Question

“The day is coming _____telegraph wires will be _____on to houses just like water or gas.” He said in his letter to his father.

A．that; lay

B．that; laid

C．when; laying

D．when; laid

Answer 1

D

第一空考查定语从句，先行词是the day，定语从句缺少时间状语，第二空考查动词lay摆放，过去时是laid，用被动式，句意是：他在给爸爸的信中写到，电话线将象水和电一样安装在家里的日子就要来了。选D。
