SAT考试虽然对词汇量要求巨大，但对词汇深度要求较低，考生应熟悉一定量的词根，善于从部分推导出整个单词的意思，通过短期的强化记忆突破SAT词汇。
SAT考试的特点，要求词汇量大，但是对词汇掌握的深度教低，完全可以通过短期的强化记忆突破词汇1万，轻松应对SAT考试，尤其是词汇部分的考试。SAT词汇记忆口诀“改变记忆单位 赋予你的理解 构建词语联系”；也就是通过词根词缀、谐音记忆、联想记忆、分拆组合等方法将一个单词分解开。轻松突破词汇难关、从容应对SAT考试。请看以下SAT高频词汇：
fallacious adj. 错误的,谬误的
首先看该词中含有我们熟悉的单词fall, fall的基本意思：掉下来，摔跟斗；人生难免摔跟斗，犯错误；所以英文中含有fall有错误的意思，大家可以联系下相关词汇false, fault, faulty; 其实fallacious 来自名词fallacy (错误，谬误)，fallacy 可以理解为fall+acy, -acy 一般是表示名词的后缀。顺带扩充下fallible（容易犯错的）infallible(永不犯错的)。大家知道美语里面fall还有秋天的意思，为什么呢？秋天果实成熟了，就要fall(掉下来)了.
consensus n. 共识
这个词一看三部分 con-, -sens-,-us. 大家知道英文中co系列的前缀指的是together 一起的意思，包括co-, con-, com-, cor-等形式。Sense 本身也是一个单词,表示‘感觉’等意思。-us做后缀一般表示名词，如status(地位)。所以整个词consensus表示大家都感觉是一致的，共识。英文中-sens- 和 –sent- 作为词根都表示“sense”。更多单词如：sensible, sensitive, consent（同意），resent（反感），sentiment（情感）, sentimental（多愁善感的）, presentiment（预感） 等。
discordant adj 不和的 不调和的
同样该词由三部分构成；dis-表示否定；-cord-作为词根表示“心”，-ant-一般是形容词或名词结尾。大家可以联想下core（核心），concord(协和)，accord（一致），dicord (不和)，其实英语中-card-也可表示“心”； electrocardiogram大家能猜到意思吗？心电图。
embellish vt 美化，装饰
em-前缀，表示外面outsite, 英文中ex-相关的前缀很多，表示outside, 或者说当我们看到e开头的单词基本都包含这个意思。中间这个-bell-联系一下belle (美丽，美女) 到处能看到百丽的广告“因为百丽，所以美丽”。百丽的英文标志为belle. –ish 很好理解，作为后缀表示动词、名词、形容词都有可能。如finish, establish, diminish等等。
更多例词，下次分享。
总之，当我们拿到一个生词的时候，一定要看看其中有没有哪些部分是我们已知的，要善于从部分推导出整个单词的意思。当然，熟悉一定量的词根是必要的，下一讲，我们将一起探讨SAT高频词汇里面最重要的几十个词根。
