Unlike a hurricane,which can be observed from within,a tornado is so small __________.
A.that such a study has not been practical
E.as to be impractical of study
选A, E为何错,最好能讲讲so...as to和so....that分别在那种情况下更优先被选,THX!!
so that 对于句子前后逻辑主语没要求
so as to要求前后句子逻辑主语必须一致
前面句子逻辑主语是hurricane 后面句子的逻辑主语是 tornado 只能用so that
若说的不对请高手指教
