查询词典 ripple current

How blessed is the little toddling thing who can lie flat in the sunshine and drink in the beauty of the "green things growing," who can live among the other little animals, his brothers and sisters in feathers and fur; who can put his hand in that of dear mother Nature, and learn his first baby lessons without any meddlesome middleman; who is cradled in sweet sounds "from early morn to dewy eve," lulled to his morning nap by hum of crickets and bees, and to his night's slumber by the sighing of the wind, the plash of waves, or the ripple of a river.

这个蹒跚学步的小家伙能尽情地躺在阳光下，欣赏着绿色植物生长；他被大自然中的兄弟姐妹，即身着羽毛或皮毛的小动物们陪伴；他把小手交给到了自然母亲的手中，不受打扰地学到了人生的第一堂课；从清晨到傍晚，他被美妙的歌声所环绕，在蟋蟀和蜜蜂的呤唱中小睡片刻，。。。。
