“一拍即合”，汉语成语，意思是一打拍子就合上了曲子的节奏；比喻一相遇即十分合适、融洽，也比喻因情意相投，一下子就说到一起或结合在一起。与英文俗语“hit it off”意思相近，表示“form an immediate, positive connection with someone；quickly become good friends with someone”。
- 我就知道你和海丽会一拍即合，你们有太多共同点了。
I just knew you and Haley would hit it off—you two have so much in common. - 我很高兴你和我父亲一拍即合。他并不是个容易相处的人。
I'm so glad that you hit it off with my father. He isn't always the easiest person to get to know.
