Problem with There's, there aren't + some/any

First of all, thanks everyone who is seeing my topic to help me

 Well, I know that There's is used to refer that something exists, for singular and There are is for plural.

 Some examples:

 There's a book here.

There are animals in the zoo

 The problem comes when my book says that sometimes I have to add also Some and Any in some sentences and I don't know why and in which cases I must add them.

 Explanation of my book

 ---------------------------------------------------------

There is/isn't There are/aren't

 The negative form of there is = there isn't 

There isn't a chat in here

 With uncountable nouns, we use there isn't any...

There isn't any furniture in the bedroom.

  With plural nouns we use there aren't any... (the negative form of there are)

There aren't any chairs in the bedroom

--

 OK, good explanation haha

Why There aren't any chairs in the bedroom and not "There aren't chairs in the bedroom"??

 The same case here, why: There's some information there and not "There's information here"??

 Thanks in advance, I see it plenty of times and I cannot understand it, the reason of that and in which cases I must use them.

 Thank you and sorry for my English, I'm trying to improve it 

 PD: If you can leave some exercises I will be glad with you

Thank you for your answer.

So, If I want to say that are chairs in here, What must I use?

There are chairs in here. (I think this is wrong)

There are some chairs in here. (I think this is the great sentence)

With gold:

There's some gold in that mine. (I think this is the great sentence)

There's gold in that mine (I think this is wrong)

Am I OK? In accord what you said, I think I'm ok now, but I really don't know.

In other words, with uncountable nouns, Must I use them with 'some and 'any' in negative and positive sentences?

 For example:

I have some new information for you or I have new information for you?

 There's not any water at the kitchen or There's not water at the kitchen?

Thanks a lot

I come across this problem too while teaching that structure in the classroom for biginners. But at the end I think that the rule is as follows:    any is used for negative plural , and plural interrogative

while some is used for plural affirmative form and it is used in case of uncountables.ok here are some eg.

*are there any curtains in the living room?

*yes, there are some.

*no, there aren't any.

for uncountables: for eg.

* would like some tea?   *there is some bread = we cannot say there is a bread. that is why it is used even with uncountables .

The problem comes when my book says that sometimes I have to add also Some and Any in some sentences and I don't know why and in which cases I must add them.

Add any when the sentence is negative.  Add any when the sentence is interrogative.  But, less often, interrogatives also take some.  If there is neither a negation nor an interrogation, you cannot use any.  Those that are crossed out are either not used or have special, non-typical uses.

Countable singulars. 

There is a chair in the kitchen.  There is some chair in the kitchen.   There is any chair in the kitchen.

There isn't a chair in the kitchen.  There isn't any chair in the kitchen  There isn't some chair in the kitchen.

Is there a chair in the kitchen?  Is there any chair in the kitchen?   Is there some chair in the kitchen?

Isn't there a chair in the kitchen?  Isn't there any chair in the kitchen?   Isn't there some chair in the kitchen?

__________ 

Countable plurals. 

There are chairs in the kitchen.  There are some chairs in the kitchen.  There are any chairs in the kitchen.

There aren't chairs in the kitchen.  There aren't any chairs in the kitchen.  There aren't some chairs in the kitchen.

Are there chairs in the kitchen?  Are there any chairs in the kitchen?  Are there some chairs in the kitchen?

Aren't there chairs in the kitchen?  Aren't there any chairs in the kitchen?  Aren't there some chairs in the kitchen?

__________

Uncountables.  Note the similarity of the patterns below with the patterns for countable plurals above.

There is milk in the glass.  There is some milk in the glass.  There is any milk in the glass.

There isn't milk in the glass.  There isn't any milk in the glass.  There isn't some milk in the glass.

Is there milk in the glass?  Is there any milk in the glass?  Is there some milk in the glass?

Isn't there milk in the glass?  Isn't there any milk in the glass?  Isn't there some milk in the glass?

_________

When the question is about a countable singular, the negative answer is typically in the plural:

Is there a chair in the kitchen?  Yes, there is a chair in the kitchen.

Is there a chair in the kitchen?  No, there aren't any chairs in the kitchen.

I have no idea if that helps you, but maybe it will.
