This was but a bad omen of the reception which he was to expect;but a worse followed,when,upon inquiry for his daughter and her husband,he was told they were weary with traveling all night,and could not see him;and when lastly,upon his insisting in a positive and angry manner to see them,they came to greet him,whom should he see in their company,but the hated Goneril,who had come to tell her own story and set her sister against the king her father!此處的whom是引導(dǎo)定語從句嗎，若是的話 先行詞應(yīng)該是the hated Goneril，為何放在后面了？

and when lastly,upon his insisting in a positive and angry manner to see them,they came to greet him,whom should he see in their company,but the hated Goneril,who had come to tell her own story and set her sister against the king her father!

我簡化一下這個句子：

When they came to meet him, whom should he see in their company but Coneril !.

當(dāng)他們來見他的時候，他看到和他們在一塊的除去Goneril還能有哪個！

這個主句是個由修辭性問句演變而來的廣義的感嘆句。即和他們一塊兒的居然是Coneril！

but在此為介詞，意為除去。

特殊疑問句也可以用作修辭性問句。一定的修辭性表示強(qiáng)烈的否定意義，否定的修辭性問句表示強(qiáng)烈的一定意義。本句在形式上是一定句，所以表示的是強(qiáng)烈的否定意義。即除去Coneril, 和他們一塊兒的沒其他人。

修辭性問句句末讀驟降調(diào)，就成了廣義的感嘆句。比如：

Who doesnt know Ma Yun? 哪個不了解馬云？

= Everyone knows Ma Yun. 所有人都認(rèn)識馬云。

Who doesnt know Ma Yun! 哪個不了解馬云！

= Everyone knows Ma Yun! 所有人都了解馬云！
