英语用 come 表示朝说话人所在位置移动，用 go 表示远离说话人；汉语“下来/下去”只按垂直方向区分，所以容易误用 go。说话人已在楼下，对方下楼是向说话人靠近，因此要用 come down。

易错句子He fell down from his bike and hurt his knee.
正确表达He fell off his bike and hurt his knee.
汉语“从自行车上摔下来”里带“下来”，但英语表示从某个表面或物体上脱离坠落要用 fall off sth；fall down 只表示自身倒下、跌倒，不能接 from 表示从物体上掉下来。
副词 down 的核心义是“从高处到低处、向下”，其直接反义词为 up（向上）。当 down 表示数量、水平或强度“减少、降低”时，反义同样是 up（上升、提高）。但 down 表示“沿路往前、直行”或“向南”等义时，up 并非严格反义词。
方向相反的一对副词：down 表示从高处往低处、朝底部移动，up 表示朝更高处移动。二者都作副词时只能按实际移动方向选一个，不能互相替换。
below 说的是静止的较低位置，常作介词或副词；down 说的是向下移动的方向或过程。描述“在下方”用 below，描述“向下方”才用 down。
