Unreal Conditionals: Second and Third Types
These conditionals describe hypothetical or impossible situations. The second conditional imagines present/future scenarios, while the third conditional reflects on past events that cannot be changed.
Second Conditional
Used for unreal, imaginary, or unlikely situations in the present or future.
If + Past Simple (Если бы + Past Simple),
would + инфинитив (base verb)
Примеры:
- If I were president, I would change the education system.
- If we had more time, we would visit the museum.
- If you spoke Chinese, you could get that job.
Key Features:
- Uses past tense in if-clause but refers to present/future
- Often uses 'were' instead of 'was' for all subjects (more formal)
- Can use 'could' or 'might' instead of 'would'
- Expresses dreams, hypotheticals, or unlikely situations
Особые случаи:

Third Conditional
Used for impossible past situations and their imaginary results - things that cannot be changed.
If + Past Perfect (Если бы + Past Perfect),
would have + причастие прошедшего времени (past participle)
Примеры:
- If I had known about the traffic, I would have left earlier.
- If she had studied medicine, she would have become a doctor.

Key Features:

- Often used for missed opportunities
- Can use 'could have' or 'might have' instead of 'would have'
- In formal English, can invert subject and auxiliary ('Had I known...')
Особые случаи:
