背单词一直是不少烤鸭们很抗拒的事情，因为常常感觉付出与收获不成正比，辛辛苦苦背的单词，没过几天就忘得一干二净，在写作中想用的时候要么怎么也想不起来，要么拼不正确。其实高分词汇不一定要是看起来很难，或者考官都不认识的单词，有很多我们熟悉的简单词汇会有不常用的义，因为单词本身不难，所以记起来用起来会轻松很多。
先给大家科普一下CEFR: The Common European Framework of Reference for Language，雅思成绩单最后一栏显示的就是根据欧洲共同语言参考标准匹配的英语水平等级，分为A1入门级、A2初级、B1中级、B2中、C1、C2精通级六个级别。用过Cambridge Dictionary，且细心的同学会发现单词的每个意思也会有一个匹配的CEFR级别。下面就带大家一起来见识见识那些熟悉单词的陌生义，以及可以如何在雅思写作中运用。每个单词会给一个例句，可以尝试使用给出的单词自行翻译，然后对照给的参考版本。
