1.                  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（B）

(E) Jane Freed’s guileless child narrator takes the operagoer to her opera

答案是B。

但是just as ...so.... 中的so是可以省略的，为什么D不对？是破折号的原因吗？迷惑，请牛牛帮助。
