...had nowhere to turn except to the nearest cabin.解释except,在此只能是连词引导状语从句...
except在此只能是连词引导状语从句,完整为except he turned to…,省略了he turn ,

Answer 1

except可以做连词引导一个从句,但是except不能单独引导从句,必须是except that,例如：It is a good hotel except that it is noisy.有的时候也有except when,例如：He usually goes to work by bicycle except when it rains.但是except不可单独引导从句.
except还可以作介词,后面接名词、代词、不定式、副词、介词短语.
因此在这里,except作介词,后面接介词短语to the nearest cabin.
不需要把except理解为引导一句省略"he turn" 的从句,因为它本身的用法中就可以在后面接介词短语的.而且,省略了主语谓语的从句根本就构不成句子,就不是从句.
如果要把后面的介词短语改成从句的话,应该是except that he turn to the nearest cabin.
