问题 With the change of red lights, there are long queues of vehicles that wait while a few people who walk across the sidewalk.

选项 A、wait; walk
B、waiting; walking
C、waiting; walk
D、wait; walking

答案 C

解析第一处画线部分修饰前面的名词，相当于一个定语从句，又是表示主动和正在进行，因此应用动词现在分词形式，所以选waiting；while引导表示对比关系的从句，所以应是a few people walk across the sidewalk(一些人穿过了人行道)，所以答案为C。
