The correct answer is "I bought some cheese, but I didn't buy any bread", which uses "some" in an affirmative sentence and "any" in a negative sentence.
Negation
A finite indicative verb (or its clause) is negated by placing the word not after an auxiliary, modal or other "special" verb such as do, can or be. For example, the clause I go is negated with the appearance of the auxiliary do, as I do not go. When the affirmative already uses auxiliary verbs (I am going), no other auxiliary verbs are added to negate the clause (I am not going). (Until the period of early Modern English, negation was effected without additional auxiliary verbs: I go not.)
Most combinations of auxiliary verbs etc. with not have contracted forms: don't, can't, isn't, etc. (Also the uncontracted negated form of can is written as a single word cannot.) On inversion of subject and verb (such as in questions), the subject may be placed after a contracted negated form: Should he not pay? or Shouldn't he pay?
Other elements, such as noun phrases, adjectives, adverbs, infinitive and participial phrases, etc., can be negated by placing the word not before them: not the right answer, not interesting, not to enter, not noticing the train, etc.
When other negating words such as never, nobody, etc. appear in a sentence, the negating not is omitted (unlike its equivalents in many languages): I saw nothing or I didn't see anything, but not (except in non-standard speech) I didn't see nothing. Such negating words generally have corresponding negative polarity items (ever for never, anybody for nobody, etc.) which can appear in a negative context, but are not negative themselves (and can thus be used after a negation without giving rise to double negatives).
Determinative
An important role in English grammar is played by determiners – words or phrases that precede a noun or noun phrase and serve to express its reference in the context. Determinative is a lexical category whereas determiner is a grammatical or syntactic function. In traditional grammar, determinatives form a subclass of adjectives. In the Cambridge Grammar of English Language, determinatives are considered to be a distinct primary lexical category (part of speech). Just as the determiner function is not always realised by determinatives, so many of determinatives can have other functions that that of determiner. The determinative three is determiner is three books, but modifier in these three books. Similarly, determinative much is determiner in much happiness but a modifier in much happier.
Demonstratives
Demonstratives are words, such as this and that, used to indicate which entities are being referred to and to distinguish those entities from others. They are typically deictic, their meaning depending on a particular frame of its reference. Demonstratives are often used in spatial deixis (using the context of the physical surroundings of the speaker and sometimes the listener), but also in intra-discourse reference - so called "discourse deixis" (including abstract concepts) or anaphora), where the meaning is dependent on something other than the relative physical location of the speaker, for example whether something is currently being said or was said earlier.
Demonstrative constructions include demonstrative adjectives or demonstrative determiners, which qualify nouns (as in Put that coat on); and demonstrative pronouns, which stand independently (as in Put that on). The demonstratives in English are this, that, these, those, and the archaic yon and yonder, along with this one or that one as substitutes for the pronoun use of this or that.
A1 / Elementary / Beginners
A CEFR A1 level English language user is considered a beginner. At this level, an individual is expected to have a basic understanding of the English language, including basic vocabulary and grammar. They should be able to understand and use simple phrases and sentences in order to meet basic needs and engage in simple, everyday conversations. They should also be able to understand simple instructions and signs in English.
At A1 level, they are able to understand and use familiar everyday expressions and very basic phrases aimed at the satisfaction of needs of a concrete type. They can introduce him/herself and others and can ask and answer questions about personal details such as where he/she lives, people he/she knows and things he/she has. They can interact in a simple way provided the other person talks slowly and clearly and is prepared to help.
