语法结构	意义及用法
so … that	如此……以至于；引导结果状语从句 so后接__________________，强调程度，that引导的从句表示结果。
unless	除非；引导条件状语从句 相当于___________，意“除了……之外”，表示唯一条件。
as soon as	一……就；引导时间状语从句，表示两个动作在时间上紧密相连，几乎同时发生 as soon as引导的从句表示将来意义时，需用________________。

2. 用法：

①“so... that”意为“如此……以至于”，引导结果状语从句。

1）so+形容词/副词+that 从句

He was so ____________ that he couldn’t say a word. 他如此生气，以至于说不出话来。

2）so+形容词+a/an+可数名词单数+that 从句=such a/an+形容词+可数名词单数+that从句

翻译：这是一本如此有趣的书，以至于我爱不释手。

It’s ____ interesting a book _____ I can’t put it down.=It’s________ interesting book ___ I can’t put it down.

3）so many/few/much/little+名词+that 从句

There is ___________ work to do ______ everyone is under pressure.

有太多工作要做，以至于每个人都有压力。

注意：在“so... that”结构中，当that 引导的结果状语从句是肯定句且主、从句的主语是同一人或物时，可以与“be... enough to do”相互转换

 He is so ________ that he can __________ the maths problem quickly.

=He is ___________________ work out the maths problem quickly.

他如此聪明，以至于能很快算出那道数学题。

当that引导的结果状语从句是否定句时，可与“too... to”或“be not... enough to do”相互转换

He was ______ short___________ he couldn’t reach the bookcase.

=He was ________ short ______ reach the bookcase.

=He was _____ tall enough _____________ the bookcase.

他太矮了，以至于够不到书架。

②unless 是连词，意为“除非；如果不”，引导条件状语从句，相当于“if... not”。用法如下：

主句：一般将来时/祈使句/含有情态动词的句子   从句：一般现在时（表将来）

Her dream _______________ unless she _______ it up halfway.除非她半途而废，否则她的梦想就会实现。
