very fast. If the "cloud" in the sky really doesn't move, it should be like the "elm dike" and keep moving backwards when lying and watching. Then, the author suddenly realized that the clouds in the sky, like himself, are eastward. "Cloud and I" remain relatively static, which embodies the relativity of motion and stillness.
The endless trees are rustling leaves, and the Yangtze River is rolling unpredictably. -Du Fu's "Ascending the Mountain"
Understanding: "Endless" and "inexhaustible" make "rustling" and "rolling" more vivid, which not only reminds people of the rustling of fallen trees and the surging Yangtze River, but also invisibly conveys the feeling that youth is fleeting and ambition is hard to pay.
On the high cliff, it seems to be thousands of feet high, which makes people think that the Milky Way has fallen from heaven to earth. -Li Bai's Looking at Lushan Waterfall
Understanding: the word "fly" vividly describes the scene of the waterfall spewing out; "Straight down" not only describes the steep slope of the mountain, but also indicates the urgency of the water flow. The sky is falling and unstoppable. The towering incense burner peak is hidden in the clouds. Looking at the waterfall in the distance is like flying down from the clouds and falling in the sky, which naturally associates with a galaxy falling from the sky.
On one side of the boat, Qian Fan races; At the head of the sick tree, every year is a spring shower. -Liu Yuxi's "Yangzhou First Meeting to Enjoy Lotte"
Understanding: This sentence is a description of relative motion. The lake is still, only the boat is moving. On the side of the sunken ship, Qian Fan is competing; Before a sick tree, everything is spring.
Sitting on the ground, traveling 80 thousand miles a day, watching the sky and thousands of rivers. -Mao Zedong's "Seven Laws and Two Songs, Send athel Loren"
Understanding: If a person sits motionless somewhere on the surface of the earth, he will also travel 80,000 miles a day with the rotation and revolution of the earth and see 1000 rivers in the distance. Although relative to the earth, people's spatial position has not changed, and people are relatively static; However, compared with the wider space, such as the solar system, the spatial position of human beings has changed, which is a great spatial movement, reflecting the unity of absoluteness and static relativity of movement.
The cries of apes on both sides of the strait are still unconsciously crowing in their ears, and the canoe has passed the heavy green hills. -Li Bai's "The First Delivery of Baidicheng"
Understanding: In an instant, the "canoe" has passed the "Chung Shan Man". In order to describe the speed of the ship, the poet added the word "light" to the ship itself in addition to the ape sound and the mountain shadow.
You look at me, I look at you, and there are only my eyes and Jingting Mountain's eyes. -Li Bai's Sitting Alone in Jingting Mountain
Understanding: The poet personifies Jingting Mountain. Although the bird flew away, the poet didn't go back, and he didn't want to go back. He stared at the quiet and beautiful Jingting Mountain for a long time and felt that Jingting Mountain seemed to be looking at himself affectionately. There is no need to say anything between them, and they have reached emotional communication.
