"quelquefois, je déteste l'automne parcequ'il y a trop de vent"
You say il fait beau/mauvais but you'll say il y a du vent/du soleil
As for you question, after expressions like "beaucoup", "peu", "trop", we use "de":Il y a du vent.
Il y a trop de vent.
Il y a beaucoup de vent.
Why did we drop the "le" (change du to de) when we added the adverbs? (Hope this doesn't need it's own thread!)
Thanks.
