答案解析
正确答案：D
解析：
这是一道词义辨析的题目，需要准确理解语境、并把握每个选项词语的准确含义和用法。首先，梳理题目中的关键信息：
（1）句子描述的是主人公在忙碌的早晨进行的一系列活动，最后到达办公室后的情况。
（2）空格需要填入一个修饰“deep breaths”的短语，表示主人公到达办公室后进行了几次深呼吸。
接下来，分析各选项：
A. a great deal of：意为“大量的”，通常用于修饰不可数名词，但“deep breaths”是可数名词的复数形式（尽管在实际语境中我们并不严格区分其可数或不可数），因此A项不合适。
B. a number of：意为“许多”，用于修饰可数名词的复数形式，但“deep breaths”虽然形式上是复数，但在这种语境下更强调的是“几次”深呼吸，而非“许多”深呼吸，因此B项也不贴切。
C. a lot of：意为“许多”，同样既可以修饰可数名词也可以修饰不可数名词，但同样存在B项的问题，即不强调“几次”的概念。
D. a couple of：意为“几个，几个（人或物）”，在这里可以理解为“几次”，用于修饰“deep breaths”非常合适，表示主人公进行了几次深呼吸来放松。
因此，根据语境和各选项的含义，最合适的答案是D：“
