so...that... 如此……以致……。 that 引导结果状语从句。另外， such...that...也引导结果状语从句。其结构形式为：

so＋adj./adv.

＋adj.＋a/an＋可数名词单数

＋many/few＋可数名词复数

much/little＋不可数名词that 从句

such＋a/an＋adj.＋可数名词单数

＋adj.＋可数名词复数

＋adj.＋不可数名词that 从句

①She was so excited that she couldn't go to sleep.

(＝It was such a hot day that nobody wanted to do anything.)天气如此热，谁也不想干活。

③I made so many mistakes in the composition that the teacher criticized me.

我的作文中出了许多错误，老师批评了我。

拓展：(1)当 so.../such...位于句首时，句子要部分倒装。

So small was the mark that I could hardly see it.

那个标记非常小，我几乎看不见它。

(2)so...that...中的主句和从句的主语是同一个，that 从句也可改为 as to do 形式。

＝The old lady was so kind as to lead me to the hospital.

这个老太太是那样好心，她把我领到了医院。

(3)so that 连在一起用，可引导结果状语从句，也可引导目的状语从句。so that引导目的状语从句时，从句中常使用 can/could/may/might/will/would/should 等情态动词；引导结果状语从句时，从句中一般不用 can和 may等

词，在 so that前可以有逗号，意思是“因此；所以”。

He hurried up so that he could catch the train.

他匆匆赶路为的是赶上火车。(对比：He hurried up so that he caught the train. 他匆匆赶路，结果赶上了火车。)

(2)of＋n.结构中的名词表种类、数量、度量等时，表示不同的人或物的共同特征，此时名词前通常有冠词。常用的名词有：size, type, kind, price, height, depth, length, weight, age, shape, colour 等。

The two are of an age, but are of different height.

这两个人年龄相同，但身高不同。

(3)of＋n.结构还可以表示主语的根源关系，此时的名词多是表示亲属、血统、种族、国籍以及出处的名词，常用的名词有：family, blood, race, origin 等。

We are of the same blood. 我们是同一血统。

(4)of＋n.结构还可以表示人的特点、特性，常用 of＋wealth/education/courage/achievement/ability 等。
