Question

They told us it was the second time that the volunteers _______ the nursing home.

A．visited

B．have visited

C．were visiting

D．had visited

Answer 1

D

试题分析：根据It is the second time +从句（从句中通常使用现在完成时态）；It was the second time +从句（从句中通常使用过去完成时态），其实在这个结构中，the second time 一般被看成先行词，后面是一个that引导的定语从句,故选D。
点评：固定词组及句型的考查是几乎每年高考都要涉及到，所以一定要牢记这些常用的词组及句型，需要用的时候，拿过来直接用就可以了。
