Estimate is used especially to talk about things such as costs, which you would have to calculate to know exactly. Judge is used more for things such as distances, depths and speeds, which you would have to measure to know exactly. People often estimate future costs and lengths of time which cannot be calculated exactly, by thinking carefully about what is likely, given the information that they have. People often have to judge distances and speeds quickly, not by thinking carefully about all the available information, but by using their past experience as a guide. * estimate尤指對須計算才能得到準確數值的事物進行估算，如cost（成本）。judge多與distance、depth、speed搭配，指對需要測量才能得出具體數據的距離、深度、速度等方面進行判定。estimate常指根據已有信息，對所需的費用和時間等不能確切計算的概念進行仔細評估。judge常指憑借經驗迅速對距離和速度作出判斷，而不是對所有的信息仔細考量後再作出判定。■ reckon [transitive, often passive] to estimate an amount or time approximately 估算；估計◆The age of the earth is reckoned to be about 4 600 million years.估計地球的年齡大約爲46億年。◆They reckon (that) their profits were down by 30%.他們估計利潤減少了30%。◆The trip was reckoned to take over two days.這次旅行估計要花兩天多。ⓘ An amount or time that is reckoned may be more approximate than one that has been estimated. * reckon對時間的估算要比estimate更準確。■ calculate [transitive] to guess sth or form an opinion by using all the information available 預測；推測◆It's impossible to calculate the extent of his influence on her.無法估計他對她的影響有多大。◆Environmentalists calculate that hundreds of plant species may be affected.環保主義者預測數百種植物可能受到影響。  see also calculate ⇨ calculate ■ gauge (NAmE also gage) geɪdʒ [transitive] (rather formal) to estimate the level or amount of sth approximately 估計，估算（水平或數量）◆We were able to gauge the strength of the wind from the movement of the trees.我們可以根據樹的擺動估算風力強度。  see also gauge ⇨ criterion noun ■ figure [transitive] (especially NAmE, rather informal) to estimate the amount, cost or age of sb/sth, especially approximately 估計，估算（數量、成本或年齡）◆If we can figure roughly how much it will cost, we can decide what to do.如果我們能大致估算出費用是多少，就能決定怎麽走下一步了。ⓘ In American English figure can also be used to talk about calculating sth exactly. 在美式英語中，figure還可表示準確計算。   see also figure ⇨ calculate ■ extrapolate ɪkˈstræpəleɪt [intransitive, transitive] (formal) to estimate sth or form an opinion about sth, using the facts that you have now and that are valid for one situation and supposing that they will be valid for the new one 推斷；推知；推算◆The figures were obtained by extrapolating from past trends.這些數據是根據過去的趨勢推斷出來的。◆These results cannot be extrapolated to other patient groups.這些結果不能夠推及到其他患者群。▸ extrapolation
