我認(rèn)為沒有什么大的區(qū)別,就是一個(gè)是表語從句,一個(gè)是狀語從句
比如：That is because I love her.
（為什么我...,因?yàn)槲覑鬯?br/>I'm late,because I got up late.
如果非要有區(qū)別,有這樣一點(diǎn)：
狀語從句可以用動詞分詞形式直接表示,表語從句當(dāng)然就不行了,Eg:
He doesn't want to go there because he knows there's a war right now.
改成：Knowing there's a war right now,he doesn't want to go there.
