overlap

★★
🇺🇸 /ˈoʊvɚlˌæp/
noun 编号: O01192 BNC #6707 COCA #8870
overlap 的核心意思是“部分重叠、彼此有一部分盖在一起”,可指位置、时间、范围或内容的重合;作名词时也指这种重叠状态。
💡 记忆钩子
想象两张纸只盖住彼此的一部分:它们在空间上“重叠”,引申为两个活动在时间上重合、两个范围有共同部分;在体育中,人数重叠形成进攻优势。
📝 学习建议
  • 先掌握“部分覆盖”和“时间或范围重合”这条主线,再记体育和专业用法。
  • overlap 不是“完全相同”或“完全覆盖”,重点是两者有一部分共同或交叉。
📖 中文释义
noun
  • core 重叠;交叠部分
    📖 指两个物体、范围或事物部分盖在一起或部分相同的状态。它强调“有一部分相交”,不表示全部一致。
    💡 常用句型是“there is an overlap between A and B”或“the overlap of A and B”。它既可指看得见的物体交叠,也可指计划、职责或内容的重合。根据语境可译为“重叠、交叉部分、重合”。
    intransitive transitive
    There is considerable overlap between the two training programs.
    这两个培训项目有相当多的内容重合。
  • common 进攻人数优势
    📖 在球类运动中,指进攻一方在某个区域暂时比防守一方多出球员,可以利用这种人数重叠突破防线。
    💡 常用搭配是“create/exploit/use an overlap”,也可说“a two-man overlap”表示多出两名进攻球员。这个意思主要出现在体育报道和比赛解说中。不要把这里的 overlap 只理解为队员站在一起。
    intransitive transitive
    The winger made a run to create an overlap on the right.
    边锋前插,在右路制造了人数优势。
  • rare 养老金重叠领取
    📖 在养老金语境中,指成员去世后的保证期内,其配偶或受扶养人的年金与成员原有福利同时支付。
    💡 常见于养老金、保险和福利文件,通常和“pension”或“annuity benefits”连用。它是制度术语,日常对话中不常用。阅读合同时要注意它表示支付时间重合,而不是两项福利内容相同。
    intransitive transitive
overlaps plural
verb
  • core 部分覆盖
    📖 指一个物体伸到另一个物体上方,并把它的一部分盖住;也可以不带宾语,表示两个物体彼此交叠。
    💡 常用结构是“A overlaps B”或“A and B overlap”,这里 overlap 本身不需要介词。若使用“overlap with”,通常是在强调与另一事物存在交叉。不要误用成表示完全盖住的词。
    intransitive transitive

    布的边缘盖过了桌子的一部分。

  • core 时间重合
    📖 指两个事件或活动在同一段时间发生,因此时间上有一部分相同。
    💡 常用结构是“A overlaps with B”或“A and B overlap”,也常说“the times overlap”。它既可描述短暂的时间冲突,也可描述两个阶段部分同时进行。不要理解成两个活动必须完全同时开始和结束。
    intransitive transitive

    我的早课和员工会议时间有冲突。
  • common 范围或内容相交
    📖 指两个事物在范围、特点、职责或功能上有共同部分;它们不必完全相同,只是在某些方面相近或相交。
    💡 常用结构是“A overlaps with B”或“A and B overlap in some areas”。“overlap in”后面接共同之处,如职责、主题或功能。翻译时要根据语境选择“重合、交叉、相近”而不是一律译成“覆盖”。
    intransitive transitive
    The responsibilities of the two departments overlap.
    这两个部门的职责有重合之处。
  • common 集合有共同元素
    📖 在数学中,指两个集合至少有一些相同的元素,因此它们的交集不是空集。
    💡 常用结构是“set A overlaps set B”或“the two sets overlap”。在较正式的数学表达中,也常用“have elements in common”说明具体共同元素。这里的 overlap 仍然沿用“有一部分共同”的核心概念。

    这两个数据集在几个类别上有共同部分。
  • rare 核苷酸序列部分相同
