用Wh疑問辭開頭的問句，我們叫它們＂直接問句＂。比如說：What are you doing?When will you arrive in Taiwan?Who is singing in the classroom?Where is my wallet?Why is he absent?How do you go to school?但是如果這些句子變成子句，就會變成所謂的＂間接問句＂，間接用句的語法很簡單，其排列的順序，就是疑問詞＋主詞＋動詞。所以第一句：I don't know what I should do. 這句話是對的。Please let me know when I should leave. 這樣子才對。第二句也一樣：Can you tell me why you are learning English? 這樣子的順序才對，就時態言，在問對方現在學英文的原因。Can you tell me how you learned English? 這句話的句型跟上面一句差不多，但是如果你問為什麼learn要用過去式，那就是表示過去發生的一件事情，故用過去式；如果用現在式learn的話，語意就有點怪，因為learn這個字有＂學成＂的意思，既然已經學成，當然就要用過去式比較符合邏輯；如果硬要用現在式，用"study"這個字會是最好的。How to do it的"it"是不可以省略的，但是What to do後面就不可以有it，原因是How無法直接拿來當作do的受詞，但What是可以的。what to do    ^_____|how to do it             |__^問句中的Can以Could, Would, Should等過去式助動詞來取代，表示的是更為禮貌的語氣。Could you help me? 這一句話，就比Can you help me? 這句話更為禮貌。另外一種情況，就是遇到了過去式。Can he speak Chinese now? <- 問現在他說中文的能力。Could he speak Chinese when he lived in Taiwan? <- 問過去他住在台灣時，口述中文的能力。

檢查倒裝句又一個訣竅, 就是把 5W1H (Who, Where, What, When, and How) 之前, 包括 5W1H 遮起來, 後面是一個完整句子, 就對了.
例如: I don't know what I should do. => (I don't know what) I should do.
I should do. 是一個完整句子對了.
又例如: Can you tell me why are you learning English? => (Can you tell me why) are you learning English? 就錯, 因為 are you learning English 是一個問句, 不是句子.

1. I don't know (what I should do.)
　Please let me know (when should I leave.) 比較2句
　請問什麼時候名詞子句要倒裝?請解釋用法,謝謝!
-- 這個的第二句應該也要倒裝:
Please let me know when I should leave.
只要是5W1H問句是附加在一個句子(S+V)或問句之後, 這5W1H問句的S和V要倒裝.

問句中開頭can有時又用Could or would,何時用?

-- Can you tell me why you are learning English? 才對, 這句要倒裝>
Can you tell me how you learned English. 是 Can you tell me? 和 How did you learn English? 合在一起. 當兩句合起來, 後一句要還原變句子. 所以 did 要跟 learn 合在一起變一個字.

至於你說 how to it, 我就不是很確定你的意思了.

Can 開頭的問句很直接, 是問能力的事, 若請人幫忙時用Can比較沒禮貌.

出現Could或Would的時候, 是用在假設語氣.
例如: If you didn't mind, would you open the window for me?
省掉If you didn't mind, 就是我們平常聽到的 Would you open the window for me? 的 Would 問法.

Could 是 Can 假設語氣時用的; Would 是 Will 假設語氣時用的.
