1 ANTE TODO Just as the subjunctive is required with expressions of emotion, influence, and will, it is also used with expressions of doubt, disbelief, and denial. Main clause Subordinate clause Dudan que su hijo les diga la verdad. The subjunctive is always used in a subordinate clause when there is a change of subject and the expression in the main clause implies negation or uncertainty.

There is no doubt that the Amazon is one of the longest rivers. Es verdad que Colombia es un país bonito. It’s true that Colombia is a beautiful country.

6 No creo que haya vida en el planeta Marte.
In affirmative sentences, the verb creer expresses belief or certainty, so it is followed by the indicative. In negative sentences, however, when doubt is implied, creer is followed by the subjunctive. No creo que haya vida en el planeta Marte. I don’t believe that there is life on the planet Mars. Creo que debemos usar exclusivamente la energía solar. I believe we should use solar energy exclusively.

7 Tal vez veamos la luna esta noche.
The expressions quizás and tal vez are usually followed by the subjunctive because they imply doubt about something. The word “que” is not needed with these two expressions. Quizás haga sol mañana. Perhaps it will be sunny tomorrow. Tal vez veamos la luna esta noche. Perhaps we will see the moon tonight.

8 Consider the following sentence: I doubt that I will do the homework
Consider the following sentence: I doubt that I will do the homework. Note: When you wish to express doubt, disbelief, or denial without a change of subject in a two clause sentence, Spanish speakers usually express it with an expression of certainty rather than doubt, disbelief, or denial in the first clause, and a negative statement using the indicative in the second clause. I believe that I will not do the homework. Creo que no haré la tarea.
