中文： 在英語系國家中，向陌生人問路時以 'Excuse me' 開頭是基本的禮貌。使用像 'Do you know where...' 這樣的間接問句，比直接問 'Where is...' 聽起來更客氣、更不會有強加於人的感覺。
EN： An indirect question is a question embedded within another question or statement. In this sentence, 'where you want to go' is an indirect question functioning as the direct object of the verb 'tell'. Unlike direct questions, indirect questions use statement word order (subject + verb) instead of question word order (verb + subject). Therefore, we say 'where you want to go' instead of 'where do you want to go'.
中文： 间接问句（Indirect Question）是指嵌入在另一个问句或陈述句中的问句。在本句中，“where you want to go”是一个间接问句，作为动词“tell”的直接宾语。与直接问句不同，间接问句必须使用陈述句语序（主语 + 动词），而非疑问句语序（动词 + 主语）。因此，我们要说“where you want to go”，而不是“where do you want to go”。
Could you tell me what time the train leaves?
你能告诉我火车几点出发吗？
EN： The verb 'tell' is a ditransitive verb, which means it can take two objects: an indirect object (usually a person) and a direct object (usually a thing or a clause). In this structure, 'me' is the indirect object, and the noun clause 'where you want to go' is the direct object.
中文： 动词“tell”是双宾动词（Ditransitive Verb），这意味着它可以接两个宾语：间接宾语（通常是人）和直接宾语（通常是事物或从句）。在此结构中，“me”是间接宾语，而名词从句“where you want to go”则是直接宾语。
She told me the truth.

中文： 在英語系國家中，向陌生人問路時，如果直接問「Where is the bus stop?」（公車站在哪裡？）有時會顯得過於突兀。使用以「I wonder if...」（我想知道是否...）或「Could you tell me...」（你能告訴我嗎...）開頭的間接問句，是英文中非常常見且禮貌的社交策略，能讓語氣聽起來更委婉。
EN： Indirect questions with 'which': When an information question is embedded inside another question (like 'Do you know...?'), it becomes an indirect question. The word order changes from question order to statement order (subject + verb). Here, 'which bus you need' is the noun clause serving as the direct object of 'know'.
中文： 使用 'which' 的间接疑问句：当一个信息疑问句被嵌入另一个疑问句（如 'Do you know...?'）中时，它变成间接疑问句。语序从疑问句语序改为陈述句语序（主语 + 动词）。在这里，'which bus you need' 是名词从句，作为 'know' 的直接宾语。

中文： 在英語系國家中，當你不知道資訊時，說「I am not sure」（我不確定）是一種禮貌且常見的拒絕回答方式，通常比生硬的「I don't know」（我不知道）更受青睞。在句尾加上「now」（現在）暗示價格最近可能有所變動，使語氣更加委婉。
EN： This sentence uses an indirect question (noun clause) as the direct object of the verb 'know'. In English, when a question is embedded within another sentence, it loses its question word order (verb-subject) and takes on statement word order (subject-verb). Here, 'when the next bus comes' is the noun clause, where 'the next bus' is the subject and 'comes' is the verb.
中文： 本句使用了间接问句（名词从句）作为动词“know”的直接宾语。在英语中，当一个问句嵌入另一个句子时，它不再使用疑问句语序（动词+主语），而是使用陈述句语序（主语+动词）。在此处，“when the next bus comes”是名词从句，其中“the next bus”是主语，“comes”是动词。

EN： This sentence uses an indirect question (noun clause) as the direct object of the verb 'tell'.

