我们在考研英语里，阅读题占了很大的分值比例，文章中的长难句常被用作命题点。有些考生因为看不懂长难句而遗憾丢分。长难句真的有那么难吗？可以怎样攻克长难句呢？其实，考生要了解清楚考研英语长难句是怎样构成的、有哪些类型，才会更清楚那些看起来很复杂的句子到底是怎么回事，才更能轻松看懂长难句。
　　考研英语长难句主要分为以下三种类型：
　　1 修饰成分复杂句子本不难，但是修饰成分多且长。从句(定语、状语、同位语从句等)修饰；介词短语修饰；不定式修饰。经常是在同一个句子里既有从句又有介词短语，而且还不止一个。
　　对于此类长难句，一定要注意抓住句子主干，先把主干给梳理清楚了，在此基础上再进行添枝加叶，这样才能知道这句话在说什么。
　　e.g.
　　As a discovery claim works its way through the community,the interaction and confrontationbetween shared and comPETing beliefs about the science and the technology involvedtransformsan individual's discovery claim into the community's credible discovery.
　　【句子分析】主语是the interaction and confrontation，谓语是transforms... into...，伴随状语是As a discovery claim works its way through the community，定语是between shared and competing beliefs about the science and the technology involved，修饰主语the interaction and confrontation。即:
　　(As a discovery claim works its way through the community),the interaction and confrontation[between shared and competing beliefs about the science and the technology involved]transformsan individual's discovery claimintothe community's credible discovery.
　　【参考译文】随着发现声明通过科学界起作用，科学和技术涉及到的共有的互动和冲突把个人的发现声明转化为科学界可信的发现。
　　2 大段的插入与或同位语插入语很长的句子，看起来很难，其实并不难理解。在阅读时，要先把句子主干找出来、不用理会插入语，要先从整体上去理解，之后再把插入语填充进去理解即可。
　　e.g.
　　The Internet — and pressure from funding agencies,who are questioning why commercial publishers are making money from government-funded research by restricting access to it— is making access to scientific results a reality.
　　【句子分析】这个句子里面出现了两个破折号，它们中间的内容and pressure... by restricting access to it就是插入语，在理解句子时可以先忽略这些内容。这样就很容易找出句子主干，也就是The Internet is making access to scientific results a reality。之后，再把插入语填充进去就可以完全看懂整个句子了。即:
