[讨论]Just as..., so 中的SO是否必须？

大全466

466. Just as reading Samuel Pepys’s diary gives a student a sense of the seventeenth century—of its texture and psyche—so Jane Freed’s guileless child narrator takes the operagoer inside turn-of-the-century Vienna.
(A) so Jane Freed’s guileless child narrator takes the operagoer
(B) so listening to Jane Freed’s guileless child narrator takes the operagoer
(C) so the guileless child narrator of Jane Freed takes the operagoer
(D) listening to Jane Freed’s guileless child narrator takes the operagoer
(E) Jane Freed’s guileless child narrator takes the operagoer to her opera

B 跟D的区别只有一个SO， 请问一下这个SO 是必须的吗？

但我在大全里搜到好多JUST AS 。。。后边不带SO的句型，请NN解释一下，谢谢

我想标准情况，是so不省,也就是just as...so...优于just as...

这就像not only...but also...这里also平时也可省,但在gmat中就被认为不好或是错。

另外,Just as...so...的用法你可参考一下刘振民的那本书，里面有个小结，蛮好的。
