这里说的wave被stage (步骤)或step I可以解释为(工序)。但是,它的特点是指一个伴随着巨大胁迫的阶段。换句话说, first wave是指第一次进攻。之后,如果你撤退并再次攻击,它就会成为second wave示例: We had a sale today. The first wave of customers came in at lunchtime. The second wave came in the afternoon. (今天有打折活动。第一批顾客在午餐时间来。第二批在下午来。) 示例:一阵A wave of happiness suddenly came over me. Then I was sad again. (突然欣喜若狂。然后我又变得沮丧。)
