〜とのことだ

N3

普通形 + とのことだ

「〜とのことだ」类似于「听说」或者「据说」的意思。
它用来引述别人的话或消息，表达某种信息是从别人那里听来的，而非自己亲身经历或了解的。
比如，你听说某人要结婚了，就可以说:听说他要结婚了。
再比如，你得知某地发生了地震，可以说:据说那个地方发生了地震。
这个语法用来传递第三方的信息或传闻，强调信息来源不是自己。

"~とのことだ" is used to convey information that the speaker has heard from a source or learned from a certain place.
It is often used to report what someone else has said or to relay information that the speaker has obtained indirectly.
This structure is similar to saying "I heard that" or "It is said that" in English.
For example, if you say "彼は明日来るとのことだ" (Kare wa ashita kuru to no koto da), it means "I heard that he will come tomorrow" or "It is said that he will come tomorrow", indicating that the information is based on what you have heard from someone else.
