   同位语从句和定语从句在形式上基本相同,都是跟在名词或代词之后,且又常由that引导。但它们的句法功能却是不同的,我们可以从三个方面来加以区别。


  (1)根据that来区别。引导定语从句的that是关系代词,除了起连接主句和从句的作用外,还代替先行词在从句中充当一个成分。而且这个that还常可以用which来代替。引导同位语从句的that是个连词,只起连接主句和从句的作用,在从句中不充当任何成分,也不能用which来代替。例如:
  The fact that(which) we talked about is very important.我们所谈论的那个事实很重要。(that在从句中作about的宾语)
  The fact that he succeeded in the experiment pleased everybody.他实验成功这个事实使我们大家很高兴。(that只起连接作用)
  再如:The news that you heard is true.你听到的消息是真的。(that在从句中作heard的宾语)
  Here comes the news that some tourists from America will come to our village.消息传来,说一些美国旅游者要来我们村。(that只起连接作用)
  (2)根据先行词来区别。
  定语从句的先行词可以是人,也可以是具体事物或抽象概念。定语从句在复合同中相当于形容词,对这些先行词起修饰、描述或限制的作用。例如:
  The moon is a satellite 1 that goes around the earth.月亮是围绕地球运转的一颗卫星。
  The few points that the president stressed 2 in his report are very important.总统在报告里强调的几点确实很重要。
  同位语所进一步说明的词则是抽象意义的概念,如:fact,result,discovery,news,hope,reason,proposal,thought等。同位语的作用相当于名词,对前面的名词给予补充说明或进一步解释。例如:
  He has an idea that he can make the scientific instrument in a better way.他想到能用更好的方法制造这种科学仪器。(从句是idea的具体内容)
  He expressed the hope that he would come to China a-gain.他表达了他要再来中国的希望。(从句是hope的具体内容)
  (3)根据引导词来区别。
  如果引导从句的词为when,where,why或者how,而其前面的名词又分别表示时间、地点、原因或方式方法等意义,则它们为关系副词,引导的是定语从句。例如:
  I’ll never forget the day when I saw the Great Wall.我永远不会忘记我见到长城的那一天。
  This is the room where Lu Xun once lived.这是鲁迅曾住过的屋子。
  而这些连接副词与前面的名词意义不相关时,这些词便是连接副词,引导同位语从句前面的名词往往也是idea,truth,news等。例如:
  The question when we will start the work is not decided 3.我们何时开始工作的问题尚未决定。
  You have no idea how worried I was.你不知道我是多么担心。

n.卫星
  • The moon is a satellite of the earth.月球是地球的一颗卫星。
  • A man-made satellite has been launched.人造卫星上天。
adj.紧张的,有压力的
  • Loud music makes me stressed out.大声的音乐让我很紧张。
  • He stressed that we should always be honest.他强调我们应该永远诚实。
adj.决定了的,坚决的;明显的,明确的
  • This gave them a decided advantage over their opponents.这使他们比对手具有明显的优势。
  • There is a decided difference between British and Chinese way of greeting.英国人和中国人打招呼的方式有很明显的区别。
