How do you write Michelle est eleve dans une ecole secondaire americaine in the negative
https://translate.google.com is telling me you left out a WHOLE BUNCH of critical marks! Be sure to include them for your teacher!
Michelle est élevé dans une école secondaire américaine.
Go to that website, and make sure the left side is marked English and the right side is marked French.
Then type in the English for what you want to say. See what happens.
I don't know French, so you'll need to decide if you trust Google Translate!
