❍ 公路两侧的山头上，峡谷里，突然地出现了敌人，射出了密集的炮弹、枪弹，虎啸狮吼般地叫喊着，从山头、峡谷、田野、村庄和小沟、小屋里～，直向公路上猛扑过来。(吴强《红日》186) Suddenly,on the hill tops and in the ravines flanking the highway,the enemy appeared and began swamping them with shells and bullets,then,with a ferocious roar,they burst in a swarm from hill-tops,ravines,fields,farmhouses,ditches and huts and hurled themselves straight towards the highway.
❍ 村子里响起一片锣鼓声，欢迎的人～。(张骏祥、赵拓《白求恩大夫》47)Drums boom,cymbals clash,people swarm out of the village.
