选B比较stop doing sth 和 stop to do sthstop doing sth.意为“停止做某事”即“不做某事了”，如： He stopped watching TV and began to read English.他停下来看电视，开始读英语。 stop to do sth. 意为“停下来原来做的事，做下面的事”，如： He watched TV for an hour; At 8 he stopped to do his homework. 他看了一个小时的电视，八点钟他停下来(看电视)去做作业。而句中 We’re listening to the news.可知该选择B希望能帮
