The document provides examples of using countable nouns in singular and plural forms as well as uncountable nouns with the verbs "to be" and "there is/are". For countables singular, "there is" and "a/an" are used while countables plural use "there are" and "some/any". Uncountables take "there is" and "some/any". Questions are formed by placing the noun before "there is/are" and answers affirm or negate the presence of the noun.
