When to use "de" and when to use "des"?
"des" changes to "de" in a negative sentence.
What about beaucoup? I thought it always has to have "de" after it?
"Beaucoup" is an adverb that modifies a verb:
Followed by "de", "beaucoup de" is a preposition, as "a lot" becomes "a lot of".
My ear is so bad. I kept hearing frites. And yeah, I could have read the text, but I'm trying not to.
Even with a bad ear, you may focus on the end of the word:
why not "My father won't eat lots of fruit"
Grammatically "won't" is a future and the French sentence is in present tense.
