We usually add –s to make a plural noun:
We add –es to nouns ending in –s, –ch, –sh, –ss, –x and –o:

Plural count nouns do not have a general determiner when they refer to people or things in general:
Computers are very expensive.
Do you sell old books?
But they may have a specific determiner:
Those computers are very expensive.
The books in that shop are very expensive.
Her sisters live there.
or a quantifier:
|some new books||a few teachers||lots of good ideas|
or a numeral:
|two new books||three wishes|
