问题描述:

( )who she was,the assistant was eager to serve her this time.1 not to realize
2 without to realize 3 except realizing 4 with out realizing.请问选择哪个,及分别说出每个为什么对与错
4 多加了一个空格,不好意思,应该是 without realizing

4without realizing.
== as the assistant didn't realize who - -- -,the assistant -- -- .你的句子是由原因状语变过来的,成了分词结构.把从句部分变成分词结构就ok了.
