Restricted

“Restricted” 指因规则、安全或版权等原因缩小可用范围。restricted area 为禁入区;restricted access 需授权;饮食 restricted diet 表示受限食谱。语气比 limited 更强调“被外部规定挡住”。

  1. “This road is restricted to local traffic.” (此路仅限本地车辆通行。)
  2. “The file is in a restricted folder.” (该文件位于受限文件夹中。)
  3. “Membership is restricted to alumni only.” (会员资格仅限校友。)

“Restrict” 来自拉丁语 restrictus(绑紧),由 re-(回)与 stringere(拉紧)构成,与 strict、constrict 同源。

restrict + -ed:动词过去分词作形容词;名词 restriction(限制)。

机场 “restricted items” 指安检禁带物;政府 “restricted document” 涉密;游戏或软件 “age-restricted” 指年龄限制。

  • 固定搭配: “restricted access” (受限访问), “restricted zone” (禁区), “highly restricted” (高度受限)

strict 是“严”,re- 像往回拉紧——被拉紧的就是 restricted。

“Without a badge, he could not enter the restricted laboratory.” (没有胸牌,他进不了受限实验室。)
