独立主格最容易出错的是n, n的形式,很容易理解成2个独立句子没有连词连接。看下面的题目: Sound can travel through water for enormous distences, prevented from dissipating its acoustic energy as a result of boundaries in the ocean created by water layers of different temperatures and densities. A) prevented from dissipating its acoustic energy as a result of B) prevented from having its acoustic energy dissipated by C) its acousitic energy prevented from dissipating by D) its acousitic energy prevented from being dissipated as a result of E) preventing its acoustic energy from dissipating by
答案是C its acousitic energy prevented from dissipating by 做独立主格结构 从语法角度来看E没有错,但是逻辑意思不吻合, oceran 阻住acousitic energy 扩散,而不是sound本身阻止其扩散。有时,误以为独立主格是完整句子很容易吧C,D先排除。在加上时间紧,直接选了E,动词ing做伴随状语。其实不然。独立主格结构概念如下:
“独立主格结构”实质就是带有自己主语的非限制性状语从句。众所周知非限制性从句通常以主句的某一成分作为自己的逻辑主语,从而依附于主句。而有些非限制性从句和无动词从句带有自己的主语,在结构上与主句不发生关系,因此成为独立主格结构。其实,虽然叫做独立主格结构,并不是真正的独立,它还是一种从属分句,在句中有多种作用。如:表原因、表条件、表方式、表伴随、表时间等,在句中通常起状语作用。
但如果C改成 C) its acousitic energy is prevented from dissipating by,那就不能选了,明显的一个句子有两个完整的主谓结构。
请NN检验~~~ |
