詞匯題就是從具體的語境中理解詞匯。鑒于英語單詞的一詞多義，所以準(zhǔn)確理解某一個單詞的意思需要依據(jù)語境。這里的語境就是我們所要閱讀的文章的上下文。一般來說通過上下文推斷或者猜測詞意，上下文中可以利用的信息為，例句，對比詞，同義詞，反義詞或者其他段落的解釋等。此外，文章中一些特定搭配關(guān)系也可以幫助我們找到正確的答案。IBT的詞匯題考的都是近義詞，題目常見的問法如下：The word (or phrase) X is closest in meaning to ……, the word (or phrase) x could be best replaced by X.做這類題目，判斷所考察詞匯在原句中與其周圍詞匯的關(guān)系是關(guān)鍵，此外還要注意所考察詞匯的詞性。下面我們來看看常見的五種可以幫助我們迅速找到詞匯題答案的特殊關(guān)系。
    一、五類常見的詞匯關(guān)系：
    1. 直接反義關(guān)系—該詞前或后出現(xiàn)的內(nèi)容提示我們是反義關(guān)系。 表示相反概念的詞語如下rather than，instead，unlike，contrast，on the contrary.
    例如:
    The main conflict in the novel is between a mother who places a high value on hard
    work and honor and a son who repudiates his mother's values instead preferring the easier path to fortune and celebrity
    The word repudiates in the passage in closest in meaning to __
    A) refuses to accept B) lives up to C) tries to understand D) makes the best of
    假如repudiates我們不認(rèn)識，從后面的小詞 instead 這個詞判定兒子和***價值觀念是相反的，由此信息看四個選項(xiàng)，你會發(fā)現(xiàn)只有A選項(xiàng)帶有否定的意味
    2.并列關(guān)系：并列關(guān)系詞如下： and，not only ……but also，as…as，and，both … and，either… or neither… nor
    例如:
    She embarked on her career by working as a newspaper reporter in Wisconsin and soon began writing novels.
    The phrase embarked on in this sentence is closest in meaning to
    A) took a trip to B) started out on C) improved upon D) had a opinion about
    回到原文看embarked on周圍的詞語和它在這個句子中的作用。在這句中關(guān)健詞 and 其后出現(xiàn)soon began告訴我們前后方向是一致的，前面也必然和began有關(guān)，所以本題目的正解是B.
    3.解釋關(guān)系:后面的句子或短詞,單詞來解釋前面的詞。常見的標(biāo)志詞:Contribute to，be responsible for，account for，since ，therefore ，for，because，in which等
    例如:
    His big break came with the novel So big(1924) ,which was awarded the Pulitzer in literature.
    The word break in this sentence could best be replaced by ___
    A) Rupture B) revelation C) opportunity D) rest
