We use a lot of, lots of (more informal), or plenty of before both plural (countable) and uncountable nouns. We normally use them in positive sentences.
She spends a lot of time watching TV.
We had lots of good moments together.
We’ve got plenty of time.
Of before noun; no at the end of a sentence
We must always use a lot of or lots of including of at the end. However, we can use the expressions a lot or lots (without of) at the end of a sentence.
‘How many beers did you have?’ ‘I don’t know; I had lots/a lot.’
I like her a lot.
I don’t want any more cake, thanks. I’ve had plenty.
(A) few/(a) little/a bit of
Few for countable; little for uncountable
We use (a) few before plural (countable) nouns and (a) little or a bit of (more informal) before uncountable nouns in affirmative, negative and interrogative sentences.
I have to do a few things this afternoon.
He always gets good results with very little effort.
A few means ‘some but not many; enough’, and a little means ‘some but not much; enough’ .
Few means ‘almost none; not enough’.
Normally, the difference between a few/little (WITH a) and few/little (WITHOUT a) is that a few/little is positive in meaning, and few/little is negative. Compare:
There’s little milk in the fridge; we have to buy more. (=Not enough; we need more)
‘Shall I buy some beers?’ ‘No, it’s OK, there are a few in the fridge.’ (=Enough; we don’t need more)
‘Do you speak English?’ ‘No, I speak very little English.’ (=Negative)
‘Do you speak English?’ ‘Yes, I speak a little English.’ (=Positive)
Some/any/no
Some in (+) and any in (?) and (-)
We use some in affirmative sentences and any in negative sentences and questions.
There isn’t any sugar in the cupboard.
Have you got any new friends?
I have some questionsto ask you.
No in (+)
We use no in affirmative sentences.
There are no biscuits left.
I have no questions to ask.
With both countable (plural) and uncountable
Some, any and no can be used before countable and uncountable nouns. But if we use them before a countable noun, the noun must be plural.
Are there any students in the classroom? (NOT )
There are no students in the classroom.
Some for offers and requests
We use some (NOT any) in interrogative sentences when we are offering or requesting (=asking for) something.
Would you like some help?
Can I have some tea, please?
None
None is a pronoun. It means ‘zero’. We use it in affirmative sentences as a pronoun to replace countable and uncountable nouns. This means that it’s not followed by a noun.
