unless的用法
unless是从属连词，意思是“除非……如果不……”，“除了……”，引导含有否定意义的真实条件状语从句，相当于if条件状语从句的否定形式。 unless引导的条件状语从句和if条件状语从句都用一般现在时代替将来时
如：You will miss the bus unless you hurry up.
你将会错过班车除非你快一点。
You won’tl pass the test unless you work hard.
如果你不努力学习你不会通过考试的。
unless和if……not都可以引导否定意义的条件状语从句，所以它们有时可以互换。
[比较] so...that...与so that
So that:
(1) 引导结果状语从句，意为“因此，所以”，主句和从句间常用逗号分开，一般不与情态动词连用。
Nothing more was heard of him, so that people thought thathe was dead.
未再听到他的消息，以致人们认为他已死去了。
(2) 引导目的状语从句，意为“为了，以便”，通常从句中用may，might，can，could等情态动词。We left early so that we could catch the first bus.我们很早出发，以便能赶上第一班汽车。
注意: so that引导目的状语从句时，可用in order that(以便为了) 替换，以上两句中的s that均可换成in order that。

as soon as 意为“一……就……”，引导时间状语从句。
表示从句的动作一发生，主句的动作马上发生，强调动作的紧密性。
as soon as
指紧接着发生的两个短动作：
A现在时as soon as B现在时
A过去时as soon as B过去时
I went to do my homework as soon as I came back home.
A将来时as soon as B将来时(可用一般现在时表将来)
They will send me the books as soon as they receive my money.
指未发生的动作
as soon as连接的时间状语从句中，指未发生的动作，规律是：主句一般将来时，从句用一般现在时代替一般将来时。 如：
I will tell him the news as soon as he comes back。
指紧接着发生的两个短动作，主、从句都用一般过去时。
He took out his English books as soon as he sat down.
Using as soon as
unless意思是“如果不，除非”，相当于if ... not ...。if ... not ... 是口语，unless是书面语。unless引导的从句放在主句之前时，要用逗号和主句隔开。如:
Using unless
You will miss the bus unless you hurry up.
你要不快点就会错过班车。
注意：
在含有unless和as soon as引导的状语从句中，如果主句用一般将来时或主句的谓语部分含有情态动词，那么unless和as soon as引导的从句常用一般现在时。
Language points
1. as soon as.....·就。....
as soon as 引导时间状语从句,用一般现在时态表示将来。主将从现
类似的还有由when,until,as 等引导的时间状语从句和由i f引导的条件状语从句。如:
'll call you as soon as I get there.
What are you going to be when you grow up
He won't go to bed until his mother comes back.
We'll go to the park if it doesn't rain tomorrow.
“so…that…”意为 “如此/这么……以至于……”，常引导结果状语从句。
so ... that
so是副词，常常与形容词或副词连用，常用句型为：
主语 + 谓语 + so + adj. /adv. + that从句
The boy ran so fast that I couldn’t catch him.
He was so angry that he couldn’t say a word.
so ... that表示“如此……以至于……”，
常见结构为“so +形容词/副词+ that从句”或“so +形容词+ a / an +单数名词+ that从句”。如:
He was so excited that he couldn’t say a word.
It is so interesting a book that many people want to buy it.
Using so ... that
I got up early so that I could catch the early bus.
Please open the window so that we can breathe fresh air.
You must go now so that you won’t be late.
注意：so 与 that也可连起来写，即：
… so that … (以便/为了……)，引导目的状语从句

Practice
Fill in the blanks with unless, as soon as or so… that.
点拨：分析句子结构可知，后一句“继姐让她做所有的家务”是主句，上一句“她的父亲死后”应是句子的时间状语。因此，应用as soon as来引导时间状语从句。 as soon as 意为“一……就”，时态遵循“主将从现；主过从过”的原则。
1. ___________ her father died, the
stepsisters made her do all the chores.
As soon as
点拨：分析句意可知“忙”所导致的结果是“没有时间为聚会做一件礼服”。
so… that… 意为“如此……以至于”，常用于结果状语从句，表示上文动作所产生的结果，故空格处应用so…that。前后句时态，要保持一致。
2. She was ____ busy _____ she had no time
to make a dress for the party.
so that
