题目

In So far as any inquiry is a secret one,it naturally limits all those engaged in carrying it out from effective contact with their fellow scientists either in other countries or in universities ,or even,often enough,in other departments of the same firm.这句话里面a secret 的后面为什么要加one?还有,or even,often enough是啥意思?一个短语吗?

答案

secret在这里是做形容词,所以后面跟了一个代指的名词one
还有你说的or even,这个不是短语,这里的even是'还有'（后面说到了department）,两个or都和either有关
而often enough只是作插入语,说前面这个情况后面也经常在公寓里出现
