PREP语法笔记174--补充738
The Emperor Augustus, it appears, commissioned an idealized sculptured portrait, the features of which are so unrealistic as to constitute what one scholar calls an "artificial face".
a.so unrealistic as to constitute
b.so unrealistic they constituted
c.so unrealistic that they have constituted
d.unrealistic enough so that they constitute
e,unrealistic enough so as to constitute
Key: A
OG的解释（从prep中摘录的）：
The verbs are and calls indicate that the sculpture is being viewed and judged in the present. Thus, neither the past tense verb constituted (in B) nor the present perfect verb have constituted (in C) is correct; both suggest that the statue’s features once constituted an artificial face but no longer do so. Also, B would be better if that were inserted after so unrealistic, although the omission of that is not ungrammatical. Choices D and E use unidiomatic constructions with enough: unrealistic enough to constitute would be idiomatic, but the use of enough is imprecise and awkward in this context. Choice A, which uses the clear, concise, and idiomatic construction so unrealistic as to constitute, is best.
请问，照这题的解释，“so...that”结构中that可省略吗？
