Grammar B
unless意为“除非，如果不”，可用来引导条件状语从句。unless引导的从句既可以放在主句之前也可以放在主句之后。当从句位于主句之前时，常用逗号与主句隔开。
e.g. He won’t come to the party unless you invite him.
如果主句是一般将来时态，则unless 引导的从句的时态通常用一般现在时表将来。Sometimes we can use if ... not to replace unless.
e.g. The situation will continue unless humans stop hunting them for their fur and bones.
= The situation will continue if humans do not stop hunting them for their fur and bones.
The unless-clause can come first or after the main clause.
e.g. Unless you try your best, you will not realize your dream.
You will be late unless you leave right now.
在unless引导的条件状语从句中，主句也可以含有情态动词或祈使句。
e.g. He cannot see clearly unless he wears glasses.
Don’t touch the machine unless the teacher allows you to.
1. Unless the weather report
says it is going to rain,
2. We will arrive at the
studio around 9:30 a.m.,
3. Unless you already know
the studio very well,
4. You will buy your lunch at
the restaurants in the
studio,
5. Unless you are tired,

an umbrella with you.
unless the traffic is very
heavy.

interest in it.
