approximately

漢語翻譯

詞意辨析：

almost, nearly, about, approximately, around, roughly

這些副詞均有“大約，差不多”之意。
almost: 指在程度上相差很小，差不多。
nearly: 與almost含義基本相同，側重指數量、時間或空間上的接近。
about: 常可分almost和nearly換用，但about用於表示時間、數量的“大約”時，實際數量可能多也可能少。
approximately: 多用於書面語，指精確度接近某個標準以致誤差可忽略不計。
around: 多用於非正式場合，常見於美國英文。
roughly: 指按粗略估計，常代替about。
