"Believe me, my dear sir, my gratitude is warmly excited by such affectionate attention; and depend upon it, you will speedily receive from me a letter of thanks for this, as well as for every other mark of your regard during my stay in Hertfordshire.

Mrs. Bennet wished to understand by it that he thought of paying his addresses to one of her younger girls, and Mary might have been prevailed on to accept him.

1）这里为什么不是were surprised？

2）这里的wished书上翻译成了“原希望”，原希望应该是had wished吧？所以，书上翻译成“原希望”是不妥的？

3）请老师讲一下这里为什么是might have been prevailed on, 而不是might be prevailed on 呢？这里用might have been prevailed on是对已经发生的事情推测还是虚拟语气呢？

4）这里的her's是什么？不懂。such an example as her's 可以理解成such as her's an example 吗？
