剖析: He knows and I know that he knows.

He knows and I know that he knows

请问专家，这个句子的意思是，应该怎么样翻译？谢谢！

He knows and I know that he knows.

在没上下文的状况下，这个句子有两种可能的理解：

1. 把 that he knows 看作是 I know 的宾语从句：

He knows and I know that he knows. 他了解，我了解他了解。

若是如此的话，可以考虑在 and 前加一个逗号：

He knows, and I know that he knows.

2. 把 that he knows 看作是 He knows 和 I know 一同的宾语从句：

He knows and I know that he knows. 他了解他是了解的，我也了解他是了解的。

若是如此的话，可以考虑在 and 和 that 前前各加一个逗号：

He knows, and I know, that he knows.

注：若是口语中说话，则在逗号处有停顿。
