字面拆解：
`narrow` 作为动词，意为“使变窄；缩小”；
`gap` 意为“差距；间隙；隔阂”；
`between…and…` 连接两个对比的对象。
因此，整个短语的意思是：缩小/弥合…与…之间的差距（或隔阂）。
该短语是正式且高频的表达，常用于社会议题、政策讨论、数据对比、人际关系等场景，强调通过行动减少两个对象间的差异。
`narrow the gap between A and B`
`A`和`B`需是同类的对比对象（如群体、区域、数据、概念等）；
可根据语境在`gap`前添加修饰词（如`economic/social/educational`等），明确“差距类型”。
以下是不同场景的典型用法：
缩小贫富差距：`narrow the gap between the rich and the poor`
例：The new tax policy aims to narrow the gap between the rich and the poor.（新税收政策旨在缩小贫富差距。）
缩小城乡教育差距：`narrow the gap between urban and rural education`

例：Providing free Wi-Fi in rural areas can narrow the gap between people with and without internet access.（在农村提供免费Wi-Fi能缩小有网与无网人群的数字鸿沟。）
`narrow` 是及物动词，后面直接接`the gap`，无需加介词；
`between…and…` 连接的两个对象需逻辑对称（如“富人与穷人”“城市与农村”，而非“苹果与吃苹果”）；
若要表达“差距已经缩小”，可改用完成时：`The gap between A and B has been narrowed.`（A与B之间的差距已被缩小。）
"narrow the gap between…and…"是一个精准表达“缩小差异”的短语，核心是通过行动减少两个对比对象的差距，适用于从政策到日常的各类场景。掌握其搭配和语境，就能灵活运用啦！
