FIRST CONDITIONAL EXERCISE 2 (ESL)

GRAMMAR REVIEW: First Conditional — Common Mistakes & Variations

You've now seen the basic first conditional pattern. Here are the things that trip up even learners who know the rule:

1. Using "won't" vs "don't" in the if clause
The negative if clause always uses don't/doesn't, not won't.
❌ If you won't hurry, we'll be late.
✅ If you don't hurry, we'll be late.

2. Questions in the first conditional
The question form simply inverts the result clause:
Will you come if I ask you?
If I bake a cake, will you have some?

3. Replacing "will" with other modals
The result clause doesn't always need will — other modals work too depending on meaning:
If you're tired, you can rest here. (permission/ability)
If it rains, we might cancel the trip. (possibility, less certain)
If you finish early, you should call me. (advice)

4. "Unless" as an alternative to "if not"
Unless means if not and can replace the negative if clause:
If you don't study, you'll fail. = Unless you study, you'll fail.

DID YOU KNOW? First conditional in everyday English

The first conditional is one of the most frequently used conditional structures in both spoken and written English — you'll hear it constantly in everyday conversation, news reporting, advertising, and political speech.

Advertisers use it heavily to create desire: "If you buy two, you'll save 20%." Politicians use it to signal promises and consequences: "If we win the election, we will cut taxes." Weather forecasters use it almost exclusively: "If the low-pressure system moves east, we'll see heavy rain by Thursday."

One interesting quirk: in very informal spoken English, especially American English, native speakers sometimes replace will with 'll contractions so consistently that the full form sounds oddly formal. "If you come, I'll be happy" sounds completely natural; "If you come, I will be happy" sounds slightly stiff unless you're emphasizing the will for contrast or insistence.
