Conditional Sentences Questions with Solutions

There are four standard "if" patterns, each tied to a different degree of reality — a general fact, a real future possibility, a present hypothetical, or a past that didn’t happen. Here’s the approach, four fully worked examples covering each type, and a few to try yourself.

The approach, quickly

  • Zero conditional (general truths): If + present simple, present simple — "If you heat ice, it melts." True every time, not just hypothetically.
  • First conditional (real future possibility): If + present simple, will + base verb — "If it rains, I will stay home." A genuinely possible future situation.
  • Second conditional (present/future hypothetical, unlikely or untrue): If + past simple, would + base verb — "If I won the lottery, I would travel." Note: formal English uses "were" for every subject in this pattern ("If I were," not "If I was").
  • Third conditional (past hypothetical, didn’t actually happen): If + past perfect, would have + past participle — "If I had studied harder, I would have passed." Describes an unreal past.

Worked examples

1. Choose the correct form: If water freezes, it ___ into ice. (A) turns (B) will turn (C) would turn (D) would have turned

Solution

  1. This describes a general, always-true fact — the zero conditional, which takes present simple in both clauses.

Answer: turns

2. Choose the correct form: If it rains tomorrow, we ___ the match. (A) postpone (B) will postpone (C) would postpone (D) would have postponed

Solution

  1. This describes a real, possible future situation — the first conditional, which takes "will" in the main clause.

Answer: will postpone

3. Choose the correct form: If I ___ a bird, I would fly around the world. (A) am (B) was (C) were (D) will be

Solution

  1. This is a present hypothetical that isn’t true (second conditional) — formal English uses "were" for every subject in this pattern, not "was."

Answer: were

4. Choose the correct form: If she had left earlier, she ___ the train. (A) would catch (B) would have caught (C) caught (D) catches

Solution

  1. This describes an unreal past situation that didn’t happen — the third conditional, which takes "would have + past participle."

Answer: would have caught
