自我探究
1．to do表示目的，引导目的状语从句。
2．in order to do表示目的，引导目的状语从句。
3．so as to do表示目的，引导目的状语从句。
一、动词不定式作目的状语
讲解归纳
用法 例句
不定式作目的状语的常用结构：to do，only to(仅仅为了)，in order to，so as to，so/such...as to(如此……以便……) I got up early to catch the early bus.我早起是为了赶早班公共汽车。He ran so fast as to catch the first bus.他跑得飞快以便赶上第一班公共汽车。
用法 例句
不定式的否定形式是不定式符号to的前面加not。 She studied very hard in order not to lag behind.她学习很努力以便不落在别人的后面。
in order to引导目的状语，可以置于句首，也可以置于句中；但so as to引导目的状语，只能置于句中，而不能置于句首。 They started early in order to get there in time.他们出发得早是为了及时到达那里。In order to get there in time，they started early.为了及时到达那里，他们出发得早。
They started early so as to get there in time.他们出发得早以便及时到达那里。
用法 例句
下列情况中，不定式有其自己的逻辑主语：
(1)在for sb. to do结构中；
(2)在bring，send等动词的宾语后；(3)在to be done结构中。 He opened the door for the children to come in.他打开门让孩子们进来。They sent a man to mend the window.他们派了一个人去修理窗子。
He wants the file to be typed up right now.他想让文件立刻被打印出来。
用法 例句
only to可有两层含义：表示目的，意为“只是因为……”；表示出人意料的结果。 I come here only to say goodbye to you.我来这里，仅仅是为了向你道别。We hurried to the classroom only to find none there.我们匆忙赶到教室，却发现那里没有一个人。
二、结果状语从句
用法 例句
结果状语从句常由so that，so...that...，such... that...等引导。so...that...和such...that...中的that有时(尤其在口语中)可省略。 He studied hard so that he passed the exam.
他努力学习，所以他通过了考试。
He was so angry (that)he couldn’t speak.
他气得话都说不出来了。
He shut the window with such force (that) the glass broke.
他关窗户用力太大，玻璃都破了。
用法 例句
so...that...的用法：(1)so＋adj./adv.＋that从句；
(2)so＋many/much/few/little＋名词＋that从句；
(3)so＋adj.＋a/an＋单数可数名词＋that从句；
(4)“so＋被修饰成分”置于句首，主句要倒装 I am so busy that I have no time to write a letter.
我很忙，连写信的时间都没有。
There were so many people there that I wasn’t able to pick her out.
那儿有很多人，我没能找到她。
They are such little children that they cannot understand what you say sometimes.
这些孩子很小，有时他们不理解你所说的。

他是一个优秀的学生，我们都想以他为我们的好榜样。
So badly was he injured that he had to be sent to the hospital.
他伤得很重，不得不被送往医院。
用法 例句
such...that...的用法：
(1)such＋a/an＋adj.＋单数可数名词＋that从句；
(2)such＋adj.＋不可数名词＋that从句；
(3)such＋adj.＋可数名词复数＋that从句；
(4)“such＋被修饰成分”置于句首，主句要倒装。 The French man caught such a bad cold that he coughed day and night. 这个法国人得了重感冒，以至于他整日咳嗽。
He made such rapid progress that before long he began to write articles in English.

那些电影非常有趣，我们想再看一遍。
Such a lovely girl is she that all her classmates like her.
她是一个很可爱的女孩儿，她所有的同学都喜欢她。
用法
例句
so...that...和such...that...有时可以互换，条件是中心词必须是单数可数名词。 It was such a beautiful evening that I could never forget it.(＝It was so beautiful an evening that I could never forget it.)那是一个如此美丽的夜晚，以至于我永远不能忘怀。

4.All these gifts must be mailed immediately___in time for Christmas.
A．in order to have received
