Accompany这个词儿啊，说白了就是"陪着"、"跟着"的意思。比如说"我陪你去逛街"，就可以说"I'll accompany you shopping"。
在音乐里头，accompany就是"伴奏"的意思。比如"她弹钢琴给歌手伴奏"，就是"She accompanied the singer on piano"。
这词儿还有几个别的意思呢：
1. 表示"伴随"、"同时发生"。比如说"大雨伴随着强风"，"Heavy rain accompanied by strong winds"。

小贴士：这个词儿在口语里经常用，但是要注意搭配哈。比如说"陪朋友"用accompany就有点正式了，日常说hang out with更地道。
