Revision of the zero, first, second and third conditional The zero conditional We use the zero conditional to talk about usual occurrences. We make the zero conditional by using two clauses: the main clause and the conditional clause (which starts with if). The action in the main clause depends on the action in the conditional clause. If she is really frightened, she starts shaking. The verb in the conditional (if) clause is in the present simple tense or the present continuous tense. The verb in the main clause can be in the present simple tense, the present continuous tense or the imperative. If you hear a noise, it's the wind in the trees. You're imagining it. Examples 2 Listen to the examples. 1. If she tells you about the ghost, don't listen to her. 2. If she tells you she's not scared, she's lying. 3. If you hear a noise during the night, it's the dog barking. 4. If I am alone in the house, I get scared. The first conditional We use the first conditional to talk about events in the future. There is a good chance these events will happen, but this depends on another event or action taking place. She'll tell you if she feels scared. In the first conditional the verb in the main clause is in the future tense and the verb in the conditional clause is in the present simple tense. If she sees a ghost, she'll scream. 123
