approximately, about

approximately最接近的，误差极小

about大致接近，误差可大可小；

almost, approximately, about, nearly, roughly, around

这组词都有“大约，差不多”的意思，其区别是：

almost指在程度上相差很小，差不多。

approximately多用于书面语，指精确度接近某个标准以致误差可忽略不计。

about常可分almost和nearly换用，但about用于表示时间、数量的“大约”时，实际数量可能多也可能少。

nearly与almost含义基本相同，侧重指数量、时间或空间上的接近。

roughly指按精略估计，常代替about。

around多用于非正式场合，常见于美国英语。
