Question

关于REGRET的英语单选.
I regret--you that all the rooms in our hotel are reserved for the conference tobe held in our town tomorrow.
A.telling
B.to tell
C.being told
D.to have told
查到它可接VING或THAT,但也有接TO DO表正式的,

Answer 1

regret to do sth.很遗憾地／抱歉地做...（事情还没有做）
regret doing sth.很遗憾/后悔做了...（事情已经做过.）
regret+that+从句（从句里是指具体后悔什么事）
因此选B 意思是很遗憾地告诉你房间已被预订了,而告诉你（tell）是发生在regret之后的
