我来补答
正解是A.
解题思路,句中插入了时间状语从句when they are talking to us,解题时可以先把它忽略掉
——— others (主语) is usually considered ( 谓语) rude and inappropriate.( 主语补足语)由此可见句子缺少主语,只能先排除B,其他三个都是非谓语动词,动词不定式也可以作主语,但表示的是具体的行为,而不是习惯性的行为,况且 interupt 和others 之间存在逻辑主动关系,而不是被动关系,所以 D也是错误的,having done 表示发生在谓语动词之前且已经完成的动作,在别人说话时打断他们被认为是不礼貌和不恰当的,应该是和谓语动词同时发生的动作,且句中有usually ,表明是习惯性的行为,故用动名词的一般式,interupting
