She became completely absorbed __13__ her work，so that after only a month at work she could no longer understand how she had ever managed without having a job.
题目解答
答案
一、题目含义：
她变得完全投入于她的工作，所以在工作后只有一个月，她再也不能理解她曾经没有工作时如何管理。
二、无提示词，考虑冠词/代词/介词/连词，由be absorbed in表示“投入于...”的结构可知本题答案为介词in
解析
步骤 1：识别句子结构
句子的前半部分是"She became completely absorbed __13__ her work"，后半部分是"so that after only a month at work she could no longer understand how she had ever managed without having a job."。前半部分是一个主谓宾结构，后半部分是一个结果状语从句。
步骤 2：分析空白处的语法功能
空白处需要填入一个介词，因为"become absorbed"是一个固定搭配，表示"全神贯注于"，后面需要跟一个介词来引导宾语。
步骤 3：确定正确介词
根据固定搭配"become absorbed in"，空白处应填入介词"in"，表示"全神贯注于她的工作"。
