NO.1 限制性定语从句和非限制性定语从句的区别
一、限制性定语从句
它是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。这种从句与主句的关系十分密切，书写时不可用逗号分开。
(2024·新课标Ⅰ卷)I am writing to share with you an art class I had in a park last Friday.
学科网（北京）股份有限公司
我写信是想和你分享上周五我在公园里上的一堂美术课。
二、非限制性定语从句
它只是对先行词作附加补充说明，如果去掉，主句的意思仍然清楚完整。这种从句与主句的关系不是很密切，书写时往往用逗号分开。非限制性定语从句一般不用that引导。
(2024·浙江1月卷)Lastly，The “Stand Up and Stretch” exercise promotes a healthy and active lifestyle，which is essential for all of us.
最后，站起来做伸展运动促进了健康积极的生活方式，这对我们大家都至关重要。
