※ 引述《DreamerSun (都利姆桑)》之銘言：
: 前輩好！
: 小弟最近對於以下文法卡好久，一直想不通，
: A) I will show him who is the boss.
: B) I don't know who he is.
: 請問這兩句 who 後面的動詞位置不一樣的原因是？
: 為何 A) 不是 who the boss is?
: 謝謝大家！

因為懶得在BBS裡上色XD
以下是文字版
----
A) I will show him who is the boss.
B) I don't know who he is.
1.這兩句的都是名詞子句。
2. I will show him who is the boss.這句後面的who is the boss並沒有倒裝，因為
who本來就是主詞，誠如s831111所說的：
問：Who（主詞）is the boss?
答：Tom（主詞）is the boss.

參考
Practical English Usage 3rd. 278.7
Questions beginning "who/what/which + be" can ask for a subject or a
complement. Compare:
以who ;what ; which+ be 開頭的疑問句可就主語或補語進行提問。試比較：
Who is the best player here? 誰是這兒最好的選手？
(This asks for a subject: a possible answer is John is the best player here.)
（這是就主語進行提問：可能的回答是John is the best player here）
What is the time?
(This asks for a complement: a possible answer is The time is 4.30, NOT 4.30
is the time.)
（這是就補語進行提問：可能的回答是The time is 4.30，不能說：4.30 is the time.)
When we report the first kind of question (where "who/what/which + be" asks for
a subject), two word orders are possible.
在轉述第一種疑問句（這裏的who / what / which + be 就主語進行提問）時，有兩種可
用的詞序。
DIRECT:
Who's the best player here?
INDIRECT:
She asked me who was the best player.
She asked me who the best player was.
DIRECT:
What's the matter?
INDIRECT:
I asked what was the matter.
I asked what the matter was.
DIRECT:
Which is my seat?
INDIRECT:
She wondered which was her seat.
She wondered which her seat was.
This does not happen when "who/what/which" asks for a complement.
當who/what/which 就補語進行提問時，則只能有一種語序：
DIRECT:
What's the time?
INDIRECT:
She asked what the time was. (NOT USUALLY She asked what was the time.)
（通常不能說：She asked what was the time.)

回到本題：
※I will show him who is the boss.
這句的問句是who is the boss? 明顯問的是「問句中的主詞/主語who」，回答可能是
Tom (is the boss.)（因為這個問句中的主詞在回答時也是主詞，因此寫成間接問句時，
語序就不需要變動，本來就是「主詞+動詞」的順序。）
不過若照Practical English Usage的說法，問「主詞/主語」時，可以有兩種間接問句寫
法：
I will show him who is the boss.
I will show him who the boss is.
※I don't know who he is.
這句的問句是Who is he? 問的是「問句中的主詞補語he」，回答可能是He is the
boss. （因為這個問句中的主詞補語he，在回答時變成主詞了，因此寫成間接問句時，語
序需要變動，要把he放到is前面，寫成I don't know who he is.這樣才是「主詞+動詞」
的順序，而who在這裡就是名詞子句連接詞）
照Practical English Usage的說法，問主詞補語時只能有一種寫法：I don't know who
he is.
