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尤指对须计算才能得到准确数值的事物进行估算，如cost（成本）。judge多与distance、depth、speed搭配，指对需要测量才能得出具体数据的距离、深度、速度等方面进行判定。estimate常指根据已有信息，对所需的费用和时间等不能确切计算的概念进行仔细评估。judge常指凭借经验迅速对距离和速度作出判断，而不是对所有的信息仔细考量后再作出判定。■ reckon [transitive, often passive] to estimate an amount or time approximately 估算；估计◆The age of the earth is reckoned to be about 4 600 million years.估计地球的年龄大约为46亿年。◆They reckon (that) their profits were down by 30%.他们估计利润减少了30%。◆The trip was reckoned to take over two days.这次旅行估计要花两天多。ⓘ An amount or time that is reckoned may be more approximate than one that has been estimated. * reckon对时间的估算要比estimate更准确。■ calculate [transitive] to guess sth or form an opinion by using all the information available 预测；推测◆It's impossible to calculate the extent of his influence on her.无法估计他对她的影响有多大。◆Environmentalists calculate that hundreds of plant species may be affected.环保主义者预测数百种植物可能受到影响。 see also calculate ⇨ calculate ■ gauge (NAmE also gage) / /geɪdʒ/ / [transitive] (rather formal) to estimate the level or amount of sth approximately 估计，估算（水平或数量）◆We were able to gauge the strength of the wind from the movement of the trees.我们可以根据树的摆动估算风力强度。 see also gauge ⇨ criterion noun ■ figure [transitive] (especially NAmE, rather informal) to estimate the amount, cost or age of sb/sth, especially approximately 估计，估算（数量、成本或年龄）◆If we can figure roughly how much it will cost, we can decide what to do.如果我们能大致估算出费用是多少，就能决定怎么走下一步了。ⓘ In American English figure can also be used to talk about calculating sth exactly. 在美式英语中，figure还可表示准确计算。 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 推断；推知；推算◆The figures were obtained by extrapolating from past trends.这些数据是根据过去的趋势推断出来的。◆These results cannot be extrapolated to other patient groups.这些结果不能够推及到其他患者群。▸ extrapolation noun [uncountable, countable] ◆Their age can be determined by extrapolation from their growth rate.它们的年龄可以从它们的生长速度来推定。 |
