今天我们要学的词是 rudimentary.

rudimentary 的意思是初步的，起码的。 A groundbreaking new device is helping blind people perceive the world around them in a rudimentary fashion that can boost their quality of life. 一个具有突破性的新设备帮助盲人可以初步感知周围世界，从而提高他们的生活质量。

Many people aren't aware that Apple's iPadOS has rudimentary mouse support, although it's not very refined and it's buried deep in accessibility settings. 许多人都不知道苹果的iPad操作系统具有鼠标支持的基本功能，不过不是很完善，而且埋藏在辅助功能设置中。
