EN： An indirect question (or embedded question) is a question that is placed inside another statement or question. When we embed a question starting with a wh-word (like 'where') inside a main clause (like 'Do you know...?'), the word order of the embedded question changes from question order (verb + subject) to statement order (subject + verb). Therefore, we say 'where the check-in desk is' instead of 'where is the check-in desk'.
中文： 間接問句（或稱嵌入式問句）是指將一個問句放入另一個陳述句或問句中。當我們在主句（例如 "Do you know...?"）中嵌入一個以疑問詞（如 "where"）開頭的問句時，該嵌入問句的語序會從疑問句語序（動詞 + 主詞）轉變為陳述句語序（主詞 + 動詞）。因此，我們要說 "where the check-in desk is"，而不是 "where is the check-in desk"。

你知道博物館幾點關門嗎？
EN： In English-speaking airports, asking staff or fellow travelers for directions using indirect questions like 'Do you know where...?' or 'Could you tell me where...?' is considered much more polite and natural than asking directly 'Where is the check-in desk?'.
中文： 在英語系的機場中，使用間接問句如 "Do you know where...?"（你知道...在哪裡嗎？）或 "Could you tell me where...?"（你能告訴我...在哪裡嗎？）來向工作人員或旅客問路，會比直接問 "Where is the check-in desk?"（報到櫃檯在哪裡？）顯得更加禮貌與自然。
EN： Indirect questions are used to ask for information in a more polite or formal way. They are introduced by a polite phrase (e.g., 'Can you tell me...') followed by a question word (e.g., 'which') and statement word order (subject + verb), rather than question word order.
中文： 間接問句用於以更禮貌或正式的方式詢問資訊。它們由禮貌的片語（例如 'Can you tell me...'）引導，後接疑問詞（例如 'which'）和陳述句語序（主詞 + 動詞），而非疑問句語序。

EN： This sentence uses an indirect question (noun clause) embedded within a polite request.

中文： 本句使用了嵌入在禮貌請求中的「間接問句」（名詞子句）。在英文中，當一個問句被放入另一個句子中時，它會失去原本問句的語序（動詞+主詞），而改用陳述句的語序（主詞+動詞）。在此處，「how I can find my seat」是一個名詞子句，作為主要動詞「tell」的直接受詞。

Do you know what time the movie starts?
你知道電影幾點開始嗎？
EN： This sentence uses an indirect question (noun clause) embedded within a direct question. In English, when a question is placed inside another sentence, it loses its question word order (verb + subject) and takes on statement word order (subject + verb). Instead of 'Where is the restroom?', we say 'where the restroom is'.
中文： 本句使用了嵌入在直接問句中的「間接問句」（名詞子句）。在英文中，當一個疑問句被嵌入另一個句子時，它會失去原本的疑問句語序（動詞 + 主詞），而改用陳述句語序（主詞 + 動詞）。因此，不說 'Where is the restroom?'，而是說 'where the restroom is'。

EN： An embedded question (or indirect question) is a question that is placed inside another statement or question. Here, 'where it is' functions as the noun clause object of the verb 'know'. Unlike direct questions, embedded questions use statement word order (subject + verb) instead of question word order.
中文： 間接問句（或稱嵌入式問句）是指放入另一個陳述句或問句中的問句。在此處，「where it is」作為動詞「know」的賓語（名詞子句）。與直接問句不同，間接問句必須使用陳述句語序（主詞 + 動詞），而非疑問句語序。
Do you know when the train arrives?
你知道火車什麼時候到嗎？
EN： In informal spoken English, 'than me' is commonly used as a comparative pronoun. In formal writing, 'than I (do)' is preferred because 'than' is treated as a conjunction introducing a clause, but in daily conversation, 'than' often functions as a preposition followed by an object pronoun.
中文： 在口語英語中，常用「than me」作為比較級的代名詞。在正式寫作中，通常偏好使用「than I (do)」（將 than 視為引導子句的連接詞），但在日常對話中，than 常被當作介系詞使用，後接賓格代名詞（me）。

會議因為暴雨而延期了。
EN： In English-speaking airports, asking staff or fellow passengers 'Do you know if...' is a very common and polite way to inquire about flight status, as it sounds less demanding than 'Is the flight delayed?'.

EN： The verb 'wonder' is commonly used to express curiosity or polite inquiry. It is often followed by an indirect question (noun clause) starting with a question word like 'what time', 'where', 'how', or 'if/whether'. Unlike direct questions, indirect questions follow statement word order (subject + verb).
中文： 動詞「wonder」（想知道）常用於表達好奇或禮貌的詢問。它後面通常接由疑問詞（如 what time、where、how）或 if/whether 引導的間接問句（名詞子句）。與直接問句不同，間接問句必須使用陳述句語序（主詞 + 動詞）。

中文： 片語「what time」（什麼時間）在此作為連接詞，引導一個名詞子句。在這個子句中，主詞（we）置於助動詞（will）和主要動詞（land）之前。這被稱為嵌入式問句語序（即間接問句語序）。
Do you know what time the train arrives?
你知道火車什麼時候到站嗎？

EN： The sentence uses an indirect question (noun clause) introduced by 'how' as the direct object of the verb 'explain'. In English, indirect questions must follow statement word order (subject + verb) rather than question word order (e.g., 'how you can take' instead of 'how can you take').
中文： 本句使用了由引導詞「how」引導的間接問句（名詞子句），作為動詞「explain」的直接受詞。在英文中，間接問句必須使用陳述句語序（主詞 + 動詞），而非疑問句語序（例如：應使用「how you can take」，而非「how can you take」）。

EN： This sentence uses an indirect question (noun clause) embedded within a direct question.

Here, 'who our tour guide is' is the noun clause acting as the direct object of the verb 'know'.
中文： 本句使用了嵌入在直接問句中的「間接問句」（名詞子句）。在英文中，當一個問句被放入另一個句子中時，它會失去原本問句的倒裝語序（動詞 + 主詞），而改用陳述句的語序（主詞 + 動詞）。在此處，'who our tour guide is' 是一個名詞子句，作為動詞 'know' 的直接受詞。
Do you know where the restroom is?

EN： Indirect Questions (Embedded Questions): When we embed a question inside another question or statement (like 'Could you tell me...'), the word order of the embedded question changes from question order (verb + subject) to statement order (subject + verb).

中文： 間接問句（嵌入式問句）：當我們將一個問句嵌入另一個問句或陳述句中（例如 'Could you tell me...'）時，嵌入問句的語序會從疑問句語序（動詞 + 主詞）轉變為陳述句語序（主詞 + 動詞）。因此，'Why is the line so long?' 會變成 'why the line is so long'。
Do you know where the restroom is?
你知道洗手間在哪裡嗎？
