A.having been canceled
B.had been canceled
C.having canceled
D.were canceled
要详解
答
我选的是B我也想知道为什么是A
答
D.
答
逗号后的句子是一句完整句子而且没有连词,所以前面那句就不是完整的句子,BD排除,
这里航班是被取消,所以C排除.选A
可是我记得老师说过have的现在分词不能做后置定语的啊、奇怪- -
LX、可是如果选B的话前后都是完整句子,需要连词,后面没有连词诶、、
答
楼上你错啦！！！！！！！！！！！！！！！！！！！！！！
因为是航班被取消、所以排除C
后面半句是had to go、所以前面半句的时态应该是过去的过去、也就是过去完成时、
所以答案应该是B
