改错题67.Good news was sometimes released prematurely, with the American recapture of the port having announced half a day before the defenders actually surrendered.
【正确答案】
B
【答案解析】这句话的意思是：好消息有时会过早地被公布，美国人在守军实际投降前半天就宣布已经重新夺回港口。这句话的前半句为主句，后半句采用了独立主格结构，所以不能用谓语形式，C和D可排除。逻辑主语the American recapture of the port与动词announce构成被动关系，故排除A项，过去分词announced为正确答案。答案为B。
