This third first conditional exercise includes slightly trickier sentence patterns to push your accuracy further. If you are new to the first conditional, start with exercise 1.
GRAMMAR REVIEW: First Conditional — The Full Picture
You've now completed three first conditional exercises. Here's a consolidated reference covering everything you need to know:
The basic pattern: If + present simple → will + base verb If it rains, I will stay home.
Reversed clause order — same meaning, no comma: I will stay home if it rains.
Negative variations: If you don't leave now, you'll miss the bus. (not "won't leave") If she studies, she won't fail. (negative result = won't)
First vs second conditional — the key difference:
First conditional = the situation is real and possible: If I find my keys, I'll drive you. (I might actually find them)
Second conditional = the situation is hypothetical or unlikely: If I found a million dollars, I'd quit my job. (not likely to happen)
This distinction is one of the most tested grammar points at B1/B2 level — and the focus of our First or Second Conditional? exercises.
