鱼儿在水中，鸟儿在天上，花儿在枝头。掉在地上的花朵叫枯萎，落在沙漠上的鱼儿叫死亡，那在地上蠕动的不是动物就是昆虫。 春天，小燕子向北飞，才能飞到北方。秋天，小燕子向南飞，才能飞到南方。那是多么漫长的路啊。还有沙漠上叮叮当当作响的驼铃。不经艰苦，它们如何能到达目的地? Fish in the water, birds in the sky, flowers in the branches. The flowers that fall to the ground are wilted, the fish that fall on the desert is called death, and that is not an animal or an insect that creeps on the ground. In spring, a small swallow fly north to fly to the north. In autumn, a small swallow fly south to fly to the south. What a long way that ah. There are camels ringing in the desert. How can they reach their destination without any hardship?
