not only...but also連接從句時的用法？

請問假如not only...bualso結構連接兩個從句，是不是直接將從句視為名詞短語或形容詞短語，而無需對從句進行倒裝呢？如：

Not only what he did but also what he said are correct.

直接將兩個what引導的名詞性從句視為名詞短語，而不需要倒裝兩個從句。



另外，假如not only...bualso是內嵌到從句中，則需要倒裝從句內的結構，如：

The newemployee soon proved that not only was he capable but he could also be trusted.

即that引導的包括not only...bualso結構的從句？

Not only what he did but also what he said iscorrect.

名詞性從句，在句中其用途等于一個名詞。被 not only...but also...連接后，本身沒辦法形成倒裝， not only A but also B （A、B代表兩個名詞）。

The new employee soon proved that not only was he capable but he could also be trusted.

that 后的賓語從句，對于包括的not only...but also... 而言，是一個獨立的句子。所以，根據倒裝規則進行倒裝即可。
