serve at the front

Make all customers stand in one long, snaking line—called a serpentine line—and serve each person at the front with the next available register.

让所有的顾客排成蜿蜒的长队——又称为蛇形队伍，用下一个可用的收银台为前面的每个人服务。

Another surprising find: the prefrontal cortex, though at the front of the brain, might actually serve as its central information hub that distributes information throughout the brain.

另一个惊人的发现是：前额叶皮质，虽然在大脑前端，但实际上可能是信息中枢的核心，负责将信息分配到整个大脑。
