Question

there was a knock at the door.

there was a knock at the door.it was the second time someone____me that evening
A had interrupted
B would have interrupted
C to have interrupted
D to interrupt
此题答案选择A 我选的是C 请问是为什么啊?

Answer 1

选择A,had interrupted
翻译：门口有人敲门,这已经是那晚第二次有人打断我了.
跟据句子时态,someone had interruped me that evening 是宾语从句.此句中,谓语应该是过去完成时态,而不能直接用不定式,所以 to have interruped 是错的.
