Let's review countable and uncountable nouns.
COUNTABLE: Things you can count: table, books, people, etc...
UNCOUNTABLE: Things that you cannot count: air, water, coffee....
However, there are certain words that seem to be countable, especially because they are countable in Portuguese. But, surprisingly, they are not. Here is the list:
INFORMATION
EQUIPMENT
LUGGAGE
ADVICE
IDENTIFICATION
EVIDENCE
...
Well, I think that these are the most incorrectly used words.
Therefore, you cannot use those words in plural. Informations, equipments, advices... WRONG, WRONG, WRONG! That's why I call these words "crazy", because in Portuguese, they are perfectly countable! In English, they cannot be used in plural.
So, let's see the quantifiers now.
COUNTABLE | UNCOUNTABLE |
MANY/FEW | MUCH/LITTLE |
A NUMBER OF | AMOUNT OF |
FEWER (THAN) | LESS (THAN) |
One, two, three.... | A piece of, two pieces of, three pieces of... |
So, you cannot say: "Let me give you 2 advices", but you can say "Let me give you two pieces of advice". I know, it does sound weird, but if you learn how to use, you get used to it, this new structure of "crazy" uncountable nouns.
I found this video on youtube about "Eminem's 10 pieces of advice for kids" on David Letterman's show:
There's also this video talking about the best piece of fitness equipment:
