1. If you had taken the necessary precautions, none of this would have happened. (In a type 3 conditional sentence, we use a past perfect tense in the if-clause and would have + past participle in the result clause.)

2. If I were you, I would get that mole examined. (In a type 2 conditional sentence, we use a past simple tense in the if-clause and would + infinitive in the result clause.)

3. If I won a lottery, I would spend all my time traveling. (When we use would + infinitive in the main clause, the verb in the if-clause should be in the past simple tense.)

4. Had I realized what you intended, I would not have given my permission. (‘Had I realized’ means the same as ‘If I had realized’. If I had realized what you intended, I wouldn’t have given my permission.)

5. If it hadn’t been for your help, I don’t know what I would have done. (We use a past perfect tense in the if-clause when would have + past participle is used in the main clause.)

6. Were she my daughter, I would not allow her to go out in that mini-frock. (In a type 2 conditional sentence we use a past simple tense in the if-clause and would + infinitive in the main clause. The clause ‘were she my daughter’ is actually a shortened form of the clause ‘if she were my daughter’.)
