Explications
For et since sont deux mots très importants en anglais, et sont très souvent mal employés. Je te propose ici de t’expliquer très clairement comment on les utilise.
Nous utilisons la préposition for pour parler de la durée d’une action. C’est-à-dire la période pendant laquelle elle se déroule.
Nous utilisons la préposition since pour dire quand quelque chose a commencé, c’est-à-dire la date ou le moment auquel une action a commencé. On fait référence à un point dans le temps.
Exemples :
- They have been waiting for 2 hours.
durée - They have been waiting since 4pm. moment
- She has worked in this restaurant for 2 months. durée
- She has worked in this restaurant since last December. moment
duréeSince ne peut être utilisé qu’avec les temps parfaits (past perfect, present perfect continuous, etc.).
For quant à lui peut être utilisé avec tous les temps.
Exemples:
- He worked on his homework for two hours. Past simple
- She will walk for 2 hours tonight. Future
- He has been working since 7pm. Present perfect continuous
- They had worked since they were 14 before they retired Past perfect
