 XDF的网络课堂上关于67题这样讲过：so as to总是可以被so that代替

(A) so unrealistic as to constitute

(C) so unrealistic that they have constituted

(D) unrealistic enough so that they constitute

(E) unrealistic enough so as to constitute

 
 
 
 XDF的网络课堂上关于67题这样讲过：so as to总是可以被so that代替

在88题中，如果C选项改为so unrealistic that they constitute，那是不是可以优先选择C，而不选A呢？

这里所讲的so as to总是可以被so that 代替这个观点，是否也可以用在so...as to和so...that结构上呢？

XDF里面还说了 两个都可以用的时候 SO AS TO 要比SO THAT 好，因为88那里SO AS TO 前后的逻辑主语一直，所以要比so that要来得简洁。石林后来还说了 so as to 经常跟 （be）连用 就是 he is so hamdsome as to attract me

不对啊，石林说的是so as to总是可以被so that替换，也就是说，遇到so as to都可以换成so that。他还说：so that对于句子前后的逻辑主语没有要求。so as to前后逻辑主语要一致。

我觉得，用so that就可以避免前后主语、主谓不一致的问题了。

请NNs出来解答一下呀，我和3楼的到底谁说的对啊。

还有，3楼，对于第88题，我是想问的so...as to和so...that是否也是符合这种要求，可以用so...that替换so ... as to?

so as to 要求前后逻辑主语一致， so that不要求前后逻辑主语一致。当两个都可以使用的时候，根据简洁性原则，用so as to

so as to只用于简单的系表结构中，句子主语和to do 的主语相同，且不能倒装。
而so that就把它要广泛地多，从句和主句中的 主语，时态，结构等均可变换，关键的一点：可以用于而且经常用于倒装结构。

而且XDF里面说的是 so that总能代替so as to 没有说so that 优先于 so as to ，88题，so as to 前后逻辑主语一致，所以可以用so as to，再说 so that 选项的时态有问题啊~

我觉得做题时，系表结构 又没有什么逻辑主语不对称问题时，很多时候都选so as to，倒装或前后逻辑主语不对称 选so that~

刚刚找了找CD有关这两个词的区别，有很多结果~ 我看完之后，发现更加混乱~

看一下

不对啊！！我在上海的xdf上说

so as to仅用于简单句子结构，要求逻辑主语必须一致，

so that 可用简单还有复杂，对逻辑主语没有要求！！
