问题补充：
Bocai Middle School, which is reported just two years ago, is now reowned throughout Hunan Province.
A. having established
B. to be established
C. being established
D. to have been established
答案：
A. having established
B. to be established
C. being established
(答案→)D. to have been established
解析：句意：据说是两年前建立的博才中学现在被湖南省重新拥有。这里使用的是句型：Sb/Sth be said/reported/announced 等后面应接不定式形式，可排除 A、C 项；由于 establish 发生在谓语 is reported 之前，并且“博才中学”与“建立”是被动关系，所以应选不定式的完成被 动式。选D。
