Although not common, any and some can be synonymous. Both words can be used in questions or statements that begin with "if". For example: If you need some money, I will gladly lend you $100.00. If you need any money, I will gladly lend you $100.00. Aline, your answer is quite good. You just need to be careful with subject/verb agreement. "There is some books" is incorrect because the verb "is" should be used to refer to a singular noun. "There are some books" is correct. If there were only one book, then "There is a book" would be correct.

We use any in interrogative and negative sentences. Example: There isn't any book in your house. Is there any book in your house? And we use some in affirmative sentences. Example: There is some books in my house. We use as when we are comparing thing literally... (in the fuction of) When I say: I work as a teacher, I'm saying that I REALLY work as a teacher Like: figurative sentence, similar of When I say: I work like a teacher, I'm saying that I work as much as a teacher, or with kids... The point is: it's figurative. It's not literal. I don't know if it's clear to you now... Maybe someone could explain better.

'Any' is also used to express a lack of preference or specificity. For example: (a) We can watch 'any' of the movies showing (this means there is no movie preference). (b) The boss could arrive at 'any' moment (this means the exact moment/time the boss would arrive is unknown). Some expresses a vague quantity. Examples (a) There are 'some' nice bars in town (the exact number of nice bars is not mentioned. It could be 3, 12 or 100). (b) 'Some' people like country music (this means there are people who like country music but not all people do and the number of people that like it is not known) 'As' and 'like' sometimes mean the same thing but often do not. For example: (a) Do 'as' I do and do 'like' I do, both mean, do what I do.

We use SOME and ANY with plural nouns and uncountable nouns. Some is generally used in positive sentences. Any is generally used in negative sentences. I have some information for you about flights to Paris. (Positive - Uncountable) I don't have any information for you about flights to Paris. (Negative - Uncountable) We met some friends for drinks after work yesterday. (Positive - Plural Countable) I didn't see any friends there on Thursday. (Negative - Plural Countable) I think he will have some time to speak to you today. (Positive - Uncountable) I don't think he will have any time to speak to you today. (Negative - Uncountable) You can also use SOME and ANY in a sentence without a noun if the meaning of the sentence is clear. I didn't eat any salad but Peter ate some. (salad) Sean took lots of photos of the mountains but Emma didn't take any. (photos) http://www.grammar.cl/Notes/Like_vs_As.htm LIKE The structure of the sentence is usually: VERB + LIKE + NOUN / PRONOUN. He speaks like a native speaker. She looks like a supermodel. AS The structure of the sentence is usually: AS + SUBJECT + VERB. Nobody sings as she does. They went to the party as they were. It is very common in American English to use LIKE instead of AS. However, it is generally considered informal to use it in this way. We play football like champions do. Another use of AS is to say what the role/function of a person/thing is. He started work as a carpenter. She used the tapestry as a decoration in her living room. LIKE vs. AS Be careful, in similar sentences that use LIKE and AS, the meanings of each sentence are very different. For example: As your boss, I must warn you to be careful. (I am your boss.) Like your boss, I must warn you to be careful. (I am not your boss, but he/she and I have similar attitudes.)
