在雅思考試備考中我們不難發現，雅思閱讀中一篇好的文章用詞豐富、句式多變。雅思閱讀的文章均摘自西方報刊雜志，屬于原汁原味的外文資料，自然也會遵循著以上規律，所以雅思閱讀中對詞匯的考查萬變不離其宗，無非是對同義詞、反義詞、同根詞進行考核。
　　雅思閱讀詞匯換用例一：
　　原文：　In Europe, the obstacle has been conservative local authorities and developers who prefer to ensure quick sales with conventional mass-produced housing.
　　題目：Many developers prefer mass-produced houses because they...
　　答案：sell quickly
　　解析：原文和題目中的句意關鍵詞developer, prefer 均相同，但 “housing” 換成了 “houses”, 即同根詞的代換。 “they” 指代 “houses”， 又因為 “because” 應該引導從句，所以答案為動詞短語。 “quick sales” 對應的動詞短語為上述答案， 也就是說答案也是根據同根詞替換而來的。
　　雅思閱讀詞匯換用例二：
　　原文：While this includes complex kingdoms, as in Africa, and ancient empires, such as those of the Americas, the primary focus of attention in the twentieth century has been on small-scale societies.
　　題目：The twentieth-century collections come mainly from mainstream societies such as the US and Europe.
　　答案：FALSE
　　解析：原文與題目對比出現了一組反義代換詞 “small-scale societies” 和 “mainstream societies”.
　　雅思閱讀詞匯換用例三：
　　原文：Countries all over the world are actively promoting their wilderness regions to high-spending tourists. The attraction of these regions is obvious: by definition, wilderness tourism requires litter or no initial investment.
　　題目：The low cost of setting wilderness tourism makes it attractive to many countries.
　　答案：TRUE
　　解析：low cost=little or no initial investment; “attractive” 為 “attraction”的同根詞代換。
雅思閱讀詞匯換用例四：
　　原文：In their new location, the beekeeper will pay the farmer to allow his bees to feed in such places as orange groves.
　　題目： They transport their hives to orange groves where farmers (charge) beekeepers for placing them on their land. Here the bees make honey.
　　解析：這是劍橋上的一個填空題。不難看出，為了考查詞匯，題目對原文進行了同義句轉換，但是對主語和賓語進行了調換，所以謂語動詞也采用了相應的反義詞形式。
　　總之，詞匯換用這在雅思詞匯中是很平常的現象，但同時，這也是很多中國考生在平時容易忽視的細節，詞匯換用的技巧也不能通過單純的死記硬背雅思考試詞匯來掌握，所以同學們要注意平時針對性的練習。小編預祝同學們在雅思考試中取得好的成績。
