英语的句式结构其实很简单：主谓宾和主系表。主谓宾是“谁—干—什么”，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，只不过修饰成分多了些、显得唐僧了些而已。主系表是“谁—是—什么”，复杂版本参考同上。要很快地理解这样的句子，我们就要学会迅速地抓出句子的主干—也就是“羊吃草”的部分，至于其它的修饰部分可以先不过大脑。如果主干显示本句子中包含了解题信息的话，此时再去细细查看题目要问的细节信息也不迟。这样的抓主干技巧一旦熟练，要有充分的时间通读三篇文章、保证不遗漏任何信息地做题，也不是什么不可完成的任务了。特别是对于那些原本语言功底就不错、希望能以阅读这一项的得分再提高一下总成绩的同学来说，这是真正的终极技巧，要达到保8望9也是很有希望的哦：） 针对两种句式结构的抓主干方法，简单说来如下：
化繁为简看懂句子
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。
