Question 1

What grammar topics does this easy conditionals review cover?

Accepted Answer

This easy review exercise covers two foundational conditional types: the zero conditional and the first conditional. You will practise forming both structures and — more importantly — choosing between them in mixed exercises. The zero conditional uses present simple in both clauses for general truths and habits: "If you heat water, it boils." The first conditional uses present simple in the if-clause and "will" in the result clause for real future possibilities: "If it rains tomorrow, we will cancel the picnic." By combining both types in one exercise, you build the skill of identifying whether a sentence describes an always-true fact or a specific future event, which is a key distinction tested at A2-B1 level.

Question 2

Why is it important to practise zero and first conditionals together?

Accepted Answer

The zero and first conditional share the same if-clause structure — both use present simple after "if" — which is exactly why practising them together is so valuable. The difference lies entirely in the result clause: zero conditional uses present simple ("If you press this button, the door opens"), while first conditional uses "will" ("If you press this button, the alarm will go off"). Learners who study each type in isolation often struggle when they appear side by side, because the if-clauses look identical. Mixed exercises force you to focus on meaning — is the result always true, or is it a specific future possibility? — rather than relying on surface-level pattern matching. This distinction appears regularly in Cambridge B1 Preliminary gap-fill tasks.

Question 3

Why do we use present simple in the if-clause, not "will"?

Accepted Answer

In English conditional sentences, the if-clause usually does not use "will" for future predictions. The conjunction "if" already signals that the action is conditional and future-oriented, so adding "will" would be redundant. Say: "If it rains tomorrow" (correct), not "If it will rain tomorrow" (incorrect for predictions). However, "if + will" can express willingness or polite requests: "If you will wait here, I'll be right back." This rule applies to both zero and first conditionals, and also to time clauses with "when," "before," "after," "as soon as," and "until." The main clause (the result) can use "will": "If it rains, I will stay home." This present-simple-in-the-if-clause rule is one of the most commonly tested grammar points at A2 and B1 level.
