4. Mrs. Sterling got so angry that she ran after them.
☆so…that，such…that：so后面是跟形容词和副词；而such后面是跟名词。
such…that…与so…that…都可以用来引导结果状语从句，意为“如此……以致……”。
such…that…的句型结构可分为以下三种：
①such +a（n）（+adj.）+单数可数名词+that从句。

Table tennis is such an interesting game that people all over the world play it.
②such（+adj.）+复数可数名词+that从句。如：

注意
①当名词前面有many，much，few，little等表示数量多少的限定词时，应该用so，而不能用such。

②当单数名词前有形容词时，既可用so，也可用such，但不定冠词的位置却有所不同。

☆need/want doing sth. 需要被做，后面接的动名词有被动的含义。=need to be done

☆mend是表示“修修补补，小修小补”，常用于修补打破、撕破的东西或衣物等。repair也是表示“修理”，不过repair是指修理好损坏的、用旧的东西，或是出故障的机器

2、动名词还可以用于“动词+介词”之后
①to后跟动名词的有（此时to为介词）

be accustomed to doing sth. 习惯于做某事

②其他介词

3、在start，begin，continue等后面，既可以用不定式又可以用动名词，区别不大：
I began to learn/learning English two years ago.
③与表示心理状态的词连用：begin to realize/understand. She began to understand. 她渐渐地明白了。
但在有些情况，通常用to do.如：
①进行时态中：be beginning to do.
The water is beginning to boil.
水开始沸腾起来了。
②物作主语：sth begins/began to do sth.
It begins to rain.
4、在hate、love，like，prefer等动词后，用不定式和动名词意义有所区别。
hate,love,like+doing sth. 表示一种习惯(always)
hate,love,like+to do sth. 表示某一次行为(now)
would love /like to do sth. 表示想要
类似的词还有remember to do ／doing
forget to do ／doing
regret to do ／doing
stop to do ／doing
try to do ／doing
mean to do ／doing
5、在need，want之后，动名词形式具有被动的含义，相当于被动的不定式.
如果以物体做主语，可以直接加动词-ing，表达被动的含义
My shirt is torn. It needs mending. 我的衬衫撕破了, 需要缝补.
Those windows are dirty. They want washing. 那些窗户很脏, 需要洗刷
【Special Difficulties】
catch and run
catch主要意思是“抓住、捉住、逮住”，但有时可以表示“（及时）赶上、追上”等：
He ran quickly to catch the last bus home.
When she caught up with them, she saw that they were going through the contents of the bag.
run的本意是“跑”，后面加上不同的小品词可以表达“追赶，逃跑”等多种含义：
She has run off with all his money.
The man ran away with her bag.
run after
