我不太明白，为什么不能说 a tornado be impractical of study? a tornado 不能 be impractical of study 吗？ 我觉得可以啊
the subject is so general as to be impractical of study 这句话对不对呢？ 请给详细分析一下 谢谢！
我个人觉得，你说的对，"so small as to be impractical of study"是合适的，基于以下Ron的解说，跟这个例子类似： I am so ugly as to be viscerally repulsive towomen. 但鉴于braveMBA前辈持相反态度，我不敢100%确定....就不误导你了，直接贴Ron大神的解说。 呼唤讨论~~~~
以下是摘录： “so as to” is an interesting construction. i don't think thatgmac likes it very much -- i've never seen it in an officially correct answer-- but i think the main distinction is that it's used to describe indirectintentions. for instance, the example above isn't great because you are calling this persondirectly to invite him, so you should use one of the earlier twoversions.
on the other hand, consider the following: Joebought a gym membership so as to become more attractive to women. this is what i mean by indirect intention. obviously, the act of buyinga gym membership itself is not going to make joe instantly more attractive towomen (women do not swoon over a man's gym membership card). instead, there areplenty of implied intermediate steps between “by a gym membership” and “be moreattractive”; the use of “so as to” implies that there are such intermediatesteps in the process.
once again, this is a very writerly difference. i think it's fun to try toexplicate it -- i've definitely never thought about these things consciouslybefore -- but i can guarantee that you will not be tested on this kind ofdifference. ----------------- ingeneral, you don't use so ADJ as to VERB unless the VERB describes somesort of state/condition. i.e., if the verb is an action verb, thisconstruction generally isn't used. for instance, i am so ugly as to be viscerally repulsive to women. --> this works, because the verb “to be” describes astate/condition. i am so ugly as to repel women on sight. --> you generallywouldn't see this in good writing, as “repel” is an action verb; the sentencewould probably be written as i am so ugly that i repel women on sight
------------------------------- In OG, it is because ambiguityin meaning. Congress is debating a bill requiring certain employers to provide workers withunpaid leave so as to care for sick or newborn children. => INCORRECT Congress is debating a bill requiring certain employers to provide workers withunpaid leave so that they can care for sick or newborn children. => CORRECT -by student thisis a whole different issue. in the construction “so as to”, there is no changeof subject, and so there's an implication that the subject is the same as thesubject of the previous clause/action.
that's a big issue here, because the only subjects of actions in the previousclauses are "congress" and "certain employers". therefore,the sentence is implying that one of these two entities is actually going tocare for sick or newborn children! not good. the sentence needs to be written in a way that changes the subject..

Althoughresearchers have had new transducer designs in mind for years,ithasbeenimpracticaltoconstructthemsubtractively.
— adj
1.
not practical or workable: an impractical solution
2.
notgiven to practicalmattersorgifted with practical skills: heisintelligent but tooimpractical for commercialwork
这里，我觉得应该是第一个意思，应该把of改成to "be impractical to study"
另外一点，这题正确答案是A选项： Unlike a hurricane, which can be observed from within, a tornado is so small that such a study has not been practical.
注意到划线部分时态，现在完成时，表达了“迄今为止”尚未实现的意思。 E选项"so small as to be impractical of study"，就丢掉了现在完成时能够表现的“迄今为止”的含义！
SC里，当且仅当A选项意思illogical or ambiguous的时候，才允许修改句意。
