对于各位雅思考生来讲，雅思作文是雅思考试的很大一部分，但是长难句特别是使用从句却成了很多人取得雅思写作高分的克星，从句在雅思作文中可以表达更多的信息，一直都是雅思写作高分的黄金句式，但是从句不好写，因为大家一不小心就容易把从句写的很俗，或者采用中式的表达写从句，究竟在从句写作方面有没有很好的提高方法呢?下面澳际小编和大家一起探讨一下这个话题。

　　定语从句

　　纵观剑4至剑10的所有考官范文，定语从句乃是当之无愧高频句，现摘取如下较典型的例句与读者共同探讨：This has been driven by technological and scientific breakthroughs that are changing the whole way we view the world on an almost daily basis.句中，that 引导的定语从句：that are changing the whole way we view the world on an almost daily basis. 是对先行词technological and scientific breakthroughs 的限定说明，它不影响主句：This has been driven by technological and scientific breakthroughs. 的语法结构。因此，我们的出结论：定语从句的功能是对句中某个名词作限定说明，使用方法就是在名词后+that/which(先行词为事物)或who(先行词为人)并且把这些引导词当成主语，接着补充成一个句子就行啦。

　　状语从句

　　再看看同样使用频率较高的状语从句：For example, if sufficient sky trains and underground train systems were built and fectively maintained in our major cities, then traffic on the roads would be dramatically reduced.句中，if 引导的是条件状语从句：if sufficient sky trains and underground train systems were built and fectively maintained in our major cities. 主句一般而言表示基于此条件的结果。我们试着来总结一下它的使用公式：if+句子(条件)+ then+句子(结果)。需要注意的是由于是虚拟条件，if 引导的条件从句用一般过去时，主句用虚拟语气较为常见。(具体请参照例句理解)

　　宾语、表语从句

　　宾语从句、表语从句也很常见：They may think that it is better to continue in a particular job, or to do something completely different from a university course.句中，that 引导的从句：that it is better to continue in a particular job, or to do something completely different from a university course. 作think 的宾语。That 本身在从句中不做任何成分。我们来探讨宾语从句的使用规律：主语+谓语+that+完整句子。就构成了一个宾语从句。按此规律，我们来看看表语从句：The obvious argument in its favour is that young children pick up languages much more easily than teenagers.句中，that 引导的表语从句：that young children pick up languages much more easily than teenagers. 作系动词 is 的表语。使用方法不再赘述。

　　最后，同位语从句

　　笔者给大家看看同位语从句：Obviously, education systems are based on the beli that all children can fectively be taught to acquire different skills, including those associated with sport, art or music.句中，that引导的同位语从句：that all children can fectively be taught to acquire different skills, including those associated with sport, art or music. 是对先行词beli的补充说明。其用法为：在句中需要补充说明的名词后+that +句子。注意，同位语从句的引导词一般是that，并且不在从句中作成分，定语从句则有多个引导词，且一般在从句中做成分。

　　以上三种句式是雅思写作中常用的句式，在提高雅思写作考试中发挥着非常重要的作用，大家在平时的雅思写作练习中可以着重练习这三种中句式，然后再配合背诵雅思作文范文，我往往会发另大家意想不到的效果。
