- And it's coming.
要下雨了 - When the summer monsoon blows in
当夏季季风吹来时 - the giant saguaros, one of the biggest of all cacti,
巨大的弁庆柱 ——一种世界上最大的仙人掌 - are ready to take full advantage of it.
准备充分利用雨水 - After a rainstorm the saguaro's long shallow root system sucks up the water
暴风雨过后 弁庆柱 用又长又浅的根系吸收水分 - and the pleats on its trunk enable it to expand rapidly.
茎上的皱褶使之能迅速膨胀 - When full, a saguaro stem can store up to five tonnes of water
吸饱水后 弁庆柱的茎干中 已储存了5吨左右的水
