大全104，关于so that, so as to的用法
104. Among the cossacks, vegetable farming was once so despised that it was forbidden on pain of death.
(A) so despised that it was
(B) so despised to be
(C) so despised it had been
(D) despised enough that it was（A）
(E) despised enough as to be
这题我觉得用B很简洁，A反而复杂了，因为这个forbidden的逻辑主语就是farming,所以不用补出it.请问nn,什么时候要补出it,不是在逻辑主语不是句子主语的情况下吗？在逻辑主语相同的情况下，为什么这里还要补出主语？
