no disciplines have seized on professionalism as much enthusiasm as the humanities /no disciplines have seized on professionalism with the humanities 明白了？

with enthusiasm 作状语，
as much enthusiasm as... 仍需要加with才能构成句子状语:
The humanities have seized on professionalism with much enthusiasm.
The humanities have seized on professionalism with as much enthusiasm as possible.
不能说...have seized on professionalism much enthusiasm. 缺少介词
句子完全展开是这样的：
No disciplines have seized on professionalism with as much enthusiasm as the humanities have seized on professionalism.
