"Non, je suis une fille."
Translation:No, I am a girl.
Basics are basics. One will eventually appreciate the basics are useful in maintaining your xp's if you have a busy day or are too tired to do the more challenging lessons BUT at least you are then doing SOME practice EACH day. The Tiny Cards app by duo is fun and simple for repetions AND excellent for learning forever the "la" et "le". Take encouragement as the longer you continue with DUO the more you will appreciate its subtleties. Sometimes you might have man's voice saying, "I am a girl." You will not forget such items that will make you laugh or inspire you to make a comment. Cheers HTH
Your ear will pick up on pronunciation more and more as you go along. I'd say je suis (which means "I am") sounds like when you're a kid on a swing set yelling, "weeeeeeee" only with a "juh" and a "s" sound infront of it: juh sweeeeee. A lot of questions will give you an option to repeat the audio. Hovering the mouse over the word might also give it's pronunciation on some questions as well as the meaning. If you don't know the answer, you can always just give it your best guess, and if you're wrong it will give you the correct answer. You aren't really penalized for wrong answers; it just repeats the question at the end of the lesson to make sure you learn it.

Reminder: There is one discussion thread per sentence but several types of exercises per sentence. Besides, your exercise was not recorded and nobody could see you while you were doing it.
So if something went wrong, you should give the details of the exercise, your answer and the system's response, so that we can help you or report a problem.
