定义 / 说明
间接疑问句是嵌在更长表达中的问题，常用于更礼貌、更柔和、更不直接的提问。常见引导语有 Can you tell me...?、Do you know...?、I wonder...。关键语法点是后半部分不用直接疑问句语序，而用陈述句语序。这个结构在口头请求、服务场景和正式沟通中非常重要。
关键规则
- 先用引导短语：Can you tell me... / Do you know... / I wonder...
- 后半部分用陈述句语序，不是疑问句语序。
- 对比：Where is the station? -> Can you tell me where the station is?
- 嵌入从句里若不需要，不用 do/does/did。
- 用间接疑问句可让对话和邮件更礼貌。
例句
- Can you tell me where the station is? - 你能告诉我车站在哪里吗？
- Do you know what time the shop closes? - 你知道商店几点关门吗？
- I wonder why he left early. - 我想知道他为什么早走。
- Could you explain how this machine works? - 你能解释一下这台机器怎么运作吗？
- Do you remember who called last night? - 你记得昨晚是谁打来的吗？
常见错误
- ❌ Can you tell me where is the station? -> ✅ Can you tell me where the station is?
- ❌ Do you know what does he want? -> ✅ Do you know what he wants?
- ❌ I wonder why did she leave. -> ✅ I wonder why she left.
提示
- 只有前半部分是“提问形式”；后半部分按普通陈述句处理。
