The adobe dwellings built by the PuebloIndians of the American Southwest are admired by even the most modern ofarchitects and engineers. In addition to their simple beauty, what makes theadobe dwellings admirable is their ability to “air condition” a house without usingelectric equipment. Walls made of adobe take in the heat from the sun on hotdays and give out that heat slowly during cool nights, thus warming the house.When a new day breaks, the walls have given up their heat and are now coldenough to cool the house during the hot day; at the same time, they warm upagain for the night. This cycle goes day after day: The walls warm up duringthe day and cool off during the night and are thus always a timely offset for the outsidetemperatures. As natural architects, the Pueblo Indians figured out exactly howthick the adobe walls needed to be to make the cycle work on most days.
这是2015年高考考试英语全国卷Ⅱ的语法填空题。请问加粗的 natural architects 怎么样理解？有人把 naturalarchitects 翻译成“天生的建筑师”，这是对的吗？若是对的，那样它与 born architects 的不同之处？

natural有不少意义，其中有一个意义等于born。
从上面的例子可以看出，假如表示某种职业，此时的born和natural可以互换，是一个意思。应该注意，born比natural用范围更广。这里的born是形容词，也可以理解成过去分词充当形容词（见章振邦著作）。
但应该注意：
a born loser是惯使用方法，不可换为natural
你提的问题中，born和natural可以互换，意思一样。
