Type one conditional

Type 1 Conditional

Type 1 conditionals 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.

1. Form

In a Type 1 conditional sentence, 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 If it rains If you don’t hurry	Simple future you will get wet we will miss the train.

2. Function

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!

• 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:

In type 1 conditional sentences, you can also use modal in the main clause instead of the future tense to express the degree of certainty, permission, or recommendation regarding the outcome or outcome.

• If you drop that glass, it might break.
• I may finish that letter if I have time.
•  If he calls you, you should go.
• If you buy my school supplies for me, I will be able to go to the park.
