考研英语中的长难句通常包含多个从句和修饰成分，结构较为复杂，理解起来有一定难度。以下是一些经典的考研英语长难句：
句子1
内容："In the idealized version of how science is done, facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work."
解析：本句的主干为"facts are waiting to be observed and collected"，其中包含一个由"who"引导的定语从句修饰"researchers"。这个句子结构清晰，但整体含义需要仔细分析才能完全理解。
句子2
内容："That suggests a lot can be achieved by using artificial intelligence in hiring and promotion decisions, providing the programming is done correctly and focuses on candidate qualifications."
解析：本句的主干为"That suggests a lot can be achieved"，后面跟着一个条件状语从句"by using artificial intelligence in hiring and promotion decisions, providing the programming is done correctly and focuses on candidate qualifications"。这个句子通过"providing"引导的现在分词短语作为条件状语，增加了句子的复杂性。
句子3

句子4

解析：本句以"If"开头，引导一个条件状语从句，其中包含一个由"as"引导的方式状语从句。这个句子结构较为复杂，但通过逐步分析可以理解其逻辑关系。
句子5

解析：本句的主干为"The potential evolution of today's technology is dazzlingly complicated"，后面跟着一个并列句"and its social consequences"，并且最后通过"it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage"提出一个观点。这个句子通过并列结构和长距离依赖，使得句子含义较为深远。
