虛擬語氣 would have done 有幾個含義呢？

If I had realised that she would repeat the story that I had told her confidentially, I should have changed the names of the people who

were involved so that even though the facts become public no one would have known.

章振邦高級英語語法482頁。

假如當時我料到她會把我私下告訴她的事情和盤托出，我當時就會把有關人等的名字改掉，即便后來事情揭秘，也不會有人了解他們的真實身份。

我的困惑：even though the facts become public no one would have known. -

是不是應該改成even though the facts become public no one would know. ? - 這是對以后的虛擬吧！

為何原文用了no one would have known. 呢？這是對過去的虛擬嗎？ 還是這里的would have known也可以其實是will have done 以后完成時的虛擬呢？

我非常困惑，麻煩老師解析這里的would have known...謝謝！



我批評過你多次了，讀英文不注意句子表達的邏輯，不注意全句，只看局部。

這個句子的開頭就用虛擬if從句對你說一個與過去事實相反的假設: 如果當時我意識到她會把事情和盤托出...，這了解對你說實質我沒意識到這一點，事實上她已經把事情和盤托出了，有關職員的名字也讓人了解了。假如你讀這句話理解不到這一點，你就應該好好檢討我們的閱讀能力了。正由于目前大伙了解了有關人的真實名字，我才懊悔當初沒把人名改一下。所以，最后的no one would have known 沒人會了解人名是與過去事實相反的，而不是與以后事實相反。
