Explanation:
The present subjunctive is sometimes used as a form of imperative or in subordinate sentences after certain expressions to manifest a present or future action, according to the interpretation allowed by temporary complements.
Spanish governs the use of the present subjunctive in the following situations:
to make a negative assumption about the probability of an event in the present or in the future by means of the expressions: no + believe that, think that, seem to, consider that;
Example: no creo que el tiempo nos acompañe
to describe certain hypothetical conditions or present or future consequences by means of expressions such as: how, though, although, for more than, how much, so that ...;
Example: jugamos al baloncesto, por más que el tiempo no nos acompañe
to indicate the probability of an event in the present or in the future, with adverbs such as: maybe (s), maybe, probably, possibly, hopefully ...;
Example: quizas el tiempo no nos acompañe
behind the following phrases or expressions: before, without, when, just, after (of), as, until, while, as soon as;
Example: vamos a jugar al baloncesto hasya que el tiempo nos acompañe
to give a negative order (in all its forms). The positive imperative is only used to give an order with the 1st person of the plural and with the courtesy forms you / you.
Example: ¡no juegues al baloncesto con lluvia!
