Intermediate Conditionals Review — Second and Third
B1-B2 Level
English Exercises is teacher-led by Charlie. About the teacher · How content is made
The key difference is timing: the second conditional imagines a different present or future ("If I were rich..." — but I am not rich now), while the third conditional imagines a different past ("If I had known..." — but I did not know). Mixing these two conditionals in one exercise tests whether you can quickly identify the time frame and choose the correct structure. This skill is essential for Cambridge B2 First, where second and third conditionals appear in key word transformations and open cloze exercises. Practising both types together builds the flexibility you need for natural English conversation about wishes, regrets, and imaginary scenarios.
Quick Rule
Second: If + past simple, would + base verb | Third: If + past perfect, would have + past participle
- 1.If I spoke French, I would apply for that job. (second — hypothetical present)
- 2.If she had taken the earlier bus, she would have arrived on time. (third — unreal past)
- 3.If we lived near the beach, we would go swimming every day. (second)
- 4.If they had known about the delay, they would have left earlier. (third)
- 5.If she hadn't been so nervous, she wouldn't have forgotten her lines. (third — negative)
