Question

Nearly 56 percent of Chinese believe that traffic order got even worse after tightened traffic regulations ______at the beginning of 2013.

A．have been adopted	B．were adopted
C．adopted	D．had adopted

Answer 1

B

试题分析：句意：自2013年初实施强化交通规则后，将近56%的中国人认为交通秩序变得很糟糕。。traffic
Regulations和adopt是被动关系，所以排除CD，而时间是2013年初，用一般过去式的被动语态，所以选B。
