Mr. Bennet's emotions were much more tranquil on the occasion, and such as he did experience he pronounced to be of a most agreeable sort; for it gratified him, he said, to discover that Charlotte Lucas, whom he had been used to think tolerably sensible, was as foolish as his wife, and more foolish than his daughter!

Jane confessed herself a little surprised at the match; but she said less of her astonishment than of her earnest desire for their happiness; nor could Elizabeth persuade her to consider it as improbable. Kitty and Lydia were far from envying Miss Lucas, for Mr. Collins was only a clergyman; and it affected them in no other way than as a piece of news to spread at Meryton.

Lady Lucas could not be insensible of triumph on being able to retort on Mrs. Bennet the comfort of having a daughter well married; and she called at Longbourn rather oftener than usual to say how happy she was, though Mrs. Bennet's sour looks and ill-natured remarks might have been enough to drive happiness away.

请教老师：

1) such as he did experience 整个是pronounce的宾语，宾语前置？did experience 是强调式？即did是强调谓语experience(d)吗？

2) be of a most agreeable sort，其中,   of a most agreeable sort 整个相当于形容词？  be of 具有...特性的意思吗？

3) might have been enough to...我看到网上有2种不同的翻译，

a) 不过班纳特太太满脸恶相，满口的毒话，也足够叫她扫兴的了。

b)  即使班纳特太太满脸恶相，满口的毒话，一点儿也没有扫了卢卡斯太太的雅兴。

显然，a)是推测用法，b)是虚拟语气。我认为是a）是错误的， b）是正确的。不知对否？
