a part of some swimming pools or water parks in which a slow-flowing current of water carries people or small boats along

We spent our mornings at the heated indoor swimming pool with its lazy river, wave machine, and flumes. 我们每天早上都在室内温水游泳池里度过，享用那里的懒人河、造浪机和水槽。

Just float along in the slow-moving lazy river or drift in the large wave pool. 轻松地漂浮在缓缓流淌的懒人河中，或在大浪池中随波漂流。
