A – First Conditional/future time clauses The First Conditional ( If clause + Pres. Simple + Main Clause or Main clause +If clause ) is about the future and describes situations that are likely to happen.
You have to use a comma to separate the If clause from the main clause when the if-clause comes first, as in If she arrives in time, we’ll go to the cinema’.
________ _ Pre Intermediate – 12th June
In future time clauses, the present simple is used in phrases beginning with before, as soon as, after, until, unless and when and the main clause comes in the future simple. As soon as he gets home, I’ll call you. B -The Zero Conditional The Zero conditional is about something that is always true. Both verbs (If clause + Main Clause) are in the Present Simple, as in If he’s not at home by six, I call the school. You can use When/If in the zero conditional In case means ‘because it’s possible that...’. It’s related to precaution, as in I wear two watches, in case one of them stops. Unless means except if/if not, as in ‘I won’t go to the party unless you come and pick me up . I won’t go to the party if you don’t come and pick me up. She’ll have to move house unless she gets that job she’s applied for (= She’ll have to move house if she doesn’t get the job she’s applied for). We can use modals in the main clause of conditionals, as in If you want your kids to be independent, you shouldn’t protect them so much.’ Imperatives can be used in the main clause of the zero conditional, as in If you come home late, don’t make any noise, please.
When it rains, the streets flood. If deforestation keeps happening, the temperature will rise. Cities will be overpopulated if people keep on leaving the rural zone. If we change our throwing away policies, we may save the planet. If you think radiation is low, you are wrong.
