We can use unless to say that something
can only happen or be true in a
particular situation.
e.g. He won’t come to the party if
you don’t invite him.
=He won’t come to the party unless
you invite him.So we can useunless to replace if ... not .

humans do not stop hunting them
for their fur and bones.
→ The situation will continue unless
humans stop hunting them for
their fur and bones.
2. If it does not rain tomorrow, we are
going to play football in the park.
→ Unless it rains tomorrow, we are
going to play football in the park.
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.

条件状语从句主要由if或unless引导:?
if条件句?
?1) if条件句:条件句用于陈述语气,表示
假设的情况可能发生,其中?if?是“如果”
的意思。
e.g. If it rains, we will stay at home.
如果下雨我们就待在家里。Grammar2)?用法:?
(1)条件状语从句通常由连词if引导,意为“如
果、假如”,主句不能用be?going?to表示将
来,而应该用shall, will。
e.g. If?you?leave?now,?you?will?never?regret?it.?
如果你现在离开,你永远都不会后悔。
(2)if?“如果”,引导条件状语从句,主句用一般将来时,从句则用一般现在时。
e.g. If?it?rains?tomorrow,?I?shan’t?climb?the?hills.
如果明天下雨,我就不爬山了。(3)主句是祈使句或含有情态动词,从句也用一
般现在时。
e.g. Please?call?me?if?he?comes?next?Sunday.
如果他下周日过来请打电话给我。
注意:?宾语从句中的if与条件状语从句if的区 别。宾语从句中的if “是否”相当于?whether, 引导宾语从句, 时态需根据语境确定。如果主句用一般现在时, 从句可以根据具体情况选用时态, 如果主句用一般过去时, 从句必须用过去时的某种形式。unless 条件句
unless引导的条件句,表示强烈的否定。翻译为“除非……”“非……不可”。
e.g. You?will?fail?unless?you?work?harder.?
你不努力就会失败的。
=You will fail if you do not work harder.
注意: unless?从句里的谓语只能是肯定
式, 因为本身unless表示否定。Finish the exercises in the
