THE FIRST CONDITIONAL

In the First Conditional, the tense in the 'if clause' is the simple present, and the tense in the 'main clause' is the simple future:

'IF' CLAUSE (CONDITION) MAIN CLAUSE (RESULT)
If + simple present Simple future

If it rains, you will get wet

If you don't hurry, we will miss the train.

In these sentences, the time is the present or future and the situation is real. They refer to a possible condition and its probable result. They are based on facts, and they are used to make statements about the real world, and about particular situations.

We often use such sentences to give warnings:
If you don't leave, I'll call the police.
If you don't drop the gun, I'll shoot!

Examples:
If you drop that glass, it will break.
Nobody will notice if you make a mistake.
If I have time, I'll finish that letter.
What will you do if you miss the plane?

NOTE: We can use modals to express the degree of certainty of the result:

If you drop that glass, it might break.
I may finish that letter if I have time.

Must, have to and should: (Modals)

You must do your homework.
You must wipe your feet before you enter.
MUST: obligation is imposed by the speaker. The speaker has authority over the one that is spoken to and he/she exercises his/her power.
Must is also preferred to refer to ourselves (I must go now) and to express a strong advice or invitation (That's a picture you really must see).

You have to pass your exams if you want to succeed.
In England you have to drive on the left.
HAVE TO: obligation springs from circumstances or external rules. Something has to be done, whether the speaker likes it or not.

You should quit smoking.
You should remember these rules.
SHOULD is used to give advice. No obligation here, rather a recommendation from the speaker
