First conditional is used for:

• 100% true facts

• lies

• things we wish to happen

• things that are probable

Zero conditionals are used for:

• 100% true facts

• lies

• things we wish to happen

• things that are probable

• First conditional uses a modal

• Zero conditional uses two verbs

• First conditional uses past tense

When the subject is he, she, or it, you need to:

• use a modal verb

• put the verb in past tense

• put an 's' on the verb

• do nothing
