Sitesurf can you explain the use of the infinitive form of the verb courir in the sentence in the exercise. Is the general structure:
conjugated verb + noun phrase + infinitive
elle regarde sa mère mourir - she watches her mother die
and how would you say: she watches the water boil - elle regarde l'eau bouiller
As an aside I know that for the structure:
adjective / noun + preposition + infinitive
then generally, when the subject is a dummy subject you need the preposition de and when the subject is concrete you need the preposition à
The structure is an infinitive clause, which can replace a relative clause: elle regarde sa mère qui meurt.
Verbs of perception can all produce this type of construction:
- je vois, j'entends, je regarde, j'écoute, je sens... + infinitive/subject or subject/infinitive.
They are pronounced the same way, so you won't know if the person's friend is male or female. Sometimes, it is very convenient, but at other times, we need to make it clear and either use their first name "mon ami François" vs "mon amie Françoise", or change "ami/amie" to "mon copain/ma copine".
