插入语（1）

插入语是指插入到主、谓、宾、宾补（通常被称为句子的必要成分）之间的从句、短语或单词。插入语在分隔这些语法成分的同时，对句子的内容进行补充、添加、限制或解释说明。插入语按构成来划分，主要有以下几种：

1）名词结构作插入语。例如：When all these shaping forces schools, open attitudes, the premiumsystem, a genius for spatial thinking—interacted with one another on the rich U.S. Mainland, theyproduced that American characteristic emulation. 当所有这些构成因素——学校、开放态度、奖金制度、真正的空间思维方式——在美国本土相互作用时，具有美国特点的竞争就被孕育出来了。

2）形容词或副词结构作插入语。例如：Because thanks to these schools, our early mechanics, especially inthe New England and Middle Atlantic states, were generally literate and at homein arithmetic and in some aspects of geometry and trigonometry. 因为有这样的学校，我们当年的技工——特别是新英格兰和大西洋沿岸中部各州的技工——总体上来说是有文化、懂算术并具有一定的几何三角知识的。

3）介词短语作插入语。例如：It should be observed , of course, that no school, vocational or not,is helped by a confusion over its purpose. 当然应该注意到，不管是职业学校还是非职业学校，目标混乱都是有益无害的

4）连词作插入语。例如：On the other hand, though , if a child is left alone too much, orwithout any learning opportunities, he loses his natural enthusiasm for lifeand his desire to find out new things for himself. 但是另一方面，如果放任一个孩子过度自由，或是不给他任何学习的机会，他就会丧失对生活天生的热情，失去发掘新事物的欲望。
