SAT詞彙記憶口訣“改變記憶單位 賦予你的理解 構建詞語聯絡”;也就是通過詞根詞綴、諧音記憶、聯想記憶、分拆組合等方法將一個單詞分解開。輕鬆突破詞彙難關、從容應對SAT考試。請看以下SAT高頻詞彙：
fallacious adj. 錯誤的,謬誤的
首先看該詞中含有我們熟悉的單詞fall, fall的基本意思：掉下來，摔跟斗;人生難免摔跟斗，犯錯誤;所以英文中含有fall有錯誤的意思，大家可以聯絡下相關詞彙false, fault, faulty; 其實fallacious 來自名詞fallacy (錯誤，謬誤)，fallacy 可以理解為fall+acy, -acy 一般是表示名詞的字尾。順帶擴充下fallible(容易犯錯的)infallible(永不犯錯的)。大家知道美語裡面fall還有秋天的意思，為什麼呢?秋天果實成熟了，就要fall(掉下來)了.
consensus n. 共識
這個詞一看三部分 con-, -sens-,-us. 大家知道英文中co系列的字首指的是together 一起的意思，包括co-, con-, com-, cor-等形式。Sense 本身也是一個單詞,表示‘感覺’等意思。-us做字尾一般表示名詞，如status(地位)。所以整個詞consensus表示大家都感覺是一致的，共識。英文中-sens- 和 –sent- 作為詞根都表示“sense”。更多單詞如：sensible, sensitive, consent(同意)，resent(反感)，sentiment(情感), sentimental(多愁善感的), presentiment(預感) 等。
discordant adj 不和的 不調和的
同樣該詞由三部分構成;dis-表示否定;-cord-作為詞根表示“心”，-ant-一般是形容詞或名詞結尾。大家可以聯想下core(核心)，concord(協和)，accord(一致)，dicord (不和)，其實英語中-card-也可表示“心”;electrocardiogram大家能猜到意思嗎?心電圖。
embellish vt 美化，裝飾
em-字首，表示外面outsite, 英文中ex-相關的字首很多，表示outside, 或者說當我們看到e開頭的單詞基本都包含這個意思。中間這個-bell-聯絡一下belle (美麗，美女) 到處能看到百麗的廣告“因為百麗，所以美麗”。百麗的英文標誌為belle. –ish 很好理解，作為字尾表示動詞、名詞、形容詞都有可能。如finish, establish, diminish等等。
總之，當我們拿到一個生詞的時候，一定要看看其中有沒有哪些部分是我們已知的，要善於從部分推匯出整個單詞的意思。當然，熟悉一定量的詞根是必要的，下一講，我們將一起探討SAT高頻詞彙裡面最重要的幾十個詞根。
