"reply to" 是英语中常用的动词短语，核心含义为“回复、答复”，需注意 reply 是不及物动词，接宾语时必须搭配介词 to，这与及物动词 answer（可直接接宾语）的用法不同。其音标为 /rɪˈplaɪ tuː/，重音在第二个音节。

用法特点

接回复对象：后接人或事物，表示“对……作出回应”，如回复信件、问题、请求等。

例：She refused to reply to his letters.（她拒绝回复他的信）

不可省略 to：即使口语中也不能说 "reply me"，而需用 "reply to me"。若需省略对象，可直接用 reply（如 "Please reply soon"）。

常见搭配：与 email、question、request、letter 等名词连用，构成 "reply to an email"（回复邮件）、"reply to a question"（回答问题）等表达。

实用例句

请在方便时回复我的邮件。
Please reply to my email at your convenience.

他没有立即回答她的问题。
He did not reply to her question right away.

未能回复广告使她失去了工作机会。
Failure to reply to the advertisement lost her the job.

我将以书面形式答复你的请求。
I will reply to your request in writing.

他们没有回信，似乎暗示缺乏兴趣。
Their failure to reply to our letter seems to imply a lack of interest.

你可以直接回复这条推文。
You can reply to this tweet directly.

请尽快回复此信。
Please reply to this letter as soon as possible.

他站起来答谢欢迎辞。
He rose to his feet to reply to the speech of welcome.

我不确定该如何回答这个问题。
I was unsure how to reply to this question.

兹复你方询盘，我们寄去了最新价目表。
In reply to your inquiry, we have sent you our latest price list.

短语搭配与拓展

介词搭配：in reply to（作为对……的答复），如 "In reply to your letter, we confirm the order."（兹复来函，我方确认订单）

名词形式：reply 可作名词，构成 "a reply to..."（……的回复），如 "I received no reply to my question."（我的问题未获答复）

商务场景：常用于正式沟通，如 "We are expecting your reply to our proposal."（期待贵方对我方提案的回复）

掌握 "reply to" 的用法需注意介词 to 的固定搭配，避免与 answer 混淆。日常使用中，记住 "回复某人/某事" 即 "reply to sb/sth"，就能准确传达沟通意图。
