exactly,precisely與accurately用法的區(qū)別?

1、exactly:通常有作比較的對(duì)象,比如：That,I think,was exactly his aim.我認(rèn)為,這正是他的目的所在。

這里就是與his aim進(jìn)行對(duì)比。

又如：Exactly right.And that reason is gravity.完全正確.根本原因是地心引力。

這里是與后面的And that reason is gravit進(jìn)行比較的。

2、precisely：一般作為精確的準(zhǔn)確的講時(shí)用在測量的場合。

當(dāng)做絲毫不差的,恰好的時(shí),指的是恰逢其時(shí)機(jī),沒有比較的意思。

比如：But that is precisely what is needed when there are so many alarming signs of overheating.不過,這恰恰是在種種警示經(jīng)濟(jì)過熱的跡象浮現(xiàn)時(shí)極有必要潑的冷水。

3、accurately.意思比較單一,主要指精確的,準(zhǔn)確的.通常用在測量或者評(píng)估,但是準(zhǔn)確程度要比precisely低。

比如：Individuals and corporations have strong economic incentives to accurately estimate the present and future earning capacity of the land.個(gè)人和公司都有強(qiáng)有力的經(jīng)濟(jì)手段來確切估計(jì)現(xiàn)在和將來土地的盈利能力。
