疑问：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使用过去式，所以我也很直觉的在that后面的子句也选A过去式。
答案为C，有人能解释的更为详细吗？
谢谢！
如果句子形式为 He insisted that ...... He told me that .... 是否that的后面的
动词要用过去式呢？

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？
