选择题
The first prize winner _______, John was so disappointed that he felt unwilling to know the rest of the results.
A．announcing
B．announced
C．having announced
D．had been announced
答案
Ｂ
考察的独立主格结构。独立主格结构不是句子，但是它的作用相当于一个句子。本题的The first prize winner announced正是一个独立主格结构="After" The first prize winner was announced.结合句意可知B正确。句意：第一名被宣布以后，John如此的失望以至于他都不愿意去听其他的结果。
