就算是序言吧 introductory

关于记忆英语单词，有很多很多种方法。构词法记忆法被认为是很有效的一种，许多市面上的词汇书都会采用。某次偶然浏览知乎，得知word power made easy 一书，读之 ，惊叹也，私以为可以算是构词法大成之作。当然，此书不仅仅涉及构词法，语法，词源多有涉及。然读此书，对基础要求可能较高，本人四级560，自知与985高才难比，普通人中也算勉强，读之仍觉困难，故整理其中构词法，以助好学之人。

There are many methods about learning vocabulary. Roots and suffixes are considered to help a lot about memorizing. I found a book,Word Power Made Easy by accident when I browsed zhihu.com . It introduces so many roots and suffixes very well. Of course,it is more than just roots and suffixes, containing grammar and origins of words.
However, it may be hard for someone to read this book. So I makes notes about it and share them to those who really love learning English.
