插入语是长难句中常见的“干扰成分”，它的出现往往“不按常理出牌”，打乱原有的句子结构，带来阅读障碍。插入语对句子理解造成的困难在于，大段插入语出现在句子中间，容易打断读者的思路，常常刚读完插入部分，就完全忘了前面的句子，后面的句子成分更不知所云了：或者，将插入语和句子前后部分内容混淆，对句意的理解出现偏差，给理解文章带来很大不便。所以插入语的难点就在于对它的精准识别。

　　一、插入语的判定

顾名思义，插入语就是在一个完整的句子中插入一个“本不该有”的成分。它存在的意义是使句子结构灵活化，不那么单调。插入语的判定方法很简单：找出句子主干(主谓宾)，发现在语法上不从属于任何一部分的、“多余的”成分，就是插入语。

插入语间隔的位置有如下几类：

1) 主谓分隔：

This view, however, seems to be wrong.

Rose, a young American poet, is brilliant.

Susan, I suppose, finds the right way to go.

2) 复合谓语分隔：

You might at least offer to help.

Mr. McWhorter’s academic specialty is language history and change, he sees the gradual disappear of “whom”, for example, to be natural.

3) 动宾分隔：

They estimated in the newspaper the costs of health care.

4) 固定搭配分隔：

They thought in a systematic way about the problems.

5) 连词与后续部分分隔(最为复杂)

What is hard to establish is whether the productivity revolution that the business assume they are presiding over is for real.

二、插入语的处理

为方便起见，按识别标志把插入语分两类：

(1)标点分隔型插入语:直接跳读，节省阅读时间

总而言之，我认为我们可以说我们做得很好。

句子电脑具有潜力的迹象，就像我们看到的弦理论的解释能力一样，将为（人们）获取它完整的能力提供强烈动力。

注：rather than作为特殊的万能插入语，表示“肯前否后”，可以放在句子中的任何一个成分后面。

It abolishes the presumption of innocence and places the citizen at the service of the state rather than the other way round.

新法废除了公民的无罪假定并且将公民置于为政府服务的地位，而非政府为公民服务。

【实战练习】18303 -OG21新题

As opposed to adults, pound for pound, children breathe twice as much air, drink two and a half times as much water, eat three to four times as much food, and have more skin surface area.

A. As opposed to adults, pound for pound, children

B. Compared pound for pound with adults, children

C. Unlike an adult, pound for pound, children

D. Pound for pound, a child, unlike an adult, will

E. Pound for pound, children compared to adults will

【分析】正确答案B

A选项，pound for pound，修饰歧义，可以修饰adults，也可以修饰children；成年人不是不喝水，所以不能用相反的比较，排除CD；E选项，compared做后置定语修饰children，被与成人相比的孩子要呼吸两倍的空气……,逻辑不通顺；D/E选项问题是一样的，题目陈述的是客观事实，即成人与儿童呼吸、饮水等行为，应该用一般现在时，而不是将来时；B表达更准确。

句意：与成年人相比，同样体重的孩子呼吸的空气是成年人的两倍，喝的水是成年人的2.5倍，吃的食物是成年人的三到四倍，皮肤表面积也更大。

这些都是在日常学习中较为常见的，对于插入语不仅"知其然"，而且"知其所以然"，一定可以让我们对它的理解更为深刻，在运用的过程中更加"游刃有余"!
