第1、2组词是经常被混淆的四个单词，两两组合进行对比，会给掌握单词带来更高的精准度。

E.g. He showed a marked antipathy to foreigners.
apathy: lack of interest; indifference 缺乏兴趣;漠不关心
E.g. My parents do not feel apathy about the election.
这一组词大家可以用词根词缀发来区别，path-作为词根是“情感”的意思，anti-作为前缀是“相反，对抗”，而a-是“不、无、非”的意思，相关单词有sympathy, empathy等。
4. derive vs. deride
derive: originate from sth; get sth from sth源自，源于;得到获取
E.g. Thousands of English words derive from Latin.
deride: mock sb/sth 嘲笑，嘲弄
E.g. They derided his effort as childish.
derisive这个单词出现在阅读中经常被当做是derive的形容词性理解，其实是deride的形容词，意思为“嘲笑的，嘲弄的”，例如derisive laughter。
5.exhausted vs. exhaustive
exhausted: very tired 精疲力尽的
E.g. After a ten-mile hike, everybody is exhausted.
exhaustive: very thorough; complete 详尽的;彻底的

6. imprudent vs. impudent

impudent: very rude and disrespectful 粗鲁的;放肆的;无礼的;不尊重的
E.g. Tom is an impudent child who never listens to his parents.
在记这组词之前，最好先记住prudent这个单词，它本身就是“谨慎的，审慎的”意思，在其加上im-这个表否定含义的前缀，意思就很容易得出了。
7. callow vs. callous
callow: immature and inexperienced 既不成熟又无经验的;乳臭未乾的
callous: cruelly insensitive or unsympathetic 冷酷无情的;无同情心的

10. impassive vs. impassioned
impassive: showing no sign of feeling 无表情的，无动于衷的
E.g. The accused sat impassively as the judge sentenced him to ten years in prison.
impassioned: showing strong deep feeling 充满激情的;热烈的
E.g. He made an impassioned plea for mercy.
同第3组词相似的地方是这一组词里面含有pass-表“情感”含义的词根，im-表“不无、非”，所以impassive就是“无表情的，无动于衷的”意思。而后者中含有的“passion”其本身就是“激情，热情”的意思。
11. adapt vs. adept
adapt: make sth suitable for a new use, situation, etc; modify sth 使某事物适合於新的用途﹑情况等;修改某事物
E.g. These styles can be adapted to suit individual tastes.
adept: expert or skilful in (doing) sth 对(做)某事物内行的，熟练的
E.g. She’s adept at growing roses.
这一组词中adapt也经常容易与adopt混淆，adopt意思为“采纳，收养”。
12. indigent vs. indigenous
indigent : poor 贫穷
indigenous: native 土生土长的，当地的
E.g. Kangaroos are indigenous to Australia.
13. presumptive vs. presumptuous
presumptive: based on reasonable belief; probable基于合理之推测的;可能的
E.g. It is absurd that he was sentenced to death based on presumptive evidence.

ingenuous: open, innocent 坦率的，不隐瞒的，天真的
E.g. That kid gives me an ingenuous smile.
这一组词，可以利用另外两个单词帮助记忆：genius和genuine。前者意思为“天才”后者意思为“真的，真诚的，非人造的”。ingenious从发音和词形上与genius相近，而ingenuous 和genuine 相近。
15. discreet vs. discrete
