Question

帮忙看看这句话怎么翻译？说一下句子的结构，谢谢

This is because in the early days of radio,those who reported the news were expected to speak excellent English.

Answer 1

我分成了两句解释（原句+翻译+语法解释，一共三行）

This is because in the early days of radio，
这是 因为，早些年在用收音机时，
主+系+表语从句（此处“表语从句”由“原因状语从句”充当）

those who reported the news were expected to speak excellent English.
那些 播报新闻的人 被人们期望讲一口流利的英语
主（由who这个关系代词及其定语从句充当，those是先行词，泛指那些人，由定语从句修饰） 后面是被动语态
