It was already two o'clock when I()London.A arrived B got C reached D came

问题描述:

It was already two o'clock when I()London.
A arrived B got C reached D came

C reached
别的都不能直接跟地点

答案为C,分析如下
A. arrive 为不及物动词,因此要说arrived in London
B 要加to, when I got to London (说话时人可能已经离开伦敦)
C reached为及物动词,后面直接加地点名词,选这个正确
D 后面也要加to
...when I came to London 说话时人还在伦敦
