[請益] 關於who在名詞子句裡的用法

[lindaliuys (Lin)]

請問下面這兩個名詞子句

1是對的，2是錯的

1. The teacher knows who our class leader is.
2. The teacher knows who is our class leader.

但是who又可以當主詞，該怎麼解釋2是錯的呢?

推 soquiet:名詞子句不可以倒裝
→ lindaliuys:可以再講解一下嗎?不太懂ㄝ，謝謝
推 monkeywife:Who is our class leader? 這句中的who不是當主詞
→ monkeywife:our class leader才是主詞 所以按照間接問句的句型
→ monkeywife:要改成疑問詞+主詞+動詞
→ monkeywife:who當主詞的例子: Who broke the window?
→ monkeywife:The teacher knows who broke the window.
