“初赛”常见的英文表达是 “preliminary round” 或 “preliminary contest”,也可用 “first round(of a competition)” 来表示。
preliminary round/contest: “preliminary”意为“初步的;预备的”,“round”和“contest”分别有“轮次”和“竞赛”的意思,整体表示竞赛中初步筛选的阶段,即初赛。例如:The winners of the preliminary round will advance to the semi-finals.(初赛的获胜者将晋级半决赛。)
first round(of a competition):直译为“竞赛的第一轮”,简洁明了地表达了初赛这一概念。例如:He performed well in the first round of the singing competition.(他在歌唱比赛的初赛中表现出色。)
