"You have the time to shower and change."
Translation:Tu as le temps de te doucher et de te changer.
for those wondering why de is used, here is an explanation
in structures of the form:
adjective / noun + preposition + infinitive
you generally find the preposition is de especially for impersonal expressions with dummy subjects.
Il est important d'étudier. - It is important to study (the word it acts as a dummy subject).
il est bon d'exercer - it is good to exercise (the word it acts as a dummy subject).
Il est difficile de manger parce que j'ai mal à la gorge - it is difficult to eat because I have a sore throat
il ne serait pas content de manger un hamburger. - he would not be happy to eat a hamburger.
ils ont été forcés de partir - we were forced to leave.
Nous avons la permission d'entrer - we have permission to enter.
However, you need to use the prepositions à and pour in the following situations:
The preposition à is used If the infinitive conveys a passive meaning (a passive infinitive is where the subject receives the action). A guideline for determining if the infinitive conveys a passive meaning is as follows:
if the English translation to be + past participle of a verb makes sense then the infinitive conveys a passive sense
J'ai beaucoup de travail à faire- I have a lot of work to do.
Il a quelque chose à manger. - He has something to eat.
Ce problème est facile à résoudre. - That problem is easy to solve.
nous n’avons personne à prévenir - we have nobody to warn.
J'ai beaucoup de devoirs à faire. - I have a lot of homework to do.
contrast these sentences with the following:
je doit faire beaucoup de travail - I must do a lot of work (faire is being used in an active sense).
il veut manger quelque chose - He wants to eat something (manger is being used in an active sense).
After verbs such as être, y avoir, rester when English uses a passive infinitive to express a possible, desirable or necessary course of action, French uses à and the active infinitive
toutes ces fenêtres sont à péparer - All these windows are to be repaired.
in n’y a rien à faire - There is nothing to be done.
cela reste à decider - That remains to be decided.
use à + infinitive after le dernier (the last), le seul (the only), le premier (the first), and other numerals, and after a few adjectives showing tendency, fitness, and purpose, such as habile (skillful), lent (slow), prêt (ready)
Je suis pret à partir - I am ready to leave.
Je serais probablement le dernier à te le reprocher. - I would be the last one to blame you for that
Tu es le seul à pouvoir faire ça. - you are the only one able to do that.
The preposition pour is used when it expresses an intention, in other words when pour means in order to
je vais au parc pour jouer au football - I am going to the park to play football. (Here pour means in order to.).
ça va être utile pour apprendre le français - it is going to be useful for learning French.
Est-ce qu'elle a utilisé la voiture pour aller au centre-ville ? - Did she use the car to go to the city centre?
The preposition à is used: with certain nouns to express purpose or function
une salle à manger - dining room
de l'eau à boire - drinking water.
machine à laver - washing machine.
If you look at nicholas_ashley's post more carefully, in the first section (where he discusses adjective / noun + preposition + infinitive), he says "you generally find the preposition is de especially for impersonal expressions with dummy subjects."
This does not mean it is not used for real subjects, as is shown by the last three examples he gives in that discussion.
And, since none of the 5 following "situations" occurs in the phrase for this exercise, we ar left with "de".
Hope that helps
Thank you Lulularosa. It does make the murky waters somewhat clearer but I find it hard to imagine going thru a list of possibilities that long while trying to speak to someone. I am a native English speaker and I have never known all these terms that seem necessary to learn a new language. Impersonal or passive, transitive or reflexive or pronomial? My head is spinning.
Don't fuss about it, you'll learn it as you hear it and as you need it. And if you don't understand you'll ask a question and another grain of sand will be added to your language learning. And one day, hey presto, you'll open your mouth and speak and someone will understand! It's a process...
