目的状语从句和结果状语从句的区别
目的状语从句和结果状语从句都是状语从句的一种,它们的主要区别在于表达的目的不同:
1、目的状语从句:目的状语从句表示主句中的动作或状态发生的目的或目标。这种从句通常由连词 "so that", "in order that", "lest", "for the purpose of" 等引导。例如:
- He works hard so that he can pass the exam.(他努力学习以便能够通过考试。)

2、结果状语从句:结果状语从句表示主句中的动作或情况发生的结果。这种从句通常由连词 "so…that", "such…that" 引导,或者不使用连词,直接构成句子。例如:
- He was so tired that he couldn't stay awake.(他太累了,以至于不能保持清醒。)
- Such was his determination that he overcame all obstacles.(他的决心是如此坚定,以至于克服了一切困难。)
总的来说,目的状语从句强调动作或状态发生的目的,而结果状语从句强调动作或状态发生的结果。
