This is not an English sentence, and why does the second verb take a subjunctive rather than an infinitive form?

No creo que ________ todos los deberes para el lunes. I don't believe to have done all my homework by Monday.HINT: Conjugate the yo form of "hacer" in El Pretérito Perfecto Subjuntivo

Hola Allison

Sentences introduced by an opinion in "negative" are followed by the subjunctive. Have a look at this lesson that will clarify your doubt:

Using the subjunctive with negative opinion phrases

The English typo has been corrected. 

Muchas gracias,

Thanks Inma, but I learned that if the same subject is in both clauses (No creo and hacer los deberes) it would trigger the infinitive in the second clause?

Hi Allison

That is correct in certain cases, for example:

"Yo quiero estudiar más" (same subject in both, infinitive) but 

"Yo quiero que (tú) estudies más" (different subjects, needs subjunctive)

Also with "hope":

"Yo espero ganar la lotería" (same subject in both, infinitive) but

"Yo espero que ganes la lotería" (different subjects, needs subjunctive)

Notice the absence of "que" in the sentences with the same subject.

In order to be able to use an infinitive with "Yo no creo que..." you need to get rid of "que". For example:

Yo no creo haber hecho todos los deberes para el lunes. (although this sounds a bit formal)

With "que", the only option would be:

Yo no creo que haya hecho todos los deberes para el lunes.

Saludos

OK thanks!

So "Yo no creo haber hecho todos los deberes" or "Yo creo haber hecho todos los deberes" are correct, albeit formal?

How has your day been?
