Futur dans les subordonnées de temps

Futur dans les subordonnées de temps?
Bien qu'il s'agisse d'un événement futur, l'anglais utilise souvent le présent ou le
present perfect immédiatement après
'when,' 'as soon as,' 'after.'
Ex. When she leaves, you will have more time .
ou When she has left, you will have more time.
1- 'I will phone you when I get home' est une phrase en 2 parties :
la partie principale ( 'I will phone you' )
et la partie subordonnée introduite par WHEN ( 'when I get home' ).
2- Le temps est le futur MAIS l'anglais utilise un PRESENT dans la subordonnée.
3- Un autre exemple ? ' What will you do when you are in the USA ?'
4- La même chose se produit avec
WHILE, BEFORE, AFTER, AS SOON AS, UNTIL ou TILL.
5- Exemple ? 'I am going to sleep a lot when I am on holiday'.
6- Quand on utilise le present perfect, une chose doit être réalisée avant l'autre. ( =>
Les 2 choses ne peuvent se produire ensemble ).
7- Exemples ?
a- 'When I have seen Betty, we'll have our tea.' ( = Je verrai Betty et ensuite nous
prendrons notre thé.) /
b- 'When I see Betty, I will ask her to have tea with us.' ( = Je verrai Betty et je lui
demanderai - en même temps - de prendre le thé avec nous. )
Test : appliquer ces 'règles' aux phrases proposées => mettre le présent ou le present
perfect dans la subordonnée.

When + futur ou présent ?
When, suivi d'un verbe au présent ou au futur?
When peut avoir deux sens :

1) When = lorsque, quand
Lorsque WHEN signifie LORSQUE, le verbe qui suit sera au présent en anglais (à la place
du futur en français)
Je serai professeur lorsque /quand je serai grand
I'll be a teacher when I AM big
2) When = interrogatif : quand, à quelle date, à quel moment?
Dans ce cas, le verbe au futur en français, sera également au futur en anglais.
Quand viendras-tu?
When will you come?
Pour bien faire l'exercice, posez-vous la question si WHEN signifie LORSQUE, ou bien A
QUEL MOMENT...
