小题2:three/3
小题3:skin
小题4:treated
小题5:important

试题分析：烧伤在我们日常生活中是常见的伤害。 热油、蒸气火等等都有可能烧伤人。根据被烧伤的部位所在的皮肤层，有一、二、三三级烧伤。如果治疗不恰当，尤其是第三级，可能会导致很严重的问题。所以急救知识是至关重要的。
小题1:根据burns可知，这里是get burned/burnt 表示被烧伤。get 后加动词的过去分词，表被动。
小题2:根据后面的一二三级烧伤可知，这里是说有三种级别的烧伤。所以填three/3。
小题3:根据被烧伤的部位在哪一个皮肤层来确定烧伤的级别。所以填skin。
小题4:如果治疗不恰当，应该用被动语态，所以用过去分词treated。
小题5:所以急救知识是至关重要的。所以填形容词important，做is的表语。
