语法问题,谢谢!The company, which listed in New York in 2014 in what was then the world's biggest initial public offering of shares, has reported income growth of more than 50% for each quarter for the past two years.
1、请问老师“what was then…”是what引导的名词性从句,what指的是什么,in what 是什么状语,怎么翻译?
2、句子最后的for the past two years 是each quarter 的定语吧?
谢谢老师
