One reason why it is hard to design and teach such courses is that they can cut across the insistence by TOP American universities that liberal-arts educations and professional education should be kept separate, taught in different schools.
这里为什用by短语作后置定语，我感觉应该用of？？？这by和of当定语用有什么不同
insistence与TOPAmerican universities之间是逻辑主谓关系，用介词of和介词by都是可以的。比如，Tom’s arrest by police shocked everybody. 因为介词of既能够表示主谓关系，也可以表示动宾关系，当强调主谓关系或者为了防止误读为动宾关系时，就用by引出逻辑主语。
