    If clause and main clause

    All conditional sentences have two parts: the if clause and the main clause. It doesn’t matter which clause comes first, but when the if clause comes first, we should put a comma after it.

    • If it rains, we’ll stay home
    • We’ll stay home if it rains.

    If + present, future

    In the first conditional, the verb in the if clause is present, and the verb in the main clause is future (will).

    • If you don’t go to sleep, you’ll be very tired tomorrow.

    The if clause may have a present or a future meaning, but the verb is always in the present (NOT future)

    • If you will be a good boy tomorrow, mummy will buy you a present.
    • If you are a good boy tomorrow, mummy will buy you a present.

    Main clause: will, modal verb, imperative

    In the main clause, we can use may, might, can, must, or should instead of will.

    • If he doesn’t train harder, he may/might lose the championship.
    • If your room is tidy, you can leave.
    • If you want to lose weight, you must/should eat less sugary things.

    Or we can also use an imperative instead of will.

    • If you arrive after midnight, ring me on my mobile.

    Unless = if (not)

    We can also use unless in conditional sentences to mean if … (not)

    • I won’t go on holiday unless I save some money.
    • = I won’t go on holiday if I don’t save some money.

    When, as soon as, before, after, until

    When we use a verb after when, as soon as, before, after or until to talk about the future, we must use this verb in the present tense (NOT future). We use the future in the other part of the sentence.

    • I’ll retire when I‘ll be 70.
    • I’ll retire when I‘m 70.
    • I won’t call you until I will arrive.
    • I won’t call you until I arrive.

    Similar to first conditional

    Future time clauses are similar to the first conditional. There’s a main clause and a when/after/etc. clause. We use the verbs in these clauses in the same way as in the first conditional.

    We use a comma when the when/after/etc. clause is at the beginning of the sentence. But we don’t use a comma if the when/after… clause is at the end of the sentence.

    • I’ll retire when I’m 70. 
    • When I’m 70, I’ll retire. 

    We use the present in the when/after/etc. clause and we use the future in the main clause.

    • Before you go to sleep, daddy will tell you a story. 

    In the main clause, we can also use may, might, can, must, should or an imperative instead of will.

    • As soon as you finish, you can leave. 
    • After you arrive, call me.
