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： 间接问句（或称嵌入式问句）是指将一个问句放入另一个陈述句或问句中。当我们在主句（例如 "Do you know...?"）中嵌入一个以疑问词（如 "where"）开头的问句时，该嵌入问句的语序会从疑问句语序（动词 + 主语）转变为陈述句语序（主语 + 动词）。因此，我们要说 "where the check-in desk is"，而不是 "where is the check-in desk"。

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： 间接问句用于以更礼貌或正式的方式询问信息。它们由礼貌的短语（例如 'Can you tell me...'）引导，后接疑问词（例如 'which'）和陈述句语序（主语 + 动词），而非疑问句语序。

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

中文： 本句使用了嵌入在礼貌请求中的“间接问句”（名词从句）。在英文中，当一个问句被放入另一个句子中时，它会失去原本问句的语序（动词+主语），而改用陈述句的语序（主语+动词）。在此处，“how I can find my seat”是一个名词从句，作为主要动词“tell”的直接宾语。

Do you know what time the movie starts?
你知道电影几点开始吗？
EN： This sentence uses an indirect question (noun clause) embedded within a direct question.

Instead of 'Where is the restroom?', we say 'where the restroom is'.
中文： 本句使用了嵌入在直接问句中的“间接问句”（名词从句）。在英文中，当一个疑问句被嵌入另一个句子时，它会失去原本的疑问句语序（动词 + 主语），而改用陈述句语序（主语 + 动词）。因此，不说 'Where is the restroom?'，而是说 '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： 间接问句（或称嵌入式问句）是指放入另一个陈述句或问句中的问句。在这里，「where it is」作为动词「know」的宾语（名词性从句）。与直接问句不同，间接问句必须使用陈述句语序（主语 + 动词），而不是疑问句语序。
Do you know when the train arrives?
你知道火车什么时候到吗？
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： 在口语英语中，常用「than me」作为比较级的代词。在正式写作中，通常更倾向于使用「than I (do)」（将 than 视为引导从句的连词），但在日常对话中，than 常被当作介词使用，后面接宾格代词（me）。
She is much taller than me.
她比我高得多。
EN： Using 'better than me' is a polite and humble way to defer to someone else's knowledge, especially when navigating or asking for directions. It acknowledges the other person's expertise or familiarity with the environment, fostering a friendly and cooperative atmosphere.

EN： This sentence uses an indirect question (noun clause) introduced by 'if' (meaning 'whether'). In indirect questions, the word order is subject + verb (the flight is delayed), not verb + subject (is the flight delayed).
中文： 本句使用了由“if”（意为“是否”）引导的间接问句（名词从句）。在间接问句中，语序应为“主语 + 动词”（the flight is delayed），而非疑问句的“动词 + 主语”（is the flight delayed）。

你知道博物馆今天是否开放吗？
EN： The passive voice 'is delayed' is used here. The passive voice is formed with 'be' verb + past participle (V-ed) to show that the subject (the flight) receives the action.
中文： 此处使用了被动语态“is delayed”（被延误/延期）。被动语态的结构为“be 动词 + 过去分词 (V-ed)”，用以表示主语（航班）承受该动作。
The meeting was delayed because of the heavy rain.
会议因为暴雨而延期了。
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?'.
中文： 在英語系國家的機場，向工作人員或其他旅客詢問時，使用「Do you know if...」（你知道是否...）是非常常見且禮貌的問法，聽起來比直接問「Is the flight delayed?」（班機延誤了嗎？）更為客氣委婉。
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： 动词“wonder”（想知道）常用于表达好奇或礼貌的询问。它后面通常接由疑问词（如 what time、where、how）或 if/whether 引导的间接问句（名词从句）。与直接问句不同，间接问句必须使用陈述句语序（主语 + 动词）。
I wonder where they are going.
我想知道他们要去哪里。

中文： 短语「what time」（什么时间）在此作为连词，引导一个名词性从句。在这个从句中，主语（we）置于助动词（will）和主要动词（land）之前。这被称为嵌入式问句语序（即间接问句语序）。
Do you know what time the train arrives?
你知道火车什么时候到站吗？
EN： Using 'I wonder...' is a very polite and indirect way to ask for information in English, especially in service scenarios like airports or hotels. It sounds less demanding than directly asking 'What time will we land?'.
中文： 在英文中，使用「I wonder...」（我想知道...）是一種非常禮貌且委婉的詢問方式，特別常用於機場或飯店等服務場景。這聽起來比直接問「What time will we land?」（我們什麼時候降落？）更具親和力且不顯突兀。

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： 本句使用了由引导词“how”引导的间接问句（名词从句），作为动词“explain”的直接宾语。在英文中，间接问句必须使用陈述句语序（主语 + 动词），而非疑问句语序（例如：应使用“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问句中的“间接问句”（名词从句）。在英文中，当一个问句被放入另一个句子中时，它会失去原本问句的倒装语序（动词 + 主语），而改用陈述句的语序（主语 + 动词）。在此处，'who our tour guide is' 是一个名词从句，作为动词 'know' 的直接宾语。
Do you know where the restroom is?

EN： An indirect question (or noun clause) is used inside another sentence.

EN： In English-speaking cultures, admitting you don't know or remember someone's name using 'I am not sure what his name is' or 'I'm sorry, I've forgotten his name' is considered polite and normal, especially in busy social or professional settings. It is preferred over guessing incorrectly.

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). Therefore, 'Why is the line so long?' becomes 'why the line is so long'.
中文： 间接问句（嵌入式问句）：当我们把一个问句嵌入另一个问句或陈述句中（例如 'Could you tell me...'）时，嵌入问句的语序会从疑问句语序（动词 + 主语）转变为陈述句语序（主语 + 动词）。因此，'Why is the line so long?' 会变成 'why the line is so long'。
Do you know where the restroom is?

EN： In English-speaking cultures, especially in service environments like airports, hotels, or restaurants, starting a question with 'Could you tell me...' or 'Excuse me, do you know...' is considered much more polite than directly asking 'Why is the line so long?'.
