Differences in the usage of any, a and some:

1. If it's a question or a negative sentence, fill in any (but what if it's a question asking the other person's opinion and hoping for a positive answer? To fill in some, such as:

Would you like some coffee? would you like some coffee ? ) like this, it is the situation of soliciting the opinions of the other party.

In your first question, "Is there any bread in the kitchen?" It means: Is there any bread in the kitchen? This sentence does not mean to ask for advice, but simply asks about a state.

2.some is used in affirmative sentences, which can be followed by countable nouns or uncountable nouns.

3.a is used in affirmative sentences, which can only be followed by countable nouns.

The key to judging whether to use a or some in affirmative sentences is: is the noun behind it single?

Number or plural, with a for singular, with some for plural or uncountable nouns.
