not even的使用方法

And there I was, also preparing to get off at the Atlantic Avenue, with nothing to take care of —not even the usual customary book under my arm.

破折号后面的是补充说明的意思吗？是否可以这么理解：he did not take care of even the usual customary book under my arm.



破折号后为插入语，是对nothing的补充说明。

And there I was, also preparing to get off at the Atlantic Avenue, with nothing to take care of —not even the usual customary book under my arm.

我就站在那里，也筹备在Atlantic大街下车，什么心都不需要操——甚至也不操心一般习惯性的夹在我腋下的书。