EN： In informal spoken English, 'than me' is commonly used as a comparative prepositional phrase. In formal grammar, 'than I (do)' is preferred because 'than' acts as a conjunction introducing a clause, but 'than me' is widely accepted and natural in daily conversations.
中文： 在非正式的口语英语中，「than me」常用作比较介词短语。在正式语法中，更倾向于使用「than I (do)」，因为这里的「than」被视为引导从句的连接词。然而，在日常对话中，「than me」已被广泛接受且听起来更自然。
She plays tennis better than me.
她网球打得比我好。
EN： Using 'I think' at the beginning of a sentence is a common way for native English speakers to soften their statements, making them sound more polite, humble, or less demanding when giving directions or advice.
中文： 在句首使用「I think」（我想/我認為）是英語母語者常用的委婉表達方式。在指路或給予建議時，這樣做可以讓語氣顯得更禮貌、謙虛，避免給人強加觀點的感覺。
EN： Indirect questions (noun clauses) introduced by 'if' or 'whether' are used to express uncertainty. Unlike direct questions, indirect questions follow the statement word order (subject + verb) instead of the question word order.
中文： 由 'if' 或 'whether' 引导的间接疑问句（名词从句）用于表达不确定性。与直接疑问句不同，间接疑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 if the library is open on Sundays?
你知道图书馆星期天是否开门吗？
EN： The verb 'know' is a transitive verb that can take a noun clause as its direct object. In this sentence, the entire clause 'if the store is open now' acts as the object of 'know'.
中文： 动词 'know'（知道）是及物动词，后面可以接名词从句作为其直接宾语。在本句中，整个从句 'if the store is open now' 作为 'know' 的宾语。
I don't know if he will come to the party.
我不知道他是否会来参加派对。
EN： In English-speaking countries, asking 'Do you know if...' is a very polite and common way to inquire about store hours, directions, or general information from strangers, as it sounds less demanding than 'Is the store open now?'.
中文： 在英語系國家，使用 'Do you know if...'（你知道是否...）向陌生人詢問店家營業時間、問路或獲取資訊是非常禮貌且常見的表達方式，這比直接問 'Is the store open now?' 聽起來更委婉、不唐突。
EN： The verb 'wonder' is commonly used to express curiosity or a polite inquiry. It is often followed by an indirect question (noun clause) starting with question words 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 she lives.
我想知道她住在哪里。
EN： The phrase 'what time' acts as a conjunction introducing a noun clause. Within this noun clause ('what time it closes today'), the subject is 'it' and the verb is 'closes'. Because 'it' is third-person singular and the statement refers to a regular schedule, the verb 'close' takes the 's' ending ('closes').
中文： 短语“what time”（几点）在此作为连接词，引导名词从句。在这个名词从句（what time it closes today）中，主语是“it”，动词是“closes”。因为“it”是第三人称单数，且此处描述的是常态性的营业时间，所以动词“close”要加上“s”变成“closes”。
EN： In English-speaking cultures, asking 'I wonder...' is considered much softer and more polite than directly asking 'What time does it close?'. It avoids sounding demanding, especially when speaking to service staff or strangers.
中文： 在英語系國家中，使用「I wonder...」（我想知道...）來詢問，比直接問「What time does it close?」（幾點關門？）聽起來要溫和且有禮貌得多。這樣可以避免給人強加要求的感覺，特別是在與服務人員或陌生人對話時。
EN： Indirect questions are used to ask for information in a polite way. When we embed a question inside another question (like 'Can you tell me...'), the word order of the embedded question changes from question order (verb + subject) to statement order (subject + verb). Here, 'how I can join' is used instead of 'how can I join'.
中文： 间接问句用于礼貌地询问信息。当我们将一个问句嵌入另一个问句（如“Can 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）。在此处，使用的是“how I can join”而非“how can I join”。
Could you tell me where the library is?
你能告诉我图书馆在哪里吗？
EN： The modal verb 'can' is used here to express possibility or ability in the future/present, asking about the method or steps required to achieve a goal.
中文： 情态动词“can”在此处用于表示现在或未来的可能性或能力，询问达成某个目标所需的方法或步骤。

EN： In English-speaking countries, joining clubs (such as sports, academic, or hobby clubs) is a very common way to socialize and integrate into a community, especially in school or university settings. Asking 'how I can join' is a polite and standard way to show interest.
中文： 在英語系國家，加入社團（如運動、學術或興趣社團）是社交和融入群體非常常見的方式，特別是在學校或大學環境中。詢問「how I can join」是表達興趣的禮貌且標準的方式。
EN： This sentence uses an indirect question (noun clause) introduced by 'how' as the direct object of the verb 'explain'. Unlike direct questions, indirect questions follow statement word order (subject + verb): 'how you can sign up' instead of 'how can you sign up'.
中文： 本句使用由“how”引导的间接问句（名词从句），作为动词“explain”的直接宾语。与直接问句不同，间接问句必须使用陈述句语序（主语 + 动词），即“how you can sign up”，而非“how can you sign up”。
She will show you how you can use the machine.
她会示范你要如何使用这台机器。
EN： The phrasal verb 'sign up' means to register or join an organization, activity, or service. It is an intransitive phrasal verb in this context, meaning it does not require a direct object.

