If-clause
(simple present tense)
Main clause
(will/may/might/…+infinitive)
If you are a football fan,
you will not want to miss this week’s programme.
If you are an animal-lover,
you may feel sad about it.
Pay attention:
We put a comma after the if-clause when it is the first part of a sentence.

Section B
1. Tell the students : 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 unless you invite him.
2. Explain: 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.
