"that"本身 不能引导原因状语从句，但在某些特定情况下，"in that"可以引导原因状语从句，相当于"because"。例如：

1. This book is different from that book in that this one is about chemistry and that one about history.

2. The weather is cold, that's why we need to wear warm clothes.

3. I rejoice that you are coming home.

在这些例子中，"in that"和"that's why"都起到了解释原因的作用，使句子之间的逻辑关系更加清晰。
