语法一直是英语学习的难题之一
合适的语法书是学好语言的基础和关键
下面⬇️就来推荐几本国内小众但国外流行的英语语法书，希望对你有帮助。
【The Ins and Outs of Preposition】
简介：Though written primarily for students of English as a Second Language, The Ins and Outs of Prepositions is also useful in remedial English courses on high school and college freshman levels. Unlike most languages - which usually have only a few prepositions to serve many different communication needs- English has dozen of them and almost none follows any clear, consistent set of rules. This book offers practical guidelines for correct usage, and provides hundreds of examples that incorporate all of the prepositions into familiar contexts. A total of 61 prepositions are examined.
大意为这是给英语为第二母语者撰写的介词用法书籍。书中详细介绍了61个介词的常用用法，并且配有相关例句解释。
【English Grammar in Use】
简介：《English Grammar in Use》是2011年剑桥大学出版社出版的一本全面、详细的语法参考书，作者为Raymond Murphy。本书适用对象是有一定语法基础的英语爱好者或学生，可自学或作为教学使用。
以上的两本书都非常适合自学学习。
