非限定性定语从句功能用途

如题所述

限定性定语从句与主句之间的关系紧密,它们起着限定和修饰先行词的作用,若去掉则可能影响句子的完整性和理解,甚至产生混淆。例如:


热带雨林因作为有价值的木材和资源,被砍伐以促进它们所在地国家的经济增长:
Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nations in which they are located.


洋流影响流经地区气候:
Ocean currents affect the climates of the lands near which they flow.


他们解释之前讨厌我们的原因:
They explained the reason to us why they had hated us before.


相反,非限定性定语从句与主句关系松散,它以逗号隔开,不限定或修饰先行词,而是提供补充或说明。即使删除,句子意思依然完整。非限定性定语从句在中文中通常被当作独立部分处理。例如:


巴比伦人曾尝试绘制世界地图,但他们的地图是扁平的,而非球体,这与托勒密采用的形式不同:
Earlier, the Babylonians had attempted to map the world, but they presented it in the form of a flattened disc rather than a sphere, which was the form adopted by Ptolemy.


卫星、存储信息的计算机和显示信息的电视的结合,将每个家庭转变为教育和娱乐中心:
The combination of satellites, which transmit information, computers, which store information, and television, which displays information, will change every home into an education and entertainment center.


太阳给予大地热量,使植物生长成为可能:
The sun heats the earth, which makes it possible for plants to grow.


那位老人有一个在部队工作的儿子:
The old man has a son, who is in the army.


在这些例子中,非限定性定语从句用来补充说明,而不是限定先行词的范围或特性。


扩展资料

非限定性定语从句起补充说明作用,缺少也不会影响全句的理解,在非限定性定语从句的前面往往有逗号隔开,如若将非限定性定语从句放在句子中间,起前后都需要用逗号隔开。
