第一期30天英语阅读习惯训练营Day 19：插入语（parenthesis）

训练营的小伙伴问到了插入语，今天就讲讲插入语（parenthesis）吧。

01 什么是插入语

thefreedictionary.com

插入语可以是单词、短语或从句，插入到句子/段落中，进行解释说明或补充说明。把插入语从句子中移除后，句子在语法上仍然正确。插入语一般会用逗号（commas）、破折号（dashes）、圆括号（parentheses）与句子区分开。

02 逗号、破折号、圆括号的用法

一般而言，逗号、破折号、圆括号是在插入语前后成对（in pairs）出现的。只有当插入语结束后句子也结尾了（用句点），才会用一个逗号/破折号。举例说明：

Lee, however has never found out what he loves to do.      ✘

Lee, however, has never found out what he loves to do.      ✔
