Exprimer la cause et la conséquence : because, so, that's why

La cause : pourquoi ?

Mot	Construction	Exemple
because	+ sujet + verbe	I stayed at home because it was raining.

as / since	+ sujet + verbe (souvent en début de phrase)	As it was late, we went home.
thanks to	+ nom (cause positive)	I passed thanks to your help.
