Conditional sentences


Conditional Type
Keyword: Factual

Conditional type zero is used to talk about general truths, scientific facts or things which always happen under certain conditions.

FORM

If + Simple Present , S + Simple Present

S + Simple Present, If + Simple Present

Example

If I boil the water, bubbles appear.
Phosphorus burns if you expose it to air.

Note: You can use "when" instead of "if".


Conditional Type
Keyword: Real

Often called the "real" conditional because it is used for real or possible situations. These situations take place if a certain condition is met. It is possible and also very likely that the condition will be fulfilled. We don't know for sure whether the condition actually will be fulfilled or not, but the conditions seems rather realistic – so we think it is likely to happen.

FORM

If + Simple Present , S + Simple Future

S + Simple Future, If + Simple Present

Example

If I have enough time, I'll read the magazine.
I'll tell her if I see her.


Conditional Type
Keyword: Unreal

Often called the "unreal" conditional because it is used for unreal impossible or improbable situations. This conditional provides an imaginary result for a given situation. It is very unlikely that the condition will be fulfilled. Generally, Conditional Sentences Type 2 refer to an action in the present that could happen if the present situation were different.

In conditional type 2, we usually use in the if clause "were" instead of "was" even if the pronoun is I, he, she or it. "were" here is asubjunctive form.

Note "was" is also a possible form.

FORM

If + Simple Past , S + Would Base Verb

S+ Would + Base Verb, If + Simple Past

Example

If I were a millionaire, I would buy a mansion.
I would bring her back to life if I knew necromancy.


Conditional Type
Keyword: Impossible

Conditional Sentences Type 3 refer to situations in the past. They express hypothetical results to past given situations. These situations can never be real, because they refer to things in the past that cannot be changed.

FORM

If + Past Perfect , S+ Would + Have + Past Participle

S+ Would + Have + Past Participle, If + Past Perfect

Example

If he had been careful, he wouldn't have had that terrible accident.
She wouldn't have gone to her brother's house if he had been honest with her!
