Expressing Disagreement (Exprimer son désaccord)

In a communicative approach to language learning, the learner soon has to cope with a fundamental aspect of pragmatics: the argumentative and polemic function of language. From a pragmatic perspective, language is a tool we use not so much for describing or representing the world but for changing it, not for exchanging feelings of empathy, but for saying what we like and what we don't like, not just for expressing quiet satisfaction but for saying what is wrong, not for saying what we already know but for asking about what we want to know, not for explaining what we already have but for complaining about what we still lack and want to have: and for getting things done which would not be done if we did not ask for them and if we did not say why and how they have to be done.
