OG12 语法第六题 so...as to

because of moisture that was exhaled by
tourists raising the humidity within them to levels
so high as to make the salt from the stone
crystallize

这句话是错的，但是我想讨论一点，就是to levels so high as to do 这种说法是正确的吗？OG里没有解释这一点

因为我们通常都说to so high levels as to do

求教了。谢谢。。

to levels so high as to do 是可以的。但你的举例中用so错了，应该是to such high levels as to do

so as to 只是用在单一主谓中的哦
