各位老師好，句子如下：

Little did he know, Apple would eventually balloon to become the world’s most valuable company, the first to reach a covet.

我想了解Little did he know的成分。里是個插入語么？還是接在后面“Little did he know that Apple…………”

謝謝老師。

Little did he know, Apple would eventually balloon to become the world’s most valuable company, the first to reach a covet.

網友的理解是正確的，Little did he know是插入語分句，其后為主句。

假如改為Little did he know that...則little did he know為主句，that引導賓語從句。二個句子有什么區別是，主句表示主要信心，從句表示次要信息。

假如說話人想突出Apple would...分句的內容，就將Little did he know用作插入語，Apple would分句為主句。

假如說話人想突出He knew little，則用其做主句，Apple分句作賓語從句。

二個句子的意思相同，只不過信息的側重點不同。
