摘要:1. 不定式作目的状语的基本形式结构:to + 动词原形功能:直接说明主语动作的目的,相当于中文的“为了……”。He woke up early to catch the train.(他早起是为了赶火车。)→ "to catch the train" 解释了 "woke up early" 的目的。2. 强调目的:in order to / so as to为了更明确地强调目的,可以用 in o

1. 不定式作目的状语的基本形式

结构:to + 动词原形
功能:直接说明主语动作的目的,相当于中文的“为了……”。

  • He woke up early to catch the train.
    (他早起是为了赶火车。)
    → "to catch the train" 解释了 "woke up early" 的目的。

2. 强调目的:in order to / so as to

为了更明确地强调目的,可以用 in order toso as to(更正式或书面化)。

  • She studies hard in order to pass the exam.
    (她努力学习是为了通过考试。)
  • He saved money so as to buy a new car.
    (他存钱是为了买一辆新车。)

注意事项:

  1. so as to 一般不用于句首,而 in order to 可以:(有一篇专门讲so as to )
  • In order to improve English, she practices daily.
  • ❌ ~~So as to improve English...~~ (不自然)

2. 否定形式

  • in order not toso as not to 表明“为了避免……”。
  • Example:
  • She left quietly so as not to wake the baby.
    (她悄悄离开,以免吵醒宝宝。)

3. 与“缘由”和“结果”状语的区别

不定式作状语时,需根据上下文判断是表目的、缘由还是结果:

类型

标志词/结构

例句

逻辑关系

目的

to / in order to / so as to

He exercises daily to stay healthy.

动作的意图(主动为之)。

缘由

形容词 + to do

I’m sorry to hear the news.

因某事而产生情绪(被动反应)。

结果

too...to / enough to

The tea is too hot to drink.

自然导致的结果(非主观意图)。

例句对比:

  • 目的:She bought a map to find the way.(她买了地图是为了找路。)
  • 缘由:She was surprised to see him.(见到他,她很惊讶。)
  • 结果:The box is too heavy to lift.(箱子重得抬不动。)

4. 不定式目的状语的替换表达

如果想避免重复使用不定式,可以用以下方式替换:

  1. 用“for + 名词”表明用途
  • He woke up early for the train ride. (为了乘火车)
    (他为火车早起。→ 强调“为了赶火车”这件事。)
  • He woke up early to catch the train. (更清晰)

2. 用“so that + 从句”(更强调目的和结果):

  • He woke up early so that he could catch the train.
    (他早起是为了能赶上火车。)

5. 常见错误纠正

  • 错误:~~He came to the party for to meet friends.~~
    • ✅ 正确:He came to the party to meet friends.
      ("for" 不能直接接不定式,需用 "to" 或 "in order to"。)
  • 错误:~~She studies hard for not failing the exam.~~
    • ✅ 正确:She studies hard in order not to fail the exam.

6. 练习与巩固

尝试将以下句子改为不定式目的状语:

  1. She turned off the phone. She didn’t want to be disturbed.
    She turned off the phone so as not to be disturbed.
  2. They brought tools. They planned to repair the fence.
    They brought tools to repair the fence.
