结果状语从句 so that引导目状语和结果状语的区别

如题所述

  so that引导目状语和结果状语的区别
  
  (1)含义上的区别:引导目的状语从句时表示的是一种意欲或可能性,引导结果从句时表示的是一种事实。
  
  (2) 形式上的区别:引导目的从句之前不用逗号(说话时也不停顿),而结果从句之前则通常有逗号(说话时常有停顿);有时引导结果状语从句时其前也可以没有逗号,此时可看从句中是否有 can / could, may / might, will /would 以及should等情态动词,如果没有,则多半是结果从句。比较:
  
  We’ve come early so that the meeting can begin promptly. 我们来得很早,以便可以马上开会。(so that 引导目的状语从句)
  
  We are all here now, so that the meeting can begin at last. 我们现在都到齐了,终于能开会了。 (so that 引导结果状语从句)
  
  I am going to the lecture early so that I’ll get a good seat. 我想早点去听演讲,以便找个好座位。(so that 引导目的状语从句)
  
  I went to the lecture early so that I got a good seat. 我去听演讲去得很早,所以找个好座位。(so that 引导结果状语从句)
  
  另外,so that引导目的从句时有时可放在主句之前,而引导结果从句时却不能:
  
  正:So that he could buy a new car, he saved a lot of money. 他节省了一大笔钱,以便能买辆新车。(引导目的状语从句)
  
  误:So that I could hardly stand, I was tired.(引导结果状语从句不能置于句首,可改为I was tired so that I could hardly stand. 我很累,几乎站不稳了。)
