"If you have a fever, you have to stay in bed."

Translation: Si tu as de la fièvre, tu dois rester au lit.

[GPDePolnay]

What is wrong with "Il faut rester au lit"? One is constantly having il faut suggested as an alternative to tu dois. Duo's inconsistency is a wonder to behold!

[Ben_K_MIller]

My thoughts exactly!! I try to use some variety instead of always saying «tu dois» and get punished :)

There is "A fever" not "the fever" right?

[Jojo553168]

In french we say avoir de la fièvre.

And in English we say have "a fever" not "the fever".
