疑問：Due to unforeseen circumstances, the organizer of the "1000 Megawatt" co
ncert series suggested that event _____ until further notice.
A) postponed
B) postpones
C) be postponed
D) has postponed
看到suggested使用過去式，所以我也很直覺的在that後面的子句也選A過去式。
答案為C，有人能解釋的更為詳細嗎？
謝謝！
如果句子形式為 He insisted that ...... He told me that .... 是否that的後面的
動詞要用過去式呢？

謝謝樓上，想請問The evidence suggested that he "is" guilty. 這句話我就不能用was了嗎？
