2. The poet chose two groups of scenery to describe the period from the setting of the red sun to the rising of the new moon. The first two sentences are about the river at sunset. "A sunset is spreading in the water". The sunset shines on the river, but it means "spreading" instead of "taking pictures". This is because Sunset is close to the horizon and almost touches the ground. It really seems to be "paved" on the river, which is very vivid. The word "shop" is also gentle, which says the softness of autumn sunset, giving people a cordial and leisurely feeling. "Half the river is rustling, half the river is red", the weather is clear and windless, the river flows slowly, and there are tiny ripples on the river. The part that receives more light shows "red"; Where there is little light, there is dark blue. The poet grasped the two colors on the river, but showed the scene that the river was sparkling at dusk and the color changed rapidly in the sunset. The poet was intoxicated and put his happiness in the description of the scenery.
