### an invitation to dinner was soon afterwards dispatched;
然后用afterwards
派发邀请用 dispatch
### and already had Mrs.Bennet planned the courses, when an answer arrived which deferred it all.
这里it 指的是courses
这里用了倒装 强调already .这句话讲述了三个方面，一个强调already planned courses， 这时（when）一个答复过来， which推迟了courses。
### Mr. Bingley was obliged to be in town the following day, and consequently unable to accept the honour of their invitation.
be obliged to这是本文出现的第二次了
the following day. 指的是第二天，
the honour of their invitation. 邀请心意，好意。
### Mrs. Bennet was quit disconcerted.
disconcerted不安
disconcerted这个词有意思， concert是音乐会的意思，作为vi是协调的意思
### she began to fear that he might be always flying about from one place to another
这里about啥意思？
