独立主格（absolute phrases）这个语法点在托福雅思阅读中并不少见。独立主格部分的主语与主句的主语不一致，独立主格的一种形式是以【名词、名词短语、或者代词 + 非谓语】的形式呈现，非谓语可以是现在分词、过去分词、形容词、介词短语或者是名词。另一种形式则是在名词部分和非谓语之前再加 with，也就是【with + 名词、名词短语、或者代词 + 非谓语】。

遇到独立主格，可以在两句话之间加上连词（往往是 and），将独立主格的非谓语变成谓语形式，这样处理，句子看上去更加顺眼。

下面我们看一个来自托福阅读机经（The Domination of the Earth by the Dinosaurs）的句子：

For 30 million years, dinosaurs and crurotarsans lived side by side with neither dominating the planet.

这句话独立主格的形式是【with + 代词 + 现在分词】。意为三千万年中，恐龙和一种叫 C 的动物共存，谁都没能统治地球。这句话改成并列句是：

For 30 million years, dinosaurs and crurotarsans lived side by side, and neither dominated the planet.

在今年 3 月 18 号雅思阅读考试第一篇关于研究壁虎爬行原理的仿生学文章（Designs from Nature）中，有这样一句话：

In reality, gecko feet aren’t sticky—they’re dry and smooth to the touch—and owe their remarkable adhesion to some two billion spatula-tipped filaments per square centimeter on their toe pads, each filament only a hundred nanometers thick.

这句话末尾独立主格的形式是【名词 +（数字 + 单位 + 形容词）】。意为事实上，壁虎的脚没有粘性，干燥且平滑，它们有吸附能力是因为脚掌上（toe pad）的 filaments，每一份 filament 只有一百纳米那么厚。这句话改成并列句是：

In reality, gecko feet aren’t sticky—they’re dry and smooth to the touch—and owe their remarkable adhesion to some two billion spatula-tipped filaments per square centimeter on their toe pads, and each filament was only a hundred nanometers thick.

在剑桥雅思四的第一篇文章（C4T1P1）中，便出现了独立主格：

Perhaps encouragingly, more than half of the pupils (59%) identified that it is human activities which are destroying rainforest, some personalizing the responsibility by the use of terms such as ‘we are’.

这句话末尾独立主格的形式是【代词 + 现在分词】。意为让人感到鼓舞的是，超过一半学生认为人类活动破坏了雨林，有些学生用“我们”这个词来把责任归于人。这句话改成并列句是：

Perhaps encouragingly, more than half of the pupils (59%) identified that it is human activities which are destroying rainforest, and some (pupils) personalized the responsibility by the use of terms such as ‘we are’.
