【雅思培训-阅读】雅思阅读长难句化繁为简

雅思考试的阅读部分，对于很多人来说，在很短的时间里完成800-1200词汇的阅读和解答是有一定难度的。若想快速的、高效率的完成题目解答也是有一定技巧的。下面小编为大家做了详细介绍，希望对大家备考雅思阅读有帮助。

　　英语的基本句式结构其实很简单：主谓宾和主系表。主谓宾是“谁-做-什么”，例如：比如“羊吃草”;“洁白可爱的小绵羊蹦蹦跳跳欢快活泼地在一望无垠的广阔草原上幸福愉快地吃着鲜嫩碧绿的青草”一样也是主谓宾，只不过多了一些修饰的词，句子的核心意思还是“羊吃草”。主系表是“谁-是-什么”，同主谓宾一样。在阅读中我们要很快的找出核心句子，不用每句话的意思都懂，但要知道这句话要表达的核心意思，即找到主谓宾或主系表的主体。

　　针对这两种句式结构抓主干，即把复杂的长难句转化成简单的句子。

　　主谓宾结构：寻找谓语动词

　　主系表结构：寻找系动词

　　也就是说，无论哪种句式，我们都要在心里默念寻找动词这个原则，以模糊匹配的方式来对应最有意义的那个动词，进而确认动词之前的主语和动词之后的宾语或表语。

　　一个句子之所以能够拉长，除了在一个简单句中加上许多修饰成分之外，还有可能是长出了枝干—也就是加了从句，或者是由连词和平衡结构把若干简单句合并在了一起。雅思长难句最频繁出现的情况包括如下几种：

　　定语从句：that, which(介词+which), who,…

　　状语从句：v+ing

　　寻找平衡结构：三大连词 and/or/but，

　　not only…but also…

　　not…but…

　　no more/longer/less …than

　　as…as

　　not so …as… . . .

　　还有一种特殊主系表值得单独说一说：

　　There be句型：寻找中心词

　　这个句型之所以特殊，是因为系动词和表语都已经以倒装的形式给出来了，欠缺的只是一个主语中心词而已，因此我们看到了there be开头的句子，一定先集中精力寻找到那个中心点。此外，这个句子是一些同学在雅思作文考场上易犯错误的地方。在时间紧迫的压力下，可能会有同学不自觉地受到了中文思维的影响，写出诸如“There are many people do something.”此类的句子，如果在模拟考试的时候发现自己曾经犯过这类笔误，建议大家在考场上给自己留出1、2分钟的检查时间来。检查方法也很简单，把there be两个词遮住，如果剩下的部分还能读出一个完整的句子来，则原本的句子必定是有问题的，可以迅速把there be这两个词擦掉。

　　除了be动词外，还有一些there be形式的变体：

　　There come/comes/came

　　There appear/appears/appeared

　　There emerge/emerges/emerged

　　There may/might be

　　There can/could be

　　There happen to be

　　There used to be

　　There is/are going to be

　　其中后两个句子中说到的情况一定是不存于当下的，在判断题(TRUE/FALSE/NOT GIVEN)中容易被揪出来做文章，出题思路是细节不一致的类型，答案多为FALSE。

　　结合讲解的部分，有时间的同学可以练习一下快速理解以下这些来自剑桥考题当中的长难句，试着找出句子的主干：
