一、詳細(xì)釋義：


adv.

近似，大約，近乎


例句：

The plane will be taking off in approximately five minutes.

飛機(jī)大約五分鐘后就起飛。


例句：

The journey took approximately two weeks.

旅行大約用了兩周。


二、詞義辨析：


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(cè)重指數(shù)量、時(shí)間或空間上的接近。 about?？煞謅lmost和nearly換用，但about用于表示時(shí)間、數(shù)量的“大約”時(shí)，實(shí)際數(shù)量可能多也可能少。 approximately多用于書面語，指精確度接近某個(gè)標(biāo)準(zhǔn)以致誤差可忽略不計(jì)。 around多用于非正式場合，常見于美國英語。 roughly指按精略估計(jì)，常代替about。
