In the lesson on the partitive articles, they are listed as du, de l’, de la and des. When would you use the plural “des?” It seems that with uncountable nouns, you’re always talking about an amount or quantity of something, some sugar, some coffee, etc and would therefore always be singular. 

The example is given of something like “Tu achètes des épinards.” Here, “des” is used because “épinards” is a masculine plural noun. Is this the only time you use “des?” Otherwise, it’s really used as an indefinite article?

Thank you for any help!

Maybe it's just my Chrome browser, but I can't scroll to view the full table of words at the very end of the lesson

In this sentence, "période pendant laquelle apparaissaient les fortes chaleurs," is "apparaissaient" the correct tense? 

Shouldn't it agree with the noun "période?" 

Hence "période pendant laquelle apparaissait les fortes chaleurs?" 

"nous descendrons "te" rejoindre dans la cuisine"  This is how that appeared in the corrected dictation.  What is "te" in reflexive verbs?  Is this a misprint?
