Conditional Sentence

A. Definition

Conditional sentences are statements discussing known factors or hypothetical situations and their consequences. Complete conditional sentences contain a conditional clause (often referred to as the if-clause) and the consequence. For example:

• If a certain condition is true, then a particular result happens.
• I would travel around the world if I won the lottery.
• When the water reaches 100 degrees, it boils

Types

There are four different types of conditional sentences in English. Each expresses a different degree of probability that a situation will occur or would have occurred under certain circumstances.

• Zero Conditional Sentences
• First Conditional Sentences
• Second Conditional Sentences
• Third Conditional Sentences

but today we'll be discussing three of them since the Zero Conditional Sentences already discussed on different occasions. first is 

Type one  Conditional

Definition

Type 1 conditional sentences used to say something that might happen in the future. That’s means if you use this conditional sentence, it means that you are sure that the assumption is still possible in the future. In 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

The formula is:

If + simple present, present future (will)

And

Present future + if +simple present

B. Example

‘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.

If I find her address, I’ll send her an invitation.

If Jiyong has the money, He will buy a Ferrari.

If they bully me, I will report them to the police.

If something happens, I will call you.

If you do not put salt in your cooking, the food will taste plain.

If you snatch her thing, she will cry.

Conclusion:

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

Type Two Conditional

Definition

Second conditional sentences are a type of conditional sentence that is used when the result or consequence has little hope of being realized even though it is unlikely. So it can be said that this second type of conditional sentence does not necessarily happen but it can also become a reality. The use of would / could / might serves to explain how big a condition will be. In IF Clauses Type II, we usually use ‚were‘ – even if the pronoun is I, he, she or it –.

The formula is:

If + Simple Past, the main clause with Conditional I (= would + Infinitive)

B. Example

 IF CLAUSE (CONDITION)👉MAIN CLAUSE (RESULT)

If + simple past 👉 would/could/might + bare infinitive

If I owned a zoo, I might let people interact with the animals more.

If I were you, I would continue my study.

If I had time, I would go with you.

If she met her mother, she would be very happy.

If it rained tomorrow, I would sleep all day.

If I were you, I’d tell him the truth.

If I knew her phone number, I would call her.

If you studied, you wouldn’t fail the test.

Conclusion:

The conditional sentence type 2 is used when the result/consequence of the condition has no or little chance of being realized because the condition is impossible to fulfill in the present (present unreal situation) or the condition is difficult to meet in the future ( unlikely to happen). Conditional Sentences Type II refers to situations in the present. An action could happen if the present situation were different. I don't really expect the situation to change, however. I just imagine „what would happen if …“

Type Three Conditional

A. Definition

A third conditional sentence is a conditional sentence that is used when the result/consequence of the condition does not have the possibility to materialize because the condition must have been met in the past. A third conditional sentence is a conditional sentence when a condition cannot possibly be realized at all. This can be described as a very impossible condition or just a dream or imagination. In this third type of conditional sentence, the sentence form uses the past perfect equipped with auxiliary modalities such as would, could, and should.

The formula is:

If + past perfect, would/should/could/might + have + past participle.

B. Example

IF CLAUSE (CONDITION)👉MAIN CLAUSE (RESULT)

If + past perfect 👉would/should/could/might+have + past participle

If you had remembered to invite me, I would have attended your party.

If he had talked to me, I would have listened to him.

If you had told me you needed a ride, I would have left earlier.

If I had cleaned the house, I could have gone to the movies.

If I had locked the car, the thief wouldn’t have stolen my car.

If David had married me, I would have been the luckiest woman in the world.
