First Conditional Exercise 3

level: Beginner (A1/A2)
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.

Complete each sentence with the correct first conditional form.

1. If Mary _________ now, she will arrive in Perth by 6:00 PM.
2. If we speak more slowly, they _________ us.
3. If my mom buys me that dress, I _________ it tonight.
4. If my neighbor is too loud, I ________ him to be more quiet.
5. If you ________ this flavor of ice cream, I will give you another one.
6. You will feel sick if you ________ eating candy.
7. I ________ a new flashlight if my old one stops working.
8. If the taxi ________ soon, we will miss our flight.
9. I ________ to bed if I feel tired.
10. Will you be upset if I ________ to the concert with you?

DID YOU KNOW? Conditional sentences in English proficiency exams

Conditional sentences are tested at every level of English proficiency — but the type of conditional tested shifts as you move up the levels. At A2/B1, examiners expect accurate first conditional usage. At B2, the focus shifts to distinguishing first from second conditional and using unless, provided that, and as long as as alternatives to if. At C1/C2, complex mixed conditionals and inversion structures like "Were I to leave now, I'd miss the meeting" come into play.

In Cambridge B2 First, conditional sentences appear in the Use of English Part 4 (sentence transformations) almost every exam — it's one of the most reliably tested structures. A common transformation task: rewrite "Study hard or you'll fail" using unless → "Unless you study hard, you'll fail."

Getting the first conditional completely right at this stage means one less thing to worry about as you move toward the trickier second and third conditionals — which are covered in the other exercises linked above.
