 if clauses Les conditional clauses of IF clauses comprennent deux types de phrases: 1- Une phrase subordonnée qui contient la condition IF et une seconde phrase qui est dite "result" clause qui contient le résultat. Il s'agit donc dans ce type de phrases, de conditions à réunir (1) pour que se produise un évènement, une action (phrase 2). La structure de ces phrases est la suivante:

  1.  Hypothèse simple ou 1st Conditional: Dans le cas d'une hypothèse simple.

   If + verbe au simple present dans la première phrase = futur -shall, will, may-  (dans le result clause). Note: Shall, will, may lorsqu'ils sont utilisés avec un verbe, ce dernier garde sa forme de base

          if clauses If it rains, everyone will/shall/may stay indoors
            S'il pleut, chacun reste à la maison

 2. Hypothèse incertaine ou souhait, vœux ou 2nd Conditional

 If + verbe au prétérit ou simple past tense  dans la première phrase) = conditionnel (would, should, might, could) dans le result clause

          if clauses  If it rained, everyone would stay indoors
             S'il pleuvait, chacun resterait à la maison (mais il ne pleut pas).

NB Lorsqu'on émet un souhait, un vœux, on utilise were à la place de was, même si le pronom personnel est "I" Ex. If I were you, i would accept the job, ou alors comme dit Beyonce, If I were a boy, i would travel...or dans les deux on n'est ni l'un ni l'autre, on émet juste des sohaits, des voeux, des propositions...

3. Hypothèse non réalisée ou 3rd Conditional:

If + verbe pluperfect (past perfect) (dans la subordonnée) = conditionnel passé ou conditional present perfect (result clause).

            if clauses If it had rained, everyone would have stayed indoors. 

if clausesNote: il existe une autre forme du 3rd Conditional. Ainsi au lieu d'utiliser If, on inverse plutôt le verbe comme l'indique la structure suivante: Had it rained, i would have stayed indoors


      Les phrases relatives (relative clauses) sont des courtes phrases avec des mots tels que who, which qui sont appelés des pronoms relatifs qui définissent ou décrivent des personnes, des choses, des animaux. Liste des pronoms relatifs.

  • Who/Whom/ to whom sont utilisés pour des personnes. Who est pronom relatif sujet alors que Whom est pronom relatif complément: Ex. The man who (qui) is coming is the director. The man whom (que) you saw is the director. The man to whom you spoke is the director.
  • Which/that sont utilisés pour des personnes, des choses, des animaux. Ils sont aussi bien complément que sujet. Ex. The bus which (qui) goes to Cairo leaves from here. The bus which (que) you saw goes to Cairo. The road that (que) we took led to an ancien temple.
  • Whose (dont) montre que quelque chose appartient à quelqu'un. The girl whose car had been stolen went to the police station. Notez que lorsqu'on utilise whose celui ci s'intercale entre deux mots que nous avons souligné.(girl & car)


relative pronoun use example
who  subject or object pronoun for people I told you about the woman who lives next door.
which  subject or object pronoun for animals and things Do you see the cat which is lying on the roof?
which  referring to a whole sentence He couldn’t read which surprised me.
