解析
我们可以根据上下文逻辑逐一匹配选项：
16空：前文提到洪水席卷区域、数十万人受影响，后文给出具体的伤亡失踪数据，C选项“这场灾难给人们的生命造成了巨大损失”可以承上启下，符合语境。
17空：前文说明洪水往往毫无预警就发生，后文介绍洪水可以冲倒树木、摧毁建筑的破坏力，F选项“山洪流速很快，还有强劲的水流”可以引出后文对洪水破坏力的描述，逻辑通顺。
18空：前文提到洪水过后水和食物这类基础物资无法送达灾区，E选项“缺少干净的水和食物可能会引发新的问题”承接上文，对应前文的物资短缺情况。
19空：前后文都在介绍被困在被洪水淹没的建筑里的自救方法：先去最高层，必要时再到屋顶求救，D选项“如果被困在被洪水淹没的建筑里，不要害怕”符合此处的自救场景语境。
20空：前文引出洪水过后的注意事项，后文提到只能用瓶装水或者煮沸的水饮用、做饭、洗澡，B选项“不要喝洪水，也不要用它来清洗食物”和后文的用水安全提示内容衔接紧密。
