词语分隔现象的原因：简单地说，在英语句子中，两个结构关系密切或意义紧密相连的成分应紧挨在一起。但有时因为语法句型或修辞表达的原因，需要在这些紧密相连的成分之间插入一些其他词语，从而造成分隔现象。

1．为了让句子保持平衡、避免头重脚轻的现象，或者为了避免累赘而分隔。如：

She keeps in the garden some of the most lovable little rabbits you ever saw. 她在花园里养着一些你所见到过的最可爱的小兔。

宾语较长而状语太短，故将地点状语in the garden提到宾语前，造成动宾分隔。

2．为使表达更准确、严密，以免引起误解而分隔。如：

He has promised to really unite the people in the company. 他许诺要真正团结全公司的人。（修饰unite）

这是一个分裂不定式，really因为修饰unite，须放在之前。如果将really放在句末或其他位置，句意会发生变化。如：

He has really promised to unite the people in the company. 他确实许诺要团结全公司的人。（really修饰has promised）

He has promised to unite the people in the company really.（really可能修饰promised，也可能修饰unite，造成歧义。）

3．为了强调，可将句中某个成分置于句首或句尾，或为了使上下文衔接紧凑而把句中某个成分置于句首，或为了突出某一部分，从而造成分隔现象，如：

Happy people, as especially in individualistic Western cultures, like themselves. 快乐的人都十分赏识自我表现，这在强调个性的西方文化中显得尤为突出。

Happy people like themselves.一句本身已很短，本句中插入成分as especially in individualistic Western cultures因此显得很醒目，这样做的目的在于强调。

4．避免句式呆板，使表达生动活泼。如：

It was, as I said, not to be liked. 正如我所说的那样，这是不招人喜欢的。

as I said现置于句中造成句子分隔，说出时有所停顿，句式显得较灵活。
