我也有相同的困惑？还有人解答么？？

这个问题真的纠结~~我查了一下论坛里面关于讨论的so as to 的帖子也还真多也。。

应该说so as to ，不管是拆开还是合起来都是可以的，因为都有题目出现过
但貌似有挺多人认可那个is it的倒装不对，说so  ..... as to 里面不用倒装。。。

so x as to y的结构在GMAT语法中是错误的，就好像在GMAT语法中like只能表示像，不能表示喜欢。

so as to不拆开倒是可以对，表示in order to

可不可以这么理解：

啊，我看了但是还是不明白，我就是想知道它为什么不对。。。它不是so... as to...结构的倒装吗？

OG的官方解释：
The construction so x as to y is not a correct  idiom.