You need to sign up before the deadline.
你需要在截止日期前报名。
EN： In professional and casual English contexts, offering to 'explain how to do something' is a polite and helpful way to guide someone. Using 'you can' instead of 'you have to' or 'you must' sounds more encouraging and less demanding, which is standard in friendly customer service or peer-to-peer assistance.
中文： 在專業或日常英語語境中，主動提出「解釋如何做某事」是一種禮貌且樂於助人的引導方式。使用「you can」（你可以）而不是「you have to」（你必須）或「you must」（你務必），聽起來更具鼓勵性且較無強迫感，這在友好的客服或同儕互助中是標準的表達方式。
EN： This sentence uses an indirect question (noun clause) as the object of the verb 'know'. In English, when a question is embedded inside another sentence, it loses its question word order (verb-subject) and takes on statement word order (subject-verb). Here, 'who our new teacher is' follows the order: question word (who) + subject (our new teacher) + verb (is).
中文： 本句在动词“know”后面使用了间接问句（名词从句）作为宾语。在英文中，当一个问句嵌入另一个句子时，它会失去原本的问句语序（动词+主语），而改用陈述句语序（主语+动词）。在此处，“who our new teacher is”遵循的顺序为：疑问词 (who) + 主语 (our new teacher) + 动词 (is)。
Do you know where they live?
你知道他们住在哪里吗？
EN： The possessive determiner 'our' is used to show that the 'new teacher' belongs to or is associated with the speaker and the listener(s). It modifies the noun phrase 'new teacher'.

Our team won the game yesterday.
我们队昨天赢了比赛。
EN： An indirect question (noun clause) is used as the complement of the adjective 'sure'. In indirect questions, the word order is subject + verb (what his name is), not verb + subject (what is his name).
中文： 间接问句（名词从句）在此处作为形容词“sure”的补语。在间接问句中，语序必须是“主语 + 动词”（what his name is），而不是疑问句的“动词 + 主语”（what is his name）。
I don't know where she lives.
我不知道她住在哪里。
EN： The structure 'be + not sure + noun clause' is commonly used to politely express uncertainty or lack of knowledge about a specific fact.

EN： Using 'I am not sure...' is a polite and indirect way to admit you do not know something, which sounds softer and more helpful than a blunt 'I don't know'.
中文： 使用「I am not sure...」（我不確定...）是一種禮貌且委婉的承認自己不知道某事的方式，聽起來比生硬的「I don't know」（我不知道）更加溫和且客氣。
EN： Indirect Questions (Noun Clauses): When a question is embedded within another sentence (like 'Could you tell me...'), it becomes an indirect question. The word order changes from question order (verb + subject) to statement order (subject + verb). Here, 'why the bus is late' is used instead of 'why is the bus late'.
中文： 间接问句（名词从句）：当一个问句被嵌入另一个句子中（如 'Could you tell me...'）时，它就变成了间接问句。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）。在此处，使用的是 'why the bus is late'，而不是 'why is the bus late'。

Could you help me with this heavy bag?

EN： In English-speaking cultures, asking 'Why is the bus late?' directly to a driver or station staff can sometimes sound demanding or accusatory. Softening the question with 'Could you tell me...' makes the inquiry polite and more likely to receive a helpful response.
中文： 在英語系國家中，直接詢問「Why is the bus late?（公車為什麼遲到？）」有時聽起來會顯得有些強勢或帶有指責意味。使用「Could you tell me...」來委婉化問題，會使詢問顯得十分有禮貌，也更容易獲得熱心的解答。
EN： The phrase 'have no idea' is a common idiomatic expression meaning 'do not know'. It is often followed by a noun clause starting with a question word (like 'why', 'what', 'where') to express lack of knowledge about a specific matter.
