在考研英语中，长难句是考察考生语法理解和语言运用能力的重要环节。以下是对长难句的原创解析：
1. 理解句子结构：首先，要明确句子的主谓宾结构，找出句子的主干。例如，“It is reported that the new policy will greatly enhance the efficiency of the company.” 这句话的主干是 “the new policy will enhance the efficiency.”
2. 识别从句：长难句中往往包含多个从句，如定语从句、状语从句等。要准确判断从句的类型，明确其与主句的关系。例如，“The book, which was written by a famous author, is highly recommended by many readers.” 这里的定语从句修饰先行词 “the book”。
3. 掌握关联词：关联词在长难句中起到连接句子成分的作用。了解常见的关联词及其用法，有助于理解句子的逻辑关系。例如，“Although it was raining heavily, they still decided to go out for a walk.”
4. 关注时态和语态：长难句中时态和语态的使用较为复杂，要准确判断句子所表达的时间、动作和承受者。例如，“The experiment has been conducted by the researchers for several months.”
5. 积累词汇：长难句中往往包含一些生僻词汇，要加强对这些词汇的记忆和理解。例如，“The government has implemented a series of measures to reduce pollution.”
