本書所收錄的所有詞匯都屬于近些年考過的高頻單詞。為了讓讀者更加深刻地理解詞匯在實際中的運用，我們參考了美國當(dāng)代英語語料庫（Corpus of Contemporary American English）中主詞條出現(xiàn)的頻率，由低到高將詞頻分為1~5五個等級，供讀者參考。

單詞的中英文釋義。每個詞的釋義，并不是機(jī)械地搬運詞典釋義，而是結(jié)合具體考點語境做出對應(yīng)的解釋。英文釋義從《韋氏大學(xué)詞典》（Merriam-Webster’s Collegiate Dictionary）simple definition或full definition當(dāng)中選擇性摘錄，同時也參考了美國傳統(tǒng)詞典(American Heritage Dictionary)的釋義。

在GRE考試中，有一種題型叫做句子等價（sentence equivalence），俗稱“六選二”。其中絕大多數(shù)情況下是要求考生選擇一對同義詞，使句子的邏輯變得通順。基于實際考試，我們將考過的六選二詞對予以標(biāo)明，使所背即考點，性價比更高。

注意：(1)有的時候兩個詞在原考題語境中是一對正確選項（比如說inferable from與entailed by）拋離了語境可能不是一對同義詞，會使讀者產(chǎn)生困惑，不用糾結(jié)，做到面熟即可。

(2)有的時候“選”標(biāo)簽下給出的詞匯的詞性可能與主詞詞性不一致，不用在意。比如說precocious這個詞給出的“選”為maturity，是因為在考試中考的是precocious的名詞詞性，而陪考的同義詞也為名詞詞性。此類現(xiàn)象，并非筆誤，請讀者理解。

在2011年之前，老GRE時代考過一種題型叫做“類比反義”，我們摘取了此類題目中常考的反義詞選項。經(jīng)過對實際考試的分析發(fā)現(xiàn)，在老GRE時代考過的反義關(guān)系也會在新GRE填空題目中體現(xiàn)，比如說空格對應(yīng)某個元素取其反義詞，所以這個部分很有記憶的價值。
