考研英语复习：长难句划分技巧及实例分析
长难句在考研阅读、完型填空和翻译中的出现频率很高，无论句子有多长、结构有多复杂，它都由一些基本的成分组成的。从结构来说，英语句子中，除了谓语之外，其它的成分均可以由从句或者非谓语动词来充当。从句本身是一个完整的句子，因此，从句与从句之间的关系可能包孕、套嵌，也可能并列、平行。从功能来说，英语有三大复合句，即:①名词性从句，包括主语从句、宾语从句、表语从句和同位语从句;②形容词性从句，即我们平常所说的定语从句;③状语从句。非谓语动词可以有自己的时态和语态(过去分词除外)，也可以跟自己的逻辑主语、宾语、状语等成分，构成一个非谓语动词结构。由于非谓语动词和从句的这些特点，使英语句子从理论上讲可以无限延长。
英语长句的分析方法：去枝叶，留主干。
1)划出句子中的定语从句和状语从句;
2)划出所有介词短语(位于be动词后的除外);
3)名词性从句看作一个整体,找出句中所有的谓语结构、非谓语结构、介词短语和从句的引导词;
4)非谓语动词结构看作一个整体;
5)找出全句的主语、谓语和宾语，即句子的主干;
6)分析从句的'结构和非谓语动词的内部结构。
长难句分析的步骤举例
经典例题(2001年考研完型填空第二段)
In a significant tightening of legal controls over the press, Lord Irvine, the Lord Chancellor, will introduce a draft bill that will propose making payments to witnesses illegal and will strictly control the amount of publicity that can be given to a case before a trial begins.
分析:
第一，划出定语从句和状语从句: that will propose making payments to witnesses illegal and will strictly control the amount of publicity /that can be given to a case /before a trial begins.
第二，划出介词短语：In a significant tightening of legal controls over the press
第三，句子的结构分析:
(1)主干结构是主语(Lord Irvine含同位语the Lord Chancellor)+将来时谓语(will introduce)+宾语(a draft bill);
(2)that引导的定语从句修饰draft bill,其中，will propose 是第一个谓语，making payments to witnesses illegal是一个动名词短语做宾语，在动名词短语内部，payments to witnesses做making的宾语，illegal是宾补;第二个谓语是will strictly control, the amount of publicity是它的宾语。that can be given to a case before a trial begins是孕含有一个时间状语从句(before a trial begins)的定语从句，修饰publicity。
请大家按照上述步骤认真分解以下的句子，并把分解后的句子读熟甚至背过，则基本上可以解决考研长难句问题。

2.The overall result has been to make entrance to professional geological journals harder for amateurs, a result that has been reinforced by the widespread introduction of refereeing, first by national journals in the nineteenth century and then by several local geological journals in the twentieth century.
结构分析: 本句主干部分是The ... result has been to make entrance ... harder for amateurs...; 第一个逗号后面是一个名词性短语，中心词是the result，后面是that引导的定语从句;此定语从句中包含两个并列状语，其结构为first by ... and then by ... ;
译文: 其总的结果是使业余人员的论文进入专业性地质学杂志更加困难，而审稿制度的全面引进使论文发表的难度进一步加大，这一制度开始是在19世纪的全国性杂志出现的，进入20世纪后也在一些地方性地质杂志实行。
3.Sad to say, this project has turned out to be mostly low-level findings about factual errors and spelling and grammar mistakes, combined with lots of head-scratching puzzlement about what in the world those readers really want.
结构分析: 本句主干结构是... this project has turned out to be ... findings ...; findings前面的mostly low-level是findings的修饰成分，后面的about ... 介词结构是宾语findings的宾语补足语;逗号后面的过去分词结构combined是状语成分，表示一种伴随的动作;
译文: 遗憾的是，这次调查的结果只获得了一些肤浅的发现，诸如新闻报道中的事实错误、拼写或语法错误，以及特别令人费解的困惑：读者到底想读些什么。
4.A lateral move that hurt my pride and blocked my professional progress prompted me to abandon my relatively high profile career although, in the manner of a disgraced government minister, I covered my exit by claiming "I wanted to spend more time with my family."
结构分析: 本句句子主干是A lateral move ... prompted me to ...; move后面是that引导的定语从句，修饰a lateral move, that在从句做主语;第一个逗号后面的是状语成分，两个逗号之间的部分是插入语;

结构分析: 本句主干结构是I have discovered ... + that引导的宾语从句;as引导的句子是伴随状语，可以看作是插入语;在that引导的宾语从句中，主语是两个动名词短语:abandoning ... and making ...，谓语是brings;
译文: 我已经发现(由于压力过大，凯尔茜已多次公开宣称要辞去《她》杂志编辑的职务，在这之后她也许会同样发现)：放弃“忙忙碌碌”的生活哲学，转而过一种“放慢生活节奏”的生活所带来的回报，比经济成功和社会地位更有价值。
6.Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.

7.
