逗号前后是我们写作时构造复杂多变、精彩生动句子结构的突破口。上述三例中我们合理巧妙地运用了非限制性定语从句，使前后两个分句有机地连接起来，显得连贯、自然。例1用关系代词which (非限制性定语从句不能用that)代替逗号前整个分句的意思。这样就把原本要用两个句子来表达的信息通过定语从句压缩为一个主从复合句，显得简洁、不罗嗉。例2用关系代词which代替逗号前先行词the green house，通过非限制性定语从句进一步说明温室对于鲜花存活的重要性。例3中逗号前先行词是表时间，因此用关系代词when引导非限制性定语从句，将主要信息移置逗号之后，取得“尾重”或“末尾聚焦(end—weight)”的效果。其实考生们对于非限制性定语从句的用法不可谓不熟，但可能就是缺乏用多种手段衔接分句的意识。

同位语或插入语一般插在主谓语之间，一般由名词词组(如例l、2)、介词词组(如in my opinion，in other words等)、从句(如例3)、不定式短语、现在分词短语充当。它们能起到补充说明的作用。除此之外，插入语还可对整句话表示解释，如：
4.There were twenty people present，to be precise.(不定式短语做插入语)
5. Roughly speaking，these countries are the most densely—populated in Asia.(现在分词短语做插入语)
