Second Conditional Sentences Quiz: Master Conditional Sentences

Study Notes

What are Conditionals?: Conditionals are statements that describe both hypothetical and real scenarios, often referred to as "if clauses" because they often begin with "if" or "when".

Zero Conditional:
- Expresses universal truths or when one action always follows another.
- Structure: if (or when) + present tense | present tense
- Example: If you heat water to 100°, it boils.
First Conditional:
- Expresses a future scenario that might occur.
- Structure: if + present tense | will (may/might/can/could/should) + infinitive
- Example: If you're free later, we can go for a walk.
Second Conditional:
- Expresses hypothetical or impossible situations in the present or future.
- Structure: if + past subjunctive | would/might/could + infinitive (simple or continuous)
- Example: If I won the lottery, I would travel around the world.
Third Conditional:
- Expresses an unreal situation in the past, with reference to the hypothetical outcome that would result also in the past.
- Structure: if + past perfect subjunctive | would (could/might) + perfect infinitive
- Example: If I had studied harder, I would have passed the exam.

Unless: Can be used instead of "if" in first and second conditionals, meaning "only if" or "except".
Mixed Conditionals: Can be used to combine the second and third conditional in one sentence, to describe a hypothetical situation in the past and its consequence in the present.

Zero Conditional: Use simple present tense in both clauses, not future tense.
First Conditional: Use simple present tense in the if-clause and simple future tense in the main clause.
Second Conditional: Use simple past tense in the if-clause and modal auxiliary verb in the main clause.
Third Conditional: Use past perfect tense in the if-clause and modal auxiliary verb in the main clause.
