托福阅读长难句一直是困扰不少同学的一大难关。让想要看懂文章大家就必须先学会看懂长难句。下面小编就来为大家介绍阅读长难句中较为常见的倒装类句式，从句子形式和目的两个方面为大家做具体讲解。

托福阅读长难句式倒装句的目的

想要看懂倒装句，首先大家要了解一下句子倒装的目的是什么，一般来说，使用倒装句主要有以下两个目的：

一是被提前的部分被强调，如下面的第五句：Accustomed though we are to speaking of the films made before 1927 as “silent”，其中的accustomed按照正常语序应该放在are之后：Though we are accustomed to speaking of the films made before 1927 as “silent”。之所以将accustomed提前，是为了强调它。

二是为了句子的平衡，否则将导致头重脚轻的效果，如下面的第一句、第二句和第四句。以第一句为例，按照正常语序应该是：Fossils clearly intermediate， or transitional， between land mammals and cetaceans were missing until recently。但是这种句子结构比较糟糕，因为主语及其修饰语过长(从句首直到cetaceans)，而谓语部分were missing until recently较短，容易造成头重脚轻的效果。第一句将missing提前，避免了这一现象。
