This is because in the earlydays of radio, those who reported the news

were expected to speak excellent English.分析此句子的句子结构,成分。
中间打错。改:early days

主句主语是this,系动词是is,表语是because引导的表语从句,in the early days是时间状语,of radio作定语修饰前面名词days.
because引导表语从句,主语是those,系动词是were,to speak excellent English是表语。
定语从句修饰前面代词those。主语是who,谓语是reported,宾语是the news.

这是从属连词because引导的表语从句。

those who reported the news were expected to speak excellent English定语从句。先行词those在从句中当主语。

in the earlydays of radio。时间状语
