六級詞匯講解:
本句利用主語從句避免了人稱做句子主語，類似的用法還有it is widely/commonly/generally/universally believed/accepted/held/thought/acknowledged that...。by the time在此處意為“在……之前”，如：
By the time our teacher came in，we had started speaking English.
在老師進來之前，我們都已經開始講英語了。

除此之外，by the time還有“這時候，在此時”的意思，相當于at the/that time，如：
By the time he had lost contact with the Party.
這時他已和黨失去聯系。
