Present continuous → Past continuous : Changement de temps pour l'action en cours rapportée.
- Vérifier que le verbe introductif est au passé: "said"
- Identifier le temps original: "am working" (present continuous)
- Appliquer le backshift: present continuous → past continuous
- Changer le pronom: "I" → "he"
"I am working hard," he said
Verbe introductif: "said" (passé simple)
Énoncé: "I am working hard" (présent continu)
"am working" est au présent continu
Doit être changé en passé continu à cause du backshift
Present continuous: am/is/are + -ing
Past continuous: was/were + -ing
"am working" → "was working"
"I" → "he"
Car l'énoncé est rapporté au sujet "he"
He said (that) he was working hard
Le mot "that" est souvent omis
He said (that) he was working hard
Le présent continu "am working" devient passé continu "was working".
• Present continuous → Past continuous : am/is/are → was/were + -ing
• Backshift condition : Applied when reporting verb is in past tense
• Pronoun change : I → he in reported speech
• That : Optional after "said"
Present perfect → Past perfect : Changement de temps pour une action achevée rapportée.
"I have finished the project," she told me
Verbe introductif: "told" (passé simple)
Énoncé: "I have finished the project" (présent parfait)
"have finished" est au présent parfait
Doit être changé en passé parfait à cause du backshift
Present perfect: have/has + past participle
Past perfect: had + past participle
"have finished" → "had finished"
"I" → "she"
"me" → objet indirect conservé
She told me (that) she had finished the project
Le temps parfait est maintenu mais reculé
She told me (that) she had finished the project
Le présent parfait "have finished" devient passé parfait "had finished".
• Present perfect → Past perfect : have/has → had + past participle
• Logical sequence : Past perfect shows action completed before reported moment
• Pronoun adjustment : I → she in reported speech
• Consistency : All tenses shift when main verb is in past
Future → Conditional : Changement de temps pour une action future rapportée.
"I will attend the meeting," he promised
Verbe introductif: "promised" (passé simple)
Énoncé: "I will attend the meeting" (futur simple)
"will attend" est au futur simple
Doit être changé en conditionnel à cause du backshift
Future simple: will + base verb
Conditional: would + base verb
"will attend" → "would attend"
"I" → "he"
Car l'énoncé est rapporté au sujet "he"
He promised (that) he would attend the meeting
Le futur devient conditionnel dans le discours rapporté
He promised (that) he would attend the meeting
Le futur simple "will attend" devient conditionnel "would attend".
• Future → Conditional : will → would + base verb
• Promise context : Shows commitment from past perspective
• Pronoun change : I → he in reported speech
• Modal shift : All modals follow backshift pattern
Can → Could : Changement de modal pour exprimer la capacité rapportée.
"I can speak French fluently," she mentioned
Verbe introductif: "mentioned" (passé simple)
Énoncé: "I can speak French fluently" (modal "can")
"can speak" utilise le modal "can"
Doit être changé en "could" à cause du backshift
Modal "can" → Modal "could"
"can speak" → "could speak"
"I" → "she"
Car l'énoncé est rapporté au sujet "she"
She mentioned (that) she could speak French fluently
Le modal "can" devient "could" dans le discours rapporté
She mentioned (that) she could speak French fluently
Le modal "can" devient "could" à cause du backshift.
• Can → Could : Modal backshift pattern
• Ability context : Shows capability from past perspective
• Modal consistency : All modals follow backshift pattern
• Base verb : Remains unchanged after modal shift
Past continuous → Past perfect continuous : Changement de temps pour une action en cours rapportée.
"I was reading a book," he explained
Verbe introductif: "explained" (passé simple)
Énoncé: "I was reading a book" (passé continu)
"was reading" est au passé continu
Doit être changé à cause du backshift
Past continuous: was/were + -ing
With backshift: had been + -ing (past perfect continuous)
"was reading" → "had been reading"
"I" → "he"
Car l'énoncé est rapporté au sujet "he"
He explained (that) he had been reading a book
Le passé continu devient passé parfait continu
He explained (that) he had been reading a book
Le passé continu "was reading" devient passé parfait continu "had been reading".
• Past continuous → Past perfect continuous : was/were → had been + -ing
• Duration context : Shows ongoing action from past perspective
• Backshift effect : Past tenses move further back in time
• Aspect preservation : Continuous aspect maintained with temporal shift
- Present → Past : Simple present becomes simple past
- Present Perfect → Past Perfect : Completed actions move further back
- Future → Conditional : Will becomes would
- Modals : Can→could, May→might, Must→had to
- Continuous aspects : Maintain aspect but shift time
• Universal truths : "The earth goes around the sun" → "He said the earth goes around the sun"
• Present reporting : "She says she likes coffee" (no backshift)
• Still current : "He said he lives in London" (if still true)
• Conditional in reported speech : Sometimes remains unchanged
- Applying backshift unnecessarily : "She says she lived in France" → Should be "lives" if still true
- Forgetting to change pronouns : "He said I was tired" → Should be "he was tired"
- Mixing direct and indirect word order : "He asked what did you do" → Should be "what you did"
- Incorrect modal backshift : "can" → "could" not "can" → "will"
- Le backshift s'applique principalement quand le verbe introductif est au passé
- Les vérités universelles ne subissent pas le backshift
- Les pronoms doivent être adaptés dans le discours rapporté
- Les modaux suivent des patrons spécifiques de backshift
