用作介词 (prep.)

用作副词 (adv.)

用作形容词 (adj.)

在指“不久就要……”时，后通常接不定式，如about to start。也有接动名词，如about starting。但是不可再加表示时间的词，如不可说about starting at once；
指“大约”的意思时，表达方式有about ten，about half等。注意ten和half都是明确的数量，about不该用在“多少不定”的词前，如about more than ten，about less than half；
与at搭配使用时，about是副词，没有at时，about 是介词。句中可有at，也可没有，意思相同。
I went (at) about five (o'clock).
about + 不定式，表示“即将要去做某事”。
Don't go out now - we're about to have lunch.
about与动词go组成短语时，为副词，意为“着手做，从事”。

about，around，round: 这些词均有“在周围、在附近”之意。

about既可表静态，也可表动态。

around主要用于美国，静态或动态均可。

round主要用于英国，多半指动态。

almost，nearly，about，approximately，around，roughly: 这些副词均有“大约，差不多”之意。

almost指在程度上相差很小，差不多。

nearly与almost含义基本相同，侧重指数量、时间或空间上的接近。

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。

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。

around多用于非正式场合，常见于美国英语。

roughly指按粗略估计，常代替about。
