英語六級攻克閱讀關(guān)鍵句286. However, the ability to quickly work with

286. However, the ability to quickly work with figures in your head, to make rough but fairly accurate estimates, and to understand things like compound interest and basic statistics gives you a big lead on most people.

譯文　然而，能在頭腦中快速進行數(shù)字運算，能做出粗略但相當(dāng)正確的估計，能理解諸如復(fù)利和基本統(tǒng)計之類的事情，會讓你比許多人領(lǐng)先一大步。

點睛　本句的主干是...the ability...gives you a...lead。其中，三個to引導(dǎo)的并列不定式短語作ability的定語。

rough在句中意為“粗略的”，該詞還含有“粗糙的”之意。如：

My hands were rough with hard work. 我的雙手因繁重的工作而變得粗糙。

accurate意為“正確的，精確的”。如：

We must make sure that the information is accurate. 我們必須確保情報是準(zhǔn)確的。

give sb. a big lead on 意為“使某人比……領(lǐng)先一大步”，要表示“某人領(lǐng)先一大步”則可以說have/take a big lead。如：

I guessed that he would be the winner because he had a big lead. 我猜他會獲勝，因為他現(xiàn)在遙遙領(lǐng)先。

考點歸納　accurate、exact、precise、right、true和correct這幾個形容詞均含有“準(zhǔn)確的，正確的”之意，但它們在意義或用法上稍有區(qū)別。

accurate指與事實相符、無誤，即使不是精確對應(yīng)，偏差也不太大。如：

Anna is always accurate in punctuation and spelling. 安娜的標(biāo)點和拼寫總是非常精確。

exact側(cè)重質(zhì)和量的準(zhǔn)確，語氣比accurate稍強，指嚴(yán)格并完全地遵照事實或真理。如：

The exact date of my grandfather's birth is not known. 我爺爺出生的確切日期無人知道。

precise側(cè)重強調(diào)細節(jié)的精確無誤。如：

As well as being precise, the report being delivered was impersonal. 這份稿子不但用詞確切，而且不帶個人色彩。

right比較常用，可與correct換用，用于暗示道德、行動和理解等方面的正確。如：

It is right to send him the message. 給他發(fā)消息是正確的。

correct最為常用，通常指按一定標(biāo)準(zhǔn)或規(guī)則來衡量，沒有謬誤和差錯等。如：

I'm afraid that your commentary on this issue is not correct. 恐怕你對這個問題的評論是不正確的。
