Conditional Sentences are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.
Conditional Sentence Type 1
Conditional Sentences Type I refer to the future. An action in the future will only happen if a certain condition is fulfilled by that time. 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.
If Clause
Simple Present
S + V1 + O
S + tobe(is,am,are) + N/Adj
Result Clause
Future Tense
A + Will(shall,can,etc,..) + V1
Example
If I find her address, I’ll send her an invitation.
I want to send an invitation to a friend. I just have to find her address. I am quite sure, however, that I will find it.
Conditional Sentence Type 2
Conditional Sentences Type II refer 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 …“
If Clause
Past Tense
S + V2 + O
S + tobe(was,were) + N/Adj
Result Clause
Past Future
S + Would,should,could + V1
Example
If I were you, I would accept him
Fact : I am not you, so i will not accept him
I am not you, so I don't accept him
Conditional Sentence Type 3
Conditional Sentences Type III refer to situations in the past. An action could have happened in the past if a certain condition had been fulfilled. Things were different then, however. We just imagine, what would have happened if the situation had been fulfilled.
If Clause
Past Perfect
S + Had + V3
Result Clause
Past Future Perfect
S + would,could,should + have + v3
Example
If I had worked harder I would have passed the exam
(but I didn’t work hard, and I didn’t pass the exam).
