Select the correct sentence: elle fait la voile. je fais le ski nautique en france. je fais la natation. il fait du tennis

Hi !

The correct sentence is = Il fait du tennis

In French, you always have to add a preposition
you can't say= he plays piano = il joue piano
but il joue du piano

so to be correct the other sentences should have been :
Elle fait de la voile
Je fais du ski nautique en France (du = contraction de = de le)
je fais de la natation

hope it helps !

It depends : )
if the narrator participates in the story (it’s a character of the story) then yes.
but if the narrator does’nt participate in the story (the narrator does not have a character) then no.
