ask: implies no more than the putting of a question: ~ for directions.     （question本组第二个，在这里解释第一个，说明是基础词，来自词根QUIS表示寻找=to seek,obtain，即提问问题是寻找信息。后续很多词都用到quis或quir如inquire,require）

question: usually suggests the asking of a series of questions: ~ed them about every detail of the trip.

interrogate: suggest formal or official systematic questioning: the prosecutor ~d the witness all day.          （ROG词根表示提议法律to propose a law，如abrogate表示废除法律，本例中字面意思是互相提议法律，实际意思是讯问审问） 系统system强调发展完备well developed
