在考研英语二的复习过程中，长难句的解析与练习是不可或缺的一环。以下是一句典型的长难句练习：
"Although the rapid development of technology has brought about numerous benefits, it also poses significant challenges to the existing educational systems, which are struggling to adapt to the fast-paced changes in the job market."
这句话中，主句是"it also poses significant challenges to the existing educational systems"，其中"which are struggling to adapt to the fast-paced changes in the job market"是一个非限制性定语从句，修饰先行词"the existing educational systems"。此外，"Although the rapid development of technology has brought about numerous benefits"是一个让步状语从句。
通过这样的每日一练，可以帮助考生提高对复杂句型的理解和分析能力。
