English Grammar – Conditionals and Reported Speech CONDITIONALS These are sentences containing ‘if’ (or similar expressions such as ‘when’) which refer to past, present and future possibilities. There are two clauses, the ‘if’ clause and the main clause, and either can come in the first part of a conditional sentence. For example: If I had the money, I would buy a new car; I would buy a new car if I had the money. The ‘if’ clause contains the condition that has to be satisfied before the action or state in the main clause can be realised. We can also think of the main clause as expressing the consequence. In the above example, the condition of my having enough money has to be satisfied before I can buy a new car. My buying a new car is the consequence. The five main conditionals are as follows: ZERO FORM: USAGE:
if/when + present tense, present tense It refers to actions and facts that are irrefutable. You can use ‘if’ or ‘when’ with no change in meaning When you boil water, you get steam. (Condition: boiled water; consequence: steam) Water turns to ice if you freeze it. (Condition: freeze water; consequence: ice)
FIRST FORM: USAGE:
if + present simple, will (‘will’ can be replaced by a modal verb. E.g. may, might, can, should, must) This talks about a ‘real’ situation in the future that is possible, probable or even certain, once the condition has been satisfied. If he studies hard, he will pass the exam. (Condition: hard study; certain consequence: passing the exam) She might buy it if she has enough money. (Condition: having enough money; possible consequence: buying it)
