在考研英语中，长难句的精读能力至关重要。以下是对几个典型长难句的解析：
1. "The rapid development of technology has brought about numerous benefits, but it has also created many challenges."
解析：这句话的主干是"The rapid development of technology has brought about numerous benefits"，意为“技术的快速发展带来了许多好处”。而"but it has also created many challenges"则是转折，说明尽管有好处，但也带来了挑战。
2. "It is widely recognized that education plays a crucial role in the development of a nation, and it is essential for individuals to acquire knowledge and skills to adapt to the rapidly changing world."
解析：这句话的主干是"It is widely recognized that education plays a crucial role in the development of a nation"，意为“人们普遍认为，教育在国家发展中起着至关重要的作用”。后面跟着一个并列句，强调个人获取知识和技能的重要性。
3. "With the increasing globalization, more and more people are exposed to different cultures, which not only broadens their horizons but also enriches their lives."
解析：这句话的主干是"more and more people are exposed to different cultures"，意为“越来越多的人接触到不同的文化”。后面跟着一个非限制性定语从句"which not only broadens their horizons but also enriches their lives"，说明接触不同文化不仅拓宽了他们的视野，也丰富了他们的生活。
