The children have been "riding" all morning, and are tired; their parents, who have been "walking" all morning alongside the centipede, passing up water and holding umbrellas to shade their children from the sun, are tired too; they all unroll straw mats or unfold deckchairs to take a quick nap.
孩子們「坐」了一個上午，累了；跟在一旁遞水、撐傘的父母，「走」了一個上午也累了，紛紛鋪起草席或張開躺椅小睡片刻。
