How can you run to the far north? " Young Boise stood on the snow-white ice like an angel of fifteen or sixteen. His whole body seems to be born for this world of ice and snow, clean and pure, and the broken light of diamonds shines all over him. -Combined with the environment Eg2: Her small body stood in front of the huge lux lion, raised her head and looked at it naively: "Do you want to die?" Her voice was weak and calm, as if asking someone if they had breakfast. Combined action Eg3: The little girl frowned seriously, shook her head, and said seriously, "No, I didn't come to rob you of your ice." Then she turned her eyes to the window. It was dark and the bloody sunset was completely extinguished. The dark night covered every inch of the town, leaving only sporadic lights in the window of the house on the dark land. She paused and said, "I'm here to grab ice with them." -I'm incompetent. That's all I can find. When Lz writes a book, don't forget that the psychological activities of the characters can also be combined with the environment ~ or the back is the most commonly used.
