How are first conditionals formed?

This is how you formulate first conditionals in English:

If-clause (condition)Main clause (result)
If/When + simple presentwill + infinitive
If the product is successful,we will make a lot of money.
When I finish work,I will call you.

It is also possible to form first conditionals with words such as in case, unless, as long as and as soon as. Look at these examples:

I'll give you a key in case I'm not home.
I don't want to stay in Frankfurt unless I get a well-paid job.
I'll happily work on Saturday as long as I can have Monday off.
I will speak to my boss as soon as she arrives.
