First conditional: form
conditional clause
main clause
if + present simple
modal verb with future meaning (shall/should/will/would/can/could/may/might)
If he gets a job in Liverpool,
he’ll have to get up early. It’s a long drive.
If Sheila rings,
I might ask her to come over for dinner.
Warning:
We use the modal verb in the main clause, not in the conditional clause.
If a lawyer reads the document, we will see if we’ve missed anything important.
Not: If a lawyer will read the document…
Imagined conditions: the second conditional
We use the second conditional to talk about the possible result of an imagined situation in the present
or future. We say what the conditions must be for the present or future situation to be different.
If people complained, things would change. (People don’t complain at themoment.)
