Conditionals

Type 0 conditionals are used to express a general truth or a scientific fact. In this type of conditional, we can use when instead of if.

If-clauseMain ClauseIf/When + present simple present simpleIf/when you mix white and black paint, you get grey.Other examples:

1. If you heat water, it boils.

2. If it rains, you get wet.

Type 2 conditionals (unreal present) are used to express imaginary situations which are contrary to facts in the present and, therefore, are unlikely to happen in the present or future. We can use either were or was for all persons in the if-clause. We can also use the structure If I were you to give advice.

If-clauseMain ClauseIf + past simple / past continuous would/could/might + present bare infinitiveIf I had a better agent, I would get better acting offers.Other examples:

1. If she knew the answer, she would tell me.

2. If I was travelling around Europe, I would travel by train.

Type 1 conditionals are used to express a real or very probable situation in the present or future.

If-clauseMain ClauseIf + present simple future simple, imperative, can/must/may etc + bare infinitiveIf I finish this job before Friday, I will/might/etc go to a spa at the weekend.Other examples:

1. If you don't hurry, we will miss the train.

2. If I pass my exams, I will go on a long holiday.

When the hypothesis comes before the main clause, we separate them with a comma. When the main clause comes before the if clause, then we don't use a comma to separate them.

Note: with Type1 conditionals we can use unless + affirmative verb (= if + negative verb).

e.g. I will not be in a position to come unless someone buys my ticket.(= if someone does not buy my ticket.)
