told us that they [ ]us to overcome any difficulties we would meet

题目

told us that they [ ]us to overcome any difficulties we would meet
选择哪一个并说明原因
A.help B.will help
C.help D.would going to help

答案

D .would going to help
从主句they told 可以看出是发生在过去的事,宾语从句要用过去的某个时态,从句中difficulties we would meet是在说话时还没发生的事,对于说话时来说是将来要发生的事,从句动词要用将来时
再看选项 只有D选项是过去时态,又表将来,所以选D
