B. being questioned
C. to be questioned
D. having questioned
网友回答
A. questioned
B. being questioned
C. to be questioned
D. having questioned
解析：选A。题干的意思是：“刚才被警察问询的证人对打架作出了不同的描述。”该题考查的是非谓语动词作后置定语。那些证人是“被问询”的，所以要用question的被动形式，故可以排除D；由句中的just now和gave very different descriptions不难得知“问询”这一动作发生过了，所以要用动词的过去分词作定语；B项表示“正在被问询”；而C项则表示“将要被问询”，动作还没发生；所以B、C两项均不符合题意。
