In the first conditional (type 1), we use the base form of the verb in the if clause (to wear, to rise, to ask) and the future simple tense in the main clause (will work, will not be, refuse).
In the zero conditional (type 0), we use the base form of the verb in both the if clause and the main clause (to cook, to concentrate, use, do not make).
