Video Learning "Conditional Sentences"
Conditional Sentences are usually known as Conditional Clauses or If Clauses. Conditional sentences are used to express that the action in the main clause (without if) can only happen if a certain condition (in the clause with if) is fulfilled. Conditional sentences are actually sentences with cause and effect relationship.
There are three types of Conditional Sentences.
Conditional Sentence Type 1
Example: If I know her, I will invite her
Pattern: If+Simple Present, Present Future
Meaning: It is possible that the condition will be fulfilled
Conditional Sentence Type 2
Example: If I knew her, I would invite her
Pattern: If+Simple Past, Past Future
Meaning: It is possible but very unlikely, that the condition will be fulfilled
Conditional Sentence Type 3
Example: If I had Known her, I would have invited her
Pattern: If+Past Perfect, Past Future Perfect
Meaning: It is impossible that the condition will be fulfilled because it refers to the past.
